Nikita Kovalenko
Team lead / Flutter engineer · architecture & teams from scratch · AI-first processes
5+ years of cross-platform development (iOS, Android, Web, macOS), including solid fintech and crypto experience; these days I work across the full stack (mobile, Node.js/TypeScript backend, Next.js web). I design app architecture from scratch (DDD, Clean Architecture, feature-first) and set up the engineering process around it — Git flow, CI/CD, code review, testing to a 70–75% coverage bar. I build and lead small teams, coordinate project delivery, mentor developers, and set up AI engineering for teams — agent harnesses, skills, and multi-agent pipelines that take a task from ticket to reviewed PR — with AI output held to the same review bar. Fluent English (C2) and Spanish (C2).
