About Anselme

With 15 years of experience, I leverage my senior expertise to serve startups, SMEs, and large corporations in designing high-performing, scalable, and optimized applications.

đź’ˇ Since the beginning of my freelance career, I have prioritizedhigh-impact missionswithin motivated teams where trust prevails. I have contributed to innovative and meaningful projects in various sectors:
  • 🩺 Wello (assistance for people with loss of autonomy)
  • 🎓 Internet Sans Crainte (raising awareness among young people about digital technology)
  • 🇫🇷 SNU (modernizing youth civic engagement)
🔎 My role is to support technical teams in implementing simple, effective, and maintainable solutions. A follower of KISS and YAGNI principles, I combine speed of execution with technical excellence.
I also have a solid product culture, which I use to bridge the gap between business needs, user requirements, and technical constraints. I appreciate environments where ideas can be challenged, specs refined, and meaningful solutions co-created.

đź”§ Expertise & Interventions
  • Supporting teams as a Tech Lead: technical management, software architecture, mentoring, and upskilling developers
  • Fullstack Javascript/Typescript Development (web & mobile) → "Keep it simple but significant".
  • Performance Optimization (loading time, scalability)
  • Continuous Integration & Deployment (CI/CD, automation)
  • Cloud & Containerization (Docker, Kubernetes, AWS)
  • Open source & technological watch (conferences, contributions)
  • I also integrate AI into my development processes to accelerate deliveries and reduce costs (Cursor, Bolt, Lovable, ...), while using my years of experience to properly frame it
