Hi, I’m Jufianto.
The engineer behind Sevtee.
I have been building software since 2016, starting with PHP for small businesses and schools and moving into Go for backend systems. I led a backend team on hospital systems and BPJS integrations, and since 2022 I have worked on open banking integrations at Brankas. Sevtee brings that experience to projects where practical engineering makes a difference.
You work directly with me, from understanding the problem to building and handing over the solution.

One illustrative project, from the first conversation to handover.
Understand & scope
Talk through the problem, agree on priorities, and define a useful first release. I quote that release as a fixed scope, split into milestones.
