Kazusou Tsubota

Senior engineer with 11 years of production experience. I build and maintain SaaS platforms end-to-end: Django
applications serving millions of requests, React dashboards used by thousands daily, and AWS infrastructure
deployed with Terraform. I prefer boring technology that works. Django, Postgres, Redis, React. Deploy on AWS. CI/
CD with GitHub Actions. My day-to-day work includes designing APIs, optimizing slow queries, responding to on-call
alerts, and reviewing pull requests
