Summary
👤
SeniorDenis Ivanov is a seasoned Team Lead Fullstack and Staff Engineer with over a decade of hands-on experience building high-load, cost-efficient systems and end-to-end products. He specializes in turning legacy bottlenecks into scalable architectures—frequently migrating Node.js nodes to Go—and has designed distributed storage, SSO, and fintech modules from scratch. Denis blends technical depth (Go, TypeScript, React, PostgreSQL, Docker, K8s) with delivery discipline, having built CI/CD pipelines and led cross-functional teams from zero to high velocity. He’s proven in crisis-driven wins, architecting competitive tender solutions in days and establishing release and code-review cultures that reduce production risk. Less obvious: he pairs frontend data-visualization expertise (D3.js) with backend optimizations, enabling product teams to ship both performant APIs and insightful UIs.
