What I'm looking for

I'm looking to build reliable customer-facing products, solve complex production issues, and collaborate closely with product, engineering, and QA teams.

At LANACO, I build and maintain customer-facing e-commerce applications in React and Flutter, investigating production issues across frontend, API-driven, checkout, and transaction workflows. I work closely with engineering, product, and QA through implementation, code review, testing, and production verification.

I've also supported GrowFlow's large React application by resolving customer-impacting bugs and improving stalled transaction reliability with timeout and recoverable error handling. Previously, I built logistics, renovation-management, marketplace, IoT visualization, and WordPress products using React, TypeScript, Next.js, Angular, Three.js, Firebase, and REST APIs.
