How we work
From first call to measurable outcomes.
Discover
We map goals, users, constraints, and risks in a focused discovery sprint so every decision after it is grounded.
Design
Architecture, UX, and a delivery roadmap you can hold us to — with clear milestones and a realistic budget.
Build
Two-week sprints with working demos, automated tests, and code reviews. You see progress, not status reports.
Launch & grow
We ship carefully, monitor what matters, and keep improving the product with you after go-live.
FAQ
Questions teams ask before working with us.
What kinds of projects does RayTec take on?
Custom web platforms, mobile apps, internal tools, AI-powered automation, cloud and infrastructure work, and security assessments. We are strongest where software, data, and operations meet.
Do you only work with companies in Semarang?
No. We are based in Semarang, Central Java, and work remotely with teams across Indonesia and abroad. On-site workshops are available when they help.
How do you price a project?
After a short discovery call we propose a fixed-scope phase or a dedicated team, with the budget and timeline written down. Our estimator on the contact page gives a first indication.
Can you take over or modernise an existing system?
Yes. We start with a technical audit, stabilise what is risky, and then modernise in steps so the business keeps running.
What happens after launch?
We offer maintenance, monitoring, and continuous improvement retainers, or a clean hand-over with documentation to your own team.
