Products in the world
Four of these are live and anyone can download or buy them. The rest is earlier work, coursework and things I built to learn.
Pocket Shop
CTO · Pocketshop Market Limited
A marketplace for Zambia putting local shops, mobile money and delivery riders in one app. Payouts run through MTN, Airtel and Zamtel, and sellers only pay a fee when something sells.
Groundr
Co-founder · Impiy Technologies
Trust infrastructure for AI. Groundr breaks model output into atomic claims, arbitrates them across several frontier models, then checks each one against live sources — catching consensus hallucinations where every model agrees but no evidence exists.
Rolade POS
Developer
An offline-first point-of-sale system for Zambian shops covering invoicing, inventory and wholesale pricing. Stock cannot go negative, and bulk prices adjust themselves at the counter.

02 — About
How I got here
I lead engineering at two companies. At LVX Technologies I'm CTO of TAG, a social app built so you can be reachable without handing out your real phone number. At Pocketshop Market I'm CTO of Pocket Shop, a marketplace that ties shops, mobile money and delivery riders together in one app. Both have shipped through Apple and Google review and are live on the App Store and Google Play.
Alongside that I co-founded Impiy Technologies, where I work on Groundr — a verification layer that checks what AI models claim against real evidence — and IMPI08, a QR payments and escrow platform.
I'm finishing Computer Engineering at the Copperbelt University. Before any of the above I was writing trading bots in MQL5 and desktop software in C#, which is still the part of the job I enjoy most: something that runs on a machine and does a job every day.
I work from Zambia with anyone, anywhere. The problems I like — payments that clear, stock that reconciles, claims that hold up — are the same everywhere.
