As a senior full-stack developer with 10+ years of professional experience, I specialize in designing, building, and deploying modern web and mobile applications — with a strong focus on AI-integrated development workflows and rapid delivery.

My core stack includes React, Next.js, React Native, TypeScript, and Node.js, paired with SQL / NoSQL Databases (Postgres, Firebase, Supabase) and cloud platforms like AWS, Google Cloud, and Vercel.
I cover the full lifecycle: architecture, infrastructure, testing, CI/CD, and DevOps.

What sets me apart is how I work:
I leverage AI-powered tooling (Claude Code, MCP servers, n8n automation) as a core part of my engineering process. This lets me ship complex projects significantly faster — for example, a recent Bubble.io → Next.js production migration delivered solo in roughly 10 weeks.

Beyond hands-on development, I support startups and innovation-driven teams as a freelance tech advisor or interim CTO. I help translate business goals into scalable, pragmatic tech strategies and enjoy collaborating closely with product, design, and business stakeholders.

I'm passionate about clean architecture, modern frameworks, and the practical potential of AI/LLM technologies to create tangible business value.
