UI/UX Design That Ships Products People Love

We don't just build software — we design experiences. Our design team works hand-in-hand with engineering to create interfaces that are beautiful, intuitive, and built to convert.

TL;DR

SlashDev offers full-spectrum UI/UX design — from user research and wireframing to high-fidelity prototypes and design systems. Because our designers sit alongside our engineers, what we design actually gets built — pixel-perfect, on time, and ready to scale. We've designed for SaaS platforms, mobile apps, AI products, and marketplaces across every industry.

Why design and engineering should never be separated

Most agencies hand off a Figma file and walk away. Then engineering builds something that looks 70% like the design, the interactions don't quite work, and edge cases weren't considered. At SlashDev, our designers and engineers work in the same team, the same sprint, the same Slack channel. What gets designed gets built — exactly.

Our design capabilities

We cover the full design lifecycle — from understanding your users to delivering production-ready assets that your engineering team (or ours) can implement immediately.

  • User Research & Discovery — stakeholder interviews, user journey mapping, competitive audits, and persona development. We understand your users before we draw a single pixel.
  • Information Architecture — site maps, user flows, content hierarchies. We structure your product so users find what they need intuitively.
  • Wireframing & Prototyping — low-fidelity wireframes for rapid alignment, then interactive prototypes in Figma that feel like the real product.
  • Visual Design & UI — high-fidelity interface design with a focus on clarity, consistency, and brand expression. Every screen, every state, every breakpoint.
  • Design Systems — component libraries, token systems, and documentation that keep your product consistent as it scales across teams and features.
  • Interaction & Motion Design — micro-interactions, transitions, and animations that make your product feel alive and guide users through complex flows.

What we design

Our design team has delivered for every product type and industry. Here's where we do our best work:

  • SaaS Platforms — complex dashboards, data-heavy interfaces, onboarding flows, and admin panels that make power tools feel simple.
  • Mobile Applications — iOS and Android native design, responsive PWAs, and cross-platform experiences that feel right on every device.
  • AI Products — chat interfaces, agent dashboards, prompt builders, and AI-powered tools that make complex technology accessible.
  • Marketplaces & E-commerce — product discovery, search UX, checkout optimization, and seller tools that drive transactions.
  • Internal Tools & Portals — enterprise software that people actually want to use. CRMs, ERPs, reporting tools, and operational dashboards.
  • Marketing & Landing Pages — high-converting landing pages, marketing sites, and brand experiences that tell your story and drive action.

How we work

Our design process is fast, collaborative, and deeply integrated with engineering. Here's what a typical engagement looks like:

  • Week 1: Discovery & Research — we audit your current product (if it exists), interview stakeholders, review analytics, and map out user needs and business goals.
  • Week 2: Architecture & Wireframes — we structure the product with user flows and wireframes, validating the approach before committing to visual design.
  • Weeks 3–4: Visual Design & Prototyping — high-fidelity screens in Figma, interactive prototypes for testing, and iteration based on your feedback.
  • Ongoing: Design System & Engineering Handoff — we build or extend your design system with production-ready components, specs, and documentation.
🎯 Design + Engineering

Because we're also an engineering studio, we can take your design straight into development — no handoff friction, no lost-in-translation moments. Design to production in one team.

Why clients choose SlashDev for design

We're not a traditional design agency. Here's what makes us different:

  • Designers who understand code — our designers know what's feasible, what's expensive, and what's going to break on mobile. They design with engineering constraints in mind.
  • Speed without sacrifice — first concepts in 48 hours, full design systems in weeks. We move fast because our process is proven.
  • Conversion-driven thinking — every design decision is grounded in user behavior and business outcomes. We design for results, not awards.
  • Seamless engineering handoff — because our designers and engineers work together, there is no handoff. The team that designs it builds it.
  • Scale-ready systems — we don't design one-off screens. We build design systems that grow with your product and team.

Design + engineering: better together

The real magic happens when design and engineering operate as one unit. Here's what that looks like in practice:

Frequently Asked Questions

Do you only design, or do you also build what you design?

Both. We're a full-service design and engineering studio. We can deliver just design (Figma files, prototypes, design systems) or take the project all the way through to a production application. Most clients choose the full package because the quality is significantly higher when the same team designs and builds.

What tools do you use for design?

Figma for all UI/UX design and prototyping. We also use FigJam for workshops, Lottie for animations, and our own component libraries built on Radix UI and Tailwind CSS for design-to-code consistency.

How much does UI/UX design cost with SlashDev?

Design engagements typically start at $5,000 for a focused project (landing page, feature redesign) and scale to $25,000–$75,000+ for full product design with design systems. We scope every project individually based on complexity, timeline, and deliverables.

Can you redesign an existing product?

Absolutely. Many of our engagements are redesigns. We audit the current experience, identify the highest-impact improvements, and redesign incrementally so you can ship improvements without a risky big-bang relaunch.

How do you handle responsive design?

Every design we deliver is responsive by default. We design for desktop, tablet, and mobile breakpoints — and because our engineers implement the designs, we ensure the responsive behavior works perfectly in production, not just in Figma.
