About Hema C

Driven by my passion for computers and its Applications, I decided to embark my professional journey as a java developer. With my innate-inquisitee nature, I have always been a coding geek; Thus took a full-fledged leap into Core technologies like JSE, JDBC, EJB as part of my professional endeavors. So far, I have Java, Spring Framework and related technologies, MongoDB, Oracle, MySQL under my belt and hands-on experience on various tools like Git/ GitHub I had introduced few innovative applications to the market and been a part of one of the sophisticated technologies. Keeping up the curiosity, I am currently obsessed and enthusiastically grabbing onto other programming languages, frameworks or industry applications.I often see myself with an explorative attitude as I enjoy meeting new people and learning new technologies. Reach out if you want to talk to me about emerging tech or about some interesting innovative applications that you have developed. I am always looking forward to an insightful conversation.
