#1 Assemble with purpose
Right problem first.
Before we choose a framework, we find out what is actually broken. Then we use what already works — existing systems, open standards, proven tools — and build new parts only where nothing else fits.

Built from
what's here.
Built for
what's next.
Rakit Kala Teknologi is an Indonesian technology company. We take the parts you already have — your data, your tools, your people, your constraints — and assemble them into systems that keep working long after launch day.
#00 The approach
Software that
keeps working
- stack
- TypeScript and GoLang, chosen per problem. We tell you when what you already have is good enough.
- delivery
- Working software every 2 weeks, not slides.
- ownership
- Source, documentation and credentials are handed over to you.
We are an engineering team, not a template shop. We find out what is actually broken, reuse what already works, and build new parts only where nothing else fits. Then we hand over a system your own team can run.
Why we exist →How we build
Four rules
we build by
#2 Made for real needs
Useful past the demo.
A system is finished when the people using it on a Monday morning can rely on it, not when the presentation goes well. We judge our work by daily use.
#3 Built to adapt
Not married to a stack.
Tools change every few years. We choose technology for the problem in front of us, write code the next engineer can read, and keep your options open so changing direction never means starting over.
#4 Across eras
Built to outlast the project.
We document, we hand over, and you own your code and your data. If you never call us again, the system should still hold.
What we build
Systems,
products,
connections.
- 01
Custom systems
Internal tools, operations platforms and business software built around how your team really works, not how a template assumes it does.
- 02
Digital products
Web and mobile products, from first working version to the one customers pay for.
- 03
Integration
Connecting the tools you already pay for, so data is entered once and stays correct everywhere.
- 04
Technical advisory
Architecture reviews, code audits and an honest second opinion before you commit budget.
From survey to handover
How a project
ships
Survey
We map what you have: systems, data, people, budget, deadline. You get a written scope you could take to any vendor.
Select
We decide what to reuse, what to buy and what to build, and explain why in plain language.
Assemble
We build in short cycles and show working software every 2 weeks, not slides.
Hand over
Code, documentation, access and training go to you. Ongoing support is available, never a condition.
Questions
Asked
often
What does a project cost?
It depends on scope, so we price after the Survey. Most engagements start from Rp5.000.000,00 (~$300). The Survey itself is FREE.
How long does it take?
A focused system usually takes 4-8 weeks. You will see working software within the first 2 weeks.
Which technologies do you use?
Whatever fits the problem and your team. We will tell you when something you already have is good enough.
Who owns the code?
You do, once the project is paid. Source, documentation and credentials are handed over at the end.
Do you maintain systems after launch?
Yes, through an optional Maintenance Phase. You can also hand maintenance to your own team or another vendor; we will help with the transition.
Do you work with clients outside Indonesia?
Of course! We do work with clients outside Indonesia remotely.
