Services

I work with founders and teams directly, or through Adewumi Studio for full builds.

Product Engineering

End-to-end builds — marketplaces, commerce platforms, EMRs. From architecture to a shipped, tested product on Next.js, Supabase, and Payload.

AI Integration & Automation

Practical AI in real products: LLM-powered features, RAG pipelines, WhatsApp automation, and workflow tooling that pays for itself.

Technical Consultation

Architecture reviews, digital strategy, and roadmaps. A second brain for founders deciding what to build, how, and in what order.

What I bring

Not a list of logos — each of these points at something shipped.

Full-stack product engineering

One engineer from database schema to polished UI — no handoffs, no gaps between design and build.

Proof: Six platforms shipped end-to-end

Next.js · React · TypeScript · Tailwind · Turborepo

Commerce & payments

Checkouts where the server owns the money math — no client-trusted totals, no leaking revenue.

Proof: Server-side re-pricing on Melanin Skin City

Paystack · Stripe · Payload CMS

Data & backend

Postgres-backed systems designed for the day two problems: migrations, idempotency, and audit trails.

Proof: EMR + marketplace backends in production

Supabase · Postgres · Payload CMS

Messaging & automation

Products that live where Nigerian users actually are — WhatsApp — with the web doing the heavy lifting.

Proof: Nafara's WhatsApp-first booking

WhatsApp / Meta Cloud API

Testing & reliability

Test suites that make Friday deploys boring. If it matters, it has a test.

Proof: 535+ automated tests on Nafara

TDD · CI/CD

Privacy & compliance

Consent-gated features and owner-only data models, designed against NDPA from day one.

Proof: iWoman's privacy-first cycle tracker
