Fee-calculation performance on a high-volume public-sector platform
Fee calculation ran for tens of seconds on the heaviest records and blocked the UI. Measured 3.4x to 15.4x faster.

Bogdan did a simply fantastic job. He was given half-finished code and turned it into a world-class product. He worked well with challenging input from a variety of sources, and often anticipated client requirements before they were noted by the client. I would have no hesitation in recommending Bogdan.
Bogdan converted an old DOS program with multiple databases into a Windows version for me. His work was excellent. The program is easy to use and is the most user-friendly of several similar programs. When we hit a snag, he usually knew of a third party that had just the interface we needed. It shipped with very few bugs - I have been selling it for years.
Bogdan is a wizard at what he does. He combines technical expertise with the ability to understand and interpret requirements to deliver first-class software. He never fails to add something that was never expected but turns out to be vital. We sent him an old MS Access application that several developers had worked on for over five years; he navigated a lot of poorly written code to quickly find where improvements were needed. I highly recommend Bogdan for any size project.
