01 // Background

About Me & Engineering Philosophy

I am a Software Engineer with 4 years of experience across Google and Amazon, specializing in building high-availability backend infrastructure, distributed scaling, and building production AI solutions.

Throughout my tenure in Big Tech, I have consistently navigated high ambiguity to deliver massive scale. At Amazon, I led technical execution for country-wide product releases, re-architected services to slash infrastructure costs by 75%, and contributed to scaling customer volume by 20x.

At Google, I architect mission-critical infrastructure that handles legal consents, automated translation review workflows, and coordinated high-volume user campaigns across the globe.

I am deeply passionate about applied Artificial Intelligence & Agentic Automation. In my daily engineering work, I actively build custom AI agents, orchestrate complex LLM workflows, and automate repetitive tasks—from code intelligence and regression analysis to operational tooling. I continuously master new AI frameworks to drive efficiency and build intelligent, resilient systems.
