Hello,
my name is Jakub

My job is mainly optimize existing algorithms and new features development for multiple projects, i.e. worldwide most visited livechat service - livejasmin.com.

Attending ice hockey events (NHL, TELH, International...) and gathering of various data for statistics purposes.

Livesport company is the world's leader in sports scores delivery. The company created new team in Brno to build own OTT platform. Project was divided to several phases, phase 1 (integration of video streaming into FlashScore app) is already finished and available in the Czech Republic. I worked in a team of five (3 seniors, 2 juniors) and because of lack of people we took care of the whole app cycle. We created high available REST API in Symfony 4/5, PHP 7.4/8 and MariaDB/PostgreSQL. Production run in Kubernetes in GCP, dev version runs in our custom K8S cluster, which I co-built. I also co-operated on app architecture and security design. As a team-leader it was my duty to plan SCRUM sprints and meetings and take responsibility for continuous code delivery. Whole codebase was written using TDD (we had got unit, functional and integration tests), following the Object calisthenics principles and SOLID. Before I left the company I started working on standalone OTT platform, where we used Event Sourcing pattern, combined with CQRS.

oXyShop is one of the e-commerce leaders in the Czech Republic. In last 10+ years in market the company have delivered and maintains over a hundred customized e-shops, especially in the Czech Republic. My everyday routine consisted from company's e-commerce solution maintenance, developing new functionality, defining infrastructure and internal processes. I was also included in some DevOps work (CI/CD, Server Administration etc.) As a team leader I mentored less experienced colleagues. I also had some talks in PHP Meetups in Brno. A few months before I left this position, we started building completely new e-commerce solution based on Sylius. Me and my team had to design whole new extendable application and complete delivery process (using Kubernetes in GCP). I continued working for oXyShop remotely (part-time) during my stay in Canada (10/2016-09/2017).

I worked on multiple high traffic (video) dating sites (mainly in PHP) in a team of 6 people. We used the Microservices pattern. All applications run in Docker containers with high availability needs. Communication among services was ensured by RabbitMQ and REST APIs, container orchestration by Marathon. Whole team emphasized on code security, since we worked with a lot of confidential data, credit card numbers included. Last six months I worked remotely from Brno in EDT timezone.

This company provides its own CMS, so I spent huge amount of time by refactoring legacy code. I was mainly focused at developing new CMS modules, developing Facebook applications and working with various e-commerce projects. I also created multiple projects based on Symfony 2 framework, occasionally helped with Linux server administration, wrote various scripts (data imports and exports) and optimized projects' performance.

Cooperation with multiple companies, especially advertising agencies.

Full stack web developing with XHTML, CSS, PHP and MySQL.
