Laurent M.

— Conducted comprehensive security hardening: Argon2id, injection vector elimination, XSS patching, authN/authZ improvements, Trivy and Semgrep integration in CI.

— Built an automated RabbitMQ + AI pipeline for production error triage — structured incident tickets with urgency scoring, improving incident response time.

— Designed a Strategy-pattern content moderation system: extensible, testable, supporting word-list and AI-based validation with zero-downtime rollout strategy.

— Led full PHP 8.2 → 8.5 platform migration: Doctrine ORM 3.6 / DBAL 4.4, CI/CD pipelines, Docker images, and deployment scripts.

— Resolved critical reliability issues: N+1 queries, Swoole worker timeouts, RabbitMQ consumer crash loops — restoring production stability.

— Sole backend developer on the User Experience team: owned API design, architecture decisions, and end-to-end delivery for the commerce and storefront platform serving millions of users worldwide.

— Designed and built commerce APIs covering product discovery, pricing, subscription lifecycle, entitlements, and checkout flows — directly comparable to Autodesk's commerce infrastructure.

— Designed and shipped the Automated Upsells engine, driving increased conversion rates across the pledge store through intelligent product recommendations.

— Migrated legacy Node.js services to a microservices architecture; progressive REST → GraphQL migration enabling more flexible integrations.

— Overhauled the transactional email pipeline (purchase, subscription, account), improving deliverability and engagement at scale.

— Designed and maintained a role-based and attribute-based access control system (RBAC/ABAC): feature and admin-level permissions by role, plus a badge system granting users access to specific SKUs and exclusive storefronts (subscription tier, concierge program).

— Designed and implemented an Elasticsearch search engine with custom indexing for property / contractor matching; React frontend.

—Salesforce integration to feed customer service databases from platform data flows.

— Set up GitLab CI/CD pipelines and Docker environments; applied Hexagonal Architecture and SOLID principles across the codebase.
