Everything I have built

Live

01 Flagship

AHIA

Multi-tenant retail platform for small traders, delivered as a FastAPI backend, a Next.js web app, and an offline-first mobile client that ships as an installable Android build. Every business-owned table carries a row-level security policy bound per transaction, so a missing filter returns nothing rather than another shop's data. Sales, payments, stock movements, expenses and audit events are append-only ledgers committed together, and a device that goes offline pushes idempotent operations through a sync service that cannot apply a sale twice. Customers build a list from a public link with no account, the trader prices and sources it, and dispatch records the waybill. The suite runs past two thousand tests, including architecture contracts that fail the build on a layering violation.

02 Flagship

kssrag

Retrieval-augmented generation framework published on PyPI, built around one command: point the CLI at a document and it loads, chunks, indexes, and serves a FastAPI endpoint with token-by-token SSE streaming and per-session conversation memory. Six vector stores and two retrievers are chosen by config or replaced with your own classes by import path, and any hosted or local model provider can be swapped with a single flag, with automatic fallback when one is unavailable.

03 Flagship

Gigr

Neighborhood marketplace on Solana, built as the repository BAROS. On-chain escrow and PostGIS-backed local matching, with reputation minted as compressed NFTs so a vouch cannot be quietly edited or deleted later. Wallets are provisioned at registration to keep seed phrases out of the user's path, and an AI assistant can post jobs and negotiate on the user's behalf. Currently in pilot.

04 Flagship

CongestIQ

Multi-agent reinforcement learning for adaptive congestion control. Several flows learn to share a bottleneck under centralised training and decentralised execution, with a cooperative reward that charges queueing delay, loss and window growth so no agent simply fills the buffer. The policies are developed against ns-3 and benchmarked against Reno, CUBIC and BBR on the same two-flow dumbbell topology.

05 Flagship

driftlock

Commit-time gatekeeper that catches documentation drift before it lands. It parses staged diffs, detects API-surface and structural changes across languages, then either blocks the commit or rewrites the affected docs through an LLM. Ships as a standalone CLI, a pre-commit hook, and a GitHub Action, with optional anchoring of each doc-sync check to Solana for a tamper-evident audit trail.

06

AutoSig

Multi-agent trading system for Solana, built for Superteam Nigeria's Agentic Wallets challenge. LLM agents propose trades, but nothing reaches the chain until it clears three independent gates: hard limits no model can override, deterministic policy checks, and a second model acting as reviewer. An adversarial test suite verifies the guardrails still hold when the proposing agent is actively trying to break them.

07

RepEngine

Freelance marketplace and reputation-weighted DAO built to price trust cryptographically instead of trusting a profile nobody verified. Job access and voting power are both gated on on-chain reputation through the FairScale API, so a new wallet cannot buy its way into governance. Full-stack with a live deployment.

Ginger Copilot

Agentic intent solver for the Injective chain with hardware-enforced execution. The intelligence layer reads live chain state, monitors staking rewards and builds CosmWasm payloads while holding no private keys at all. Each intent is handed to a Ledger device, reviewed and clear-signed by a human, and broadcast only after explicit approval on the hardware.

09

Healthcare Diagnostic API

Multi-tenant FastAPI backend for healthcare records covering patients, test requests, and lab results. Authorization follows the AWS IAM shape, where atomic permissions compose into permission sets and then into roles. Records use soft deletes to keep an auditable history, and credentials are hashed with Argon2.

LexAI

Question answering over the Nigerian Constitution with a hybrid retriever that pairs FAISS vector search against BM25 keyword scoring, so exact statutory phrasing and paraphrased questions both retrieve the right passage.

Patient Management Microservices

Patient management split into independent Spring Boot services for patients, authentication, appointments, billing, and analytics, communicating over Kafka events, REST, and gRPC where a synchronous call is the right shape. The whole environment is provisioned with AWS CDK against LocalStack to emulate ECS locally.

CIAP

Creator analytics platform for the African creator economy. It aggregates cross-platform metrics into influence scores, then exposes creator discovery and campaign planning to the agencies and brands doing the hiring. FastAPI and PostgreSQL behind a typed client, with YouTube analytics as the first integration.

Pharmacy AI Agent

Prescription processing and inventory system. PaddleOCR extracts text from a photograph of a prescription, an LLM structures that text into validated fields and corrects what OCR got wrong, and the result feeds multi-tenant inventory with demand forecasting.
