Fares Kataya

I'm a full-stack software engineer with a strong backend focus and hands-on experience building production-grade systems that go beyond typical web apps — connecting software to real-world hardware, AI models, and complex infrastructure.
At my current role at a robotics startup, I've architected and delivered three end-to-end production systems from scratch as the sole full-stack engineer — owning every decision from system design and protocol selection to cloud deployment and performance optimization. That includes a real-time robot teleoperation platform (WebSocket, MQTT, WebRTC), an AI-powered assistant built on Google's Gemini API, and an educational platform with a custom visual programming IDE and embedded device deployment pipeline.
On the backend I work primarily with Spring Boot and NestJS, building RESTful and GraphQL APIs, microservices architectures, and event-driven systems with RabbitMQ and Apache Kafka. On the frontend I work with React and Next.js. I'm comfortable owning the full infrastructure stack — AWS, GCP, Docker, nginx, and on-premises airgapped deployments.
What I bring to freelance clients specifically: I don't just write features, I think in systems. I ask about your architecture before I write a line of code, I flag tradeoffs, and I deliver things that are maintainable and production-ready — not demos.
If you're building something that involves real-time data, AI integration, complex backend logic, or cloud infrastructure, I'm the engineer you want on it.
