What I'm looking for

I’m looking for a backend role where I can build scalable .NET APIs and middleware, own integration reliability, and collaborate with cross-functional teams in Agile/Scrum while continuously improving performance, fault tolerance, and developer-friendly documentation.

I’m a backend developer focused on building reliable, scalable APIs and middleware that connect enterprise systems end to end. I design and implement RESTful services, background processing flows, and fault-tolerant integration patterns to keep data consistent under real-world load.

In my current role, I’ve delivered backend services for HR and finance workflows by integrating external platforms with SAP through API middleware. I developed and maintained services that manage driver contract, timesheet, shift, overtime, and time-off data, and I built a journaling service to record and manage transactions from multiple payment gateway platforms.

Earlier, I built .NET Core RESTful APIs for real-time banking integrations and optimized backend logic and SQL Server queries to improve performance and stability. I also develop across the full stack when needed—leveraging JavaScript, Laravel, and responsive UI tooling—and I work closely with business and QA teams using Agile/Scrum to ship iteratively with clear API documentation and strong validation.
