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
