Hi, I'm Kunal Yadav 👋

B.Tech Instrumentation & Control Engineering @ NSUT

I build high assurance systems at the intersection of Bitcoin privacy and local-first AI. Currently a core contributor to the Jam ecosystem.

🏆 Key Achievements

• SIH 2025 Winner: Developed GroundSense Bot for the Ministry of Jal Shakti. Engineered an offline RAG system processing 27k+ groundwater datasets with deterministic SQL generation.
• Jam Organization Member: Integrated core privacy infrastructure and advanced wallet logic into the JoinMarket WebUI.

₿ Open Source: Jam (JoinMarket)

Focus: Security-critical wallet logic and protocol implementations.

• Fidelity Bonds Module: Designed the end-to-end creation and renewal workflow, orchestrating timelocked UTXO management and BIP-32 derivation.
• Power User Infrastructure: Built the advanced wallet interface for granular xpub/zpub management and privacy-sensitive data exposure.
• Architecture: Managed complex state synchronization between React and the JoinMarket API within Dockerized regtest environments.

🤖 AI Engineering: GroundSense (SIH 2025)

Focus: Reliable, zero-dependency AI for government-scale data.

• Offline RAG Pipeline: Orchestrated Ollama + Qwen 2.5 for natural language querying of structured government data.
• Vector Search: Implemented semantic retrieval using PostgreSQL + pgvector with a custom Redis caching layer for sub-second response times.

Tooling & Environment

🛡️ Testing & Reliability Arsenal

Because in Bitcoin, there are no "undo" buttons.

• Execution: Specialized in Dockerized Regtest environments for Bitcoin protocol simulation.
• Unit/Integration: Jest and React Testing Library for frontend state logic and Pytest for backend validation.
