I’m a Software Developer with 4.6 years of hands-on experience specializing in the development of robust web APIs. I focus on crafting, refining, and optimizing RESTful APIs that deliver scalable, high-performing web solutions.

In my most recent role, I migrated 6 microservices from MongoDB to PostgreSQL, improving query performance, data consistency, and scalability. I also designed and implemented a custom migration application to automate transfers and reduce manual effort and error risk.

Across my previous experience, I architected RESTful services into domain-aligned microservices to enable independent deployability, and I engineered APIs supporting CRUD operations that increased data retrieval speed by 30%. I refined endpoint performance to cut average response times by 40% and improved database query performance through MongoDB aggregation-based sorting and MariaDB full-text search indexing.

I’m hands-on with testing and quality: I maintain unit tests across microservices (80%+ code coverage) using xUnit and Coverlet, and I validate stability through thorough testing. I’m currently seeking full-time opportunities in Software Engineering where I can build reliable backend services, strengthen API performance, and contribute to modern cloud-based deployments.
