Hi there! I am Anton and I`ve been working as PHP software engineer for 2+ years. My coding languages stack is PHP, JS (TS), and obviously HTML and CSS. If we talk about DB, I am actually knowledgeable in MySQL and SQL databases in general. I usually code in Laravel or native PHP. If we talk about JavaScript, I`m familiar and obsessed with VueJS. During the period of time mentioned above I`ve experienced quite many different cases and projects, just like: SPA - sportschool management system built on top of multitenancy architecture (Laravel + Vue) EDI-factory (Native PHP + Docker) Crypto-project improvement (Laravel) Small-medium scaled E-commerce projects (Laravel, Docker) And so on :D I also have fluent knowledge of English and Ukrainian languages (meaning, both speaking and writing skills). Basically, no matter what kind of stuff you need - from small script to large-scaled web application (MPA or SPA) - I am willing to help you with implementing your needs and ideas in real life

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.
