Full-Stack DeveloperAdditional professional experience: Electrical Engineering, Cybersecurity, Microsoft 365 AdministrationFull-stack developer with an engineer's eye for how systems fit together.
I build web applications and internal tools across the full stack, from interfaces and APIs to data, testing, infrastructure, and deployment.
- Across the stack
- Complete application deliveryFrontend, backend, APIs, data, testing, and deployment.
- Built for daily use
- Designed around real tasksInterfaces account for handoffs, exceptions, and repeated work.
- Engineering mindset
- Decisions with contextDependencies, failure modes, security, and maintainability considered from the start.
