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

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.

It is very difficult to contact a person when he comes out of contact once a week. I’m a bad customer and I didn’t give the full TZ... but another freelancer managed the same task in 4 days!! And without any type of firewalls let your administrator himself understand, through the timware I won’t connect and so on.

Denis is a very experienced programmer, responsible for the performance of the assigned task, constantly in communication. The project was implemented at the highest level, taking into account my wishes, all to one.
The only point to pay attention to both him and the future customer is the deadlines for execution. They need to be kept more strictly and monitor the schedule of the work.

My personal overall freelancer rating is 10/10. I recommend to everyone.
