Andreos Klering

Engineering Leader & Builder

I build products and teams from zero to scale. I've spent 20 years shipping software in fintech, SaaS, and payments— founding startups, scaling engineering orgs, and turning messy problems into working systems.

I move between hands-on building and engineering leadership. I care about speed, quality, and teams that actually ship. Currently leading Growth & Customer Experience engineering at Nexar.

Builder energy. Strong opinions, loosely held. Ships over slides.
