Dmitrii Serebrov

First engineering hire; built the platform from the first commit to production use by enterprise customers in banking, healthcare, and investment, through a funding round from Astana Hub Ventures. Led a team of 10 engineers; own product direction since August 2025.

- Owned the end-to-end payment flow, processing 500K+ daily transactions: cut purchase-blocking failures from 1,000+/day (~30 of them P0/P1) to near-zero criticals — 1-2 P0s/week by instrumenting the funnel, isolating failure points from logs and metrics, and shipping fixes validated through A/B experiments - Ran conversion experiments on the same flow, increasing checkout conversion 18% and reducing cart abandonment 27% - Maintained versioning of shared component libraries used by multiple product teams

- Joined as 5th engineer; architected the frontend for a platform serving events with 15,000 concurrent users, winning Amazon as an anchor client - Reduced bug reports by 65% by introducing architecture standards and design patterns across the codebase - Led migration to micro-frontend architecture with zero production disruption; built monorepo, UI kit, theming, i18n, and test infrastructure

At this company, I tried my hand as the lead of the front-end team for the first time. By the end, my team created and maintained 2 successful projects for two big Russian banks. Achievements: - Gained experience creating apps from scratch for production - Got to know what the real responsibilities are - My company earned a lot from the projects I was involved in - Delivered 2 big apps for our clients - Provided various project assessments
