I have over 25 years' experience as a computer application developer. I am French-speaking, but I can work in English. I started programming with C and Delphi using C++ Builder, and now with RAD Studio 12. With this environment, I have developed several software programs, including: • GetSCol (school management) with the following modules: tuition payment; grade management and report card editing; timetable management, exercise book management; teacher course monitoring management. • CAMPAIE (payroll management) • Stockfacile (stock management) • Hospitalsoft (hospital management) taking into account the billing of medical procedures and patient biological test reports. • Etc.... All of this software was designed and deployed using various DBMS (database management systems) such as: Interbase, Firebird, Access, Informix, SQL Anywhere, MySQL, and PostgreSQL. My diverse knowledge of maintenance and computer networks is very useful to me during the software development and deployment phases. I have managed several projects from start to finish (data analysis, implementation in DBMS, development and deployment). I have been working remotely for two years as a non-contracted support staff member at Appzoola. I have participated in the development of several products using GitHub, Git, JavaScript, JSON, TMS Web, and HTML. I am also familiar with other languages such as Java. I have developed several websites using Drupal, PHP, HTML and MySQL. I am looking to join another development team for remote work. Please do not hesitate to contact me if such an opportunity arises, either with your company or elsewhere. I am actively seeking such an opportunity. I am available to work any schedule for 10 hours per day. Kind regards, Sosthene DIABANKANA Tel/WhatsApp: 237672807699 Email: [email protected]
