Engineering · Product · Leadership

Denis Bunchenko

I build web products and the systems and teams that make them durable.

I'm a senior frontend engineer focused on turning ambiguous product problems into clear, maintainable systems.

I work where engineering, product judgment, and team leadership meet; away from the screen, I'm a husband, father, LEGO builder, and cyclist.

A note on turning a quiet publishing site into a clearer record of projects, decisions, and the way I work.

An interactive exploration of request IDs, deadlines, and duplicate handling, with the boundaries that make a small simulation useful.

I'm always interested in thoughtful work, useful exchanges, and meeting people who care about how products get built.
