You will get an expert third-party API integration for your backend
Project details
Are you struggling to connect a third-party API to your application? Do you need to integrate Stripe payments, OpenAI features, or sync data with an external REST/GraphQL service?
I am a Senior Backend Engineer (Go, Node.js, TypeScript) and I specialize in building rock-solid, secure, and fast API integrations. I don't just "make it work"—I ensure it handles rate limits, errors, and webhooks properly so your app doesn't crash in production.
What I can integrate for you:
• Payment Gateways (Stripe, PayPal)
• AI Models (OpenAI, Claude, Gemini)
• Communication (Twilio, SendGrid, Mailchimp)
• CRM & Tools (HubSpot, Salesforce, Google APIs)
• Custom REST or GraphQL APIs
Why work with me?
I write clean, typed, and well-documented code. Give me the API documentation and your repository, and I will handle the rest without needing hand-holding.
Note: Please send me a message with the API documentation link before placing an order so we can pick the right tier!

About Abdou
Go (Golang) & Node.js Backend API Expert | React & TypeScript
Dakar, Senegal - 10:09 pm local time
Whether you need to integrate a complex payment gateway, fix a critical database bottleneck (PostgreSQL/SQLite), or build a lightweight framework from scratch, I can deliver clean, type-safe, and scalable code.
As a Core Contributor at 01edu and the creator of open-source Go tools like 'Octopus' and 'Wave-pool', I don't just use frameworks—I understand how they work under the hood.
🔥 My core expertise:
- Backend: Go (Golang), Node.js (Express/Deno/Bun), TypeScript.
- APIs: RESTful, GraphQL, Webhooks, 3rd-party integrations (Stripe, messaging, etc.).
- Frontend: React, Next.js, Flutter.
- Infrastructure: Docker, Linux, PostgreSQL, Redis.
🌍 Why work with me?
- Perfect overlap with European (CET) business hours and US East Coast mornings.
- Native French and Fluent English (I adapt to your team's culture).
- Async-first mindset: I don't need hand-holding. Give me the requirements, and I'll deliver the PR.
Send me a quick message with your current tech stack or your API issue, and I'll tell you honestly if I'm the right developer for the job. Let's build something solid.
