About
I'm a software and data engineer with around 12 years of experience building systems at the intersection of data, infrastructure, and product. My core strengths are Python, SQL, and data architecture — I enjoy turning messy problems into clean, working solutions.
Outside of work I spend time on personal projects: building tools I actually want to use, writing about what I learn, and exploring new ideas at the edges of software and AI.
Skills
- Python — data pipelines, APIs, automation
- SQL & data architecture — modeling, warehousing, query optimization
- Backend systems — FastAPI, REST APIs, cloud infrastructure
- Currently exploring — mobile PWAs, AI-assisted tooling
Now
- Building a personal expense tracker with Google Sheets sync
- Writing on this blog about engineering and side-project learnings
