Hi, I’m Jake Armstrong. I’m a backend software engineer with a decade of experience designing and operating distributed systems at scale. I specialize in Go, Python, and Node.js, owning end-to-end architecture, delivery, and production operations for mission-critical services. I enjoy leading teams, setting quality standards, and mentoring engineers to build reliable, cloud-native solutions.
I’m comfortable across AWS and Azure, delivering microservices, REST APIs, and data-driven platforms that handle high throughput. I’m passionate about performance, observability, and cross-team API governance to align engineering with business goals while keeping a friendly, collaborative culture.
