Websites, mobile apps, AI agents, and custom CRMs we've shipped with founders and operators. Real products, in production, doing the job they were built for.












































We rebuilt the home of a movement.
Ambition without the burnout. We redesigned happyhustle.com into an experience that doesn’t just describe the philosophy — it makes you feel it, and shows you exactly where to step in.
The hero leads with the promise — the proven system to Happy Hustle your dream reality — over full-bleed motion, so the movement’s energy lands before a single word is read.
Ten life alignments become an interactive centrepiece instead of a bullet list — each one a card you can explore around a living core, turning an abstract idea into the reason to stay.
From the Company Happiness Program to the monthly club benefits, each product line got a dedicated, high-contrast section with a single, unmissable next step.
Camp Montana and the experiential masterminds are sold on emotion — big imagery, real faces, and one confident call to explore the cohort.
A living “now playing” header sits above the numbers that matter — episodes, global rank, streams, and cadence — so credibility is felt, not claimed.
Memento mori. A stark, beautifully art-directed reminder — 18,250 days left — turns reflection into action and drops the visitor straight into the assessment.
Balance is the new hustle.
Happy Hustle · Est. 2020
Skip-traced data, refreshed daily.
Phantom Data ships verified mobile numbers, emails, and property records for sold callers and lead-gen teams — a 97% hit rate, billed per record, no subscription required.
Every record is mobile-verified and TCPA-scrubbed, then refreshed against the same providers competitors drop as “aged” — a 97% verified mobile hit rate, not a stale list.
Mobile-first contact data with full property and ownership context — owner name, address, property value, equity, mortgage type — ready for Mojo, CallTools, or any API-compliant SMS broadcaster.
One source of truth for cold calling, direct mail, door-knocking, and SMS/RVM — no re-exporting, no mismatched lists across tools.
A $9.99 trial, pay-as-you-go, or a monthly subscription. Same cache, same scrubbers, same providers on every plan — only the volume changes.
Real operators on why fresh, verified data beats the stale lists they used to dial — hit rates up, wasted dials down.
First-time customers start at $9.99 — no subscription, cancel anytime, and keep the records even if you leave.
Stop buying stale data.
Phantom Data · Skip-traced data, refreshed daily
Flyt: a white-label coaching management platform that turns executive coaching into measurable business outcomes.
The Roll is the team behind Flyt, a coaching management platform for individual coaches, coaching firms and enterprises running executive coaching programmes. Flyt handles scheduling and booking, AI-assisted session notes and transcription, progress tracking and impact reporting, and plugs into HR systems, calendars and video tools, with bank-grade security and EU data residency.
We delivered full stack application development across the platform, building out the product alongside the founding team so Flyt could prove coaching ROI with evaluation frameworks tied to business outcomes rather than vanity metrics.
Full stack Laravel engineering for a fleet coaching platform that turns driving data into better drivers.
AdvocacyAI runs a fleet coaching platform: fleet operators get visibility into how their drivers perform on the road and a structured way to coach them toward safer, more consistent driving.
We delivered full stack Laravel development for the platform, shipping the features fleet managers and drivers rely on and keeping the codebase in shape as the product grew.
An always-on AI agent that meets every inbound lead the moment it arrives.
Scale With Funding’s growth was capped by response time: leads landed on the website and in the inbox faster than the team could reply, and the ones that waited went cold.
We designed and shipped an AI agent system that engages visitors directly on the site and picks up inbound conversations across email and SMS — qualifying, answering, and routing automatically so every opportunity gets a fast, on-brand response.
Inbound demand came in through several channels at once, but follow-up depended on a human being free to reply. Outside business hours — and during any spike — leads sat unanswered long enough to lose interest.
A conversational AI agent embedded on the website, wired into the same pipelines that handle email and SMS. It understands intent, answers common questions, captures the details the sales team needs, and hands off cleanly when a human should take over.
