The studio

A small studio.
A direct connection.

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.

How we’ll work together

1
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.
2
Build & review
Work milestone by milestone, with regular demos and room for feedback along the way.
3
Launch & hand over
Deploy to your own hosting and hand over the source code and documentation. Ongoing improvements and support are hourly or on a retainer.

Have something in mind?

Let’s make it work.
