About.

About me

Passionate technologist with ​10 years of professional experience as a software engineer, currently leading engineering teams and AI-driven product initiatives. I believe deeply in the principles behind solid software design, security, and engineering excellence — languages and frameworks fall into place once the fundamentals are strong. My focus today spans backend architecture, AI/LLM systems, and scalable platform engineering.

Building production systems with Python, Django, FastAPI, and modern LLM tooling — including RAG pipelines, vector databases, and agentic workflows. I also administer Linux infrastructure, lead Application Security efforts, and routinely tackle performance, deployment, and reliability challenges across the stack. Always exploring new frameworks, AI capabilities, and security research — focused more on functionality, performance, and robustness than on visual polish.
