During my 6-month internship, I worked extensively on backend development using Python, NodeJS, and ExpressJS to build scalable microservices. I also contributed to creating responsive and interactive front-end components using React, enhancing user experience through smooth integration with backend APIs. I gained valuable experience in SQL database management by designing and optimizing queries, and also implemented MongoDB for handling NoSQL data in full-stack applications. Additionally, I worked on AWS Cloud Services, managing infrastructure with EC2, S3, and Lambda, enabling cloud-based solutions. I automated testing, build, and deployment processes by setting up CI/CD pipelines, ensuring efficient and seamless project delivery.
