2020 - 2022
Senior Fullstack Developer + Cloud Architect
My primary responsibility was to deliver software for the internal bank's stakeholders. Due to the company's strategy, one of the leading points of focus was to switch from software to cloud solutions. I supported the company with that movement in projects I worked on and a couple more that needed support. Responsibilities I took part in contained Python development with a frontend written in React and deploying it to the Google Cloud Platform using Kubernetes. The second project was a data-heavy search engine that was meant to find the best matching client. It had to find the best match based on as few parameters as possible, that were mistake tolerant and were delivered blazingly fast.
