I ship production systems that scale — backend & mobile.
7+ years building production software for fintech and high-scale consumer products — Open Wallet, Chingari (100M+ users), NeoFiscal, Megakassa. Today I write Rust backend services (auth, load balancers, ledgers) and lead delivery on senior mobile products. Open to remote roles in fintech and high-reliability systems — backend, mobile, or both.
// What I build
Rust Backend
productionAuth services with 2FA, HTTP load balancers, blockchain ledgers. Async-first, container-native, hardened for fintech-grade reliability.
Tokio · Axum · Hyper · Serde · Postgres · Redis · Docker
Senior Mobile
7+ yearsAndroid (Kotlin/Java) and Flutter. Architecture, performance, secure key storage, scaling to 100M+ users. Tech-leading teams of 1–15.
Kotlin · Compose · Coroutines · Hilt · Room · Flutter · Dart
// Now
- →Rust backend. Shipping prod-grade services on Tokio · Axum · Hyper. Postgres, Redis, Docker, CI/CD.
- →Tech Lead at Weelorum — leading 1–15 engineers, owning delivery of consumer mobile products at scale.
- →TradeTools.dev — my indie studio. 65 mobile calculators, iOS + Android, 7 trade categories.
- →Open to remote roles in US / EU. Rust backend, senior mobile, or hybrid roles in fintech and high-reliability systems.
// Selected projects
// Rust services
Production-grade auth with two-factor authentication. CI/CD on GitHub Actions, containerized deployment, hardened against common credential attacks.
High-performance HTTP load balancer on the Hyper framework. Async I/O, configurable backends, health checks.
Decentralized ledger implementing core blockchain primitives — cryptographic hashing, block validation, proof-of-work.
// Mobile at scale
Short-video social platform. Performance engineering on feed rendering and the video pipeline at scale. Cut startup latency 60%, APK size 40%; resolved 60+ critical defects in production.
Open-source crypto wallet. Multi-chain support, secure on-device key storage, encryption at rest, SSL/TLS pinning.
Kyrgyzstan's first solution integrating fiscal cash registers (KKM) with the State Tax Service for compliant real-time reporting. Architected from scratch and shipped to production.
