PROFILE

Lars Moastuen

Worked on the cognite-sdk-js repository to enhance backend reliability and streamline release processes. Developed an HTTP request retry mechanism using exponential backoff with full jitter, replacing fixed delays to mitigate thundering herd effects and stabilize performance under high load. Automated the NPM package release workflow across multiple packages, ensuring changelogs and dependencies remained synchronized through yarn.lock updates. Leveraged TypeScript and Node.js to implement algorithmic retry logic and CI/CD automation, focusing on network programming and package management. The work improved production resilience and simplified multi-package releases, demonstrating depth in backend development and release management within a complex monorepo environment.
