Hello! I’m Shree Krishna Agrawal, a highly skilled Back-End Developer with over 8 years of hands-on experience in designing and delivering robust, scalable, and secure systems across a wide range of industries.
I bring deep expertise in PHP, JavaScript, and Node.js, along with extensive experience using modern frameworks such as Express.js, Laravel, Symfony, and Mocha. I specialize in building high-performance APIs, architecting microservices, and developing cloud-native and serverless solutions using tools like the Serverless Framework to support business growth and technical excellence.
I am well-versed in Agile methodologies and have strong capabilities in database architecture, RESTful service development, and automated testing. My development approach emphasizes writing clean, maintainable code and building systems that are efficient, scalable, and secure.
I thrive in collaborative environments, working closely with product managers, designers, and cross-functional engineering teams to drive innovation, optimize workflows, and deliver impactful solutions aligned with strategic objectives.
