Overview

Built Necta as sole engineer — an AI-powered stablecoin yield platform using a multi-agent architecture. Three specialized agents (Sentinel, Curator, Executor) work together to automatically optimize yield strategies across DeFi protocols, fully on-chain and self-custodial.

Problem

DeFi yield optimization requires constant manual monitoring across multiple protocols — most users miss better opportunities or lose returns through inaction.

What I Built

Designed and built the full product end-to-end — frontend dashboard, backend API, smart contracts, and a multi-agent AI system. Three specialized agents (Sentinel, Curator, Executor) collaborate to automatically optimize yield strategies across DeFi protocols.

Challenges

Coordinating multiple AI agents reliably on-chain was the hardest technical problem. Ensuring the agents made safe, non-destructive decisions with user funds required extensive testing and conservative guardrails.

Outcome

Shipped from concept to live beta in 10 months as sole engineer.
