Roshni Kobula Raja

MS in Computer Science, Binghamton. Ships agentic AI systems end to end, with the retrieval, ranking and test coverage to back them up.

Roshni is an AI/ML software engineer in the Bay Area working across Python, C++ and TypeScript: FastAPI and GraphQL backends, React frontends, RAG and hybrid vector search, LangGraph agents, and pytest/Playwright suites that run against Docker Compose. She built an agentic career-planning system for Binghamton’s Watson Career Services, cut document-processing time 40% at Kanini, and keeps winning at San Francisco hackathons on weekends. Debugs to root cause. Leaves tests behind.

Experience

Graduate Assistant

Binghamton University, SUNY

  • Architected an agentic AI system for career planning and role matching: skill-gap analysis and personalized learning roadmaps, with prompt engineering for role-fit explanations.
  • Partnered with Watson Career Services to gather requirements, test workflows and iterate on agent behavior from stakeholder feedback ahead of a planned release for student use.
  • The work grew into EvidPath, the full-stack career-planning platform.

Data Analyst Intern

Kanini

  • Shipped a full-stack document-analysis application with Django and Flask backed by PyTorch NLP pipelines, cutting manual processing time by 40%.
  • Built and deployed a document classification model pairing an SVM classifier with BERT embeddings, served through Flask APIs; also used OpenAI and Transformers embeddings.
  • Exposed REST APIs across the application for modular, reusable deployment, and built Python data pipelines and stakeholder dashboards.

AI/ML Intern

University of Texas at Dallas

  • Worked with a cross-functional research team on Python solutions for classifying and analyzing multimedia data.
  • Trained a music-genre classifier with K-Nearest Neighbors and scikit-learn, reaching 82% on GTZAN after hyperparameter tuning.
  • Implemented the MFCC feature-extraction pipeline (Librosa, NumPy) and the model-evaluation pipeline.

Hackathon highlights
Best Product and Best Use of Aria

CoreWeave Hacks: Agent Loops

We built Arian OS, agents that read a published ML paper and keep experimenting until a chosen metric improves. Two awards at one event, September 2026.

CASE STUDY
Second place

Better Days Hackathon

We built an early warning system that tracks how quickly river levels rise instead of waiting for rain. ClickHouse and LibreChat hosted it in San Francisco, August 2026.

CASE STUDY
Special mention, Qualcomm track

AI Infra Summit Hackathon

We built PEMA, an on-device assistant that remembers where objects were last seen for people with low vision or memory loss. Santa Clara, September 2026.

CASE STUDY

Twelve-plus hackathons so far, mostly in San Francisco. The rest of them, with photos, are on LinkedIn.
