System information






iSabaya is the software house specialized in developing quality information systems. The quality in our software is the product of our talented and experienced professionals and the emphasis on software design. Information systems are usually more complex than construction of high-rise buildings, good software design is most crucial to the success of such information systems. Good software designs are created by skillful and experience software architects. Our software architect (and analyst), Dr. Supoj Sutanthavibul earned his Ph.D. in Computer Science in 1991 from The University of Texas at Austin, Texas, USA. He has more than 35 years in both academic and real-world design and development experience. He has also taught many graduate-level courses including Object-oriented Analysis and Design, Database Management Systems, Operating Systems, Strategic Information System Planning, IT Governance. He is highly proficient in both BPMN (Business Process Model and Notation) and UML (Unified Modeling Language), the de facto and very powerful standard tools for capturing requirements and object-oriented design.

iSabaya has also created the proven object-oriented frameworks of reusable business classes that help us shortening the development time while improving the quality of information systems we’ve built. These frameworks are designed and developed by Dr. Supoj along with associated ORM (object to relational database mappings) that eases the change of relational data repository from one vendor to another.

Listed below are some of our works.

  • PromptPay systems for a Thai Bank (PromptPay is an integrated set of national electronic financial transaction service using citizen identity number and/or mobile phone numbers initiated by the Thai government in 2015) using C#, ASP.Net MVC, NHibernate, Oracle 11g
    • PromptPay ID/Phone numbers Registration web-based system
    • PromptPay Registration SOAP-based web services
    • PromptPay Registration gateway to the centralized PromptPay system of the National ITMX using REST (Representational State Transfer)
    • PromptPay Fund Transfer SOAP-based web services
    • PromptPay Fund Transfer gateway to the centralized PromptPay system of the National ITMX using ISO 8583 message format and TCP/IP sockets
  • Project Risk Assessment (web-based) system for the Bureau of Budgeting, the Office of the Prime Minister using C#, ASP.Net MVC, NHibernate, Microsoft SQL Server 2012
