This migration was pivotal for our SaaS platform, addressing B2C, B2B, and internal management needs. The project involved complex multi-language content migration, achieved through integration with Lokalise, and the development of a new UI design system using Isolated Styled Components and Storybook for visualization, complemented by Jest for unit testing.I spearheaded the research and performance testing of various tools and libraries to ensure a smooth transition. I also played a key role in configuring the new workflow with Docker, orchestrated by Kubernetes and managed via Istio.As a web application security specialist, I overhauled existing workflows to enhance security, prevent vulnerabilities, and ensure peak performance. I implemented measures to comply with SOC2 requirements and safeguard data. I integrated communication between multiple microservices using NextAuth on the frontend and a proprietary solution with Nest.js on the backend. My responsibilities included conducting static and dynamic code analysis to detect security issues, training teams on new data handling workflows, and ensuring compliance with GDPR regulations.
