What I'm looking for

I seek a role building scalable, cloud-native web platforms where I can drive performance improvements, reliable automation, and deployable ML/document-processing features in collaborative teams.

I am a senior full-stack engineer with strong experience building scalable web applications, ETL pipelines, and cloud-native services using Python, JavaScript/TypeScript, Django, FastAPI, React, and AWS. I have led implementations that reduced latency dramatically, replaced batch systems with real-time triggers, and delivered RAG-based document search proofs-of-concept for private financial data.

I bring a results-oriented approach demonstrated by measurable improvements: search latency cut from 8–9s to under 1s, downstream integration complexity reduced by 80%, and partner logistics trips reduced by 25%. I hold an AWS Certified Associate Developer credential and consistently apply automated, CI/CD-driven practices to deliver reliable, maintainable systems.
