About

A senior backend engineer who thinks like a business analyst.

I started from applied mathematics and C++, then spent 15+ years delivering Ruby on Rails products before moving my main focus to Elixir and Phoenix. That mix gives me a practical view of architecture: fast enough for product work, disciplined enough for long-lived systems.

Before backend engineering became my main focus, I ran a business-automation practice, translating client processes into working systems for more than a hundred companies. That background still shapes how I work today: I start from the business problem, not the ticket, and let architecture follow from what the client actually needs, across enterprise workflows, data-heavy applications, and integration-heavy platforms.

Experience

Selected work history

Lead Elixir Engineer / Architect

Awaken Protocol

  • Designed and built a real-time, persistent MMO game server in Elixir, using OTP supervision trees so individual process crashes recover automatically without affecting other players or overall uptime.
  • Architected secure server-side script execution so players can run custom code while offline, each script isolated in its own lightweight BEAM process for per-script fault and memory isolation.
  • Built the public-facing Phoenix platform, a TypeScript/Electron desktop client, and a Prometheus/Grafana monitoring pipeline for the game server.

Ruby on Rails Engineer

Easy8 Software s.r.o.

  • Built and maintained core modules and plugins for WorkOps Platform, an enterprise work-management product used globally and developed as the next generation of Redmine.
  • Engineered a hybrid Ruby and C++ full-text search module, cutting queries that took several minutes down to under 1 second for 95% of requests across massive enterprise datasets.
  • Designed GraphQL API layers exposing enterprise platform data for internal and third-party integrations, and refactored SSO/SAML authorization to support new identity-provider integrations.
  • Contributed to an AI assistant subsystem using Python, Ruby on Rails, LangChain, and RAG workflows.

Backend Engineer / Contract Tech Lead

Evrone , Good Bit Labs, Smart-Story and others

  • Provided technical leadership and architecture across complex backend ecosystems for multiple development agencies and enterprise domains.
  • Integrated ERP/CRM modules, infrastructure tools, network equipment, and web platforms.
