About Me

Bridging technical precision with user-centric design

Senior Engineer

I love building tools that empower people and simplify workflows.

Over the past 6 years, I've worked across high-growth startups, product agencies, and open-source ecosystems. My work sits at the intersection of robust backend infrastructure and pixel-perfect interactive frontends.

Whether architecting distributed microservices, fine-tuning state management, or designing intuitive micro-animations, I prioritize performance, maintainability, and accessibility at every layer.

✓
Architecture-First Mindset: Designing systems built for horizontal scale and high reliability.
✓
Obsession with Performance: Shaving milliseconds off load times and optimizing core web vitals.
✓
Collaborative Leadership: Mentoring teammates, facilitating design sprints, and driving team standards.
