Rust · Backend Senior Mobile Indie Maker

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.
