Summary
👤
Senior🎓
Top SchoolRoy Sprowl is a senior software engineer and embedded systems specialist with nearly three decades of experience designing high-reliability products and leading development from requirements to delivery. At Jetstream Software he architects and implements secure, fault-tolerant distributed systems and has hands-on expertise in C, C++, C#, WPF, and low-footprint embedded development across microcontrollers like ESP32 and LPC4357. His background as an electronic systems engineer includes leading precision motion-control projects for military night-vision hardware, instilling a discipline for producing mission-critical, schedule-driven software. Roy has also built a globe-spanning secure RFID programming production system in C# with Azure components and contributed platform ports and FreeRTOS adapters to Microsoft’s Azure IoT C SDKs, demonstrating strong open-source impact on IoT tooling. Based in Seattle, he combines deep technical craftsmanship with excellent writing and communication skills, and brings an unusual balance of calm under pressure—evidenced by teaching high-performance driving and staying on a spooked horse—to fast-moving engineering projects.
