CV
Started programming when it wasn't mainstream yet. Moreover, when most people saw a computer only on TV, and phones still had discs and wires. I taught my computer science teacher how to program, and the professors at the university kicked me out of lectures because I corrected their mistakes out loud
Crazy experience in programming business applications
My programs work at enterprises from self-employed to corporations with several thousand employees (most corporate systems are under DNA)
Any relational and noSQL databases
I love difficult tasks and new challenges. There are no tasks that cannot be solved, there are only time and budget constraints
All my programs have a lifetime guarantee - any error is corrected without any time-limits

Carrying the car
Хочу висловити щиру подяку Денису Шаповаленку за видатну роботу над розробкою програми завантаження автомобілів для нашого підприємства. Завдання, з яким ми звернулися до Дениса, було вкрай складним і вимогливим, і він впорався з ним на найвищому рівні.
Одним з основних викликів був великий асортимент типорозмірів нашої продукції, а також нестандартні розміри як продукції, так і піддонів. Денис продемонстрував глибоке розуміння наших потреб і ефективно впровадив гнучку систему, здатну ефективно обробляти різноманітність розмірів і форм.
Особливу увагу приділили вимогам щодо завантаження автомобілів з урахуванням навантаження по осях і видів транспортних засобів. Денис не тільки розробив функціональність, що відповідає цим вимогам, а й надав нам інтуїтивно зрозумілий інтерфейс, що дає змогу нашим співробітникам ефективно використовувати програму без додаткового навчання.
Крім того, хочу відзначити високий професіоналізм і відповідальність Дениса. Він не тільки дотримувався термінів, а й був готовий до оперативного вирішення питань і складнощів, що виникали в процесі роботи.
Співпраця з Денисом Шаповаленком принесла нашій компанії значні переваги в ефективності логістичних процесів. Ми впевнені, що його талант і професіоналізм можуть бути корисними для будь-якого проєкту, що вимагає високого рівня компетенції в галузі програмування.
Завдяки Денису наше підприємство тепер може з легкістю керувати складною логістикою та оптимізувати завантаження автомобілів, що призвело до поліпшення нашої загальної продуктивності.
