Open to full-stack and AI engineering roles

Falola Olufemi Adedeji

I build production web and mobile products — and I'm moving that work into AI engineering.

Full-stack engineer with five years shipping user-facing products across fintech, edtech, and consumer SaaS. Frontend architecture in React, Next.js, and React Native; backend delivery in Node.js, NestJS, and Go. Now taking that into AI engineering, where a statistics degree is finally earning its keep.

AI-powered escrow, web and mobile

An escrow platform that uses AI-driven risk signals to protect both sides of a transaction.

Lead frontend for the platform end to end — secure transaction workflows, dispute and status tracking, and the user dashboards that sit on top of them. Also build and debug complex UI on the React Native app. Work directly with stakeholders and backend engineers to turn business rules into interfaces people can actually trust.

Multi-role school management dashboard

One dashboard serving three distinct audiences — administrators, teachers, and students.

Frontend lead: set development strategy, enforced performance and code-quality standards, and mentored three junior engineers. Spearheaded the core dashboard from wireframes to production, then reworked client-side state with Redux Toolkit and React Query to cut redundant fetching and render churn.

RevHero

Frontend Engineer — direct, then via RevStar Consulting

Jun 2025 — Present

Ground-up UI redesign and frontend rearchitecture

A revenue platform whose interface had outgrown its original structure.

Led a full UI redesign and rebuilt the frontend on React, Next.js, and TypeScript — replacing ad-hoc styling with a responsive design system that improved usability and accessibility. Partnered with product and UX to keep the visual direction anchored to user feedback, and drove consistency across product modules.

Data-plan purchasing with live payment flows

A consumer platform for buying mobile data, wired to payment gateways and third-party vendors.

Built the responsive web platform and integrated payment gateways alongside third-party data-vendor APIs. Focused on the unglamorous part that decides whether a payment product works: explicit transaction states, honest error surfaces, and feedback that tells the user exactly where their money is.

  • React
  • Redux Toolkit
  • Payment gateways

Code you can read

ledgerpay

Go · PostgreSQL · personal project

A payments API built around a double-entry ledger, to get the parts of money movement right that are invisible when they work and unrecoverable when they don't. Not production card rails — a study of the correctness patterns real payment systems depend on.

  • Double-entry ledger with overdraft protection enforced by row-level locking (SELECT … FOR UPDATE)
  • Idempotent charge retries keyed on client tokens, so a repeated request cannot double-charge
  • Transactional outbox for event delivery — no lost webhooks if the process dies mid-write
  • HMAC-SHA256 signed webhooks with retry and dead-letter handling
  • Runs as five services under Docker Compose, with CI on every push

03 — Current focus

Taking product engineering into AI.

I'd rather show you what I'm learning than imply I've already mastered it. This is what's actually on my desk right now.

  1. 01In progress

    AWS generative AI certification

    Working through the AWS generative AI certification track — foundation models, prompt engineering, retrieval-augmented generation, and the Bedrock service surface, alongside the AWS and Docker fundamentals that give it somewhere reliable to run.

  2. 02Active

    A statistics degree, pointed at AI systems

    My degree is in statistics, which turns out to be the useful half of this move. Sampling, inference, and experimental design are what separate a model that demos well from one that holds up — and they apply at the application layer, not just in training.

  3. 03Next

    Evaluation over impressions

    Working toward labelled evaluation sets, precision and recall reported per class, and prompt versions scored against each other rather than eyeballed. Calling a model is the easy half; proving its output is dependable is the part worth being good at.

  4. 04Active

    AI features in production products

    Applying that work where I already build — the AI-driven risk and fraud signals inside Finaive's escrow platform are the closest thing I have to a live proving ground.

04 — About

How I work.

I started in graphic design, moved into frontend because I wanted the things I designed to actually run, and ended up owning full-stack delivery. That route left me with a bias I still work from: the interface is where a product either earns trust or loses it.

Most of what I've shipped lives in domains where being wrong is expensive — escrow payments, school records, data purchases. So I care disproportionately about the parts nobody demos: explicit loading and error states, honest empty screens, and messages that tell a user where their money or their data went.

I've led a small frontend team, which mostly taught me that setting a readable standard and reviewing against it beats being the person who writes the most code. I'm now pointing all of that at AI engineering, because the interesting reliability problems have moved there.

My degree is in statistics, which sat quietly under the product work for years and has become the most useful thing I have for that move. The hard part of shipping AI isn't calling the model — it's knowing whether the output is actually good, which is a measurement problem before it is an engineering one.
