I build the AI and digital systems businesses need but don't have in-house.
Payments, automation, backend, AI, and the web layer on top — designed, built, and shipped complete. Solo. From silicon to production APIs, I've built the hard parts most people outsource or fake.
What I build
AI assistants & automation
Assistants on your site or WhatsApp, and automations that kill the manual, repetitive work your team does by hand — wired into the tools you already run.
Payments & commerce
Checkout, recurring billing, usage metering, M-Pesa and Paystack — the full money layer, built to actually take payments in production.
Backend & platform engineering
APIs, dashboards, role-based access, database and POS integration, deployment and hosting on infrastructure that holds up.
Web & content systems
Fast, findable sites and the content engine behind them — one recording turned into everything, plus the SEO and discoverability to make it count.
Selected work
Roniki N1 — NPU
A neural processing unit designed from scratch: 64×64 systolic array, multi-precision, written in Amaranth HDL and verified in simulation. Silicon-level engineering.
Fikra — AI inference API
An OpenAI-compatible AI API with its own models, built with real billing infrastructure: recurring charges, prepaid usage balances, rate limiting, and regional failover.
Duka — merchant commerce
A commerce and payments platform for online sellers — storefront, checkout, and the full payment layer, live and taking real transactions.
