Senior Frontend Engineer II · Tech Lead
2023 – 2025- Integrated Webpack Module Federation into the in-house isomorphic micro-frontend framework used by 150+ engineers, removing major blockers to incremental modernisation of legacy stacks.
- Led the migration of 50+ high-traffic web components to React and micro-services in the company’s largest product vertical, sequencing the work to keep experiments running and avoid a big-bang cutover.
- Defined the target architecture for federated frontend services — how they interoperate with existing backend layers — and worked across teams to get buy-in.
- Drove the team’s move to AI-assisted development: built the learning path, ran structured experiments on real workflows, and presented results and trade-offs to leadership.
- Mentored engineers through architecture reviews, onboarding and internal talks; maintained shared libraries used across departments (isomorphic i18n, error reporting, TypeScript helpers).
Senior Frontend Engineer
2021 – 2023- Extended the micro-frontend framework to a second UI library (Vue.js): build, execution and distribution of components, a translation library covering 40+ languages, and integration with the internal A/B testing tool and GraphQL layer.
- Owned the delivery path end to end — publishing assets to CDNs, application health metrics, and Kubernetes/Docker environments.
- Ran micro-frontend services in production: dashboards, SLAs/SLOs, alerting policies, failovers and business continuity.
- Wrote the platform documentation, community guidelines and migration guides, and interviewed frontend candidates across departments and seniority levels.
Frontend Engineer
2018 – 2021- Migrated the most business-critical page of the partner-facing product from a legacy Perl/Mason stack to Vue.js, coordinating the work across QA, backend and frontend.
- Built shared components used by dozens of engineers and delivered features globally through A/B experiments, with responsive and accessible implementations.
