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.

Software Engineer with 12+ years of experience engineering high-scale, real-time systems. My trajectory spans from co-building a mass email marketing SaaS from scratch in a 3-person team, to architecting cloud-native telemetry platforms and leading international engineering teams on-site in Vietnam. Specializing in logistics, GPS tracking, and full-stack mobile ecosystems, I bridge complex backend architectures with effortless user experiences. My focus is simple: taking complete technical ownership, setting architectural standards, and stripping away complexity to build software that scales.
