Building scalable, high-traffic web applications with
cutting-edge front-end architecture and performance optimization.
01. About Me
I am a Staff Frontend Engineer and Technical Leader with over 12 years of experience orchestrating digital transformations for high-traffic, globally distributed web applications. My technical DNA is deeply rooted in JavaScript, TypeScript, and React.js, but my actual day-to-day involves looking beyond the code to align engineering strategy with core product goals.
Throughout my career—from building automated AI bots and modernizing architectures at Lightup Data, to leading a globally distributed team driving the Spend Management product at Rippling, and architecting e-commerce platforms for retail giants at QBurst—I focus on scalable front-end architecture, rigorous observability, and systemic performance optimization.
As a Staff Engineer, I thrive on multiplying the impact of those around me. Whether I am writing RFCs for complex migrations, mentoring engineers through technical fireside chats, or negotiating bandwidth for critical tech-debt elimination, I am fiercely committed to fostering an engineering culture of excellence, accessibility, and resilience.

Staff Frontend Engineer
Lightup Data
- Architectural Modernization: Audited the entire frontend codebase, identifying and documenting key scalability bottlenecks. Negotiated product bandwidth to execute a massive migration from React 16 to 18 and Redux to RTK Query, resulting in a 60% improvement in perceived performance via progressive rendering.
- Design System Leadership: Addressed severe UI inconsistencies by conceptualizing and leading the development of the "Energy 2.0" component library, ensuring a unified cross-app experience with minimal disruption to ongoing feature work.
- AI Integration: Built an OpenAI-powered "Genie Bot" using prompt engineering to automate complex manual configurations and unlock natural language API documentation search.
Senior Software Engineer
Rippling
- Team Leadership & Delivery: Led a distributed team of 5 engineers (US & India) on the Spend Management product. Spearheaded the 'Bill Pay' initiative from end to end, proactively managing design constraints and delivering strictly on schedule.
- Engineering Excellence: Authored critical RFCs for foundational shifts, including React Router V5 to V6 and integrating React Query. Implemented robust E2E test suites using Playwright (Web) and Detox (Mobile).
- Observability & Mentorship: Drove the "Zero Sentries" initiative by creating Retool dashboards to monitor product reliability. Fostered team growth by introducing bi-weekly technical fireside chats to discuss modern web advances.
Lead Engineer
QBurst Technologies
- Global E-Commerce: Led the frontend development (React SPA & Node.js BFF) for Uniqlo.com, a major Japanese retail giant, coordinating deployments across 8 geographical regions and optimizing Core Web Vitals to achieve sub-2-second page loads.
- Web3 & Blockchain: Architected and built React-based frontends for Ethereum dApps in collaboration with the blockchain giant ConsenSys.
- Full-Stack Versatility: Early career foundation in Python (Django) and backend systems, including the development of healthcare and scalable audio streaming apps deployed on AWS.
