Portfolio '26
Jefferson Ighalo
Full-stack & AI engineer taking ambiguous problems all the way to shipped products — LLM agents, zero-knowledge cryptography, and on-chain systems.
ScrollSelected work
Featured projects
Systems shipped end to end — from ZK circuits and Anchor programs to the frontends that demo them.
PromptFi
Send crypto to a face. Non-custodial payments locked to a recipient's facial identity — on-device embeddings verified on-chain with Groth16 zk-SNARKs.
HarvestFi
On-chain perpetual futures for real-world commodities — 71 markets at up to 10× leverage on a shared ETH liquidity pool, with transferable market-license NFTs earning 70% of trading fees. 70 fuzz & invariant tests.
Slingshot
A launchpad for AI agents that trade real tokenized stocks with their own money — each agent funds itself and trades SGOV, SLV, and GLD from its own ERC-4337 treasury, on-chain and custody-free.
TraceZero
A privacy protocol that breaks Solana's transaction graph — blind signatures, Groth16 proofs, stealth addresses, and Tor routing, with a TypeScript SDK.
AgentVault
The kill-switch layer for autonomous AI agents: shared USDC vaults with per-agent budget caps, instant revocation, and on-chain receipts as PDAs.
PolyMind
Open-source AI trading engine for Polymarket — a LangGraph research agent streaming its reasoning live, with human-in-the-loop execution.
Oneliac
ZK healthcare toolset on Solana — patient-eligibility proofs, encrypted IPFS medical data, and federated learning, across 6 repos with a Python SDK.
PerpsClaw
An AI-agent perps arena: three LLM traders with distinct personalities — momentum, mean-reversion, grid — trading SOL-PERP on Drift with a live reasoning feed.
WeatherClaw
A quant bot that arbitrages NOAA ensemble forecasts against Polymarket weather markets — signal, risk, and sizing engines with a full backtester.
Impact
Where I've worked
Eight years across payments, L2 infrastructure, developer platforms, and a venture studio of my own.
Chief Technology Officer · Independent AI Venture Studio
Founded and scaled a venture studio that launched 16+ blockchain products across Solana and BNB Chain, reaching $1.1M portfolio value. Led distributed engineering teams of 4–11 building AI trading platforms, DeFi protocols, payment systems, and MCP server infrastructure for the Solana ecosystem.
Director of Developer Relations · Monax Labs
Kickstarted the DevRel department from zero: wrote v1 of the API documentation, led hiring, built the client developer-network framework for big-ticket customers, and wired developer feedback directly into product and engineering decisions.
Founder · African Web3 Engineering Talent
Built a 900+ member community moving experienced African engineers into Web3, with learning paths from Solidity to growth engineering. Funded by the Findora Foundation.
Senior Developer Relations Engineer · Wyre
Wrote v3 of the docs and led a 20-person effort revamping APIs, documentation, and developer onboarding for the payments platform.
Head Documentation Engineer · Polygon
Refined and redesigned Polygon's developer documentation for the company's new direction, setting the site-wide writing style for developers integrating with the network.
Lead Software Engineer · SystemSpecs
Led frontend on Remita Inline (payments) and built internal ERP tools in React, Gatsby, and Angular, with Docker and Redis on the DevOps side.
Software Engineer · Andela & LandLagos
Engineering at Andela; consultant frontend developer at LandLagos.com building the eCommerce experience in Vue, then React.
About
Builder of shipped things
I take ambiguous problems all the way to shipped products. Based in the UK; previously at Polygon, Wyre, Monax Labs, and Andela. Over the last four years I've shipped 30+ systems solo — trading engines, ZK protocols, agent infrastructure, and the production frontends that make them usable.
Right now I'm building at the intersection of AI and on-chain products: agents that trade, remember verifiably, and spend within cryptographically enforced budgets — shipping fast, measuring, iterating.
AI Engineering
LLM agents and their infrastructure — memory, treasuries, orchestration, multimodal systems.
Zero-Knowledge Cryptography
Groth16 circuits, blind signatures, stealth addresses — in production, not just papers.
Full-Stack Product
React/Next.js interfaces on type-safe TypeScript/Node services, shipped with tight loops.
Web3 / Blockchain
Solana (Anchor/Rust) and EVM — DeFi tooling, trading systems, on-chain data.
