As a Lead Software Engineer at Thoughtfocus, I develop web applications using the MERN and MEAN stack, leveraging my 6+ years of expertise in MongoDB, Express.js, React/Angular, Node.js, JavaScript, and PostgreSQL/NoSQL databases. I write clean, efficient, and maintainable code, ensuring data security and integrity, and optimal performance of the front-end and back-end systems. I have delivered cutting-edge solutions to meet client requirements, such as managing and optimizing EC2 instances within AWS infrastructure, implementing and maintaining S3 storage solutions, integrating and consuming RESTful APIs, and testing and debugging RESTful APIs using Postman test scripts. I communicate effectively with different teams, understand their needs, and provide support and troubleshooting for web applications. I also participate in code reviews and maintain code quality. I am passionate about learning new technologies and improving my skills as a full-stack developer.
