Scattered data
Excel, paper, WhatsApp, and separate files make searching and reporting slow.
WEB APPLICATIONS & INFORMATION SYSTEMS
Technology that makes work simpler.
I help businesses, organizations, and public services turn manual, scattered, or hard-to-monitor work into digital systems that fit real needs — without unnecessary complexity.

WorkflowSesuai
Not every problem needs a large application. What matters is usefulness.
YOU MAY BE EXPERIENCING THIS
Not just building an app. We start with the problem.
Technology should reduce work, not add complexity. Systems can be built gradually according to needs and budget.
Repeated work
Repeated data entry and reports can often be simplified.
Legacy application issues
An existing system may need fixes, migration, or new features.
Hard to monitor
The data exists, but it is not yet easy to turn into useful information.
SERVICES
Start with what matters most.
You do not have to build a large system immediately. Start with the part that saves the most time.
01
Custom Web Applications
Systems built around your workflow instead of forcing you into a rigid template.
- Administration & operations
- Dashboards & reports
- Database & access control
02
Data Digitization
Turn Excel, forms, or manual records into a more structured workflow.
- Data migration & cleanup
- Input & search forms
- Automated reports
03
Fixes & Maintenance
Support for existing applications that need fixes or adjustments.
- Bug fixes
- Feature additions
- Hosting, database & backup
04
Phased Development
With a limited budget, build by priority so technology investment stays measurable.
- Start with core features
- Expand later
- Technology based on need
WORKING PRINCIPLES
Simple, sensible, and not excessive.
Focus on real problems and workflows.
Features follow needs, not trends.
Budget is discussed according to scope.
Room for support and future development.

RAG + LLM
How it works in simple terms: The user asks a question. The system searches for relevant information from documents, databases, or a knowledge base by uploading PDF files. The retrieved information is provided to the LLM as context. The LLM generates an answer based on the retrieved information. In short, RAG = LLM + document search engine + answer generation based on retrieved documents.

HOW IT WORKS
You do not have to decide immediately.
The first conversation is for understanding the need. A proposal comes after the scope is clear.
01
Tell me the problem
Explain how the work is done today and what is most troublesome.
02
Map the workflow
We map the flow, data, users, and features that are actually needed.
03
Choose priorities
Start with the part that matters most when the need is broad.
04
Build & support
The system is developed, tested, and can grow step by step.
ABOUT SATUAPLIKASI
Long experience in web, databases, and information systems.
SatuAplikasi is built on application development experience since 2003. The focus is not chasing every trend, but using sensible technology to solve real needs.
START WITH A CONVERSATION
Have a need or problem you would like to discuss?
You do not need to know which application you need. Tell me about the work or the problem, and we can see whether a system, a fix, or a simpler solution makes sense.
No obligation to buy
The first conversation is for understanding the need and possible solutions. A proposal comes after the scope is clear.
