I'm Andrejs Eisaks, a Senior Software Engineer with 10+ years of experience building backend platforms, distributed systems, and data-intensive workflows in Swiss and US startup environments. I have a strong track record modernizing legacy systems, designing pricing, payout, and identity workflows, and delivering asynchronous processing solutions that scale. I’m comfortable owning end-to-end delivery—from architecture to production operations—focusing on correctness, maintainability, observability, and pragmatic delivery. My approach centers on building comfortable, end-to-end owning systems and teams. I’ve led cross-functional efforts across backend, infrastructure, and DevOps, shipping strategic features on time while preserving compatibility and reliability. I thrive in high-ambiguity, fast-paced settings and enjoy mentoring engineers to raise the bar on quality and delivery speed.
