2026 Portfolio

Java Software Engineer

Building backend systems with calm architecture and product-first AI.

I design API-first systems, optimize backend performance, and translate ML ideas into products people can actually use. My recent work spans Spring Boot services, deep learning pipelines for geospatial analysis, and GenAI-backed support workflows.
