About me
I am a Senior Software Engineer specializing in Python and Generative AI, with 10 years of experience in software development and a background in Quality Assurance engineering. I focus on designing and delivering proof-of-concepts (POCs) that leverage Large Language Models (LLMs) and AI-driven agents to enable automation, optimization, and domain-specific analysis.
I am proficient in backend frameworks such as Django and FastAPI, and in modern AI ecosystems including LangChain, LangGraph, MCP servers, and agent architectures, plus whatever is popular when you read this, as I really try to stay up to date with emerging AI technologies to ensure solutions are built on relevant, state-of-the-art tools and best practices. Recently, I have been working extensively with Generative AI as a key developer while actively leading technical activities within and outside multiple POC projects.
