Alper Dal

Software Engineer

I'm Alper — an engineer with ~5 years of experience - mostly building data-heavy SaaS products. I've worked at early-stage startups and big teams like Cisco, mostly writing Ruby, Go, and Python — always poking at relational databases like PostgreSQL.

My path hasn't been perfectly linear: I've done backend and fullstack work, data engineering, and even dabbled in Web3. It's not a bug, it's a feature. I like figuring things out, wherever that leads.
