I’m Aman Kumar, a Software Engineer with 3 years of experience building scalable, secure, and high-performance applications. My core expertise lies in Java, Spring Boot, Node.js, and React, with strong proficiency in REST APIs, microservices, SQL/NoSQL databases, and cloud platforms like AWS and Azure.

Currently, at Deloitte, I work on developing production-grade APIs, optimizing system performance under high-concurrency workloads, and implementing secure authentication and caching pipelines. I’ve also enhanced system observability and deployment consistency using Docker, CI/CD pipelines, and ELK stack monitoring, significantly improving reliability and reducing release times.

Beyond my professional work, I’ve built projects that reflect my curiosity and problem-solving mindset — from an AI-powered algorithm visualizer to a full-stack expense tracker with real-time analytics. These experiences have deepened my skills in both backend architecture and frontend performance optimization, while sharpening my product thinking.

I thrive in collaborative, fast-paced environments, take ownership of delivering high-quality code, and continuously push myself to learn and adapt. My immediate goal is to grow as a Software Development Engineer, tackling complex engineering challenges and contributing to impactful products. Long term, I aim to lead and mentor teams while driving innovation in scalable systems.

I'm available for work, get in touch.
