The work, the decisions, and what you can verify.

I work across backend systems and product delivery. These examples separate commercial responsibility from my independent products and open-source work.

01 / Commercial product ownership

GlobalMPC

Taking a Web3 product from roadmap to mainnet.

My scope
Technical Product Owner at GlobalMPC, responsible for blockchain onboarding and a self-custody Flutter wallet. Separately, my backend work at Must Company / MSQUARE Global supports a fintech platform serving 90,000 daily active users.
Engineering decisions
I own roadmap, OKRs and release decisions. The product combines a self-custody wallet and on-chain rewards. Security review and a documented release checklist were part of the launch decision.
Evidence and limits
The waitlist product with sponsored on-chain check-in shipped to BNB Smart Chain mainnet in August 2026. I can discuss architecture and release tradeoffs without exposing internal code or customer data.

02 / Commercial mobile, backend and AI engineering

Shelta Panacea

Connecting mobile financial workflows with an AI and operations platform.

My scope
As Lead Mobile & AI Engineer (Full-Stack), my work spans the Flutter app, backend API integration and Shelta AI. The mobile product covers rent and property workflows, landlord journeys, COVA redemption and community notifications. Shelta AI adds a Next.js and TypeScript application with streaming chat, retrieval, voice transcription and CRM tools.
Engineering decisions
The retrieval service uses PostgreSQL and pgvector to select relevant knowledge instead of attaching the entire knowledge base. Existing service interfaces were retained through the storage migration. Mobile release tooling distinguishes development and production builds and checks version codes to reduce stale-build distribution.
Evidence and limits
The implementation includes Drizzle database migrations, scoped retrieval, model-provider selection, activity logging and push services. I can explain the architecture and my contributions in an interview; private source code and user data are not published here.

03 / Independent open-source engineering

Sether

Handling sensitive data at the model boundary.

My scope
I built a streaming-native redaction library for AI applications, published on npm and PyPI. It replaces detected sensitive values before they reach a model provider and supports restoring values in responses.
Engineering decisions
Streaming changes the problem: a sensitive value can cross chunk boundaries. Detection, reversible substitutions and response restoration need explicit tests, including incomplete inputs and false positives.
Evidence and limits
The package and browser sandbox make the behavior inspectable. Detection has limits: patterns do not cover every possible name or data shape. This is an engineering control, not a guarantee of security or regulatory compliance.

04 / Independent product engineering

Trackshon

Turning a product URL into a useful next step.

My scope
I built a product that helps founders inspect their positioning, prioritize improvements and find relevant public conversations. It connects product analysis with customer discovery.
Engineering decisions
The user reviews the fit and decides what to publish. Source availability and match quality are explicit limitations. A score needs an explanation that a person can inspect and challenge.
Evidence and limits
The public preview lets you explore the workflow. I can walk through the product decisions and implementation; the preview is not a claim of customer adoption or revenue.

Mobile and Rust are part of the picture.

My wider work includes Flutter applications, a Flutter and Rust reader, and published Rust supply-chain tools. I use these where the product needs mobile delivery, local processing, or a focused command-line tool.

Have a relevant engineering role?

I’m based in Abuja, Nigeria (UTC+1), open to international remote work and relocation to Germany. My focus is senior backend and product engineering with TypeScript, NestJS and Next.js, including AI applications and developer tools.
