Lindustrie-recrute.fr — UIMM job platform
Official job board for the metallurgy industry — candidates, recruiters and CST advisors.
Lindustrie-recrute.fr is the official job board for the metallurgy industry, operated by UIMM (Union of Metallurgy Industries and Trades). The platform connects candidates, recruiters and CST (Territorial Service Centres) advisors across France. It covers the full industrial recruitment lifecycle and integrates with many external ecosystems: France Travail, APEC, MeteoJob, Broadbean, TextKernel, plus an AI-powered CV generation module (Mistral).
My role
Freelance full-stack developer at Ziofix, working on this project since November 2020 (300+ commits). I operate autonomously on functional enhancements, corrective maintenance and infrastructure topics, from Symfony back-end to WordPress front-end.
Key highlights

- Platform in production nationwide
- Decoupled WordPress + Symfony API architecture with async workers
Tech stack
- Public front: WordPress (Bedrock), custom PHP theme, Gulp, Bootstrap
- Business API: Symfony 4.4, Doctrine ORM, REST API (Swagger)
- Search: Elasticsearch 7 (FOSElastica)
- Queues: Symfony Messenger, RabbitMQ / SQS
- Applications module: React (tracking kanban)
- Infra: Docker, Kubernetes (Helm), GitLab CI, Varnish
- Storage: MySQL, S3 (Scaleway)
- Analytics & GDPR: Matomo, TarteAuCitron (CMP)
- Security: Cloudflare Turnstile, OAuth
Third-party integrations
- France Travail — posting and SMOT status synchronisation
- APEC — partner import/export
- MeteoJob — partner import/export
- Broadbean — job distribution
- TextKernel — CV parsing
- Mistral — AI CV generation
- Pelias / ZMaps — geolocation (migration from Google Maps)
- Matomo & TarteAuCitron — analytics and GDPR compliance
- Cloudflare Turnstile — form protection
Front-office (enterprises)
- Candidates — registration, profile, CV library, job alerts, online applications

Quality & infrastructure
- Critical production bug fixes (lock timeout, archived jobs, sync periods)
- Heavy SQL query optimisation (ConsolidateMonthlyOffer, CandidateVoter)
- Elasticsearch 7 migration and maintenance (Painless scripts, indexing)
- Priority Messenger queue configuration and transport restarts
- Memory and cache fixes on critical endpoints
- Ongoing maintenance — labels, popups, salary fields, INSEE postal codes…
Challenges
- Decoupled architecture — WordPress front consuming Symfony API via auto-generated Swagger client
- Integration ecosystem — France Travail, APEC, MeteoJob, Broadbean, TextKernel, AI
- Async processing — exports, synchronisations and ES indexing via Messenger workers
- Multi-stakeholder platform — candidates, recruiters, CST managers and advisors on one ecosystem
