What I'm looking for

I seek roles where I can lead backend architecture, integrate AI, mentor engineers, and drive scalable, high-throughput systems with strong cross-functional collaboration.

I am a senior backend engineer with six years modernizing accounting and F&B enterprise systems using AI-powered tools and solid engineering practices.

I write high-quality, maintainable code and have delivered 3,000+ contributions while architecting scalable customer-facing platforms that supported growth from seed to 10M+ users and handled 5B+ records.

I mentor and upskill engineers through code review, pairing, and technical ownership, improving delivery speed by 40%+ and fostering trust, transparency, and independence across teams.

My hands-on experience spans API design, data modeling, microservices, observability, and CI/CD; I prioritize pragmatic execution and long-term architecture to reduce technical debt and accelerate product outcomes.
