Разработчик Python

St. Petersburg · $1300 · 1.5 years of experience · Beginner/Elementary

Хочу быть профессиональным разработчиком на Python. Очень интересует машинное обучение и работа сданными. Картография! Начальник отдела программного обеспечения В учреждении более 100 сотрудников. ГКУ является заказчиком в сфере строительства автодорог и промышленно-гражданского строительства. Разработал и внедрил системы: учёта дорог (Delphi, MSSQL), совместно с отделом имущества, из разрозненных источников, восстановил информацию по дорогам, находящимся в оперативном управлении и создал базу данных; учёта оборудования (Delphi, MSSQL); учёта интернет-траффика (PHP, MySQL, JavaScript). Что привело к повышению эффективности работы отделов: имущества, бухгалтерии и программного обеспечения. В данный момент переношу базу дорог на платформу: Python 3 + Django 2.2 + Sqlite3 (PostgeSQL) . Прохожу обучение по темам: Machine Learning, нейронные сети и обработка данных. Создал векторную картографическую основу для создания карт-схем дорог общего пользования Забайкальского края (QGIS, PostgreSQL+PostGis). Периодически по запросам вышестоящего министерства и Администрации края формирую карты-схемы дорожной сети (строительство, эксплуатация, ремонт). Обучил навыкам работы в программе QGIS, отдел имущества и совместно с ними принял участие в подготовке картографической основы для программы «Дальневосточный гектар» на территории Забайкальского края. Задание было выполнено в раньше срока и без ошибок. Занимаюсь установкой и настройкой: ОС Windows 10(7), ОС Windows Server 2012, Centos6, ASPLinux; Web-серверов: Apache, IIS. На базе OC Linux мной были созданы интернет-шлюзы, что повысило безопасность локальной сети, обеспечило доступ к услугам интернет для всех сотрудников. Администрирование серверов. Мной была проведена доработка функционала сайта (переработаны с использованием CSS и JavaScript несколько разделов), что сделало информацию на сайте более наглядной и доступной. Периодическая работа с графикой и видео (обработка, монтаж).

Python, Django, PostgreSQL, MySQL, Linux, HTML, JavaScript

Разработал и внедрил системы: учёта дорог (Delphi, MSSQL), перенос на Python 3 + Django 2.2 + Sqlite3 (PostgeSQL) . Создал векторную картографическую основу для создания карт-схем дорог общего пользования (QGIS, PostgreSQL+PostGis).

Дружная команда единомышленников. Возможность участвовать в новом интересном проекте, получить знания о новых технологиях и подходах к решению задач.
