Full Stack Developer | Backend Specialist

Bio

Sushant Kumar
Online

Hello! I'm Sushant Kumar, a Software Engineer II with 4+ years of experience building enterprise-scale applications in backend development, microservices architecture, and cloud infrastructure.

Currently at Equifax, I work with Google Cloud Platform, developing customer onboarding automation, building internal tools with Angular and TypeScript, and creating data pipelines using Apache Beam and Dataflow. I also developed a custom Jenkins plugin to streamline complex build configurations across teams.

Previously at Suntec Business Solutions, I contributed to the Xelerate platform - an enterprise revenue management system serving global banking and financial institutions. I worked on optimizing API performance with Spring WebFlux and Redis, building real-time data pipelines with Kafka, implementing authentication systems with OAuth2 and SAML, and developing a custom DSL using ANTLR for product configuration workflows.

I'm passionate about clean code, distributed systems, and solving complex problems. With a 6-star rating on HackerRank and 278+ problems solved on LeetCode, I continuously sharpen my algorithmic skills. I thrive in Agile environments, believe in writing maintainable code, and enjoy tackling challenges that drive real business value.

When I'm not coding, you'll find me exploring new technologies, participating in competitive programming on platforms like CodeChef and LeetCode, or contributing to technical solutions that make a difference. I'm always eager to learn, grow, and take on new challenges in software engineering.
