Summary
Oleksii Avdieiev is a Lead Software Engineer with 7 years of experience building high-throughput, cost-efficient systems and currently driving fintech engineering at Green Dot. He’s skilled in backend architecture, cloud-native operations, Kubernetes cost optimization, and payment integrations like Stripe, with hands-on experience migrating services and squeezing performance at scale (handling 80M+ reports/year). A founding engineer at Lemmi and a multi-role veteran of EPAM, he blends startup agility with enterprise discipline and takes ownership across the stack. Actively exploring AI, LLMs, and intelligent agents, he applies machine intelligence to developer tooling and debugging workflows. Outside engineering, he brings a strategist’s mindset—honed by competitive chess and ballroom dancing—to design elegant, maintainable APIs and systems. Based in Connecticut with a master’s in Computer Software Engineering, he’s as comfortable iterating on production code as he is explaining how he made Windows Authentication work on Linux.
