Robin TOURNÉ

Full-stack engineer contributing within an Airbus engineering team on human-machine interface (HMI) software for flight management systems, during a feature-delivery and stabilization phase. Engaged as a consultant through Technology & Strategy (T&S). - Architectural Leadership: Introduced domain-driven design practices to a team previously unfamiliar with them, modeling domain concepts and events, and applying eventual consistency with explicit state machines to prevent aggregate conflicts under high request volumes. - Stabilization & Optimization: Diagnosed and resolved side effects and performance issues across a large existing codebase, improving robustness ahead of delivery milestones. - Targeted Refactoring: Refactored highly-coupled sections under tight deadlines, enabling new feature delivery without regressions while keeping the codebase extensible. - Collaboration: Worked directly with the operations team to translate end-user needs into implementation, building UI flows from the design team's mockups.

Founded and architected a comprehensive e-learning ecosystem, managing the full product lifecycle from system design to production deployment - Platform Architecture: Engineered a suite of applications using SvelteKit/Next.js and PostgreSQL, implementing Domain-Driven Design (DDD) principles for scalability. - Product Development (CodeRonin): Built a gamified learning platform for JavaScript/TypeScript practice featuring automated testing suites and achieving 80%+ test coverage via TDD strategies. - AI Integration: Built an LLM-based system that analyzed each student's results to auto-generate the following month's personalized program, progressively scaling difficulty to sustain engagement and motivation. - Operational Efficiency: Automated student progress reviews and program planning, cutting per-student review time from ~30 to ~10 minutes while keeping a human-in-the-loop for final validation. - Technical Leadership: Designed and delivered a bilingual curriculum (FR/EN) covering advanced topics: Clean Architecture, VPS Administration, Functional Programming, and Testing Strategies. Environment: SvelteKit, Next.js, TypeScript, PostgreSQL, Docker, AI Integration, CI/CD, AWS.

Engineered high-availability solutions for a SaaS simulated sports betting platform, ensuring stability during critical live events. - High-Scale Infrastructure: Upgraded legacy infrastructure to AWS (Elastic Beanstalk, ECS), ensuring 99.9% uptime for 50,000+ concurrent users during live sports matches. - Database Optimization: Optimized complex PostgreSQL queries and architecture for high-concurrency demands, reducing data retrieval latency by 40%. - Architecture & Quality: Led the refactoring of legacy codebases using Hexagonal Architecture and SOLID principles, drastically reducing technical debt and production bugs. - DevOps Automation: Architected full CI/CD pipelines using GitHub Actions, automating testing and deployment cycles to cut manual deployment time by 80%. - Monitoring: Developed a real-time system health dashboard using SvelteKit, providing instant visibility into infrastructure performance for the engineering team. Environment: TypeScript, Node.js, AWS (ECS, RDS, S3), PostgreSQL, Docker, SvelteKit, GitHub Actions.
