What I'm looking for

I seek roles where I can lead cloud-native and AI-enabled engineering initiatives, drive automation-first testing and CI/CD improvements, and deliver operational cost savings at scale in collaborative, outcome-focused teams.

I am a Lead Staff Software Engineer with 12 years of experience architecting cloud-native systems, AI/LLM integrations, CI/CD pipelines, and large-scale test automation. I have led cross-functional teams to deliver measurable results — including $1.6M annual savings, dramatic defect and memory leakage reductions, and major performance and security upgrades across US store and distribution systems.

I design and implement end-to-end fulfillment, ETL, and pluggable AI frameworks using AWS, NodeJS, Laravel, and frontend frameworks, while standardizing coding practices and automating release workflows. I prioritize scalable architecture, automation-first testing, and operational efficiency to accelerate time-to-market and reduce maintenance overhead.
