Who I Am

I'm a Software Engineer with 2.5+ years of experience building high-performance backend systems for financial and data-intensive platforms. My core strength is in backend engineering — scalable REST APIs, microservices architecture, and cloud deployments that handle real-world scale.

At LTIMindtree, I worked on a core banking platform for an Australian fintech client Credit Corp Group(CCG) — integrating payment APIs, building transaction workflows, and designing microservices that reduced security risks by 70% and improved query performance by 45%.

Completed my Master's in Data Science at UMBC (GPA 3.9/4.0), where I also built automation pipelines processing 34,000+ records on AWS. Actively seeking full-time backend SDE roles — eligible for OPT with STEM extension.
