Hi, I'm Arjun S. Nair

Ml/AI Developer & AI Researcher | Microsoft Student Ambassador | Postman Student Leader

I am a Software Development Engineer (SDE-2) with over 5 years of professional experience and more than 10 years of software development contributions. As the founder of Cmakers and creator of multiple innovative projects, I specialize in full-stack development, systems programming, and AI research.

Current Work & Research

  • AI Research: Published researcher in ML and AI with peer-reviewed work on:
    • DHGRPO (Domain-Induced Hierarchical Group Relative Policy Optimization) - a novel extension of Group Relative Policy Optimization for robust preference-based fine-tuning of large language models DOI
    • Calibration Meets Reality: Making Machine Learning Predictions Trustworthy - rigorous theoretical analysis of post-hoc calibration methods with convergence guarantees arXiv
    • Impossibility Theorem for Confidence Calibration: Proving neural networks cannot learn well-calibrated confidence estimates with meaningful diversity under binary supervision arXiv
  • Live LLM Development: Building a custom large language model with a hybrid tokenizer featuring 200k+ vocabulary tokens, surpassing GPT-4's CL100K base tokenizer performance
  • Systems Architecture: Developing new AI system architectures and low-level implementations
