Discipline

Web Dev
Design First

I build web applications with a product design first approach — meaning every engineering decision starts from the user's perspective. My process blends deep user research, business strategy, interface design, and full-stack engineering to create products people genuinely want to use.

Every interface I build is engineered to maximize user adoption, engagement, conversion rates, and business efficiency — because code that doesn't serve real people is just overhead.

User Research User Experience Wireframing Information Architecture Business Workflows UI Systems Design Systems Accessibility Responsive Design Rapid Prototyping Full-Stack Implementation AI Integration SaaS Architecture API Design Business Automation
🔍
Research & Strategy First
Every product starts with understanding users, business goals, market context, and competitive landscape. Design without strategy is guesswork.
🏗
Architecture Before Interface
Information architecture and business workflow mapping come before visual design. The structure defines the experience, not the other way around.
⚡
Built to Perform
Production-grade implementations with Lighthouse 100 scores, WCAG accessibility compliance, and sub-second load times on every device.
📊
Analytics-Driven Iteration
PostHog funnels, session recordings, and A/B testing feed every design iteration. Ship, measure, and improve — continuously.
🤖
AI-Native by Default
Every product is designed with AI-assisted workflows baked in from day one — not bolted on later. OpenAI, embeddings, and intelligent automation are first-class design considerations.
