Position: Senior PHP Developer
Category: PHP
English level: intermediate
Years of experience: 10

Perhaps my greatest achievement was the development of the main functionality for filling out PDF documents, according to US standards. The project is still running. I can tell you more in person.
I’m working in web development last 10 years, and met most part of PHP CMS and Frameworks, but best code what I’m ever contributed was with Laravel Framework (v7 - 9). Nevertheless, have few years of experience with YII (v1 – 2). In my work, I am using S and D from SOLID. Constantly check what my code is correspond to KISS. OOD is helps me to provide high reusable and simple to extend logic. 
Also have rich experience with different API’s – social networks, payment systems, third-party services and developed own with RestAPI for SPA. 
As experienced backend developer I am know, on my own experience, what often bottle neck of any web application is database. So meet requirements and best practices working with databases – is one of major purpose of competent design. With relational databases (MySQL, PostgreSQL) it is important properly use indexes, transactions and isolation levels. However, never bad idea to have replication or even sharding then load is planning to be high. 
Resolving issues with performance I am also have experience with No-SQL databases like Memcache, Redis or MongoDB – is data not relevant or need to have high-speed access is always a good idea. 
Server side is not a black box for me. Easily work with Linux and create Docker images for development purposes. 
Nevertheless, on this my expertise is not ending – I am also familiar with JavaScript. Two years as developer SPA with ReactJS, and never ending contributing code with Jquery. So meet fronted framework’s is not challenge for me. In addition, I have experience with server side JavaScript – NodeJS (ExpressJS + SocketIO) 
There is also a list of technologies, but I cannot say that my experience with them great – Elastic Search, for example.
I would be very interested in working in game development, or high-load systems. Of particular interest are technologies related to sockets and microservices.

I don't consider propositions from gambling or dating. And also quite tired of online commerce (shops, etc.) but still ready to discuss your project.
