Christopher Egbaaibon / senior backend engineer

I own the services that other people's money moves through.

Backend engineer, five years in. APIs and services on high-scale systems: a transaction platform for 50,000 users across Nigeria and Ghana, a fintech backend held at six nines, and the infrastructure under both. I lead the work end to end, from the architecture call to the thing still running six months later.

Systems, and what happened to them

01

Pandar transaction platform Fintech, crypto and cards

The core API converts crypto to Naira and redeems gift cards for 50,000 users across Nigeria and Ghana. I also built the wallet to bank transfer logic, which is the part that has to reconcile an internal wallet balance against a Nigerian bank account in real time, and the backend services provisioning virtual dollar cards.

Lingu Founder, agentic AI

A customer support platform that resolves tickets rather than summarising them: it reads the ticket, calls the customer's API, does the thing, and leaves an audit trail a human can check. Currently in pilot with early customers. I built it, so the architecture arguments in it are mine to defend.

TradeHub internal tool Real estate SaaS

Contract work on the client platform: an internal tool for bulk-uploading agent data and listing properties, then a search rebuild on Typesense because the existing lookup was the slowest thing in the product.

Search response time fell by roughly 99.9% after the move to Typesense.

SaveCircle SaaS platform

A collaborative savings platform where a group pools money and members take the pot in turn. I am building the MVP backend from the schema up: data model, API surface, and the AWS infrastructure and storage underneath as the product grows.

FroWork and Yeve Marketplace and events

Two products at Frolancer. FroWork is a freelance platform for Africa, built in TypeScript and NestJS. Yeve is an event platform, where I built the backend for ticket sales, attendee management and third-party integrations.

Yeve ticket sales grew 40% in year one. Separately, as a Hivend ambassador I helped grow FroWork's freelancer base and supported $30,000 in platform transactions inside the first three months.

MO Group platform rebuild Lead developer

Led a cross-functional team through a full platform rebuild, then directed a redesign of the payment system. This is where I learned that leading a rebuild is mostly sequencing and saying no, not architecture.

Rebuild: 30% higher user satisfaction, 20% better system performance. Payment redesign: 30% fewer payment errors, 20% more successful transactions.

Mbag Microfinance infrastructure DevOps

No product surface, all pipeline. Software infrastructure, internal tools and asset storage on AWS, with microservice deployments automated through GitHub Actions and Terraform so a release stopped being a manual checklist.

DolphJS Open source

A TypeScript backend framework I co-authored, aimed at developer productivity on enterprise and small projects alike. Maintaining something in public is the fastest way to find out which of your API decisions were actually opinions.

How the work actually goes

01

Own an API end to end

Contract first, then the service behind it, then the thing that pages you when it breaks.

  • REST design and documentation
  • Schema and query optimisation
  • Testing and monitoring before launch
02

Keep it up

Six nines is not a slogan, it is a set of boring decisions made early and kept.

  • Reconciliation between systems of record
  • Deployment automation, Terraform and Actions
  • Reducing technical debt on purpose
03

Lead the piece of work

I have run a cross-functional rebuild and a payment redesign. Both were mostly sequencing.

  • Architecture decisions with a written reason
  • Code review and mentorship
  • Talking to people who do not write code

Tell me what breaks and when.

A useful first message says what the system does, where it is falling over or where it is going next, and the date you are working to. I will tell you whether I am the right engineer for it before I tell you anything else.
