Syntra

Role: Full Stack Developer, InLustro
Timeline: March to May 2025
What I owned: Interface design, React build, backend and data layer
Built with: React · PostgreSQL · Interface design

The problem

Learners were abandoning tests partway through. The content was not the issue — the interface was losing them.

What I did

Designed and built an interactive test interface with a timer and question tracking, supporting 10+ concurrent users.
Rebuilt the navigation between questions, which reduced drop-off by 20%.
Built 10+ reusable React components, cutting development time roughly 30%.
Designed the login, signup and dashboard interfaces that carry the core flow.
Integrated PostgreSQL and improved backend efficiency and maintainability.

Outcome

Drop-off down 20%. Development time on new screens down roughly 30% once the component set existed.
