# Venkata Rohil Wardhan K > Software Engineer Location: United States, United States Profile: https://flows.cv/venkatarohilwardhank As a Software Engineer with a Master’s in Computer Science from SUNY Buffalo, I specialize in building scalable, secure, and high-performance applications across cloud-native environments. I bring hands-on experience developing full-stack solutions using Java, Spring Boot, and React, while integrating AWS services like Lambda, EC2, S3, and RDS to deliver efficient and resilient systems. I’ve worked extensively with modern DevOps tools including Docker, Kubernetes, and Jenkins to automate deployments and streamline development workflows. With a strong foundation in RESTful API development, microservices architecture, and database management using PostgreSQL and MongoDB, I focus on creating solutions that are both technically robust and user-centric. My professional journey includes roles at Verizon, Vanguard, TCS, and AntWorks, where I contributed to modernizing architectures, enhancing system security, and building responsive, data-driven applications. From leading agile teams to implementing CI/CD pipelines and migrating critical systems to the cloud, I’ve consistently worked at the intersection of innovation and execution. I thrive in collaborative, fast-paced environments and enjoy solving complex challenges that push the boundaries of what’s possible with technology. I'm always open to new opportunities where I can grow, contribute, and help drive meaningful impact. ## Work Experience ### Softare Development Engineer 2 @ Amazon Jan 2025 – Present | Seattle, WA ### Software Engineer @ Verizon Jan 2024 – Jan 2025 • Revamped full-stack applications by developing scalable solutions using Java, TypeScript, and React on Linux/Unix and Windows platforms.
