I’m an engineering leader and hands-on AI/ML builder, focused on deeply understanding and implementing the nuts and bolts of modern LLMs. From training tokenizers and building BPE from scratch, to implementing transformers line-by-line, I love demystifying AI—one project and one workshop at a time.
| Project | What I Did |
|---|---|
| 🧩 Byte Pair Encoding (BPE) from Scratch | Wrote a custom BPE tokenizer in Python with support for special tokens, regex splitting, and vocab merging. |
| 🧠 LLM from Scratch | Implemented a transformer-based LLM (embedding → attention → MLP → logits) using only PyTorch. Includes training loop, sampling, and inference. |
| 🦙 Agentic RAG Pipeline | Built end-to-end Retrieval-Augmented Generation workflows using LangChain, DuckDB, FAISS, and streaming token-by-token inference. |
| 📊 Text-to-SQL for CSVs | Built a system to parse natural language queries into SQL and run them over uploaded CSVs. Added Vespa-style search for LIKE queries. |
| 🇮🇳 Hindi Tokenizer (WIP) | Training a BPE tokenizer from scratch on Hindi corpora to enable better subword tokenization for Indian languages. |
| 🔐 Secure LLM Workflows | Integrated Cloudflare Zero Trust, IP whitelisting, and API key validation in LangChain-based pipelines. |
| 📦 SmartInvestReturns | A personal finance site to calculate SIP, retirement corpus, and mutual fund strategies. Built with Next.js & TypeScript. |

🧠 RAG Beyond Basics Workshop
Covers advanced topics like agentic workflows, text-to-SQL, streaming outputs, observability, and PII-safe deployments.
Delivered at internal events, React Summit 2024, and community meetups.
