What I do

Specialized in building performant, scalable web applications from concept to deployment.

  • Frontend Development

    Building responsive, high-performance web apps with React, TypeScript, and modern tooling. Pixel-perfect implementation from any design system.

  • Full-Stack Solutions

    End-to-end development from database to UI. RESTful APIs, Node.js backends, and seamless frontend integration for complete products.

  • UI/UX Implementation

    Translating complex designs into clean, accessible code. Animations, micro-interactions, and responsive layouts that delight users.

  • AI Automation

    Integrating AI-powered workflows, chatbots, and automation pipelines. From LLM integration to intelligent data processing.

Process

Discovery Call

We discuss your project goals, requirements, timeline, and budget to ensure we're a perfect fit. I ask the hard questions upfront so there are no surprises down the road.

Technical Evaluation

I analyze the technical scope, define architecture, and provide a detailed estimate with milestones. You get a clear roadmap before a single line of code is written.

Implementation

Agile development with regular updates, code reviews, and iterative feedback loops. You see progress weekly — not just at the end. Every sprint ships working software.

Delivery

Final testing, deployment support, documentation, and knowledge transfer to your team. I don't just hand off code — I make sure your team can own it confidently.
