FAJAR'S WORKBENCH / WHOAMI.YEFLABS.ID

I build things because I'm curious whether they'll work.

Software developer, automation tinkerer, self-hosting enjoyer, occasional product builder, and a dad who still thinks opening a terminal after everyone goes to sleep is a reasonable recreational activity.

NEED SOMETHING LIKE THIS?

I can help.

I also help people turn repetitive work, disconnected systems, and small technical problems into something that actually works.

AutomationToo much copy-paste, moving spreadsheets, reminders, reports, or repetitive work.

IntegrationTwo systems that should really be talking to each other.

Small softwareWhen Excel almost works and SaaS is overkill.

THE PERSON BEHIND THE WORKBENCH

More about me →

I'm Fajar, a software developer by profession and someone who genuinely enjoys figuring out how technology works.

Most projects here started with some variation of: “Eh, kalau begini bisa nggak ya?”

SOFTWARE · AUTOMATION · SELF-HOSTING · SECURITY · IOT · PRODUCT · AI · RANDOM RABBIT HOLES

WORK WITH ME

Manual, automated, or somewhere in between, the point is simple: the work gets done and the goal is reached.
