If I applied to your job - it means I'm interested and will commit 100% to the successful completion. I have only 5-star reviews because I carefully select what projects to work on and which people to work with, I won't work on any project. If you found me through the search and I accepted an invitation to your interview, then most probably you've already found the right candidate. I am in web-dev since 2010, starting from 2014 gained a lot of expertise in Symfony 2/3/4, Meteor, Next.js and React. My current technology stack, which I've been using since 2016, includes Next.js, Meteor, MongoDB and Blaze/React-Redux. Previously I've been working mostly on backend with Symfony2/3/4 (Doctrine, Sonata Admin, capifony, PHPUnit) on top of PHP 5.6/PHP7, a bit of AngularJS (with jQuery of course). I'm also using Git, Ansible, Composer, Varnish, Docker, RabbitMQ and ElasticSearch. Despite I've considered myself a backend developer all the time, because it didn't bring me much joy to work with Javascript, looks like I tend to turn into a full-stack developer. Prior to that I've been working with Phalcon, Zend Framework 1.12, CodeIgniter 2, php-resque, redis, LiquiBase, Jasmine. In 2012 and 2013 studied in Uni-Bonn for 2 semesters. During the year 2014 was employed at a startup in Munich. From 2015 to 2019 was working remotely for a Berlin-based company working on both client projects and inner startups. Since 2019 started active freelancing, attempting to build a proper team to work with.

Laravel is my favourite framework for creating elegant websites, multifunctional webapps and APIs of any kind. When it comes to high-performance async APIs, heavy data processing, AI, or machine learning I'm implementing FastAPI which is the best way to expose these as microservices. Example: Laravel handles the front-end and user system, while FastAPI provides endpoints for an ML model inference. I also create websites of any kind using Tailwind CSS, React or Alpine.js: to build frontend and familiar with almost all popular PHP-based CMS (eg. Wordpress, Opencart). Have over 15 years experience in JS and PHP development.
