Top SchoolKodai Hiraishi is a Senior Software Engineer with six years of experience building full-stack applications and cloud-native platforms, currently contributing to Affirm’s engineering efforts. He blends front-end fluency in TypeScript/React with back-end expertise in Python, Java/Kotlin, and Go, and a strong DevOps toolkit including Kubernetes, Terraform, and Jenkins to deliver reliable systems at scale. Kodai has shipped impactful features across data platforms and customer-facing web and mobile products—most notably driving a 3000% traffic surge with AI-powered site tools and cutting fraud-related PagerDuty alerts by 90% through a reCAPTCHA scoring microservice. His work on healthcare communications in low-resource settings (secure SMS for maternal care) and experience with streaming and data stacks (Spark, Glue, Redshift, Airflow) show an unusual mix of product impact and mission-driven engineering.
