Sahil Verma — Software Engineer

Hi, I'm Sahil Verma! 👋 I'm a passionate Full Stack Developer with a solid foundation in Computer Science from IIT Goa. Over the years, I've honed my skills in back-end technologies like Spring Boot, Flask, and FastApi, as well as front-end tools like React. My expertise also includes working with databases such as PostgreSQL, MySQL, and MongoDB, along with containerization and deployment using Docker and AWS. At Paytm, I work on high-impact projects that process millions of SMS messages daily. I thrive in environments that demand high concurrency and real-time processing. One of my proudest achievements is developing a payload router service that handles 8000 TPS, ensuring seamless message routing for ML processing. Building and monitoring Grafana dashboards is part of my daily routine, providing critical insights to maintain system reliability. My technical toolkit includes: Back-End: Spring Boot, Flask, FastApi, Kafka, Microservices, Distributed System Front-End: React, React Router, AntD library, Axios Database: PostgreSQL, MySQL, MongoDB, Hibernate, SQLAlchemy Miscellaneous: AWS, Docker, Git, Horizontal & Vertical Scaling, Grafana, Jenkins Coding Languages: Java, Python, C++, Go, JavaScript, HTML, CSS Before Paytm, I interned at Siemens, where I improved user authentication and data analysis features for the QOR Tracker. This experience sharpened my problem-solving skills and taught me the importance of user-centric design. When I'm not coding, I love diving into new technologies and experimenting with microservices. Let's connect if you're into building scalable systems, solving tough tech problems, or just want to chat about the latest in tech!
