Muhammad Taimoor

Software Engineer with 3+ years of hands-on experience building Amadeus GDS integrations from scratch on the Amadeus Enterprise plan, covering the full flight and hotel booking lifecycle — search & availability, fare re-pricing, ancillary services, PNR creation/booking, and ticket issuance. Also built a parallel integration with Mondee, a travel consolidator, delivering the same end-to-end booking lifecycle for another flight and hotel platform built from scratch. Strong RESTful API development background in Node.js, with experience designing and troubleshooting complex, high-stakes data exchange between backend systems and travel data providers.

Brings additional backend engineering depth — CI/CD pipeline ownership, PostgreSQL/MySQL database design, AWS cloud deployment, and secure API development practices — for building and scaling GDS-connected platforms end-to-end. Strong analytical and communication skills, comfortable bridging technical integration work with business and product requirements.

Note: hands-on GDS experience to date has been with Amadeus specifically (plus the Mondee consolidator); open to expanding into Sabre.
