I’m a Senior Front-End Developer and Tech Lead with nearly 10 years of experience building scalable enterprise applications and driving complex architectural migrations. I specialize in architecting robust micro-frontend platforms that support thousands of users and process billions of data points.

At Cognite, I lead front-end development and technical direction for a large-scale micro-frontend ecosystem, authored critical technical design documents, and delivered a first-of-its-kind cross-application POC to secure stakeholder alignment. I use API contract-driven development and mocked endpoints (MSW) to enable parallel development and unblock front-end workflows.

I’ve repeatedly improved delivery speed and reliability: I orchestrated complex deployment matrices across feature-flags, environments, and cluster regions; migrated from Jest to Vitest and established automated smoke/regression pipelines; and scaled an NX monorepo from a single-team project to support 20+ teams. I also led a Webpack to Vite migration in a SystemJS-based micro-frontend architecture and engineered a trunk-based release pipeline that reduced release times from hours to ~1 minute.

I’m equally focused on quality and operational excellence. I champion production observability (telemetry setup, remediating critical CVEs, and high availability), and I build teams’ momentum by unblocking external engineering teams, fixing cross-repo auth setups, and onboarding Design and Documentation teams to independently contribute code.
