In my experience as Software Developer, I gained wide experience in design and implementation of software solutions of various complexity and scale. I develop event-sourced business applications and Docker-Based cloud microservices. Additionally I take care of quality assurance with continuous integration.

• PHP 7/8 (Laminas, prooph, Event Engine, Symfony, ReactPHP)
• Typescript
• React.js
• Node.js
• Java
• C++
• PostgreSQL / MongoDB / ArangoDB / MariaDB / MySQL
• Webservices (REST, SOAP, XML-RPC, JSON-RPC)
• JSON / XML

A Software Developer is only as good as his tools, maybe. Well, I use the following tools to get things done.

• Profiling / Debugging (Xdebug, Blackfire)
• Build / Deployment
• Quality Assurance (PHPUnit, PHP Codesniffer, PHPStan, Psalm)
• Continuous Integration (GitLab-CI, Jenkins, Travis-CI)
• Version Control System (GIT)
• Agile Software Development with SCRUM (Atlassian Products)
• PhpStorm

There are many conceptual things to learn and it will never end.

• Domain-Driven-Design (DDD)
• Command Query Responsibility Segregation (CQRS)
• Event Sourcing (ES)
• Event Storming
• Object-oriented analysis and design (OOAD)
• Object-oriented programming (OOP)
• Database Design
• Test-Driven-Development (TDD)

I have experience in setting up and configuration of Docker-Based cloud microservices.

• Amazon AWS
• Google Cloud
• Docker
• Kubernetes
• Helm
• Terraform
• nginx
• PHP-FPM
• Linux / Unix
