Devdex

A structured project showcase platform where developers and designers present work using the PSAT (Problem–Solution–Approach–Technologies) framework.

---

Problem Statement

Most portfolio platforms focus on what was built rather than why and how. This makes it difficult for recruiters, collaborators, and learners to evaluate real problem-solving ability.

---

Solution

This platform introduces a standardized PSAT format that structures project presentation into:

• Problem
• Solution
• Approach
• Technologies

This makes projects easier to understand, evaluate, and compare across users.
