What I'm looking for

I’m looking for a senior role where I can own frontend architecture, lead high-impact deliveries, and build high-performance React/Next.js products—including real-time and Web3 integrations—while mentoring engineers and partnering closely with product, backend, and DevOps teams.

I’m a Senior Frontend Engineer with 7+ years of experience building scalable SaaS, Web3, and enterprise applications. I specialize in React, TypeScript, Next.js, and frontend architecture, with strong backend expertise in Node.js and PostgreSQL.

I’ve led frontend development for large-scale web applications, building complex analytics and administration dashboards, and designing scalable, reusable component systems. I deliver high-performance real-time systems, Web3 and blockchain integrations, and I’ve helped scale products to 25,000+ daily active users.

I also bring technical leadership through code reviews, developer mentoring, and establishing frontend engineering standards and best practices. From architecting React/TypeScript platforms to improving performance and usability across high-traffic products, I focus on building reliable experiences teams can scale.
