Back to original languageAbout Jeson
Are you a startup or SME in software publishing and your web application suffers from slowness, growing technical debt, or scalability issues?
Read on 👇
If you are facing the following problems:
❌ Users complaining about responsiveness or loading times.
❌ A codebase that has become complex, difficult to maintain, and lacks automated tests.
❌ Skyrocketing infrastructure costs (Cloud/Servers) without notable improvement.
👉 Then you are in the right profile.
For 9 years, I have been helping software publishers design robust architectures and optimize the performance of their web applications.
By combining Software Craftsmanship (TDD, Clean Code) and modern architectures (Hexagonal, Microservices), I transform heavy systems into fluid and scalable applications.
I have notably optimized the architectures and fluidity of complex applications for clients such as Vinci Autoroutes, Ecocert, and Olea Médical (Canon Group).
✅ The results for your business:
✔ A tailor-made architectural and performance audit.
✔ A fluid, responsive application ready for load increases.
✔ Reduction of your technical debt and establishment of sustainable testing practices.
✔ Upskilling of your internal teams on best development practices.
⚙️ How do I work?
🔎 Diagnosis: Comprehensive audit of architecture, code, and performance.
🛠️ Implementation: Refactoring, implementation of appropriate patterns, and test suites.
📅 Follow-up: Support for your teams to sustain productivity gains.
🎁 As a bonus for my clients:
📄 Detailed report of solutions used.
📘 Deliverable of best practices (Clean Code, TDD) adapted to your context.
🤝 1 month of follow-up included after the intervention.
