At Wissen Technology, I develop web applications and contribute to Cube Core reporting work. For Central Portfolio Reports, I helped replace a Scala backend service with Node.js and Cube Core, generating SQL dynamically and fetching Snowflake data.
I also built Ag-Grid reports with dynamic filtering and data visualization, migrating existing reports from Power BI. I added Playwright end-to-end tests that reached approximately 70% coverage and used React Query and Redux Toolkit for data fetching and state management.
At BridgeNext, I contributed to React and Next.js features, designed and consumed REST APIs, and developed tests with Jest and Cypress. On Minion, I developed a user access panel with role-based permissions and reusable React components, and provided technical guidance to junior frontend developers.
