I will build API integrations, webhooks and oauth login for your app
Mohamed A
About this gig
I'm a senior full stack developer who builds the unglamorous but critical plumbing that keeps SaaS apps in sync with the outside world: webhooks and OAuth integrations.
This gig is based on a production-grade billing backend where Stripe webhooks drive real business logic (subscriptions, invoices, dunning) with proper signature verification, idempotency, and retry handling. I bring that same rigor to whatever providers you need to connect.
What you get:
Signature-verified webhook endpoints (Stripe, GitHub, Shopify, custom providers, etc.)
OAuth 2.0 flows with token storage and automatic refresh
Retry queues so a dropped delivery never means lost data
An audit log of every event received and processed
Clean error handling so failures are visible, not silent
I can integrate with virtually any REST or webhook-based API. Message me with the providers you need connected and I'll confirm scope before you order.

Languages
French, English
Senior full stack developer with 8+ years building production systems for banking, insurance, and telecom companies. ENSIAS graduate (2017). I work across the stack: React/TypeScript, Node.js/NestJS, PostgreSQL, Redis, and Docker. I also maintain pre-built, production-quality systems (Stripe billing, an AI chatbot grounded in your docs, a real-time dashboard, and a webhook/OAuth hub) I can hand over and customize, saving you weeks versus starting from scratch. I care about the details that separate a demo from production: race conditions, retries, audit trails, and clear error handling.