Tech lead and fractional CTO for a Shopify supplement brand trusted by more than 110,000 customers.
Upgraded Formulas sells stabilised nano-mineral supplements (magnesium, zinc, iron, potassium and targeted blends for sleep, hormones and thyroid) alongside at-home hair tissue mineral analysis, to a community of over 110,000 customers. The business runs on Shopify, with personalised assessments, benefits-based shopping and educational content layered on top.
We stepped in as tech lead and fractional CTO: setting technical direction, owning vendors and releases, and modernising the Shopify store in place rather than through a risky replatform. Senior engineering the founders could lean on without building an in-house team.
UI/UX design for Fortify, Exsurgo's athlete-development platform that turns assessment data into coaching decisions.
Fortify is the software arm of Exsurgo, an athlete-development ecosystem that pairs performance-measurement hardware with coaching expertise. Exsurgo has assessed more than 4,500 athletes and sold over 2,500 devices, and Fortify is where that data lands: assessment results, training information, wearable metrics and athlete feedback, brought together into actionable insights for coaches.
We designed the UI/UX for the app, shaping how coaches and athletes move through dense performance data. Clean, intuitive screens that make the numbers readable at a glance instead of a spreadsheet to decode.
The lead-generation engine behind instant online valuations for a network of 4,000+ UK estate agents.
ValPal gives UK estate agents an instant online valuation tool that turns homeowners browsing an agent's website into vendor and landlord leads. Around it sits a full lead-generation and nurturing suite: automated follow-up, chatbots, lead qualification and AI voice and SMS, used by a network of more than 4,000 agents, some of whom report 20 to 30 valuation leads a week from the tool.
We built the advanced lead-generation system in Laravel and React and took on the tech lead role, owning the architecture, the releases and the day-to-day engineering direction as the platform grew.
DevOps and feature delivery that kept a complex lead-generation SaaS stable while it scaled.
Consulti.ai runs a lead-generation SaaS platform with a lot of moving parts, and customers depend on it running every day. Growth put pressure on the infrastructure at the same time as the roadmap kept asking for new features.
We handled extensive DevOps for the platform, covering infrastructure, deployments and the reliability work behind them, and rolled out new features for the application, so the product kept shipping without the platform wobbling under load.
From concept to a live product: end-to-end development and launch of the Canada Verified app.
Canada Verified needed their application taken from an idea to something real: designed, built, tested and launched, not left as a prototype that stalled before reaching users.
We built the app end to end, from initial concept and scoping through development and release, and helped get it launched as a live product so the team could focus on growing it.



Ongoing backend Laravel development as a dependable extension of a careers platform's engineering team.
Clubhouse Careers runs a careers platform in the staffing and recruiting space, with an existing Laravel codebase that needed steady, senior backend capacity rather than a rewrite.
We provide ongoing backend development inside their stack, shipping features on a regular cadence and acting as an extension of their engineering team, with no hiring overhead on their side. We also build and run our own applicant-tracking product, so the recruiting domain is one we know from the inside.
An AI PowerPoint plugin that generates full presentations from inside the tool people already use.
Arc is an AI productivity company whose users live in Microsoft PowerPoint. Rather than pull them out to a separate web app, the product needed to meet them where they already work.
We built an AI-powered presentation generation system and delivered it as a native PowerPoint plugin: users describe what they need, and the system drafts the deck, structure, slides and content, directly inside PowerPoint, ready to edit.
An AI sales agent that answers every inbound lead in under a minute, follows up automatically and qualifies before sales gets involved.
Parabolic Growth sells an AI-powered sales agent to high-value service businesses, from wealth management firms and dental and orthodontic practices to cosmetic clinics and health-insurance brokers, where a slow reply to a new lead is a lost customer. The promise is zero leads falling through the cracks: instant SMS and email responses, multi-touch follow-up, 24/7 coverage and a unified dashboard for every conversation.
We built the AI lead qualification system at the core of the product. It handles the conversations, scores and qualifies each lead, and only hands over to the sales team once a prospect is worth their time.
