Bello Dahood

I build and deploy full-stack applications independently, from database schema design through production release. My work combines React, TypeScript, Node.js, PostgreSQL, REST APIs, authentication, and role-based access control.

I built an issue tracking platform now serving active beta users, including JWT authentication, permission guards, protected routes, issue lifecycle APIs, Docker deployment, Sentry monitoring, and PostHog analytics.

I’ve also built a word analysis platform for writers and content evaluators, a real-time chat application using WebSocket connections, and a typed GraphQL API server that reduced unnecessary data transfer by approximately 50% compared with equivalent REST endpoints.

Alongside development, I’ve completed 30+ paid QA test cycles across gaming, fintech, health, and crypto payments. I bring that QA-informed approach to my own releases by validating failure modes, documenting systems clearly, and catching defects before deployment.
