Hi, I’m Ashen.

I build test automation frameworks from scratch, then do the harder part: get whole teams to actually adopt them. I own release quality and make the go/no-go call. Lately I build AI-powered test agents and evaluation suites for LLM features, and I mentor engineers making the jump into automation.

Through the lens

Photography is how I switch off. It’s the same instinct as testing, really: slow down, look closer, and notice the detail everyone else walks past.
