Hi, I’m Jayani! I’m a senior studying Computer Science at North Carolina State University, passionate about building software that challenges me to think differently and creates a meaningful impact. My interests sit at the intersection of backend engineering, applied AI, and reliable software systems.

Most recently, I worked as a Software Engineering Intern at Fidelity Investments on a trading engineering team. I modernized identity and authorization workflows by integrating enterprise APIs with an existing legacy system. I also built an agentic AI performance-testing workflow that automated five stages—from generating hypotheses and collecting metrics to analyzing results and providing insights—which reduced manual test-analysis time and is reusable across different teams.

In the Game2Learn Lab, I worked on MerryQuery, an AI tutor for intro programming. I put together a Direct Preference Optimization (DPO) fine-tuning pipeline so the tutor’s explanations line up with rubric-style feedback from teaching assistants. I also added a retrieval-augmented generation (RAG) layer so answers pull from approved course materials instead of guessing. The goal was simple: clearer help for students, less cleanup for instructors.

I also help run student engagement for WiCS at NC State. I organize events and mentorship touchpoints for first- and second-year students.

I’m seeking full-time software engineering opportunities with teams that value readable code, thoughtful experimentation, and strong feedback loops. I’m especially interested in backend engineering and applied AI. If that’s your world, I’d love to connect!
