About Me: Nathan Zhang
C++ Architect | MAUI Expert | DevOps Engineer | AI Agent Developer
I am a seasoned software architect and registered self-employed contractor with over 10 years of experience. I specialize in bridging the gap between high-performance low-level systems and modern, cloud-native application architectures.
🚀 Professional Summary
I build systems that are fast, scalable, and reliable. My expertise spans the entire technology stack:
- Low-Level Mastery: 10+ years of Modern C++ (C++20) and C# experience, focusing on high-performance multi-threading, networking, and low-latency optimizations on both Linux and Windows (x86_64 / ARM).
- Cross-Platform Vision: Expert in .NET MAUI, creating high-performance mobile and desktop applications with complex hardware integrations (like BLE/GATT).
- Cloud-Native & DevOps: Deeply experienced in Kubernetes (K3s/Rancher), GitOps, and automated CI/CD pipelines that reduce delivery times by 50%.
- AI-Driven Innovation: Architecting LLM-powered applications using LangChain, AutoGen, and RAG to transform enterprise documents into intelligent knowledge bases.
I operate as a fully compliant B2B contractor, ready to collaborate with global teams across any time zone.
🛠️ Featured Capabilities (Services)
Based on my recent track record, here are the core areas where I can provide immediate value to your business:
1. High-Performance Embedded & IoT Systems
- What I did: Developed 30 FPS real-time video capture and BLE-based full-duplex streaming (8 MiB packets) on ARM Cortex-A7 and AMB82-MINI platforms.
- Business Value: I can help you build responsive, power-efficient IoT firmware and the surrounding ecosystem for smart home or industrial monitoring.
2. Modern Cross-Platform Mobile Apps (MAUI)
- What I did: Built complex BLE configuration apps for BASF, replacing reflection with Source Generators to eliminate runtime errors and boost performance by 20%.
- Business Value: I can deliver a single codebase for iOS, Android, and Windows that doesn’t sacrifice performance for portability.
3. Industrial-Grade Backend & Edge Computing
- What I did: Architected RK3588-based edge computers handling 32 concurrent 1080p AI video streams and Modbus/RS485 battery management systems.
- Business Value: If you need to process massive amounts of data at the edge or build robust ASP.NET Core backends, I have the blueprint.
4. GitOps & Kubernetes Infrastructure
- What I did: Managed multi-cluster deployments using Fleet and Helm, achieving zero-downtime updates and 100% monitoring coverage via Grafana/Kafka.
- Business Value: I can automate your infrastructure, ensuring your services are resilient, observable, and easy to deploy.
5. Enterprise AI Agent Systems
- What I did: Built a private RAG system for a government enterprise, scaling to 1 million documents with search latency under 10 seconds and 90% accuracy.
- Business Value: I can turn your internal documentation into a private, secure AI assistant tailored to your specific business logic.
🤝 Our Promise
When you partner with me, you are not just hiring a coder; you are engaging a partner committed to engineering excellence:
- Transparency & Compliance: As a registered contractor, I provide clear B2B service contracts and full regulatory compliance for international remote work.
- Architectural Integrity: I don’t just “make it work.” I use modern practices (Source Generation, Memory Recycling, Async/Await) to ensure code is maintainable and performant.
- Global Collaboration: Experienced in asynchronous communication (UTC+1 to UTC+8), ensuring progress never stops, regardless of the time zone.
- Quality First: From XUnit testing to 100% coverage of critical events, I build systems that stay up when it matters most.
