About Austin S.

I am a Software Engineer with a strong technical foundation and a proven track record of designing, building, and scaling B2B SaaS and payment platforms from concept to production. I specialize in backend systems engineering, distributed architectures, and cloud-native development, delivering solutions that are reliable, performant, and built to scale. My core expertise spans payment systems, POS integrations, microservices, and data pipelines, with hands-on experience in Java, Spring Boot, Kafka, Redis, Kubernetes, and modern cloud platforms. I have built high-throughput systems handling millions of devices and hundreds of thousands of requests per second, with a strong focus on system design, performance optimization, and operational stability. I bring deep experience across the full engineering lifecycle — from architecture and API design to CI/CD automation, observability, and cross-functional collaboration with QA, DevOps, and product teams. This allows me to move fast, make sound technical decisions, and deliver with both speed and quality. I am passionate about solving complex engineering challenges at scale — leveraging distributed systems, event-driven design, and emerging technologies to build impactful, production-grade software.
