I worked across four product teams (Claims, B2C, B2B, and Security) on a Belgian insurance platform serving hundreds of thousands of customers and partners, within a frontend group of around twelve engineers. • Migrated login to Angular 14 and integrated Okta for identity and access management, building the front-end auth logic and a tailored sign-in experience. • Modernized several applications, some from AngularJS to Angular 14, with no major production incidents. • Promoted automated testing across a codebase with limited coverage, raising the Claims app to more than 70% unit-test coverage. • Supported the move toward more collaborative Agile practices in a heavily governed, compliance-driven environment.

As a senior frontend developer in a team of around twenty-five, I worked on a shared banking platform powering several private and retail banks in France, Monaco, and Belgium, serving close to a million end-users. • Owned the cross-project frontend layer, refactoring the core Angular logic reused by every bank's application. • Built the end-to-end testing strategy from the ground up: automated around a dozen critical UX flows and populated the Storybook component library, lifting release confidence and catching regressions early. • Supported the lead frontend engineers on the core-module migration to Angular 15. • Contributed to a private-bank rollout in Monaco, in a security-first setting with very low tolerance for production defects.

I worked as an Angular developer in a three-person frontend team (within a ~12-person Scrum team) on a public platform for environmental policy in Wallonia, Belgium, surfacing protected-species and zoning data through interactive maps and informative lists. • Built feature flows with a focus on data accessibility. • Worked within a shared back-end / front-end monorepo.

I led the frontend team on the new public platform for one of Belgium's largest health funds, serving millions of members, before handing over to the client's in-house team. • Grew the frontend team from two to five engineers, owning architecture, code review, estimation, and mentoring. • Worked within a self-organizing Scrum team that owned its delivery and presented to stakeholders at each sprint review. • Digitized multiple member journeys previously handled physically: full membership signup, appointments, work-incapacity and hospitalization declarations. • Delivered the site in Angular with server-side rendering (Angular Universal) for SEO, with content managed in WordPress so the client could own its copy. • Hardened the platform with Content Security Policy and front-end security measures, built with accessibility as a core requirement, plus analytics and conversion tracking through Google Tag Manager.
