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
