Summary
👤
Senior🎓
Top SchoolNickolai Rumiantsev is a Senior Software Engineer with six years of experience building full-stack, high-impact platforms that tie engineering excellence directly to business outcomes. He designs resilient backend services (Node.js, PostgreSQL, MongoDB) and user-centric frontends (TypeScript, React), and has a proven track record replacing brittle Excel workflows and manual processes with scalable micro-frontend and ERP solutions. At Yandex he shipped assortment, logistics, and promo modules that reduced SKU errors and unlocked measurable GMV improvements, and previously rebuilt a core code-interview engine to Tier B reliability used for 100% of a major tech company's assessments. Nickolai also led integrations that brought ~80% of internal services into unified workspaces and mentored and interviewed dozens of engineers to grow strong teams. He enjoys tackling deep technical challenges—CRDT-based real-time features, accessible interfaces, and scalable architectures—and often prefers pragmatic, product-focused engineering over theoretical perfection. Based in Russia with a master’s in engineering, he blends hands-on delivery with a knack for translating complex domain needs into reliable, maintainable systems.
