Backend engineer focused on AI product systems.
Mohamed Attig
Founder of Cortex Kernel. Creator of Craftsignal.
I build reliable AI applications by combining high-concurrency Node.js orchestration with Python agent workflows and clean architecture.
- Experience
- 6 years
- AI interactions
- 50k+ daily
Signature systems
Quiet execution, measurable outcomes.
01
AI Guest Service System
Led the core system architecture for INTO AI guest services, including realtime voice handling and stateful agent orchestration.
- Engineered a low-latency Node.js WebSocket gateway bridging concurrent voice streams to Python AI agents.
- Architected LangGraph reasoning flows with strict separation between agent logic and IO layers.
- Optimized Azure ingestion pipelines for unstructured document processing and RAG retrieval readiness.
02
Craftsignal.io
Built and shipped Craftsignal as a product artifact that reflects my founder-operator approach to AI-first software.
- Product direction, architecture, and execution handled end to end.
- Emphasis on robust abstractions, pragmatic delivery, and maintainable systems.
03
Orchestration Pattern
Specialized in pairing Node.js orchestration with Python intelligence layers to keep complex AI workflows stable under load.
- Designed event-driven microservices supporting 50k+ daily AI interactions.
- Implemented Redis pooling and caching strategies to absorb inference usage spikes.
- Built unified internal APIs aggregating service metrics for product visibility.

Featured build
Craftsignal.io
Craftsignal is a product expression of how I build: lean scope, durable architecture, and fast iteration without sacrificing system integrity.
Professional arc
Built for production pressure.
Realtime voice and agent systems
- Built a high-concurrency WebSocket gateway in Node.js for realtime voice streams.
