Oleg G.

I have no office work experience, for 6 years I have been doing freelance programming in php and js (including the server implementation of nodejs.)

The main work is the maintenance of internal combustion engines, and since they are now stuffed with electronics, I had to study micro controllers and programming. In my free time I create home automation systems (smart home), as well as systems for RC models (with FPV control). Now I am actively studying C++ to improve my skills in programming micro controllers.

I am also developing a fundamentally new electric generator with a colleague. The development includes the creation of electrical circuits, the production of printed circuit boards, the connection of various sensors, the writing of the controller code for the engine and the analysis of the received data. More details on the site Linear generator

During this time of free creativity were developed:

1. Technical library
Technology: PHP, MySQL
Repository: github
Link: Technical Library
Description: A library for techies that makes it possible to read/recognize PDF/DJVU books online page by page without downloading books to the user. Used console tesseract, ddjvu, gs commands to perform tasks.

2.Marine Career
Technology: PHP, MySQL
Repository: github
Reference: Marine Career CV
Description: The site is intended for sailors. Seafarers fill in their details on the site and can generate a CV to PDF using a variety of templates.

3. Marine Career Telegram Bot
Technologies: NodeJS, MySQL
Repository: github
Link: does not give a link to the telegram
Description: The bot is designed for sailors. Sailors in the bot indicate the positions on the ship and the types of ships that they are interested in. The bot scans websites on the Internet and makes mailings of vacancies in accordance with interests. Crewing companies can publish vacancies directly through the bot, and mailing is also based on interests.

4. Maptorium
Technologies: NodeJS, SQLite3
Repository: github
Link: no
Description: The program is designed to download tile and vector maps to the cache and then work with information from the cache without using the Internet. Due to the huge number of small files to work with, a way to store tiles in a database based on SQLite3 was developed. The program is written as a client / server and allows you to run the server on any computer on the Internet and manage the work and downloads through the browser. GPS tracking and route history, geometry editing are already available. Development continues.

5. Telegraf Bot Starter
Technology: NodeJS, MySQL
Repository: github
Link: no
Description: After the development of Marine Career Bot, a telegram bot template was created to speed up future development. The repository is open and available to everyone.

And also some other orders were completed for writing parsers, optimizing databases, etc. on the little things.
