Senior🎓
Top SchoolYevhen Mykhailenko is a Lead Software Engineer with nearly a decade of experience building and scaling high-load B2B and B2C platforms across payments, gaming, and SaaS. He combines strong full‑stack JavaScript/TypeScript expertise (Node.js, Nest.js, React) with practical backend skills—API design, SQL optimization, fraud detection, and CI/CD—that have reduced DB load, cut developer intervention, and increased sales efficiency in past roles. Yevhen has driven integrations with numerous third‑party services (messaging and payments), launched back‑office tooling that empowered non‑engineering teams, and delivered revenue-adding third-party APIs. Based in Kyiv and recently leading engineering at Voya Financial after senior roles at PayPal and product-focused startups, he pairs hands‑on coding with cross-functional leadership. Colleagues value his pragmatic automation mindset—he routinely turns operational pain points into measurable business outcomes.
