What I'm looking for

I'm looking for a remote backend role where I can build and ship reliable Python APIs, payment integrations, and real-time systems while growing through production engineering work.

I built MatchDay, a production-deployed football ticket booking platform designed to address ticket scams and provide a trustworthy ticket source in Nigeria. I delivered the full stack end-to-end, from Flask REST APIs and PostgreSQL schema design to React, Render, Vercel, and GitHub Actions CI/CD deployments.

I integrated Paystack and Stripe payments with webhook verification and idempotency protection, wrote pytest coverage for duplicate payment events, and added real-time match updates through Flask-SocketIO. I also generated QR-code tickets and automated email delivery after successful payments.

I built AttendX to replace error-prone paper attendance for large university classes, including JWT authentication, role-based access, expiring attendance codes, automated CA-score calculations, Swagger/OpenAPI documentation, and automated tests for token and authorization security.
