Highly recommend! The work was excellent. We had to close the contract only because my side wasn't fully prepped to continue, but I will definitely rehire him once the project is ready to kick off again. Great experience overall.

.NET API Developer in Azure
Yasir did a great job jumping in and getting started right away. It was easy to talk with him about complex concepts. He reviewed the existing coding patterns, implemented new work following those patterns, and was open to feedback and suggestions during code reviews.
He successfully created integrations with Stripe and RevenueCat, demonstrating his ability to handle complex integrations. Additionally, he took the initiative to learn how to make updates to our Terraform automation and GitHub Actions pipelines so that he could assist further. Yasir worked with various Azure services, including Cosmos DB, SQL, and Azure Container Apps, effectively integrating these into the project. He received feedback on pull requests professionally and showed a genuine interest in implementing them correctly.
I would definitely hire him again.
