Juha Jantunen is a Senior Developer based in Helsinki with over a decade of professional experience and roots in programming dating back to the Commodore 64 era. He specializes in building integrations, microservices and APIs using Go and PHP, and regularly works with Docker, MariaDB, MongoDB, Redis and RabbitMQ. Juha has delivered backend systems for e-commerce and mobile apps at companies like Verkkokauppa.com, Property Finder and currently SOK, with hands-on AWS and GO development.
