Elmy is a French player in the energy transition.

I participate in the development and maintenance of critical applications related to billing, consumption management, and the customer portal.

Main missions:

• Development and maintenance of Node.js / React apps (front & back)

• Implementation of new features with high business impact

• Management of event streams via Google Pub/Sub (GCP)

• Maintenance and evolution of the Docker / PostgreSQL stack

• Active contribution to technical discussions, module redesign, and code optimization

• Writing automated tests (unit and integration)

Stack: Node.js · TypeScript · React · Docker · PostgreSQL · GCP (Pub/Sub) · Jest / Vitest

Impact: Reduction in time-to-market for new features, and standardization of development practices on the Node.js / React foundation.

Mission focused on the complete testing of a critical Angular application (patient record / nursing home) and its continuous functional evolution.

Main missions:

• Design and implementation of the testing strategy (unit, integration, e2e) for the Angular app

• Writing and industrialization of automated tests (CI pipeline, coverage thresholds, reports)

• Test-driven refactoring: modularization, component simplification, regression fixes

• Development of functional evolutions (UX, data access, complex forms)

• Agile collaboration (Scrum), pair programming, and dissemination of good testing practices

Stack: Angular · TypeScript · Jest (unit/integration) · Cypress (e2e) · Node.js · Git CI/CD

Impact: Significantly strengthened test coverage, reduced regressions in releases, stabilization of critical paths (medical), and acceleration of delivery cycles thanks to a quality-oriented CI.

Technical lead of a team of 5 developers and 1 DevOps, responsible for the complete migration of the pneu.rezulteo.fr website and several internal products.

Key project: transition from a monolithic Polymer / Scala foundation to a modern Node.js / React SSR architecture.

Main missions:

• Management of the overall technical redesign (front + back): design, architecture, migration plan

• Optimized React SSR / Node.js development for SEO and performance

• Implementation of a CI/CD with Jenkins and Dockerized integration

• Technical animation: code reviews, pair programming, skill development for developers

• Collaboration with product and marketing teams to align performance and SEO

Stack: Node.js · React · Polymer (legacy) · Jenkins · Docker · PostgreSQL · i18n · TypeScript

Impact:

• Successful migration of a heavy legacy stack (Polymer + Scala) to a modern, lighter, and more maintainable Node.js / React SSR foundation

• +45% front-end performance, -35% build time, and +25% test coverage

• Improved international SEO by 30%, making the site faster and more visible in European markets
