About Sai Charan K.

With over nine years of experience in web application design, development, and maintenance, I have a proven track record in building scalable, responsive applications. My expertise spans across multi-tier architectures, particularly SaaS, and includes a deep understanding of both MEAN and MERN stacks. I bring robust skills in various SDLC methodologies (Agile, TDD, Waterfall) and am proficient with Node.js, Express, and microservices architecture. I have led projects utilizing ELK stacks for real-time data profiling and monitoring, managed complex Identity and Access Management systems using tools like AWS Cognito, KeyCloak, and Auth0, and built secure, dynamic applications that rely on JWT and OAuth2.0 for authentication. My cloud experience is extensive, especially with AWS services such as EC2, S3, VPC, and CloudFront, complemented by proficiency in Docker and Kubernetes for container orchestration.In my recent roles, I developed RESTful APIs and real-time applications that integrated seamlessly with Amazon Connect and used event-driven architectures for enhanced performance. My full-stack expertise includes advanced skills in front-end frameworks like React, Angular, and Vue.js, along with back-end orchestration with tools like RabbitMQ, Kafka, and various RDBMS including PostgreSQL and MongoDB. I am passionate about building user-centric applications and have consistently delivered high-quality solutions across industries, working collaboratively with cross-functional teams to ensure optimal outcomes. My technical toolkit also includes robust knowledge in Docker, Kubernetes, SQL, PL/SQL, and CI/CD pipelines, ensuring seamless deployment and scalability of applications in complex environments.
