Senior Web Developer | 12 years of expertise
Do you need to develop a robust web application, or evolve an existing product towards greater stability and performance ?
I act as a senior web developer with 12 years of experience in demanding environments.
12 years of experience in high-constraint sectors
I have supported companies from various sectors:
- **Regulated Fintech**: KYC/KYB systems, AML/CFT compliance, banking integrations
- **Crypto**: Exchange platform, transactional API, security management
- **Cybersecurity**: Vulnerability monitoring, compliance management
- **Luxury, Music Industry, and Events**: Custom business platforms
This diversity allows me to quickly understand your business challenges, your regulatory or technical constraints, and to deliver pragmatic, production-oriented solutions.
What I bring concretely
- Design and maintenance of SaaS applications and business platforms
- Takeover of existing projects (refactoring, technical debt reduction)
- Performance and reliability optimizations
- Third-party integrations (payment, electronic signature, marketing...)
- Automations
My approach guarantees a professional and maintainable product: automated tests, code review, technical documentation, secure deployment. No quick fixes or surprises 6 months later.
Have a project to launch or secure? Contact me to discuss it.
