About Me

Who Am I?

Hi I'm Sankar Sai Galla. a results-driven Full Stack Developer with over 4 years of experience specializing in full-stack development, backend engineering, quality analyst and Generative AI applications. I recently earned my Master’s degree in Computer Science from Texas Tech University, where I deepened my expertise in AI/ML systems and large-scale cloud architectures.

I bring strong knowledge of both high-level and low-level system design, enabling me to build scalable, secure, and modular applications that align with real-world business needs. My hands-on experience includes architecting RESTful APIs using Python (Flask, Django) and Java (Spring Boot), developing responsive UIs with React and Web Components, and designing robust data models with MySQL, PostgreSQL, and MongoDB.

I have worked extensively with OAuth 2.0 authentication, automated CI/CD pipelines using Jenkins and Docker, and deployed containerized microservices on AWS EC2 and Lambda. I consistently apply system design principles to ensure high availability, fault tolerance, and maintainability across services. Additionally, I focus on accessibility and performance, ensuring WCAG 2.2 compliance and delivering seamless user experiences.

I'm passionate about applying emerging technologies to solve real-world problems. I’ve built GenAI-powered chatbots, domain-adaptive machine learning models, and full-stack platforms deployed on AWS. Whether I’m integrating LLMs for intelligent user interaction, designing resilient cloud-native systems, or optimizing infrastructure with Docker and Kubernetes, my goal remains: to deliver high-impact, user-centric digital solutions.
