My Focus Areas

Currently, I spend most of my time with the following areas.Connecting them to create a reliable systems.

Data engineering

I build reliable data workflows from various sources, from legacy databases to embedded sensors. I care about data quality and keeping data stream reliable from start to finish.

Full-stack development

I tried working across the full stack, from database design and backend logic to creating dashboard and web system. Thinking about the whole system, not just the screen.

Automation

I've previously automated workflows through scripts, scheduled syncs, and cron-migrations. Now, exploring AI-powered automation to create workflows and systems
