My hands-on experience spans RESTful and GraphQL APIs, React Native cross-platform mobile apps, cloud infrastructure (AWS/GCP), containerization and CI/CD pipelines.

I am committed to driving innovation, optimizing system performance, and delivering mission-critical systems that serve large user bases while continuously adopting modern development practices and mentoring the next generation of developers.
