About Youssef
Senior Software Engineer
Sousse, Tunisia - 6:04 pm local time
I’m a Senior Software Developer with hands-on experience building and leading multi-tenant SaaS platforms. I specialize in full stack JavaScript development (MERN stack), backend architecture with NestJS, and advanced integrations including WhatsApp (Meta API) and AI-powered workflows.
Core Expertise:
• Full Stack Development (Next.js, React, Node.js, NestJS)
• SaaS Architecture & Multi-Tenant Systems
• WhatsApp Business API & Meta Integrations (webhooks, messaging flows, automation)
• REST APIs & Scalable Backend Design
• PostgreSQL & MongoDB (schema design, optimization, migrations)
• AI-driven features & automation workflows
• Vercel deployment & cloud hosting
• CI/CD pipelines, Docker, production optimization
What makes me different:
I don’t just write code, I design systems that scale.
I focus on clean architecture, maintainable code, and performance from day one.
I understand business logic, edge cases, and real-world production constraints.
I’ve built:
Multi-tenant SaaS platforms with role-based access control
WhatsApp-based automation systems integrated with Meta APIs
AI-assisted applications and chat-based workflows
Real-time systems using WebSockets
Performance-optimized backend systems with advanced database indexing
I’m comfortable owning features end-to-end: Planning → Architecture → Development → Deployment → Monitoring
If you're looking for a reliable Full Stack Developer who understands SaaS products, WhatsApp integrations, and scalable backend systems let’s talk.
Steps for completing your project
After purchasing the project, send requirements so Youssef can start the project.
Delivery time starts when Youssef receives requirements from you.
Youssef works on your project following the steps below.
Revisions may occur after the delivery date.
Meta App & WhatsApp Cloud API Setup
I configure your Meta Developer App and WhatsApp Business Account. I generate permanent system tokens and verify your phone number to ensure a stable connection between Meta’s infrastructure and your environment before coding begins.
Webhook Development & Logic Integration
I build the backend logic (Node.js/NestJS) to handle real-time events. This includes setting up secure webhook endpoints to process incoming messages, delivery statuses, and automated replies, ensuring data flows correctly to your CRM or SaaS.
