🙋🏼‍♀️ About Me

I’m Shreya Ranjitha, an Electronics and Computer Science undergrad at VIT Chennai. I'm passionate about building smart applications by blending hardware with software. This summer(2025), I was a Summer Research Intern at IIT Hyderabad under Dr. G. V. V. Sharma, working on microcontroller programming and system-level development. I'm also selected for the Samsung Prism Programme. I’ve worked on multiple real-world tech projects, ranging from hand gesture control to blind assistance systems, a novel approach in image processing for home intrusion detection systems.

I'm now looking to expand into Software Development internships where I can apply my logic-building, C/Java/Python programming, and system integration skills to solve meaningful problems.

🌐 Looking for: SDE Internships, especially in fast-moving product-based companies.
