At Mind Hands, I design full-stack applications with Angular, NestJS, TypeScript, and MongoDB. I also integrate AI agents with Mastra AI and LLMs for data analysis and decision-making.

For BONIAL, I migrated more than 15 front-end modules from JavaScript to TypeScript 5, reducing production bugs by approximately 30%. I also refactored React interfaces and implemented BPMN workflows for data-driven marketing campaigns.

At YANYI, I developed AI pipelines for semantic search and RAG workflows, and built agents to automate tender analysis, data extraction, classification, and summaries. I optimized PostgreSQL and MongoDB databases, improving document search relevance by approximately 40%.

At AlMergab, I developed SaaS platforms and a vehicle fleet management and booking application using React, Angular, and Node.js/Express. I implemented over 40 secure REST APIs and contributed full-stack features to MindPlatform.
