About

Portrait of Ayodeji Adeniyi

I build products twice — first as a strategist, then as an engineer. I've shipped AI-powered products for African markets: a digital health platform for underserved communities, an ML-matched dating app for tech professionals, and booking infrastructure for interstate travel — all live and linked below.

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, with a tiny accessibility-focused JavaScript helper.

Waybl

Peer-to-peer delivery marketplace connecting Senders with Carriers

Waybl

Send it with someone already going

waybl.app ↗ · Public MVP in development

My Role

Product Manager — product strategy, end-to-end journey design, roadmap prioritization, stakeholder alignment and phased public-launch planning. 2026 – present.

The Problem

Sending parcels between cities can be expensive, slow and difficult to trust, while travellers already move along those routes with spare capacity. Waybl is building a marketplace that matches Senders with verified Carriers and manages the journey from request and payment through secure handover and delivery.

Product Decisions & Scope

  • Designed the full two-sided journey. Covered Sender and Carrier onboarding, identity verification, matching, booking-based messaging, secure four-digit handover codes, tracking and completion.
  • Reviewed the unhappy paths. Added missing flows for failed payments, trip changes, cancellations, no-shows, delayed or lost parcels, disputes and account recovery.
  • Clarified the money model. Defined a one-time Waybl fee and aligned deposits, refunds, Carrier earnings and withdrawals so customers and the team can see how money moves.
  • Turned the review into delivery work. Added 22 missing roadmap items and mapped dependencies across design, backend and frontend in Linear, keeping the launch focused on complete customer journeys.
  • Kept launch public. Reframed Phase 6 as a public MVP and added readiness checks for mobile use, security, payment recovery and support operations.

Current Status

The service foundation covers matching, journey tracking, secure handover, private messaging and safety checks. I am driving the remaining customer-facing journeys and launch-readiness work.

Àrà

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

Àrà logo
ara.ayodeji.xyz

My Role

Product Engineer — solo, end to end: positioning, brand, design system, copy, and every line of code. Independent studio, 2026 – present.

The Problem

Àrà (ah-RAH — Yorùbá for "wonders, the never-seen-before") exists because small businesses in Nigeria keep hearing they need AI but can't buy it. What's on offer is open-ended consulting, priced by the hour, with no guaranteed output — exactly the engagement shape a cash-conscious founder can't risk. The bet: productize the work into fixed-scope, fixed-price offers — an AI opportunity audit, a six-week MVP, an AI integration sprint, and an always-on design & build subscription.

Decisions & Tradeoffs

  • Fixed price over hourly. Removes the buyer's risk and forces honest scoping on my side. The tradeoff: I have to say no to vague briefs, and the audit exists precisely to turn vague briefs into buildable ones.
  • The site is the demo. Instead of claiming AI competence, the landing page embeds two working AI tools — "Audit my business" and "Spec my idea" — running server-side Gemini with structured, validated JSON output. The tradeoff: real inference costs and abuse surface, handled with rate limiting and server-side keys. The upside surprised me: prospects arrive at the booking call with a machine-drafted spec already in hand, so the tools double as lead qualification.
  • A design system from Nigerian textile traditions — Adire, Aso-oke, Uli linework, Benin coral beads — instead of the default SaaS gradient. Slower to build (nothing could be borrowed from a UI kit), but it makes the studio unmistakable, and the interactive Design Lab lets visitors play with the system itself.
  • Never lose a lead. The Supabase-backed booking flow falls back to a plain mailto link if anything fails. A broken API call should never cost a client.
  • Accessibility as a constraint, not a patch. Every animation honors reduced-motion preferences.

TechiesMatch

AI-powered dating for tech professionals, matched by ML

TechiesMatch logo
techies.love

My Role

Product Manager — contract role on a small founding team, Jan – Apr 2025.

The Challenge

The online dating market is saturated, but the team 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 — matches users rated as meaningfully better than swipe-based alternatives. I also designed and ran an A/B testing program on the onboarding flow, shipping the variant that measurably cut sign-up drop-off.

The Impact

  • Early cohorts returned at a markedly higher rate than the pre-ML baseline, validating the compatibility model.
  • ML-driven match recommendations became the app's most-used feature and the core of its retention loop.

HealthTrackNG

Offline-first digital health access for underserved communities

HealthTrackNG logo
healthtrack-ng-connect.vercel.app

My Role

Product Manager — independent build with clinic partners, Jul – Aug 2025.

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 for real-time booking, replacing hours of queueing with a confirmed appointment before leaving home.

The Impact

  • Adopted by patients across multiple partner clinics in its first months, with offline access driving usage in low-connectivity areas.
  • Post-launch surveys showed strong satisfaction, led by local-language support and shorter waits.

Subtleflow

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

Subtleflow logo
subtleflow.xyz

My Role

Designer & developer — independent solo build, 2025.

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

My Role

Business Manager, Operations & Business Development — full-time employer, Mar 2023 – Apr 2025.

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 that drove up operational costs and rework.
  • The firm was growing faster than its manual processes could absorb.

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: approvals moved from days toward hours, manual re-entry disappeared, and the firm absorbed its client growth without added headcount.
