ROSHAN RAJ
Capabilities.
Bridging the gap between mathematical rigor in machine learning and robust architectural patterns in web systems.
Machine Learning & Data Science
Experience building robust active learning pipelines for material discovery and predictive modeling.
Full-Stack Web Development
Architecting responsive, high-performance web applications from database schemas to client interfaces.
Algorithms & Systems
Strong algorithmic foundation with 500+ competitive programming challenges solved. Proficient in lower-level logic and CI/CD tools.
My Approach.
Mathematical Rigor
Every system I build, whether a machine learning pipeline or a full-stack backend, begins with a strong foundation in logic, discrete mathematics, and algorithmic efficiency. No black boxes.
Scalable Architecture
I don't just build to make it work; I build to make it last. From database schemas to CI/CD pipelines, I prioritize robust, maintainable patterns over quick hacks.
Relentless Iteration
Drawing from my competitive programming background, I approach bugs and bottlenecks as puzzles. I profile, optimize, and iterate until the system hits peak performance.

Education & Honors.
IIT Bhilai
Competitive Programming
Solved 500+ problems across medium–hard difficulty. Strong algorithmic foundations in graph theory, dynamic programming, and advanced data structures.
JEE Advanced 2023
Cleared one of the most competitive engineering exams globally. Secured admission to IIT Bhilai, placing in the top 2% of 1M+ candidates.
Selected Works.
High-Entropy Thermoelectric Discovery
Screened 96,498 high-entropy candidate compositions using an active learning pipeline and Random Forest surrogate models. Evaluated only 0.08% of the design space to discover a top candidate with a predicted peak zT of 1.586. Validated models with cross-validation (R² > 0.9) and SHAP interpretability.
Second Brain Knowledge Manager
Developed a full-stack knowledge management app to create, organize, tag, and retrieve notes with instant search. Implemented RESTful backend APIs with authentication and persistent cloud storage. Designed a minimal UI focused on fast capture.
Live Cryptocurrency Dashboard
Engineered a real-time crypto analytics platform tracking live prices, market cap, and 24h volume for 100+ coins with auto-refreshing data via asynchronous REST API calls. Deployed on Vercel with CI/CD pipeline.
