What I'm looking for

I’m looking for a product-minded engineering role where I can own complex frontend areas, modernize UI systems, and deliver integrations that improve real business workflows—while mentoring teams and shipping with strong React/TypeScript practices.

I’m a Senior Frontend Engineer with 12+ years in IT, specializing in React and TypeScript since 2018. I’ve built a reputation for owning complex product areas end-to-end—from architecture and delivery to measurable outcomes.

At ApprovalMax, I architected and led the first payment provider integration (Airwallex), enabling in-product bill payments for thousands of users. I also took full ownership of the Stand-alone Bills module, defining its architecture and simplifying workflows for non-integrated accounting systems.

I’m product-minded and treat technology as a tool for solving real problems. I initiated a modernization of core layout components using Storybook to standardize the UI and accelerate feature delivery for 3+ engineering teams.

I bring full-stack capability when it matters—solo-building a complete race management and telemetry system with React, Node.js, WebSocket, and ESP32 integration. I also invest in long-term growth through topics like web security (OWASP Top 10), system design, and algorithm practice.
