I write backend software.

Java, Spring, SQL, cloud workflows, integrations, and applied AI.

I build APIs, web applications, data workflows, and services that run in production. Most of my work is Java/Spring and SQL, with cloud delivery and integration work around it.

Outside of work, I build practical AI tools with transcription, embeddings, vector search, and RAG.
