Summary
👤
SeniorAleksandr Kozlov is a Senior Software Engineer with 15+ years of experience building backend and cloud platforms that launch quickly and scale reliably across startups and large companies in Europe and the US. He repeatedly delivers MVPs in months and then architects for growth, combining Node.js/TypeScript/Java expertise with deep AWS know-how (Lambda, API Gateway, Fargate, RDS/DynamoDB) and pragmatic cost and observability practices. Aleksandr has led teams and cross-functional launches—from a Yandex AI-powered exam prep product that reached ~151k MAU and 90% market reach to a Cloud Management Platform built under HIPAA/GDPR constraints—and has a track record of turning interns into leads. He favors practical trade-offs, autonomous teams, and delivery-over-bureaucracy, and is now open to senior IC or tech lead roles while based in Portugal and working EU/US time zones. An engineer who measures early and iterates fast, he pairs product-focused speed with strong attention to security, HA/DR planning and long-term maintainability.
