I'm a software engineer in Nigeria. I build applications, smart contracts and AI agents, mostly where software touches money, governance or infrastructure, and I contribute to the open-source projects around them.

Online I'm Harystyles, which means Harrison's way of doing things. In practice: make it work, read it back, revise it until it's right. That goes for code and for writing.

CareGuard: an AI agent that manages an elderly parent's healthcare spending, inside limits a caregiver sets.
It compares medication prices, audits medical bills for errors and pays in USDC on Stellar. A spending-policy engine enforces daily and monthly limits, category budgets and approval thresholds. Built in the open, with CI, tests, architecture decision records and a generated OpenAPI spec.

Runs on Stellar testnet. The payments are real transactions, but not on mainnet.

DCFR: a file repository that answers to its community.
Winner, Track 2, HackSecret 5 (Autonomys Auto Drive). Members propose uploads, deletions and shares and vote on them. FileDAO.sol executes the proposals that pass, and Auto Drive keeps the files permanent, so no single administrator decides what stays.

Dispatch: from a headline to a routed trade.
Winner, LI.FI Agentic Commerce API Vibeathon. An agent that reads market-relevant news and routes trades across chains through LI.FI.

Experimental. A hackathon project, not a trading product: it makes no claim of profitability.

ChainGuard: a Uniswap v4 hook that notices when a pool is being misused.
My capstone for the Uniswap Hook Incubator (UHI8). It is a security-focused concept for monitoring swap activity and flagging anomalous behaviour inside the hook lifecycle.

Drips: contributor and maintainer. API validation and error handling, frontend fixes, regression tests.
GrantFox: contributor and maintainer. Issue resolution, debugging, upkeep of developer-facing workflows. Contributions · Maintainer profile
Akash Network: Akash Insider. Documentation fixes, Akash VPN, developer onboarding, hackathons in Lagos.
Core DAO: DevRel and technical ambassador. Meetups, hackathons and workshops for builders.
NodeBridge Africa: operated Ethereum validator infrastructure, monitored with Prometheus and Grafana, and taught 300+ students through webinars and events.

Technical writing is how I explain how things work. Poetry, essays and long reflections are where I work out what they mean.

I'm gathering the first pieces now. They'll be listed here once they're published, not before.

I'm open to engineering roles, open-source collaboration and well-scoped contract work, especially in Web3 infrastructure, AI agents and developer experience.
