About Anton

I help companies design and deliver scalable, high-load systems — from architecture to production.

What I bring
  • 15+ years in backend development (Java)
  • Hands-on Solution Architect / Tech Lead — I design systems and actively contribute to development
  • Experience as CTO — I focus on building solutions that meet business needs without over-engineering
  • Strong background in high-load and distributed systems
  • Strong background in complex integrations and data processing pipelines

What I typically do
  • Design scalable system architectures
  • Build and improve backend services and APIs
  • Fix performance issues and bottlenecks
  • Lead development teams and drive delivery
  • Integrate third-party systems and services
  • Work with complex business logic (financial flows, scoring, reconciliation)
Typical projects
  • Fintech platforms (payments, lending, banking)
  • High-load backend systems
  • Data processing and integration platforms
  • System refactoring and stabilization
How I work
I quickly get into existing systems, identify bottlenecks, and start delivering value within the first weeks — whether it’s building new features, fixing performance issues, or leading development.

I focus on practical solutions that solve business problems, avoiding unnecessary complexity and over-engineering.
