My Expertise
Areas where I excel and can help bring your ideas to life.
Mobile Development
Native Android and iOS (Kotlin, Swift) and cross-platform (Flutter, React Native) shipped to production.
Full Stack Development
End-to-end web in React and Node.js, plus the database layer that holds it together.
Cybersecurity
Bug hunting, penetration testing, and secure coding reviews on production systems.
DevOps & CI/CD
Pipelines, cloud infra, and the build/test/deploy loop that keeps releases boring.
