Software engineer building backend systems,
LLM workflows & open-source tools

Open to relocation · EU / North America · Remote-friendly
Backend, DevOps, and AI/ML at PuppyDog.io. I built a mass personalization engine scaling from 10 to 10,000+ prospects per job, led a hybrid AWS→GCP migration that cut infrastructure cost by 36%, and lifted backend test coverage from 0 to ~75% — shifting releases from every two weeks to daily. I design around Node.js, Python, AWS, GCP, and agentic LLM workflows, and lean on Datadog for observability. Off the clock you’ll find me hiking Hiking, plotting chess moves Chess, or rewatching Game of Thrones Iron Throne. Strong CS foundation, bias for shipping — open to ambitious teams in Europe or North America.

What People Say

I had the privilege of working with Umair Jibran for over two years, and it is without a doubt that he is one of the most talented backend resources I've had the pleasure of collaborating with. Umair not only possesses exceptional technical skills but also carries himself with a remarkable level of professionalism, setting a clear standard for what a Professional Engineer should be.
