Freelancer profile translated to English.
Back to original languageAbout Khalil
I intervene on critical systems when production becomes unstable, performance drops, or teams can no longer deliver effectively.
With over 12 years of experience, I support companies (SaaS, fintech, web platforms) with high-impact issues:
• Production stabilization (critical bugs, errors, technical debt)
• Implementation and reliability of CI/CD
• Infrastructure and performance optimization
• Taking over complex or struggling projects
• Application scaling (Symfony, Node, .NET, React)
I combine backend, frontend, and DevOps expertise to intervene quickly and effectively where multiple profiles are usually needed.
Main Stack:
PHP (Symfony), Node.js, .NET, React, Docker, CI/CD (GitLab CI), PostgreSQL, Azure
Approach:
Quick Audit → Action Plan → Execution → Measurable Results
Intervention Examples:
• Stabilization of critical applications in the public sector (health)
• Implementation of robust CI/CD pipelines
• Architecture redesign (DDD, Hexagonal, CQRS)
• Coaching and skill development for technical teams
Available for high-impact missions in France and Europe (remote or hybrid).
