Hi, I've been developing web applications for more than 9 years, starting back in 2013 with custom PHP/MySQL, no framework project, switching my focus onto ZF1 in 2013-2014 and now focusing on frameworks like Laravel and symfony. I've had a chance to work with the following PHP frameworks: ✅ symfony (2.x-6.x) ✅ Laravel (4-10) ✅ microframeworks like Slim, Lumen I'm using the following standards/recommendations/technologies in my daily work: ✅ SOLID principles ✅ PSR recommendations ✅ TDD - always trying to reach 100% coverage of my code ✅ RESTful, GraphQL APIs I'm used to working in agile environment, combining Kanban and SCRUM aspects in the development process. Recently I realised a good developer has to focus on the client's business goals and better communication. These skills are much harder to master than learning a new framework. As for the tech stack, here are some of the technologies I've mastered so far: ✅ AWS (EC2 with autoscaling, RDS, S3, SES, SQS, SNS, Route53, CloudFront, Lambda etc) ✅ PHP 5.x, 7.x, 8.x ✅ RFC 2616, knowing HTTP protocol inside-out ✅ composer Here is the tools I'm using in my local setup: ✅ Ubuntu LTS ✅ PHPStorm ✅ git ✅ slаck and Skypе for communication ✅ docker, docker-compose I've been working on long term projects and would like to continue doing so. Let's start with a free trial task - no cost and no obligations. We'll get to know each other and I can convince you in my skills. Let's have a skypе call discussing your project and me completing a free test task to show my skills!
