Fractional CTO & Technical Leader | Building scalable systems and engineering teams
Former founder, current Engineering Manager, recovering fullstack developer who still enjoys debugging production at 3am.
I'm a hands-on technical leader with 12+ years building and scaling products across MarTech, AdTech, TravelTech, EdTech, FinTech, and E-commerce.
Current: Head of Engineering at Vacayou (traveltech) — leading migration from monolith to modular architecture
Past:
- Built tech department at Artics (one of Russia's leading digital marketing agencies, $80M+ revenue) from 2 engineers to 12
- Founded an edtech startup EasyCoders
- CTO experience in adtech/martech
I've architected systems at enterprise scale and bootstrapped MVPs on tight budgets. I know when to over-engineer and when to ship duct tape.
Languages & Frameworks:
- JavaScript/TypeScript (Node.js, React)
- C# / .NET Core
- SQL (PostgreSQL, MS SQL)
Architecture & Patterns:
- Clean Architecture
- Domain-Driven Design (DDD)
- Microservices & Modular Monoliths
- Event-Driven Architecture
ML/AI:
- Recommendation engines
- Bid optimization algorithms
- Multi-armed bandits for A/B testing
- Data pipelines at scale
DevOps & Cloud:
- AWS / Google Cloud / Azure
- CI/CD pipelines
- Infrastructure as Code
- Monitoring & observability
At Scale:
- Migrated legacy monolith to modular architecture (zero downtime, ongoing)
- Built AI-driven ad optimization systems (recommendation engines, bid optimization)
- Scaled engineering teams 6x while maintaining code quality and culture
- Designed data pipelines processing millions of events daily
From Scratch:
- MVPs that survived first contact with users and scaled to thousands
- Engineering hiring frameworks (from 2 to 30+ people)
- Technical architectures that grew from prototype to production
I help growth-stage startups (pre-seed to Series A+) scale their product and engineering teams without the chaos.
What I do:
- Architecture decisions that scale (but don't over-engineer)
- Build/scale engineering teams 3→10→30+ people
- Technical debt management and prioritization
- AI/ML integration for real business value
- Prepare for fundraising & technical due diligence
- Code reviews, mentoring, hands-on debugging when needed
Industries: MarTech, AdTech, TravelTech, EdTech, FinTech, E-commerce
Available for: Growth CTO & Scale CTO engagements (10-20 hrs/week)

"Perfect is the enemy of shipped. But shipped without architecture is the enemy of scale."
I believe in:
- Clean code that other humans can read
- Architecture that evolves, not rewrites
- Teams that own outcomes, not tasks
- Decisions documented in ADRs, not tribal knowledge
- Shipping fast, but not recklessly
