📅 Present
I am a 26 years old from Poland who loves technology, coding, architecture and volleyball!
Hey, I'm Nikita! I'm a Senior Full Stack Developer who works end to end — TypeScript / React on the front, Golang on the back. Day to day that means Next.js, TanStack Query and React Hook Form on one side, and Go services talking over gRPC and Kafka on the other, with PostgreSQL, DynamoDB, MongoDB and Redis behind them.
I also ship and run what I build: Docker and Kubernetes on AWS (SNS, SQS, DynamoDB, EC2, ELB), infrastructure as code with Terraform, and production monitoring through Grafana and Kibana. I care about tests that actually catch things — Cypress E2E, visual regression, and CI pipelines that stay fast.
Currently leading frontend development for a fintech startup, working directly with business and stakeholders, mentoring engineers, running code reviews, and staying hands-on with code. I enjoy taking complex problems (3rd party integrations, event-driven data pipelines, performance bottlenecks) and turning them into predictable, scalable solutions.
