What I'm looking for

I'm looking to build scalable, high-quality web systems where performance, accessibility, code quality, user experience, and business impact guide engineering decisions. I value collaboration across backgrounds and thoughtful work on performance-critical systems.

I improved web responsiveness for billions of Chrome and Edge users through Google Summer of Code 2025 with Chromium’s Chrome Speed Metrics team. I contributed C++ and Blink internals for more reliable Interaction to Next Paint measurement, diagnostics, and performance tooling.

At DXPR, I refactored the core builder and rich text editor into a plugin-based component system, built WCAG 2.x AA-compliant real-time editing workflows, and reduced required user actions by 50%. I also established unit testing in CI/CD, helping increase automated test coverage by 75%.

I build across front-end architecture, backend fundamentals, APIs, databases, and browser performance. I care about code quality, business impact, and user experience, making deliberate trade-offs between performance, maintainability, and product needs.
