Senior🎓
Top SchoolГрабчук Віталій is a seasoned Delphi software engineer with 11+ years building advanced GUI applications, custom controls and low-level painting (GDI/GDI+, image processing) alongside robust PostgreSQL-backed middleware and tooling. He has deep hands-on experience across Delphi 5–10 Berlin, Lazarus and Free Pascal, and previously developed UI editors, hardware-control components and licensing systems for industrial automation at ELEKS. A pragmatic freelancer since 2016, he combines legacy Delphi expertise with modern database practices and a knack for shipping maintainable, high-quality code. His open-source contributions include substantive back-end improvements to well-known projects like TortoiseGit—enhancing changelist management and compare functionality—and maintenance and bug-fix work on CnPack IDE Wizards, reflecting focus on code quality and developer tooling. Notably, he often implements both high-level UX features and the low-level painting or performance fixes that make graphics-heavy Windows apps feel native.
