arseniy popovfrontend engineer

I build interfaces, systems, and product flows for complex software — from fintech to developer-heavy tools. I specialize in the React and Next.js ecosystem, including TypeScript, GraphQL APIs, and design systems.

stack

✦ react, typescript, product systems

✦ architecture, debugging, delivery

✦ fintech scale + game design intuition

✦ works across design and engineering

about

started with games → moved into fintech → now building systems.

I work between design and engineering.

my goal: reduce complexity without reducing power.

approach

  • — simplify before scaling
  • — remove unnecessary steps
  • — build systems, not pages
  • — think in flows, not screens

Fintech Frontend Engineer

I have hands-on fintech experience at Yandex, one of the largest internet companies in Russia and Eastern Europe. I built BNPL (buy-now-pay-later) product features used by millions of users across multiple markets.

My contributions helped double the Return on Assets metric through product and frontend improvements. I worked across platform integrations — web, mobile web, and partner ecosystem products — and participated in architecture decisions affecting frontend standards across the fintech platform.

Prior to Yandex, I built internal financial dashboards, admin panels, and B2B systems with high data density and strict reliability requirements.

  • — observability · CI/CD · multi-market
  • — high-scale · millions of users
