Open to engineering, product, and AI roles · Currently at Neo Health

Engineer, builder, and product thinker — shipping AI infrastructure, fintech systems, and the interfaces that tie them together.

From AI agent security platforms to banking-as-a-service infrastructure to a health wallet I built end-to-end — I work across the full depth of a product, not just its surface. Engineering is how I think. Shipping is how I measure.

Selected Work

Production systems,
shipped and in use.

AI infrastructure, fintech, and product work — running in production with real users. Each links directly to the live product.

Detecte — AI agent security platform

01 · AI Infrastructure · Security · TypeScript SDK

Detecte — AI Agent Security Platform

The first KYC/AML platform for AI agents. The idea is simple: if humans get verified before they access financial systems, AI agents should too. Detecte does this in two layers — Know Your Agent (KYA) verifies agents at onboarding, and continuous behavioral monitoring flags drift, permission escalation, and anomaly in real time.

Full production stack: Hono API (25 endpoints), Next.js dashboard with Clerk auth, TypeScript SDK (@detecte/sdk on npm), Python package on PyPI, CLI tool, Stripe billing, real-time SSE streaming, and a visual policy builder.

Role — Built end-to-end — API architecture, SDK design, dashboard, billing system, and the behavioral monitoring engine. Shipped solo.

Vezra — multi-LLM AI workforce platform

02 · AI Platform · LLM Orchestration · Enterprise

Vezra — Multi-LLM AI Workforce Platform

A multi-LLM AI workforce platform with 28+ business tool connectors, per-org isolated containers, multi-model routing, and a zero-trust agent model. Named AI workers — Finance Worker, Support Worker, Compliance Worker — execute real operational tasks across connected business infrastructure rather than answering questions in a chat window.

Built for enterprise: per-org isolation, audit logging, role-based access, and model-agnostic routing that lets organizations switch or blend models without rewriting their workflows.

Role — Built the platform architecture, LLM orchestration layer, connector system, and enterprise onboarding. Pricing spans $49 Starter to Enterprise custom contracts.

Neo Health — health wallet (Slate)

03 · Healthcare · Fintech · Product · Full-Stack

Neo Health — Health Wallet (Slate)

Built the health wallet product end-to-end — not just the frontend. Slate is a financial platform for healthcare: patients manage wallet balances, track spending, make payments to providers, and move money through health-specific workflows. Providers get visibility into payment status, claim flows, and patient financial activity.

The product spans wallet infrastructure, payment API integration, transaction processing, approval workflows, and the interfaces that make all of it navigable for both technical and non-technical users. Built with React, Next.js, TypeScript, and Tailwind on the frontend, integrated with REST and GraphQL APIs for real-time financial data, with a shared design system and component architecture across patient and provider surfaces. This isn't a UI over someone else's product. It's the product.

Role — Product architecture, frontend systems, API integration, design system, and end-to-end delivery.

Fintava — banking-as-a-service platform

04 · Fintech · BaaS · Core Banking

Fintava — Banking-as-a-Service Platform

A banking-as-a-service platform that has processed over $150M in transaction volume. Fintava provides card issuance, payment rails, account infrastructure, and financial product APIs to fintech operators and neobanks who need banking capabilities without a banking license.

The frontend spans merchant dashboards, transaction monitoring, account management, and internal operational tooling — built to handle high-volume, real-time financial data without becoming a wall of numbers.

Role — Frontend architecture and delivery across all platform surfaces. Design system, data-dense dashboard interfaces, and API integration across payment processors and banking networks.

Qulture — social discovery platform

05 · Social · Mobile · React

Qulture — Social Discovery Platform

A social events and discovery platform built around moments, challenges, and community participation. Users discover local hotspots, participate in shared experiences, and connect around things happening in their city rather than things they've already done.

Built with React and Tailwind. Designed around a core interaction model that makes discovery feel immediate — not algorithmic.

Role — Frontend architecture, interaction design, and component system.

Finstore — e-commerce platform for African merchants

06 · Commerce · E-commerce · React · Next.js

Finstore — E-commerce Platform for Merchants

A free e-commerce platform built for African merchants — specifically designed for businesses that need a professional online store without the complexity or cost of platforms built for Western markets. 5,000+ merchants onboarded across Nigeria.

Includes merchant storefront templates built with Next.js and React — optimized for mobile-first markets, fast load times on lower-bandwidth connections, and conversion-focused layouts for physical product sellers.

Role — Platform architecture, storefront template system, and merchant onboarding experience.

Cardex — card payments platform

07 · Fintech · Payments · Card Infrastructure

Cardex — Card Payments Platform

A card payment platform supporting Verve, Visa, and Mastercard — built for the West African payments market. Cardex provides card issuance infrastructure, transaction processing, and merchant acceptance for businesses operating across Nigeria and broader West Africa.

Role — Frontend delivery across the platform dashboard, card management interfaces, and transaction reporting.

About

How I approach the work.

I build production systems — not prototypes, not demos. The things I make go live, handle real users, and operate in domains where getting it wrong has consequences.

My work spans AI infrastructure, core banking, payments, healthcare, and commerce. I built Detecte — a KYC/AML platform for AI agents, with a TypeScript SDK on npm, a Python package on PyPI, 25 API endpoints, Stripe billing, and real-time behavioral monitoring running in production. I built Vezra — a multi-LLM AI workforce platform with 28+ business tool connectors, multi-model routing, and a zero-trust agent model for enterprise operations. I co-built Fintava, a banking-as-a-service platform that has processed over $150M in transaction volume. At Accenture, I managed enterprise AI product delivery for large-scale organizations. At Neo Health, I built the health wallet product end-to-end — wallet infrastructure, payment flows, provider and patient interfaces, and the full delivery of a financial platform where clarity and reliability are not optional.

Front-end is where I'm most precise — React, TypeScript, Next.js, design systems, performance — but it's not where I stop. I understand the API contracts behind the UI, the infrastructure decisions that affect what's even possible to build, and the product thinking that determines whether any of it matters.

If you're building something real and you need someone who will own it — not just implement a spec — that's where I do my best work.
