At Interexy, I shipped Rowte.io's fintech MVP from no code to production in three months and owned its Go backend. I built a payout engine with idempotency middleware and a transactional outbox, and replaced spreadsheet reconciliation with a rerunnable job matching 40,000 enrollments against 38,000 payments in 45 seconds.
At Interexy, I also split NextStreet's backend between NestJS APIs and Go services, cutting core reporting query times by 60%. For Supplier Success Accelerator, I owned integration architecture and delivered five external integrations with no lost events at 10,000+ actions a day.
At OkVPN, I split the NestJS monolith into Go microservices communicating over gRPC and RabbitMQ, while keeping NestJS as the API layer. I owned API contracts and production deployments for the extracted services and built a referral payout service that grew subscriptions 12% in three months.
I built Gonteractive, a self-hosted AI tutor for learning Go, integrating the Anthropic API, OpenAI-compatible APIs, Claude Code, and Codex. I also built Uchetka, an open-source finance dashboard for tutors.
