What I'm looking for

I’m looking for a team where I can lead full-stack delivery, design scalable systems, and ship with CI/CD—using Web2, Web3, and AI to build reliable, user-focused products.

I’m a Full Stack Developer who’s led cross-functional teams to deliver scalable platforms, combining Next.js, NestJS, and reliable data architecture. I build responsive web experiences with strong mobile accessibility and SEO performance, and I focus on system design, performance, and reliability through thoughtful APIs and deployment practices.

Recently, I’ve served as Technical Lead for ethical and simplified marketplace products—building multi-stage ingestion pipelines with Redis scaling, integrating Stripe payments, and implementing role-based access control. I’ve also worked on Web3 and AI-assisted initiatives, including linking investor contributions to on-chain smart contracts written in Aiken and designing architecture across Next.js, NestJS, and Python AI services.
