About this service

Summary

I build and ship end-to-end web products, owning everything from backend systems to polished user-facing experiences. I’ve worked closely with founders, designers, sales, and GTM teams to translate real customer needs into shipped features by leading projects, running sprints, and iterating through direct user feedback. My focus is on performance, clarity, and maintainable systems that scale as products grow.

What's included

Modern Web Experience
Build fast, interactive web apps with React and Next.js, using server-side rendering and code-splitting to keep performance high. Lean on React’s component model for clean, maintainable code, and Next.js for routing, data fetching, and production-ready defaults.
Backend & Infrastructure
Build reliable backends with Node.js, using frameworks like Express for structured APIs. Pair with BaaS platforms such as Supabase or Firebase to accelerate development, handle auth, and enable real-time features.
Cross-Platform Mobile App
Ship polished iOS and Android apps from a single codebase using React Native. This approach speeds up development, reduces maintenance overhead, and keeps the experience consistent across platforms, while still allowing native integrations when performance or platform-specific features matter.
