Republic Bank N.V.

Software Developer

Work Experience : 2009-Present
  • Contracted by the RBTT Bank (now Republic Bank (Suriname) N.V.) in Paramaribo, Suriname to rewrite an existing payment processing application that was written in CA-Clipper almost 10 years earlier. He was hired partly because of his past experience with programming in CA-Clipper and partly because he came highly recommended. In the process of rewriting the application, new functionalities were also added and lots of improvements were made. The purpose of the application is to process a daily stream of financial transactions being delivered to the bank in various formats from various sources (privately owned businesses, the government, etc.). After performing a number of checks on the data, the data is transformed into an internal format, and output files are generated that can be further processed at the RBTT headquarters in Trinidad. Various reports are automatically generated for internal checks, as well as letters and reports for
    clients.
  • The application is written based on a client-server model with multi-user functionality featuring configurable access restrictions per user or per group of users, and detailed logging of all user activity. The application also maintains a complete history of all processed transactions. Technical documentation for administrators and an online help system for users were delivered with the application.

GISsat N.V.

Software Engineer

Categories

Work Experience : 2007-2008
  • Contracted by N.V. GISsat to develop an application for the GLIS Project (Land registration and Land Information System). GLIS is a system that digitally displays parcels in Suriname and stores all relevant data about the parcels such as the area and the ownership.
  • When he joined the project the functional design for the application was already available as well as the data model. After a few meetings, he started with technical design and software engineering. The main purpose of the application is to maintain a database of applications for pieces of land. The whole application process, from the registration to the final approval and transfer of ownership can be managed. In addition, the application also automates certain functionalities such as merging parcels together and splitting parcels.
  • The application had to be built as an extension to ESRI ArcGIS and functioned within that environment based on a client-server model.

Intermodulair N.V.

Software Engineer

Work Experience : 2002-2004
  • Co-designed and developed a custom application for the Particuliere Ziektekosten Verzekering (PZS) (Health Insurance) department of Self Reliance N.V., one of the largest insurance companies in Suriname. I designed the complete software model for that integrated administrative software system for Self Reliance N.V. Based on a client-server architecture, this system includes a custom-developed applications server, several system management tools, and at least 5 client applications for several of the major departments in the company featuring tight security. I also did parts of the analysis for the functional requirements and co-designed the database. The system is capable of running both on Microsoft SQL Server and IBM DB2 without any modifications. Tools for security, authentication, user and group management, application rights, and policy management are also included.
  • The success of the PZS application was one of the important achievements that helped Intermodulair to get
    an even bigger project, arguably one of the most ambitious software development projects in Suriname up
    until that time, namely the development of an integrated software system for the whole company linking all departments together. After I left Intermodulair in 2004 development and maintenance were continued by other programmers at Intermodulair. This system is still being used today (July 2022).
