What I'm looking for

I’m looking to own end-to-end technical direction, set architectural standards, and build scalable real-time products—where I can lead teams and connect backend design to great user experiences.

I’m a Senior Software Engineer with 13+ years of experience engineering high-scale, real-time systems. My trajectory ranges from co-building a mass email marketing SaaS from scratch to architecting cloud-native telemetry platforms and leading international engineering teams on-site in Vietnam.

I specialize in logistics, GPS tracking, and full-stack mobile ecosystems—bridging complex backend architectures with effortless user experiences. I focus on complete technical ownership, setting architectural standards, and stripping away complexity to build software that scales; most recently, I’ve architected and scaled high-throughput microservices using AWS Lambda, DynamoDB, and React for real-time fleet tracking.
