About Me
I spent my childhood traveling the globe before finally settling in Oregon, USA, at 17. This journey, captured in these images, has enriched my perspective in countless ways. Since then, Oregon’s tranquil landscapes and vibrant culture have been a constant source of inspiration and serenity in my life.
Experience
I've been working as a full-stack developer for the past 4 years. Here's a timeline of my journey.

Full-stack Developer
- Search Architecture Optimization: Replaced an over-engineered Elasticsearch cluster with PostgreSQL Full-Text Search (GIN Indexing). Simplified infrastructure complexity while maintaining <60ms query latency for a 2,000+ item faceted search system.
- Fault-Tolerant Data Pipeline: Engineered a resilient upload system for 30GB+ video files over unstable networks. Wrapped AWS CLI in a Python subprocess with a custom Finite State Machine for retries, reducing failure rates from 40% to <2%.
- Distributed Hardware Synchronization: Designed a UDP multicast protocol in Node.js to synchronize 4K video playback across 6 independent networked devices with <100ms latency, eliminating the need for cloud-based coordination.
- Legacy System Modernization: Led the migration of a 191,000-line C++ codebase (Qt 5 to Qt 6) and parallelized the Jenkins build pipeline, reducing deployment time by 78% (90m → 20m).
- Performance Engineering: Optimized an interactive museum application to run at 60 FPS on hardware-constrained BrightSign players by implementing custom asset caching and removing expensive CSS filters from the render loop.
