Nikolai Konstantinov

01 Summary

I'm a Lead Software Engineer and Engineering Manager with 5+ years of experience building large-scale consumer products, leading engineering teams, and working on the intersection of frontend architecture and AI-enabled software development.

At Sber, I lead a cross-platform team of Web, iOS, and Android engineers supporting 20+ products across SberOnline. My work covers software architecture, engineering standards, delivery, technical decision-making, developer experience, and collaboration with product and business teams.

Over the last few years, I've also been focused on AI for software engineering. I build AI agents, multi-agent systems, and MCP infrastructure that connect engineering tools, documentation, analytics, and development workflows. I'm particularly interested in how AI changes the software development lifecycle and the role of engineers within it.

I also regularly speak at engineering conferences including HolyJS, Stachka, MoscowCSS, and AI x Frontend on topics such as WebMCP, the Agentic Web, WebTransport, modern frontend architecture, and developer productivity.
