Victor Koukin

I’m a software developer with deep experience supporting and modernizing large legacy systems, especially in enterprise environments. Since Aug 2022 at UPS (through Centific), I support UPS Capital products like COD/Cash on Delivery, BAI, and Reconciliation while driving upgrades through practical prototypes and refactoring.

I focus on secure, maintainable software and measurable outcomes. I implemented encryption (RSA 256), authentication (2 Factor), and authorization (Roles), documented architecture and technical specifications, investigated production issues via logs and debugging, and improved system efficiency by 80% through optimized critical code paths and database query changes.

Previously, as Systems Architect at iBasis, I designed and developed from scratch both Front End (Delphi) and Back End (Oracle packages) for SMS billing, including data structures, PL/SQL processing, ETL/loading Excel through temporary tables, and reporting (Flexcel). I’ve also led UI and database work in CAD/CAM and other internal legacy applications, balancing performance tuning with long-term maintainability.

I work comfortably in Agile Scrum, collaborating with product managers to prioritize features and deliver on tight deadlines. I also mentor junior engineers moving Delphi legacy systems to web-based solutions (Angular), helping establish coding standards, design patterns, and strong code review habits.
