Hi, I'm ALI YAHYAOUI

Built and ran data pipelines using FastAPI to connect CargoStack with machine learning models for forecasting and pricing. Managed data and supported revenue systems, working directly with cargo clients including Qatar Airways Cargo, Emirates SkyCargo, Etihad Cargo, and Air France-KLM Cargo, and indirectly supporting transport clients such as SNCF, OUIGO, Transavia, and BlaBlaCar.

Designed and ran background cron jobs using Remoulade and RabbitMQ to process data asynchronously, improving reliability and data flow to the data warehouse. Migrated the data warehouse (schema updates + data quality checks) and collected, cleaned, and prepared client data for overbooking, fuel, and demand forecasting.

Worked closely with product, data, and ML teams and monitored pipelines using Grafana and Prometheus. Improved pipeline throughput by offloading long-running jobs to asynchronous workers, keeping API latency stable while processing 100K+ daily records across multiple cargo clients.

Maintain and support production business systems, ensuring stability, performance, and smooth operations. Investigated and resolved 30+ production incidents through Trello-managed tickets, keeping critical business systems stable.

Work directly with clients to collect and analyze requirements, translating needs into reliable solutions. Mentor and support developers, conducting code reviews to improve quality, consistency, and delivery speed.

Manage authentication and access control with Keycloak; strengthen system security and streamline user management.

Owned and delivered business-critical modules across a large enterprise platform, balancing correctness, security, and UX. Led the migration of legacy modules to a microservices architecture with Angular, improving scalability and maintainability, and regularly proposed pragmatic solutions to complex problems across backend services and UI workflows.

Increased performance using caching and deep SQL/PL/SQL optimization, achieving 3-5x faster execution in key flows. Authored architecture/design documentation (diagrams + implementation plans) and facilitated cross-team planning for large initiatives, turning year-long scopes into sprint-sized deliverables.

Delivered highly customizable client features (configurable lookups, shared adjustable statuses across screens, multi-language with client-specific translations) and built/optimized data-heavy UIs over very large tables (millions of rows) with advanced search/sort, lazy loading, and tuned queries. Designed a large hierarchical tree (millions of nodes) with fast search and lazy expand/collapse. Reduced onboarding time from 3 hours to 30 minutes by Dockerizing applications and automating environment setup. Drove research initiatives, introduced new dev tools, and supported high-profile clients (Pearson, Disney, L'Oréal) with diagnostic queries and data fixes, ensuring data integrity and confidentiality.

Built responsive UI for an e-learning platform using React across desktop, tablet, and mobile devices. Developed interactive interfaces and managed state using React hooks and modern patterns. Collaborated with the design team to deliver pixel-perfect components, contributing to a product now used by 1,000+ students.
