What I'm looking for

I'm looking to build responsive web or cross-platform applications where I can contribute across React, Node.js, APIs, databases, UI/UX implementation, and software quality while continuing to grow as a full-stack developer.

I've built responsive web interfaces and RESTful APIs at Keylink Technologies PLC using React.js, Node.js, Express.js, and JWT authentication. I translate Figma prototypes into reusable components and support quality through unit testing, debugging, code reviews, and documentation.

Through MedConnect and JOnline, I've developed cross-platform telemedicine and cashless transportation solutions featuring Angular, Flutter, React.js, WebRTC, SignalR, SQL databases, and Ethiopian payment integrations including Telebirr and Chapa.
