About Wanis

Symfony expert specializing in SaaS and business tools, I design robust applications with strong business logic (ERP, API, automation, AI).

Coming from École 42 (IT Architecture Expert), I work on highly complex projects, particularly ERPs (payroll, HR, commerce) requiring advanced business logic, regulatory constraints, and high demands in performance and maintainability.

I support my clients end-to-end, from design to production, with a focus on performance, scalability, and product impact, including the development of secure APIs and the creation of modern React interfaces.

I also integrate artificial intelligence solutions into applications (automated content generation, workflow optimization, internal tools), and I use these technologies from the design phase to accelerate development and improve product quality.

🔧 Main Stack:
Symfony 6/7 • PHP • REST API • React • TypeScript • PostgreSQL • Docker • CI/CD

🎯 What I can bring you:
• Custom SaaS and business tool development
• Robust and scalable backend architecture
• API design and optimization
• Integration of AI-based features
• Improvement of performance and maintainability

💡 Recent Projects:
• Payroll ERP: development of critical modules with complex business logic
• SaaS: design and development from scratch
• AI: automated content generation and workflow optimization

Accustomed to Agile environments, I quickly integrate into your teams and bring a product- and results-oriented approach.

Available for high-value-added freelance missions.
