About Ujjwal Sotra

Software Engineer with 2+ years of experience in backend development, cloud-native systems, and DevOps-driven engineering, focused on building scalable, reliable, and high-performance applications.Currently at Amazon, I work on backend systems using Java and Spring Boot, where I optimized request routing and reduced latency by 30%. I have led and contributed to cloud-native service migrations to improve system reliability and scalability. I also designed and automated large-scale backfilling workflows using AWS Lambda, Step Functions, S3, and SQL, significantly reducing manual intervention while improving data accuracy and operational efficiency.Previously at GlobalLogic, I built data processing pipelines in Python, developed interactive dashboards, and collaborated closely with international clients to deliver product-focused, data-driven solutions. As a Software Development Engineering Intern at Samsung R&D, I researched AI/ML applications including CNNs and GANs for 2D-to-3D image conversion, contributing to innovation efforts and patent submissions.In addition to professional experience, I have built full-stack applications such as UExpenseTracker using the MERN stack, and I actively practice Data Structures and Algorithms to strengthen problem-solving and system design skills.I thrive in fast-paced, high-impact environments and enjoy working on complex engineering challenges. My core skill set includes Java, Spring Boot, AWS, REST APIs, Microservices, React, Python, SQL, and Distributed Systems.I am actively seeking Software Engineer / Backend Developer roles, including remote opportunities, where I can contribute to building resilient, scalable, and user-centric products.
