Things I have worked on

Sanchay AI Harness - Agentic Automation with Human-in-the-Loop

Systems level Personal Project · Aug. 2026

Built a bounded tool-calling agent loop (max 6 turns) using Groq with function calling, operating over a curated registry of 13 typed tools with strict risk classification. Designed a two-phase execution model: READ-risk tools execute inline for reasoning, WRITE-risk tools are staged into persisted action plans requiring explicit human approval before a transactional executor runs them with automatic rollback on failure. Implemented the security boundary where risk class comes from the server-side tool registry, never from the request body, preventing prompt-injection escalation attacks.

Distributed Event-Ticketing Platform

Systems level Personal Project · Aug. 2026

Merged CDC pipeline, Rust load balancer (P2C + health signals), and Node.js backend into a unified distributed system in 3 days. Zero-polling real-time sync via Postgres WAL → Debezium → Kafka → Redis → WebSockets.

Node.js, Rust, Kafka, Redis, PostgreSQL, WebSockets

Operations MCP - LP-Powered Business Problem Solver

Full Stack SaaS Project · Jul. 2026

Wrapped Linear Programming algorithms (Simplex, Dual Simplex, Gomory) in a Model Context Protocol so LLMs can autonomously reason over and solve structured business optimization problems. Built a full-stack API platform with JWT authentication and API key management to expose the Operations MCP as a production-grade service.

EdgeSLM - Smart Store Assistant

Edge AI Personal Project · May. 2026

Built a voice-enabled recommender running a swappable Small Language Model locally on Raspberry Pi 5 using FastAPI, WebSockets, llama.cpp, Whisper, and Piper. Implemented FAISS-backed RAG with rule-based clarification and deterministic fallback, keeping the assistant operational even without downloaded models. Built a minimal browser UI on LAN for voice and chat interaction.

Python, FastAPI, WebSockets, llama.cpp, Whisper, Piper, FAISS

Athena - Personal Intelligence Layer + Digital Clone

Systems level Personal Project · Aug. 2026

Built a local intelligence daemon with an identity core, knowledge graph, dialogue engine, privacy kernel, and action ledger, all running as a persistent Python service. Enforced graduated autonomy boundaries at the code level so the agent never acts outside user-defined limits, exposing a localhost API for external surfaces.

Lumea

Co-Code Hackathon 2026 - 2nd Place · Jan. 2026

A platform which checks the reports of the patient, calculates a health index, uses context and AI integrations like chatbots and voice agents with whatsapp reminders - My role was to dockerize, overlook the entire thing and add security features

Lattice

Systems level Personal Project · Jan. 2026

Designed a BitTorrent-inspired protocol covering peer discovery, metadata exchange and handshake procedures. Implemented chunked streaming for multi-GB file transfers. Built SHA-256 based integrity verification and deterministic file reconstruction logic.

TypeScript, Bun, TCP/IP

Collaborative Project · Dec. 2025

A discord RPG Game featuring a full fledged Economy, Shop and NPCs

TypeScript, Discord.js

Lazy Certificate

Automation Project · Nov. 2025

Engineered a bulk automation system to generate personalized certificates by binding structured data to Canva templates. Integrated with Canva's SDK to enable seamless rendering and export of dynamically generated assets.
