About Me

Hi, Iā€™m Chandhiran S, a Full-Stack Developer and Data & Cloud Specialist with expertise in building scalable, secure, and high-performance solutions. I bring strong skills in frontend (HTML, CSS, JavaScript, React.js, TailwindCSS) and backend (Java, Spring Boot, Python, FastAPI, Microservices, Hibernate).

On the data side, I have hands-on experience in SQL databases (MySQL, PostgreSQL, Oracle), database architecture, big data handling, and reporting with tools like Metabase and Apache Superset. I love turning raw data into valuable business insights.

Iā€™m also skilled in cloud technologies with strong experience in AWS deployment and server management, ensuring applications are robust, scalable, and cost-effective. My mission is to deliver end-to-end solutions that combine clean design, solid backend logic, and intelligent data flow šŸš€
