👋 Flavien (rivon0507)

M2 (Bac+5) Software Engineering & Database — ENI Fianarantsoa
💻 Backend-focused engineer building with Java & Spring Boot
🌍 Madagascar

🧠 Engineering Focus

I build backend systems with emphasis on:

  • 🔐 Authentication & authorization design (JWT, OAuth2, token lifecycles)
  • 🏗️ Clean architecture & layered design
  • 🗃️ Data modeling & transactional integrity
  • ⚙️ REST API design with proper validation and security boundaries
  • 🧩 Algorithmic thinking & structured problem solving

I care about correctness, clarity, and long-term maintainability.

Currently:

  • 📚 Deepening my understanding of Spring fundamentals (beyond auto-configuration)
  • 🌱 Learning Angular with focus on architecture and state flow
  • ⚛️ Building occasional React side projects (collaborative experiments)
  • 🇯🇵 Studying Japanese for fun

🛠 Tech Stack

🎯 Direction

My goal is to become a backend engineer capable of:

  • Modeling data with clear ownership and boundaries
  • Making architectural decisions deliberately, not accidentally
  • Understanding what frameworks abstract — and when to bypass them
