What's the story behind your product?

Reactive Resume's answer

Back in my university days, I designed a really cool dark mode resume (link on my website) using Figma and I had a line of friends and strangers asking me to design their resume for them.

While I could have charged everyone a hefty sum and retired even before I began, I decided to build the first version of Reactive Resume in 2019. Since then, it's gone through multiple iterations as I've learned a lot of better coding practices over the years.

At the time of writing, Reactive Resume is probably one of the only handful of resume builders out there available to the world for free and without an annoying paywall at the end. While being free is often associated with software that's not of good quality, I strive to prove them wrong and build a product that people love using and are benefitted by it.

My dream has always been to build something that at least a handful people use on a daily basis, and I'm extremely proud to say that Reactive Resume, over it's years of development, has helped over half a million people build their resume, and I hope it only increases from here and reaches more people who are in need of a good resume to kickstart their career.

Diffyn's answer:

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
