Aji Prakoso, @jipraks

I build SaaS products, and make content about building them.

FreeKasir runs the till for thousands of small shops. Ceritopia reads picture books to children. AI Class hosts my courses. I build them under PT Jipraks Digital Indonesia, and share how each one is made.

Let's show your product doing real work.

I am a builder first, so I feature tools I can actually use in one of my products: hosting, cloud, AI APIs, dev tools, and anything a small team needs to ship.

Your product inside a real build I use your tool to ship part of an actual product, then show the build. Viewers see it working, not a script.
Dedicated video or review A YouTube video, a short for TikTok and Reels, or a Threads post written from my own hands-on test.
Series across four platforms One story cut for each platform, posted over a few weeks so the message lands more than once.
Longer partnership Your tool becomes part of my stack and shows up whenever it is the right fit for a build.
