Резюме
Я розробник мобільних додатків з великим досвідом роботи з Android (4 роки) та Flutter (2 роки).
Останнім моїм досягненням є додаток PlantIn 🌱, унікальна платформа для любителів рослин, розроблена мною з нуля, що має 3,5 мільйона активних користувачів.

❗❗ Хочу попередити, що я детально вивчав платформу "Freelancehunt", протягом двох місяців шукаючи члена в команду на одному з проектів, де я працював раніше, та побачив, що тут є дуже багато розробників, які після проходження інтервью показали, що вони не є тими професіоналами, якими вони хочуть здаватися, хоча їх позиції в рейтингу були далеко не останніми 🙂 ❗❗
Спочатку свого шляху розробника і на сьогоднішній день я йду в ногу з часом використовуючи останні архітектурні підходи, технології та best practice, що пропонують розробники фреймворків, якими я користуюся.
Отже, щоб отримати дійсно якісне та професійне рішення, яке потім не треба буде переписувати багато разів, пропоную не гаяти час та починати нашу співпрацю 🤝
З радістю реалізую:
- нативний Android додаток з використанням Kotlin та Android SDK
- кросплатформний мобільний додаток android, iOS, web, desktop з використанням Dart та Flutter SDK
+
Мої навички не обмежуються лише мобільною розробкою. Я пропоную комплексне рішення, оскільки можу також проектувати та розробляти серверну частину додатків, використовуючи Node.js з TypeScript. Це дає можливість розробити систему будь-якої складності та задовольнити усі основні аспекти розробки будь-якого додатку!
