Full-Stack Projects — Holberton School

Software Developer (Trainee)

ReactPythonFlaskMySQL

Context

Holberton School is an intensive, project-based full-stack program covering the entire software development lifecycle — from core algorithms to deployed applications.

Problem

  • The program required building complete full-stack applications in short cycles, with no predefined scaffolding frameworks.
  • Each project required designing both backend (Flask + MySQL) and frontend (React) architecture from scratch.
  • Unit and integration test coverage was required for every submission.

Solution

  • Built multiple full-stack projects using React for the frontend, Flask for the API and MySQL as the database.
  • Applied unit and integration testing on every project to ensure code quality and robustness.
  • Solved 100+ algorithms and data structures exercises, strengthening problem-solving fundamentals applied directly to application design.

Result

  • Software Development Certification.
  • Solid software engineering fundamentals applied directly in later professional projects.
