Nikita Kovalenko
Senior Flutter Engineer · architecture from scratch, building & leading the team · AI-first processes
5+ years of cross-platform development (iOS, Android, Web, macOS), including solid fintech and crypto experience. 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, mentor developers, and run an AI-first workflow (custom multi-agent pipelines), with AI output held to the same review bar. Fluent English (C2) and Spanish (C2).
