Hi everyone — I'm a backend engineer with 3+ years building and shipping production backend systems, primarily in fintech and financial infrastructure.
Here's some of what I've built in production:

Fintech API (Moniexar) — Multi-domain system covering wallets, payments, crypto, eSIM, and KYC with 10+ live third-party integrations (Fireblocks, Paystack, Smile ID, Reloadly, Airalo, AWS S3, Firebase). Built with Node.js/TypeScript, PostgreSQL, Redis, and RabbitMQ.
Banking Simulator (BankSim) — NestJS service modelled on Finacle architecture. Implemented transfer idempotency, fee engine, ledger posting, the outbox pattern for reliable event delivery, daily limits, and full audit trail. Stack: NestJS · Prisma · PostgreSQL · RabbitMQ · Redis.
Credit & KYC Platform (Kredit Africa) — Two-service backend (Node.js + Django) handling loan origination, Paystack payment webhooks, fraud detection, and automated KYC pipelines integrating BVN/NIN verification, Azure Document Intelligence, and Google Document AI.
OCR Document Pipeline — Automated ingestion system using AWS Textract + OpenCV to convert unstructured documents into structured database records at scale.

I'm actively exploring new backend roles — particularly in fintech, banking infrastructure, or data-heavy platforms. Open to full-time (remote or onsite Lagos), contract work, and short-term projects.
If your team is hiring or you know of relevant opportunities, I'd appreciate the connection. 🙏
