Work Experience
SORGA Sp. z o.o.
Hybrid (1x office)
Tech Lead for a multi-tenant SaaS platform (PHP/Symfony) serving ~200 clients with a "database per tenant" architecture (~600 MySQL databases). Actively writing code - approximately 70% of my time is hands-on development.
- Led a 7-month migration from PHP 7.2 to 8.3 and MySQL 5.7 to 8.0, utilizing PHPStan level 6 to analyze 500k+ lines of code. Implemented modern programming patterns, increasing performance by ~40%.
- Designed gradual Symfony integration with existing application code, enabling modernization without the need for a complete system rewrite. Implemented Symfony Messenger, EventDispatcher, and Mailer components.
- Implemented a message queue system (Azure Service Bus + Symfony Messenger) processing high volumes of events with automatic retry mechanism for failed messages.
- Participated in infrastructure migration of 200 clients from on-premise to Microsoft Azure, responsible for PHP code implementation - integrations with 6 Azure services, provisioning via Terraform.
- Built developer tools improving team workflow: Makefile for task automation (deployment, tests, migrations), Symfony CLI commands for database and client configuration management, tools for debugging multi-tenant architecture.
- Lead the development team and support the service team in fixing reported bugs through technical consultations. Actively programming - most of my time is spent writing code and conducting code reviews.
