About
Engineer first, lead by example.
I'm a software engineer and tech lead in Baku, Azerbaijan. Over the past seven years I've worked across the full stack, from the React front end to the APIs, payments, and infrastructure behind it.
I've led front-end delivery for several products at once, owned architecture through to production, and now run the CI/CD and cloud infrastructure that ships software at City Finance. I care about keeping codebases maintainable after launch and helping the engineers around me get better.