The live network that connects 30,000+ union linemen with storm-call work the moment the grid goes down.
Tramp GPS is a mobile platform for the electrical trades. When a storm takes out the grid, linemen and storm contractors across the US need to know where the work is, sign up fast and coordinate with each other. The app carries storm-call alerts and job postings (1,200+ posted so far), direct messaging, union local information, wage and contract data and a vendor directory, free for its 30,000+ union members.
We built the mobile app and continue to serve as the ongoing CTO for the project: infrastructure, analytics and releases, and the product direction that keeps the community growing.
Primed Presence: a leadership AI that lets managers work through challenges and rehearse hard conversations before they happen.
Presence on Purpose is a leadership development company built on three pillars: purposeful presence, impactful leadership and cultural transformation. Its founders point to a gap. Most leaders receive no structured development, and traditional coaching runs from $500 to $5,000 a session.
We built their leadership AI system, Primed Presence, as an affordable alternative to that. Leaders bring a real situation from their job, work through it with the AI and rehearse the upcoming conversation with an employee, so they walk into the meeting prepared rather than improvising.
Senior engineering that got a financial forecasting application over the finish line.
Bridge Forecasting builds financial forecasting software, where periods, reconciliations and audit trails have to be right and the logic has to be traceable. The application was well underway but needed senior hands to reach release.
We jumped in with senior full stack engineering inside the existing codebase, no rewrite, closing out the remaining work and getting the product to the finish line.
One platform for test prep and college admissions: practice tests, scholarship matching, application planning and vetted mentors.
College Prep System combines test preparation and college admissions guidance in a single platform for high-school students and their parents. It covers ACT, SAT, Digital SAT and PSAT practice with question-type ranking to target weak spots, college search and deadline organisers, cost calculators, a résumé builder, scholarship matching, and Mentor.Space, a marketplace of vetted tutors and advisors.
We delivered full stack application development across the product, building out the tools students use to plan, practise and apply so the team could keep expanding what the platform offers.
A mobile app that helps California homeowners get, and keep, their homes insured against wildfire.
Wuuii, whose product lives today at madronus.com, tackles a growing California problem: homes in wildfire zones that insurers will not cover. The service offers self-inspections, professional inspections by NFPA-certified specialists, treatment plans and Wildfire Prepared Home certification, work that can cut insurance premiums by up to 30% and has covered 10,000+ properties.
We built the mobile application that brings that process to homeowners' phones, and we serve as the mobile development team and CTO for the project, from the first release onwards.
A mental health and wellbeing app that helps people take control of life's ups and downs, built in Flutter for iOS and Android.
AIME (Cyberlimbic Systems Ltd, UK) puts science-backed support for depression, anxiety, social anxiety, stress, body image and relationships into one app: guided journeys, mindfulness, journaling, mood monitoring and a daily routine people build for themselves.
We built the AIME app in Flutter for iOS and Android, working inside their product team alongside their senior tech lead for more than six months. That meant shipping features every week in an app where privacy and a calm, trustworthy experience matter as much as the code.




We worked with Cagri for a little over 6 months and were absolutely thrilled with his performance and skills. Beyond being talented on a technical level, I was particularly impressed by his commitment and work ethic. He got things done quickly, asked questions when tasks were not clear and brought a positive attitude to the team. Would recommend to any team!

A HIPAA-compliant practice ERP for a growing medical practice: one place for reporting, marketing attribution, billing analytics, patient communication and AI assistants.
Blue Sky MD is a physician-led medical practice in Asheville, North Carolina. Like most growing practices, its data lived in separate places: eClinicalWorks for visits and billing, ad accounts for marketing, website forms for new inquiries, and phones and inboxes for patient conversations. Nobody could see in one place which campaigns filled the schedule, or how the practice was really doing week to week.
We're building the practice's operating platform on HIPAA-eligible Google Cloud services, under a signed Business Associate Agreement. It brings every system into one secure workspace and puts reporting, attribution, billing analytics, patient communication and AI assistants on top of it, for the whole team.
