Hi! I’m Nikolay Ruban — a mathematician with a passion for solving real-world problems through code. I thrive at the intersection of logic, creativity, and technology, and I love building solutions that make life easier (and sometimes a bit more fun!).
- Author of Two Programming Books: Wrote two books on competitive programming problem-solving, available at the Vernadsky National Library. These books provide detailed analysis of Olympiad-level algorithmic challenges.
- Mileage Tracking Database: Developed a Delphi-based system to monitor rolling stock mileage, ensuring timely routine maintenance and major repairs.
- Diploma Appendix Automation: Built an application (Delphi, Access) for generating templates—automating the process of filling out diploma appendices for specialists.
- Exam Ticket Generator: Created LaTeX applications to automatically generate randomized exam ticket sets, streamlining exam preparation.
- LeetCode Tracker & Code Generator: Parses the user profile, extracting a list of solved problems. Creates a structured database of solutions (in the form of folders with files).
I bring analytical precision, a love for clean code, and a dash of fun to every project I take on. Let’s build something great together!
