What I'm looking for

I’m looking for meaningful work where I can help shape a project from idea to delivery. I enjoy working through complex problems, bringing my own perspective and creativity, and finding practical solutions that people can rely on. I find it especially rewarding to see something I’ve helped build being used and making people’s lives a little easier.

Full-stack Typescript developer with 5+ years of professional experience and strong specialization in AI integrated systems and Web3. Built and shipped over 10 production applications across DeFi, fund administration, HR SaaS, loyalty platforms, e-commerce and education. Core expertise in Node.js, Next.js, and React, with hands-on experience in AI integrated processing systems and smart contract development. Comfortable owning a product end to end with minimal oversight, from architecture through to final user experience.
