I'm Scott, a Maker.

Scott Hatfield

Staff Software Engineer

Systems Architecture Mobile Cloud IoT Developer Experience AI

I design and build platforms, products, and developer-facing systems that other engineers rely on to ship reliable products. My work spans API design, distributed cloud services, mobile applications, and internal tooling, with a strong emphasis on developer experience, correctness, and long-term maintainability.

In practice, this means working fluidly across the stack, from front-end product development to shared infrastructure and tooling, and turning complex, ambiguous problem spaces into clear abstractions, well-considered tradeoffs, and scalable systems that are both powerful to build and intuitive to use.

🧭 What I Do

  • Systems Architecture — Designing cohesive platforms that integrate cloud APIs, web/mobile front ends, analytics, and connected devices.
  • Full Product Ownership — From concept and UX prototyping to architecture, implementation, observability, and iteration.
  • IoT & Connected Systems — Building BLE communication stacks, hardware integrations, and real-time device interactions.
  • Cloud Engineering — Azure Functions, Cosmos DB, Firebase, serverless architectures, distributed systems.
  • AI-Augmented Workflows — LLM-based analysis tools, structured reasoning pipelines, and domain-specific AI integrations.
  • Developer Experience — CLI tools, automation systems, testing strategy, CI/CD pipelines.

🏅 Award-Winning Systems

  • IoT Breakthrough Award (2026): Recognized for technical leadership and architecture of the Sub-Zero Recipe Experience, a platform integrating cloud services, internal content workflows, connected appliances, and mobile experiences.
  • Microsoft Azure AI Developer Hackathon Winner (2025): Built Copper, an AI-assisted PCB debugging tool powered by Azure Functions, Cosmos DB, and LLM reasoning pipelines.

🧩 Engineering Philosophy

I believe great engineers think in terms of:

  • architecture, systems, and flows
  • constraints and tradeoffs
  • shared understanding
  • long-term maintainability

My work emphasizes clarity, simplification, observability, and creating systems that can evolve as products grow.
