Jul 2026 — Aug 2026

• Shipped the mock engine (Node.js, Express, MongoDB): matching algorithm, simulated latency, authentication, a full audit trail, TTL-bounded traffic metrics, and an encrypted credential vault.
• Wrapped LLM generation (Python, FastAPI, hexagonal architecture) in a validity verdict with a bounded repair budget — the engine survives the generator's absence.
• Built the studio around Monaco editors with natural-language mock refinement, behind a server-side security boundary. Governing decision: a mock is a contract, not a file.
• Delivered through the platform's CI/CD — Maven builds published to Nexus, Docker images shipped via GitLab CI and Jenkins onto Kubernetes on Google Cloud.

Munich, Germany (remote)

May 2026 — Dec 2026

• Operate Kubernetes and AKS workloads with monitoring and dashboards in Grafana.
• Build and maintain CI/CD pipelines from commit to deployed environment; provision infrastructure as code.
• Backend development alongside the infrastructure work — on European hours with the Munich team, remotely from Tunisia.

Tunis, Tunisia

Jun 2026 — Jul 2026

• Designed the RAG pipeline — chunking, retrieval, and Mistral AI inference — served from a Python/FastAPI microservice.
• Built the platform as Angular + Spring Boot + FastAPI microservices, secured with Keycloak SSO, OAuth2/OIDC, JWT, and RBAC so answers respect the permissions a user already holds.
• Containerized with Docker behind Traefik and Nginx; released through GitHub Actions CI/CD with GPU-enabled inference.

United States (remote)

May 2026 — Aug 2026

• GTM platform: FastAPI backend with Vite and Next.js frontends — LinkedIn, Apollo, Google OAuth and Calendar integrations, transactional email with open tracking, and AI-generated outreach.
• Mushtarry: AI tender drafting and review, an AI tender-committee simulation, vendor shortlisting with risk and compliance scoring, and local-first RAG search (Ollama running Qwen).
• Enforced the governance rule in the architecture itself: AI generates, a human reviews, a human approves — then action is taken.

Remote

Mar 2026 — Aug 2026

• Developed and integrated mobile features in React Native with native iOS and Android integrations, including AI-powered functionality (under NDA).
• Debugged and optimized for reliable cross-platform behaviour, including defects that appeared on only one of the two platforms.

Hong Kong SAR (remote)

Jul 2025 — Mar 2026

• Built the platform's website builder end to end — one of its major components.
• Delivered backend features in NestJS and frontend features in Vue.js + TypeScript, on event-driven workflows over PostgreSQL, Redis, and RabbitMQ.
• Containerized services with Docker and shipped production releases through GitHub Actions. Converted from intern to contract engineer on the strength of delivery.

France (remote)

Feb 2024 — Oct 2024

• Set up and operated a scalable Kubernetes cluster on Azure AKS, from cluster design through deployment, as one of two people on the DevOps side.
• Built GitLab CI/CD pipelines per microservice and standardized the containerized workflow across environments — cutting manual release effort by around 80%.
• Wrote Python ETL jobs processing 50K+ records for operational reports and analytics.

Remote

Jul 2023 — Sep 2023

• Full stack in Spring Boot, Next.js, and MongoDB.
• Implemented web scraping for article and ranking signals, and a scoring algorithm using NLP and OpenAI API signals across 500+ articles.

Tunis, Tunisia

Jan 2023 — Feb 2023

• Angular frontend for browsing and the candidate flow; Node.js and Express backend on MongoDB.
• Trained and integrated a Python model recommending job titles from a user's skill profile across 1,000+ listings.

Tunis, Tunisia

Jan 2022 — Feb 2022

• Built a website from scratch in PHP, JavaScript, HTML, and CSS.
• Grounding in networking — architecture, core protocols, configuration — that led directly to the later CCNA certifications.
