About

Main bio

I'm Yusup a solo founder in Indonesia who builds eksis.io and apps people actually use.

I build and run three products on my own. The one I would like you to see first is eksis.io: it lets you publish, reply, and automate every social account from one place, with an AI assistant and an API and MCP server for your own tools.

Meowslim is an Android app for reading the Quran, prayer times, and keeping track of ibadah. Psikotes Kerja helps job seekers practice psychometric tests, with 491 questions and an explanation for every answer.

Before going solo I spent 5+ years as a fullstack and AI engineer: AI features for Japanese clients at Corevice, and the approval, payroll, and reporting system a mining and construction group runs on.

Based in Indonesia, working on WIB (UTC+7).

All three products are built and run by me, alone.
