Senior Developer and Team Lead. Building reliable products in C#, Go and React since 2015, leading product teams, shipping with AI and solid CI/CD.
By the numbers
My name is Mark. I’m a Senior Developer and Team Lead — in commercial development since 2015. I own a task end to end: from design and architecture to production rollout and support.
Backend, depending on the task — C# / .NET, Go, Rust, Python (I write Telegram bots in it) and PHP (Laravel, Symfony). Frontend — React / TypeScript, on the PHP stack — Twig / Blade. Mobile — Flutter. I design APIs over REST and gRPC, and split systems into microservices where it actually pays off.
I use AI heavily and write my own MCP servers. I set up CI/CD (GitLab CI and GitHub Actions, dev/prod), containerize and automate releases. On services I close the full observability loop — metrics, logs, monitoring — and focus on fault tolerance and stability.
I write unit, functional and load tests, and work closely with QA. I take data security seriously: CVE auditing, protection against injections, encryption and regular backups (with age). I own authentication and authorization: SSO, OAuth 2.0 / OIDC, JWT, role-based models and Keycloak.
P.S. This site is my work too: design, code, containerization and deploy to my own VPS — I did all of it myself, from the first pixel to the production certificate.
