Computer engineering

Final Year Project (PFE) Intern — Distributed Security Platform

• Delivered full-stack features for a B2B SaaS platform serving clients across Europe, using React, Node.js,
Express, and PostgreSQL.
• Improved UI rendering performance by adopting Zustand for local state management and TanStack
Query for server-state caching, decoupling UI state from network state and reducing unnecessary rerenders.
• Built RESTful APIs and WebSocket-based real-time features that enabled live collaboration and instant
data synchronization across geographically distributed clients.
• Integrated on-premise large language models via Ollama to automate content generation workflows,
reducing manual effort for end users.
• Collaborated within a distributed Agile team spanning London and Frankfurt, participating in code
reviews, sprint planning, and Git-based feature workflows.

React, TypeScript, Node.js, Express, PostgreSQL, Kafka, Redis, Azure

• Designed a full-stack carpooling platform handling trip search, booking, notifications, ratings, and profile
management.
• Implemented a defense-in-depth authentication system combining JWT access tokens, refresh token
rotation, OAuth 2.0, and HttpOnly cookies to protect user sessions against XSS and token theft.
• Engineered an event-driven booking pipeline: Apache Kafka processes reservations asynchronously to
decouple booking from confirmation, while Redis distributed locks prevent double-booking under concurrent seat requests.
• Organized backend services into Clean Architecture layers (domain, application, infrastructure), allowing
domain logic to remain framework-agnostic and independently testable.
• Deployed the stack using Docker Compose behind an Nginx reverse proxy on Azure Container Apps,
with Azure Blob Storage handling profile image uploads.
• Reduced API-surface errors by implementing Zod request validation schemas and a centralized errorhandling middleware that returned consistent, structured error responses.
