@jeffreyjacob
Backend Engineer at Zero to Zenith building Django APIs and Stripe subscription workflows.
NigeriaWhat I'm looking for
At Zero to Zenith, I develop Django REST Framework and PostgreSQL APIs for React applications, including Stripe payment and subscription workflows.
At Accolade Tech, I developed and maintained backend systems for a workforce management platform using Node.js, TypeScript, Express.js, Apollo GraphQL, MongoDB, Redis, and BullMQ. I implemented APIs and background jobs for workforce workflows, reporting, and subscriptions.
I integrated Stripe subscriptions and webhooks, adding retry and recovery mechanisms to support reliable event processing. I also applied Redis caching, database indexes, transactions, and concurrency controls to backend workflows.
In my projects, I designed payment and scheduling backends, including a double-entry-style ledger for WalletWave and concurrency-safe appointment availability for MedDesk. I'm focused on backend architecture, distributed systems, payment infrastructure, and fintech.
