Senior Lead Developer

Design and development of a business SaaS application enabling companies to monitor their electricity consumption in real time via Linky smart meters. Complex interfacing with the ENEDIS API (C1/C2 flows), processing large volumes of telemetry data and rendering it as business dashboards.

• Asynchronous architecture: Cloud Tasks for deferred processing of high-volume ENEDIS API calls.
• Automation: Batch & scheduling via Cloud Scheduler for nightly collections and data reconciliation.
• Security: Secure OAuth2 / JWT flows, fine-grained permissions per client account.
• Quality: PHPUnit test coverage, systematic code reviews, Cloud Build CI/CD pipeline.
• Management: Supervised an external developer on ENEDIS-specific integration components.

External CTO engagement for the technical direction of a web app for individuals moving house. Supervised an outsourced team, guaranteed code quality and alignment with La Poste's architectural standards. High security stakes tied to the "Mon Compte La Poste" SSO integration.

• Microservices architecture: Oversaw functional decomposition and interface contracts between services.
• La Poste SSO: Integrated OAuth2 "Mon Compte La Poste" — federated multi-scope authentication flow.
• Quality & Governance: Code reviews, standards definition, blocking critical technical debt.

Complete overhaul of the hosting infrastructure: migrated an aging stack on dedicated OVH servers (manual maintenance, outage risk) to a fully code-driven managed GCP Cloud architecture. Goal: zero server maintenance, automatic scalability, enhanced security.

• Infrastructure as Code: Entire infrastructure defined and versioned via Terraform (GAE, GCE, CloudSQL, IAP).
• Database migration: Transferred MySQL databases to CloudSQL with data validation and zero-downtime cutover.
• Security: Secured access to internal resources via IAP (Identity-Aware Proxy), removed ad-hoc VPNs.
• CI/CD: Automated deployments via Cloud Build — end of manual FTP deployment.

Designed a custom architecture pairing WordPress's SEO power (choisir.com, high organic traffic) with complex B2B lead management business logic under Laravel. Challenge: making two fundamentally different systems work together without sacrificing editorial performance or application robustness.

• Secure Laravel API: JWT/OAuth2 endpoints exposing business entities (leads, offers, contracts) to WordPress.
• Composer plugin: Built a native WordPress plugin consuming the Laravel API for seamless integration.
• Third-party feeds: Integrated the ENEDIS API to retrieve PDL (delivery point) data from customer-facing forms.
• DDD: Modeled the business domain (aggregates, value objects) to isolate lead logic from the CMS infrastructure.

Complete transfer of a Drupal ecosystem to a flexible WordPress architecture, for an editorial site with a long content history and high SEO value. Key challenge: migrating several years of structured content (articles, taxonomies, media) with no data loss or Google indexing regression.

• Extraction & Mapping: Custom export scripts for Drupal Nodes and Taxonomies, mapped to WordPress Custom Post Types and taxonomies.
• Automation: Bulk import pipeline via SQL scripts — guaranteed data integrity, zero manual entry.
• Critical SEO: Comprehensive 301 redirect plan — 100% preserved Google indexing, no ranking loss.
• Validation: Multi-phase migration testing with cross-checking of content before going live.
