Profile

Writing code since 2021, I've shipped products end-to-end across multiple verticals — APIs, backend logic, databases, and the automation around them. I think at the architecture level first: understand the constraint, weigh the tradeoffs, then execute. Today my focus is the data side of engineering: Python for data work, cloud infrastructure on AWS, and AI-powered workflows.

Skills

Languages: Python, Java, SQL, TypeScript, C#

Backend & data: REST APIs, FastAPI, Node.js, PostgreSQL, data pipelines, n8n, Supabase

Cloud & DevOps: AWS, Azure, Docker, Kubernetes, CI/CD (GitHub, Azure DevOps), Git
