@matsudahiroshi
Senior software engineer building scalable full-stack, cloud-native and AI-driven security systems.
BrazilWhat I'm looking for
I’m a Senior Software Engineer with 11+ years designing, developing, and operating scalable fullstack applications, specializing in Python, React, and distributed systems. I’ve led AI-driven enterprise search and security-focused microservices for 100K+ users, including production-grade RAG pipelines and AI agents built with HuggingFace Transformers and OpenAI APIs.
I’m at my best in cloud-native environments where I can improve performance, reliability, and security—cutting API latency by 35–50% and reducing frontend load time by 40%. I also drive secure CI/CD and observability using Kubernetes, Docker, Terraform, Prometheus, and Grafana, and I mentor engineers to raise engineering standards through clear onboarding and reusable sample projects.
