Portrait of Ayodeji Adeniyi
Fig. 01 — A. Adeniyi

I build products twice — first as a strategist, then as an engineer. Over the last 5+ years I've shipped AI-powered products for African markets: a digital health platform that reached 10,000+ users, a dating app that lifted retention from 45% to 75%, and booking infrastructure for interstate travel.

I work across the whole stack of product-making. On one side: user research, roadmaps, A/B tests and go-to-market. On the other: React, TypeScript and Supabase. This page is part of the argument — designed, written and animated by hand, shipping zero JavaScript.

AI-native product studio — idea to shipped product, in weeks

Àrà logo
ara.ayodeji.xyz

Overview

Àrà (ah-RAH — Yorùbá for "wonders, the never-seen-before") is an AI-native product studio based in Abuja, Nigeria. It offers fixed-scope, fixed-price builds: AI opportunity audits, six-week MVPs, AI integration sprints, and an always-on design & build subscription.

Key Features

  • Two live AI tools embedded in the landing page — "Audit my business" and "Spec my idea" — powered by server-side Gemini with structured output.
  • A design system built from Nigerian textile traditions — Adire, Aso-oke, Uli linework and Benin coral beads — with an interactive Design Lab.
  • Supabase-backed booking flow with a never-fail mailto fallback.
  • Fully honors reduced-motion preferences across every animation.

TechiesMatch

AI-powered dating for tech professionals — retention 45% → 75%

TechiesMatch logo
techies.love

The Challenge

The online dating market is saturated, but we identified a gap for tech professionals who seek partners with similar interests and career paths. Mainstream apps often failed to capture the nuances of this demographic, leading to low-quality matches and user fatigue.

The Process & Solution

The core innovation was a machine learning algorithm that went beyond simple profile data. It analyzed users' interests, communication styles, and in-app behavior to predict compatibility, resulting in a 40% improvement in match compatibility rates. I also designed an A/B testing plan for the onboarding flow, which reduced the drop-off rate by 28%.

The Impact

  • User retention increased from 45% to 75%, a 67% improvement.
  • AI-driven match recommendations led to a 35% increase in daily active users.

HealthTrackNG

Digital health access for underserved communities — 10,000+ users

HealthTrackNG logo
healthtrack-ng-connect.vercel.app

The Challenge

In many underserved communities across Nigeria, accessing healthcare is a significant challenge. Patients face long wait times, a lack of information about available services, and difficulties in booking appointments, especially in low-connectivity environments.

The Process & Solution

Based on on-the-ground user research, we prioritized core accessibility features like offline functionality and multilingual support (English, Hausa, Yoruba). Partnering with local clinics, we integrated their schedules, allowing for real-time booking which reduced average appointment wait times by 50%.

The Impact

  • Onboarded over 10,000 active users within six months of launch.
  • Achieved a 95% user satisfaction rate in post-launch surveys.

Subtleflow

Free business documents — invoices, contracts & proposals, drafted with AI

Subtleflow logo
subtleflow.xyz

The Challenge

Small businesses assemble the documents they send — invoices, quotations, contracts, proposals — from Word templates, one-off invoice generators and separate e-signature tools. The result is slow to produce, inconsistent with the brand, and invisible once sent: nobody knows whether a document was ever opened.

The Process & Solution

I designed and built Subtleflow as one workspace for all ten document types a business sends, with sequential numbering and reusable brand profiles. "Draft with AI" turns a one-line brief into a complete editable draft — line items, contract clauses, proposal scope — via structured AI output behind a Supabase Edge Function. Tokenized share links let clients review and sign on any device, statuses move from sent to viewed to accepted automatically, and every document exports as a print-ready branded PDF generated in the browser. Built with React 19, Vite, and Supabase (auth, Postgres with row-level security, Edge Functions).

The Impact

  • Completely free — unlimited documents, clients and brand profiles, with no tiers or trials.
  • E-signatures recorded with signer name, email and timestamp — no account needed on the client's side.
  • View tracking shows the moment a document is seen, and overdue invoices flag themselves.

Brightyield

Digitized loan operations for civil servants via IPPIS deductions

Brightyield logo
brightyield.co

Overview

Brightyield Golden Resources Limited is a finance firm in Abuja, Nigeria, specializing in loans to police officers and civil servants, leveraging the IPPIS infrastructure for direct deductions. I led initiatives to streamline operations and transform a loan process that was previously manual and prone to delays.

The Challenge

  • Extended processing times — loan approvals often took 7–10 days.
  • Manual data entry caused inaccuracies, increasing operational costs by ~25%.
  • The firm struggled to handle 30% year-over-year client growth.

The Solution

I proposed digitizing the loan workflow through a custom resource management tool integrated with existing CRM systems: automated eligibility checks, KPI dashboards for real-time tracking, and mobile-friendly interfaces for on-duty officers. The result: 20% improved operational efficiency and a 15% reduction in project delays.
