About Toussaint

Backend developer specializing in Python/Django with 3 years of experience in designing high-performance REST APIs and scalable architectures.

I have designed and maintained backends for high-traffic mobile applications (10,000+ active users), particularly in the on-demand transport and cybersecurity sectors.

My expertise:
- Development of robust RESTful APIs (Django REST Framework)
- Performance optimization (SQL queries, Redis cache)
- Scalable backend architecture with Celery for asynchronous tasks
- Docker deployment, CI/CD, AWS
- Automated testing (TDD)

I am looking for freelance opportunities to apply my expertise to your backend projects: API redesign, performance optimization, new feature development, or MVP creation.
