WordPress SaaS engineering

I ship production SaaS on WordPress.

Three live platforms. Fifty-three custom plugins. Multi-tenant architectures, recurring Paystack billing in Naira and US dollars, three-stream affiliate commissions, multi-currency accounting, eight-country tax calculators, multi-campus school finance. Engineered solo, in production, on cloud infrastructure.

Three platforms.
Three verticals.
One developer.

Each platform was architected, built, and shipped solo — from database schema to Paystack webhook to admin UX. No boilerplate frameworks. Native WordPress APIs. Production traffic.
What I build

Engineering, not theme-flipping.

Every offering below is grounded in production work — no theoretical service descriptions. If you've seen the case studies, you've seen each of these shipping in real platforms.
/01

Custom WordPress plugins, built from scratch

Bespoke plugins designed around your data model, not bent around someone else's. Native WordPress APIs, prepared statements, capability checks, WP-Cron for scheduled work. Zero off-the-shelf membership or LMS plugins required.

PHP 8 · MySQL · Native WP · No build pipeline
/02

SaaS architectures with Paystack billing

Recurring subscriptions, one-time charges, multi-currency support (NGN, USD, GBP), HMAC-verified webhooks, retry logic, kill switches, idempotent payouts at the database level. Both tiered and flat-rate billing models shipped.

Paystack · Webhook verification · WP-Cron · Idempotency keys
/03

Multi-tenant + multi-role platforms

HQ-and-branch hierarchies. Per-tenant data isolation enforced at the query layer. Custom role hierarchies (super admin, HQ admin, branch manager, finance volunteer, subscriber). Approval workflows for transactions that need oversight.

Custom user meta · Capability mapping · Filtered queries
/04

Automation: Make.com, Twilio, Telegram

Webhook-driven workflows connecting WordPress to Make.com, Twilio SMS, and Telegram bots. Routing rules, message templates, scheduled reminders, channel segmentation. Production-tested on a live signals business and a ministry summit platform.

Make.com · Twilio · Telegram Bot API · REST

Also offered: editorial design, magazine layout, book formatting, and Amazon publishing — the design side of Dunamis Code & Visuals. Useful if your project needs both engineering and visual identity in one place.

About

I'm a solo engineer who has shipped three production SaaS platforms in the past year — across faith-based community, church finance, and multi-vertical African fintech.

I work entirely on the WordPress runtime by choice: it's portable, well-understood, and pairs cleanly with shared Nigerian hosting that real African clients actually use. The platforms I build use native WordPress APIs end-to-end — no boilerplate frameworks, no heavy JavaScript build pipelines, no off-the-shelf membership or LMS plugins.

I also lead a small creative studio, Dunamis Code & Visuals, handling editorial and brand design for ministries and small businesses. The dual practice means I usually ship interfaces that look as considered as they function.

Also shipped

Selected websites & brand work.

Production websites built or designed across ministries, events, healthcare, and leadership programmes — alongside the SaaS work.

I take on a small number of senior engineering engagements at a time — custom plugin builds, SaaS platforms, payment integrations, and complex WordPress architectures. If your project needs more than theme-flipping, I'm a good fit.
