At Nexa, I helped build a multi-tenant B2B SaaS platform for property and facilities management from scratch. I designed backend services and REST APIs with TypeScript, Node.js, Express, and PostgreSQL, including tenant data isolation and role-based access control.
I also architected AWS infrastructure with Terraform across development, testing, and production environments. At Nexa, I built an AI copilot for conversational platform actions and a maintenance diagnosis system using RAG and LLMs.
For maintenance workflows, I developed an AI classification pipeline using OpenAI embeddings and pgvector to route requests through semantic search. I also implemented production WhatsApp integrations with verified webhooks, delivery tracking, and automated notifications.
Earlier, as a Software Engineering Intern at ITGate, I built EduTunisia, a course marketplace, and designed a payment system integrating eDinar, D17, and bank transfers. My projects include a voice conversion model and an end-to-end MLOps pipeline for ticket classification.
