About

Senior Go Backend / Platform Engineer & Feature Team Lead with 5+ years of experience building high-load, distributed, event-driven backend systems across eCommerce, EdTech, and geospatial products.

I turn complex backend domains into scalable, maintainable platforms with predictable delivery and measurable impact — from API/domain design to performance, reliability, observability, and cross-team delivery.

Impact & Leadership

Scale: At MTS, I develop Product Offering / Product Strategy — core capabilities of a high-load eCommerce platform serving 30M+ users and acting as a key entry point into the product ecosystem.
Performance: Reduced latency by 30% and increased throughput by 25% in critical offer-assembly flows via caching, batching, pre-aggregation, and fewer inter-service calls.
API & Distributed Systems: Delivered 15+ GraphQL/API scenarios for 25+ internal clients without breaking changes; eliminated GraphQL N+1 bottlenecks, reducing downstream calls from 22 to 3.
Reliability: Experience with systems operating under 99.95% SLA requirements; reduced average incident diagnosis from 60 to 15 minutes through enriched error context, structured logging, and failure classification.
Engineering Quality: Prioritized 20+ tech-debt initiatives, introduced Rich Domain Model / DDD / DOMA, and conducted 200+ code reviews; production defects, including regressions, decreased by 35%.
Leadership: Feature Team Lead in one of 5 feature teams within a 40+ person platform stream, coordinating a 7-person team (5 Backend + 2 QA Automation): planning, decomposition, backlog prioritization, cross-team alignment.

Earlier, I built EdTech services used by tens of thousands across 20+ educational institutions and geospatial services supporting 100k+ geo-tagged photos/videos.

Mentoring & Teaching

Go Backend Mentor & technical content contributor at True Tech Talents (ex-MTS Teta); Teaching Assistant for Programming Fundamentals at Voronezh State University. I mentor engineers/interns, run code reviews and architecture discussions, and teach production-grade backend practices.

Selected Achievement

1st Place — Digital Breakthrough Hackathon, “Profi” Track

Issued by Digital Breakthrough Hackathon / Presidential Platform “Russia — Land of Opportunity” · Jun 2026

Won 1st place in the “Profi” track of the nationwide Digital Breakthrough Hackathon as part of Team KYSS — 550+ applicants nationwide, 16 Profi teams, 4 stages, 8 finalists, and Team KYSS finished #1.

For a real government-backed case considered for public-sector integration, we built Komandus — an AI project manager for team collaboration.

Komandus addresses a key gap: decisions appear in chats, voice messages, and meetings faster than teams can document them. It bridges conversation and the task board, turning communications into tasks, assignees, deadlines, summaries, reminders, risk signals, and analytics.

My role: Tech Lead / Technical Product Manager / Backend Go Developer.

I coordinated product and technical execution in the 5-person team, owning product and technical logic end to end — from messages, voice notes, and meeting recordings to AI processing, human confirmation, task creation, reminders, and analytics.

The key idea: connect 12 collaboration and project-management platforms into one AI-driven workflow: Telegram and MAX via bots; YouGile, Jira, YouTrack, and Yandex Tracker for task management; Bitrix24; and Zoom, Yandex Telemost, MTS Link, Microsoft Teams, and Kontur.Talk as sources of recordings, transcripts, and meeting context.

A key product mechanism was the “confidence traffic light”: AI determines whether a task can be created immediately, requires human confirmation, or needs clarification — preserving human control while automating routine PM work.

During the hackathon, we delivered an MVP with task extraction, voice and long-meeting transcription with speaker diarization, task confirmation, task cards, deadline reminders, dashboards, analytics, and an achievement system.

Result: 1st place among 8 Profi Track finalists.

Business value: less manual documentation, more transparent control, faster conversion of decisions into action items, and lower coordination overhead.
