What I'm looking for

I’m looking for a team where I can build reliable, scalable services—APIs and microservices—using clean architecture, strong testing, and modern cloud practices, and where I can keep improving performance, maintainability, and developer velocity.

I’m a Senior Software Engineer with 9+ years building scalable applications across backend and cloud platforms. I focus on delivering reliable systems through clean architecture, SOLID principles, and maintainable service design.

In my current role at AAA Auto Club Enterprises, I’ve built a high-volume backend platform using Python, FastAPI, and PostgreSQL, and improved processing performance by about 25% through asynchronous Celery and Redis workflows. I also applied modern Java and C# backend patterns (DDD, clean architecture, dependency injection), improving service maintainability and reducing deployment issues by about 20%.

Across my experience at AAA and T-Mobile, I’ve shipped REST and microservices-based systems with strong security and testing practices, including automated test suites that increased reliability and deployment confidence. I’ve also built CI/CD pipelines and infrastructure using GitHub Actions, Jenkins, Docker, Kubernetes, Terraform, and major cloud services like AWS and Azure.
