I’m a senior full-stack developer with 10+ years of hands-on experience delivering end-to-end products across mobile and web—especially React Native (Expo) apps backed by REST APIs and PostgreSQL data models. I’ve taken features from well-defined scope through secure authentication/authorization, performance tuning, third-party integrations (including payment gateways and external financial data feeds), and reliable production deployments. I build systems with strong engineering practices: test-driven development, observable and recorded event workflows, and secure, role- and location-scoped access control. I also set up containerized services and CI/CD pipelines (Docker on AWS via GitHub Actions), document technical decisions, and mentor small teams to ship quickly without sacrificing quality—while ensuring smooth release management with version-gated updates across app stores and back-end services.…I’m a senior full-stack developer with 10+ years of hands-on experience delivering end-to-end products across mobile and web—especially React Native (Expo) apps backed by REST APIs and PostgreSQL data models.
