Dejan D.

I build desktop applications, automation tools, and database solutions that replace manual work with reliable software. Most of my work is in C#/.NET, SQL (MSSQL and MySQL), and Python. Typical projects: Windows desktop applications in C#/.NET, plus Electron when a JavaScript-based desktop app fits better Database design, complex SQL queries, reporting, and data analysis Automation of repetitive business processes, scheduled jobs, and data imports/exports Python scripts for data processing, cleanup, and transformation Integration of desktop software with APIs, databases, and specialized hardware (including EZCAD3 SDK laser control) Extending and modernizing legacy systems (VB6, VB.NET, VBA, Office Add-Ins) without rebuilding everything Recent work includes a Customer Data Platform plugin for a healthcare company and advanced MySQL queries for data analysis. I've been programming since 2002. I'm a Microsoft Certified Professional and also a certified railway engineer. That background shapes how I work: understand the system, understand what can fail, and build something dependable. You can expect clear communication and realistic estimates. If I see a problem that could become expensive later, I'll tell you early. Based in Serbia, available 9 AM–6 PM CET, English and Serbian.
