About

Practical engineering, clean delivery, and just enough frontend drama.

I studied Software Development & Network Engineering at Sheridan College and have hands-on experience across enterprise services, cloud data workflows, and full-stack product delivery.

My strongest work sits where backend reliability meets product experience: designing APIs, shaping data models, improving test suites, debugging production issues, and turning technical requirements into interfaces people can actually use.

Backend depth

Java, Spring Boot, REST APIs, SQL, data modelling, debugging, and service design.

Frontend feel

React, TypeScript, responsive UI, interaction polish, and accessible flows.

Selected Work

Projects with real product shape.

Current full-stack apps, AI tooling, production-minded workflows, and automation projects that show APIs, data, UX, testing, and delivery.
