What I'm looking for

I want an engineering role where I can lead backend and full‑stack work, leverage DevOps/containers and LLM tooling, and build reliable, testable production systems.

I am a pragmatic full‑stack software developer with broad backend and mobile experience, delivering production systems across startups and established teams.

I have led domain exploration and system rewrites, designed and implemented backends, migrated legacy data, and built delivery and educational platforms used by customers in the UK and Poland.

My technical strengths include Dart/Flutter, PHP (Symfony/Zend/Laminas), TypeScript, Go, databases (PostgreSQL, MySQL, MongoDB), message queues, and cloud/DevOps practices — I am a Certified Kubernetes Administrator and fluent with containers, servers, networking, and databases.

I adopt LLM coding assistants to boost productivity while maintaining high code quality and test coverage; I seek roles where I can contribute technical leadership, reliable engineering, and pragmatic product-minded development.
