Sachin Kumar

Full-Stack Web3 & AI Engineer.
Building

I design, build, and audit smart contracts across EVM chains, and build the autonomous multi-agent AI that operates them. From prediction markets and on-chain savings to trustless oracles.

About

Smart contracts, AI agents, and the full-stack products that tie them together.

I'm a Web3 & AI engineer. I write and audit the smart contracts that move value on-chain, build the multi-agent AI that automates decisions on top of them, and ship the full-stack apps around both.

Blockchain

Secure Solidity across EVM chains. Foundry, gas-efficient patterns, reentrancy-safe design, and test suites that catch bugs before they ship.

AI Engineering

Multi-agent systems and LLM orchestration. MCP tools, RAG, and primary-fallback consensus pipelines that make autonomous decisions.

Full-Stack

The product around it: React 19, Next.js, tRPC, and Fastify/Postgres/Redis services, wired to on-chain indexers and wallet auth.

Telshi

Web3 · Full-Stack

Live

Decentralized binary prediction market on Base L2

A full-stack prediction market: an 8-app monorepo with 14 real-time services, contracts to client.

▹5 Foundry contracts with an EIP-7702 gasless relay & USDC settlement, 0 failed txns across 2,000+ ops.
▹React 19 + tRPC over Fastify/Postgres/Redis, driven by 14 background services for live order matching.

Omenly

AI · Agents

Live

Trustless oracle layer for prediction markets

A 4-agent consensus engine that reads on- and off-chain data and settles markets on its own.

▹Weighted-confidence consensus across 4 agents settles outcomes autonomously at 99.2% accuracy.
▹Primary-fallback LLM chains with MCP tools (Nansen, Polygon, web search) and <200ms failover.

Live

On-chain rotating savings circles (ROSCA) on Base

Savings circles with VRF-random or sealed-bid payouts — $50-$500 monthly across up to 10 members.

▹EIP-1167 clone factory + over-collateralized loans with Chainlink feeds and automated liquidation.
▹Next.js front-end with a Ponder on-chain indexer and headless Dynamic Labs (JWKS) auth.
