Senior🎓
Top SchoolSatoshi Tanaka is a Senior Python backend and cloud engineer with a decade of hands-on experience building reliable production systems across media, manufacturing, biometric authentication, marketing ops, inventory, and M&A workflows. He specializes in large-scale data processing, API integrations, and cloud migrations (AWS → GCP), with a pragmatic focus on idempotency, rate limits, retries, and long-term maintainability. Notable accomplishments include validating uniqueness across 1.92 billion hashes within a 12-hour window, designing LSH-based duplicate detection and rate-limited media backends, and triaging ~500 Amazon Inspector findings for security hardening. He has built serverless biometric REST APIs with national ID integrations and ML-ready GCP data pipelines, and contributes to embedded/IoT open-source projects adding microcontroller support and device drivers. Based in Hyogo, Japan, Satoshi excels at clarifying ambiguous requirements, surfacing implementation risks early, and shipping production-grade systems with clear technical writing.
