What I'm looking for

I seek a role applying secure-by-design full-stack engineering within collaborative SCRUM teams, focusing on scalable, user-centered systems and continuous professional growth.

I am a Full-Stack Developer and Cyberdefense student who combines secure architecture with functional, user-centric interfaces to build production-ready web applications. I prioritize engineering practices that harden applications while keeping experiences intuitive and performant.

My work spans fintech, e‑commerce, academic management, and AI processing, delivering modular backends and optimized frontends using Python (FastAPI, Django), Node.js, React, TypeScript, and Docker. Notable projects include a hexagonal-architecture mobile-first fintech prototype and several end-to-end systems that emphasize data integrity and transactional security.

I bring rigorous DevSecOps practices, a collaborative SCRUM approach, and continuous personal development through a public portfolio of projects. I seek roles where I can apply secure-by-design principles across the stack and contribute to resilient, user-friendly software.
