Summary
👤
SeniorRuslan Zapevalov is a Senior Software Engineer and founding engineer with six years of cross-stack experience building mobile (React Native), web, backend, and infrastructure for high‑traffic consumer and Web3 products. He excels at end‑to‑end ownership—turning ambiguous product ideas into production systems, shipping quickly, and optimizing for performance and scale. His work spans privacy‑first integrations like ZK, wallets, payment rails, and on‑device anonymous notification flows implemented via native bridges. Notable results include architecting Launchbreak and a multi‑tool AI agent platform that supported rapid traction and significant transaction volume. He’s pragmatic with stacks (Node/TypeScript, Bun, GraphQL, Postgres, WatermelonDB) and experienced operating infra on GCP/VPS while mentoring junior engineers. Based in Serbia, Ruslan combines startup founder mentality with deep engineering rigor and a knack for shrinking app startup times and sync complexity.
