A bit about me
Associate Cloud Engineer
Google Cloud certified since 2021
I'm a full stack developer who builds scalable web applications. I work with React and Next.js on the frontend, Node.js and Python on the backend, and Google Cloud and Azure for infrastructure.
My recent projects lean towards GenAI: LLM and agentic apps in JavaScript and Python with Google ADK 2, a Gemini Enterprise flow, prompt engineering and AI based ticket analysis. I enjoy solving complex technical challenges in Agile teams using Scrum.
