Data to View Tool โ End-to-End Build to Live ๐
Breaking My Own Boundary
For years, Iโve designed complex systems โ but always stopped at the โhandoffโ stage. This time, I wanted to go beyond mockups and see how far I could take an idea on my own.
So I set myself a challenge: design, build, and launch a live tool โ solo โ in one week.
The Spark
If youโve ever opened a JSON file, you know the pain โ walls of nested data that make zero sense unless youโre an engineer.
As designers, we constantly deal with APIs, yet we rarely see what weโre designing for. Every project requires multiple dev syncs just to understand what data powers which UI element.
So I decided to fix that.
The Idea
A simple but surprisingly powerful tool:
Drop in a JSON file โ Instantly visualise it as a clean, structured table or card.
No setup, no code, no developer needed.
Perfect for designers, PMs, or anyone who wants to understand data quickly without diving into code.
The Build
Design: Started in Figma โ minimal, clean, and focused purely on usability.
Code: Used Cursor, my new favourite AI-powered coding partner. It helped me translate design components into React in hours, not days.
Launch: Deployed to Vercel, fully live, fully functional.
From blank canvas to public link โ one week.

The Outcome
This tiny tool solves a real problem:
It saves hours of back-and-forth between design and dev, speeds up data understanding, and brings non-technical teammates into the conversation.
Itโs not just a JSON viewer โ itโs a bridge between creativity and logic.

Iโd love to hear your thoughts, ideas, or wild use cases โ this is my first live mini product, and Iโm just getting started.
Why It Matters to me
For me, this marks a shift:
Iโm no longer just designing products โ Iโm building them.
With AI tools like Cursor, the gap between imagination and execution is shrinking fast.
And this is just the beginning. ๐
