Employment History

Brite Payments, Stockholm

I'm currently engaged with Brite Payments, working as a consultant on the Python backend collaborating closely with the engineering team. Our main focus is integrating smoothly with external banks and payment providers. Additionally, we're in the process of transitioning from the older Python 2 code to FastAPI microservices in Python 3. All of this is happening within the GCP cloud infrastructure, where we're utilizing services like Datastore, App Engine, and Cloud Run.

Nogaam Book Publishing, Freelance Project

For this consultancy project, I undertook several key initiatives. Firstly, I updated the Django framework along with its dependencies to the latest available versions. Additionally, I introduced "Renovate" to ensure that dependencies are consistently maintained up-to-date.

Furthermore, I transitioned the service into a containerized environment using Docker. This migration facilitated the shift from a single-instance service to a Google Cloud Run service. This transformation not only enhanced scalability and availability but also resulted in a reduction of the GCP infrastructure costs.
