Full lifecycle: requirements analysis and architecture design through implementation, maintenance, and growth of SaaS products - so founders can focus on the business, not the build. For the past years I ran a crowdsourced logo design platform: 75,000 B2B clients, 14M logos, 99.9% uptime against a 99.75% SLA. At peak I led a team of 7 while remaining the primary engineer on core systems. Experienced with large production codebases without regressions - test coverage, migrations, and zero-downtime deployment. I onboard quickly into unfamiliar teams and projects.

Built and led a team of up to 7 (developers, system administrators, designers), scaling it up and down by project phase - hiring and onboarding, work breakdown, code review, and release planning while staying hands-on in the codebase.
LogoTournament - a crowdsourced logo design platform: 75,000 B2B clients, 14M logos. Highlights:
- Sustained 99.9% uptime against a 99.75% SLA across 18 years of continuous development

- Payments: credit card and PayPal, multi-tier pricing, fraud protection - chargeback rate below 1%
- Performance: Redis session and page caching; Kafka for delayed processing, notifications, analytics; Rate Limiting
- Admin back-end with performance, statistics, and feedback tracking; sales history, tax, and payment-hold reporting
- UI: Production A/B testing for new features, vector drawing and annotation tools, React-based admin back-end.
