About me

Hi, I’m Anton Gavrilov.

I’m a Senior Software Engineer and Team Lead with 4+ years of experience building and scaling high-performance backend systems, primarily in fintech and product-driven environments. I specialize in modernizing legacy platforms, designing microservices and event-driven architectures, and applying Domain-Driven Design and Clean Architecture to create systems that are reliable, maintainable, and easy to evolve.

My core expertise is in .NET (C#) backend development, working with PostgreSQL, SQL Server, MongoDB, and Redis, and operating cloud-native infrastructure using Docker, Kubernetes, and CI/CD pipelines. I also place strong emphasis on observability, implementing distributed tracing, logging, and monitoring with tools like OpenTelemetry, Prometheus, and Jaeger.

In addition to my .NET background, I’m actively interested in Go-based backend roles and enjoy working with Go for building high-performance, concurrent, and cloud-native services, especially in distributed and event-driven systems.

Beyond hands-on engineering, I enjoy technical leadership, mentoring developers, and driving architectural decisions that improve system performance and team productivity. I’m always interested in building thoughtful, well-designed systems and contributing to teams that value engineering excellence and continuous growth.

I created some own projects which you can find at my GitHub profile. For now, my main projects are:

  • Mobile application for finance control, that's named Profitocracy. It is created with .NET MAUI;
  • Web service, which is called ScienceArchive, for publishing science articles of independent scientists. It is written using C#, Angular and PostgreSQL. Also, I practiced using CI/CD with GitHub Actions there;
  • Desktop application for generating TOTP codes, called ChronOTP.
