About Me

Turning complex systems
into clean code

I'm a Software Engineer with over 2 years of experience building enterprise backend applications inside global banking environments. My work has ranged from designing scalable RESTful microservices to driving CI/CD modernization for critical financial reporting platforms.

At Synechron, I've worked directly on Citi Bank's Custody Data Store — optimizing SQL pipelines, improving code coverage past 80%, and collaborating with cross-functional teams to maintain platform reliability at scale.

I'm passionate about writing clean, testable code and continuously learning — holding four cloud certifications across AWS and Microsoft Azure. I'm an immediate joiner, actively looking for backend engineering roles where I can contribute and grow.
