Maintaining and evolving a large-scale Delphi-based enterprise application. Focus on architectural refactoring, modularization and performance optimization (3× improvement in CAD-related module). Extracted tightly coupled units into a dedicated DLL to improve separation of concerns and reduce dependencies. Implemented new features, resolved complex logic issues, and supported component migration (DevExpress → Almediadev).

Developed and redesigned HMI for an industrial optical belt scale (Weintek). Implemented and improved control logic on Siemens S7-1200 PLC. Added configurable Profibus and Modbus RTU parameters via HMI, integrated network settings (CP1243), and implemented production logging. Performed debugging and validation in an industrial environment. Tools: TIA Portal, SCL, LAD.

I corrected existed and write new ones SQL requests and packages for Oracle DB (to correct bank reports, or change report data parameters), corrected Delphi code to add additional reporting options and also developed new forms. I was directly involved in the development of bank printed forms for the "AIS IDO" system (automated information system for the fulfillment of monetary obligations) - I formed the output printed form and wrote SQL requests for its correct processing.

I developed a module for controlling invoice data entered into paper copies for the "shipment" program (the module allowed invoices to be sorted by many parameters and thus greatly facilitated the search for invoices and data verification for operators). I also developed modules for monitoring parameters of noise pollution, humidity levels, dust and fuel oil emissions in accordance with the requirements of the GOST for program "Measurement", also developed reports for these modules.
