Abdel-Rahman Sabry Alwtany Algharbeia
Available to hire
I am a backend-focused software engineer with around seven years building production-grade apps and business systems using Node.js (Express/FeathersJS) and TypeScript/JavaScript.
I have strong experience in billing, payments, and invoicing (Stripe, payment lifecycles, invoicing automation), RBAC, and SQL/NoSQL databases (PostgreSQL/MySQL/MongoDB). I’m comfortable with AWS deployments and building observable services (metrics, logging, tracing). I am also capable on the full stack with React/Next.js when needed.
