Stack & Sequence supports product development from early concept through prototype, integration, and production readiness. For a founder or product team, that can mean translating an idea into a technical roadmap, identifying the riskiest assumptions, and building the first credible prototype. For an engineering team, it can mean focused support on embedded firmware, electronics bring-up, sensors, low-power design, DSP, embedded Linux, or system-level debugging. The work is intentionally full-product minded. A connected hardware product is rarely just firmware, a PCB, an enclosure, or an app in isolation; reliability comes from how those pieces behave together. I focus on the electrical and embedded layers directly, and I can coordinate with trusted mechanical/chassis and manufacturing partners when the product needs a broader team. The goal is to help teams move from uncertainty to a working product direction: clear technical decisions, better prototypes, fewer hidden integration risks, and systems that are designed for real-world use rather than just a successful demo.
