Hello!! I'm Rajanya.

I am a

A techie with a traveler’s heart and a journal always within reach. I find joy in writing my thoughts, exploring new places, and meeting people from all walks of life. Whether I’m debugging code or strolling through a new city, I’m always chasing stories — in tech, in people, and in life.


What I Do

I am a Computer Science Graduate Student at The Ohio State University, building on my experience as a software developer and growing into the world of data science and impact-driven innovation. I believe that technology isn’t just about what we build — it’s about who we build for.

Before grad school, I spent nearly three years in the software industry (IBM ISL, Merative), where I worked across backend systems, cloud platforms, and cross-functional teams. I built scalable solutions using Java, SQL, Docker, and cloud technologies, always with an eye on usability and real-world impact.

Now, I’m expanding my focus into data analysis and research. I’m working on a research project with The American Heart Association under The Ohio State University Wexner Medical Center, diving into real-world healthcare data to understand how social factors affect heart failure outcomes. From cleaning and preparing messy datasets to building predictive models and identifying key mediators, I’ve seen firsthand how data can uncover hidden patterns and drive impactful insights in healthcare.

📚 What drives me

  • Solving real-world problems that have human impact
  • Turning messy data into meaningful insights
  • Staying curious — about people, places, and the stories data can tell

🧠 Core Strengths

  • Hardworking and committed to excellence
  • Quick to learn new tools and technologies
  • Punctual, organized, and reliable
  • Excellent team communication and collaboration

🎯 My long-term goal is to apply my skills in areas that truly matter — where tech can improve lives at scale. I'm looking to join a team that values innovation, purpose-driven work, and continuous growth.

🤝 If you're hiring or know of a team looking for someone motivated, curious, and ready to contribute — I’d love to connect.
