Rujen Shakya · Kathmandu, Nepal · Open to new roles
Hi 👋EngineerI build mobile apps used by millions — and lead the teams that ship them. Flutter & Android · fintech, banking and edtech · Mobile & Web App Lead at Yirifi.ai.
Engineer first, lead always — eight years of shipping production mobile apps and running the delivery behind them.
Flutter and native Android apps built end-to-end: architecture, state management, network layers, CI/CD and store releases. Fintech-grade — payments, biometrics, offline modes.
Leading mobile teams while staying hands-on: mentoring, code review, sprint management, and turning CEO-level goals into shipped features as sole project manager.
ISO 27001 and SOC 2 from evidence preparation to successful certification — building delivery processes that are fast and audit-proof at the same time.
