About Me

Backend Software Engineer focused on applied AI, software architecture, internal systems, automation, and data. I build platforms with Python, FastAPI, Node.js, TypeScript, SQL, and cloud infrastructure to turn real operations into reliable, observable, and evolvable software.

My work combines multi-agent RAG platforms, AI assistants, product backends, automation, data pipelines, and internal systems. I design AI solutions as part of the software itself: with retrievable context, controlled tools, memory, fallback behavior, permissions, logs, and traceability.

I also work with backend architecture, queues, caching, tests, CI/CD, observability, data security, and integrations when they belong to a larger system. The goal is to reduce manual work, clarify operational flows, and keep systems easy to evolve in real usage.
