Software Engineer @ Blackhawk Network | Full Stack Development

About

Software Engineer with nearly 3 years of experience designing and building scalable backend systems, distributed microservices, and enterprise-grade full-stack applications. I specialize in Java, React, Spring Boot, AWS, cloud-native architectures and Java Script with hands-on experience delivering production systems that power payment platforms, authentication services, and large-scale business applications. Currently at Blackhawk Network, I build and enhance mission-critical services supporting global payment and gift card platforms. My work includes developing secure REST APIs, implementing OAuth/SSO authentication, designing scalable microservices, improving observability using Splunk and Kibana, optimizing application performance with Redis caching, and building reliable cloud-native solutions deployed on Kubernetes. Previously, I worked at Unisys, contributing to enterprise airline, where I developed backend services, implemented business-critical APIs, optimized database operations, and collaborated with cross-functional teams to deliver secure, high-performance applications. I began my professional journey at Hexaware Technologies, where I strengthened my foundation in Java, Spring Boot, and modern software engineering practices. I enjoy solving complex engineering challenges involving distributed systems, API design, system reliability, performance optimization, and cloud infrastructure. I believe in writing clean, maintainable code while building scalable solutions that create measurable business impact.
