With 17+ years of professional experience, I specialize in building scalable Enterprise ecosystems for Fintech, MedTech, and E-commerce. My core expertise lies in transforming complex monolithic legacy applications into high-performance, autonomous micro-frontends and robust microservices.
Currently, I'm deeply focused on expanding my engineering horizon into cloud-native backend development with Go (Golang).
- backend-modular-monolith — High-performance Go backend service designed with a Modular Monolith architecture.
- Features: Decentralized Service Discovery (via lightweight NATS JetStream KV registry), split routing, dynamic Gateway reverse-proxy with SHA-256 routing cache, and strict generation-based versioning.
- environment — Network GitOps & DNS Infrastructure.
- Features: Automated
dnsmasq, WireGuard setup, and system components configuration on Debian/Ubuntu with safe Mozilla SOPS secret encryption.
- Features: Automated
- algoritms — Data Structures, Algorithms & Problem Solving.
- Features: Clean implementations in JavaScript/TypeScript focused on time/space complexity and algorithmic excellence.

- Promsvyazbank: Engineered the architecture for the Digital Ruble and SBP (Faster Payments System) using Micro-frontends, reducing time-to-market for new features by 40%.
- Grid Dynamics & Align Technology: Managed cross-functional MedTech teams delivering 3D-visualization and genomic analysis workflows; enforced strict Quality Gates (Sonar, 80%+ Jest coverage) reducing production defects by 25%.
- EPAM Systems (SPB & USA):
- EPAM SPB (2017–2019): Designed and built the frontend architecture for Genocity (a comprehensive genomic analysis platform for cancer treatment and DNA sequencing), successfully releasing it to production.
- EPAM USA (2019–2020): Based on successful Genocity release, relocated to the USA to work directly with Penske Truck Leasing. Architected a global Design System adopted across 5+ international projects and doubled legacy-to-Angular migration velocity.
- Magora Systems (2015–2017): Managed an engineering department of 15+ developers. Designed, architected, and delivered complex products from scratch, including Flexbord.com (an advanced SaaS sports organizing network and real-time scoreboard system), Bernsoffroad, and high-traffic booking widgets integrated with the YClients ecosystem.
- Vsemayki.ru (2014–2015): Head of Software Development (CTO). Successfully optimized infrastructure costs during the 2014 crisis, preserving the engineering team and architecting a distributed storage system (MooseFS + BitTorrent Sync) to launch a network of offline print-centers.
