About Me

Contracted SE → Cloud Engineer — Recruited directly, went independent

2020–2021
Vocational School

6-month intensive program → recruited directly by company president

2021–2022
Contracted SE

On-site at private high school. Developed IBM Watson × Slack helpdesk bot. DX case published in local business journal.

2022 –
Freelance

AWS projects, Cloudflare edge platforms, IoT cloud recording, and more — operating independently across multiple engagements.

IAM least privilege · Zero Trust · DMARC — built in by default
Terraform + GitHub Actions OIDC — zero manual changes
MCP × AI agents — routine operations automated
Full remote — async-friendly · EN / JP · freelance / contract OK

What I Deliver

Services

Design · Build · Documentation — all in one engagement across 6 specialist domains.

Edge-Native Web Platform

Most Requested

Fast, low-cost websites starting at a few dollars/month — designed and built end-to-end.

Architecture selection & comparison (Edge vs AWS)
Cloudflare Pages or AWS S3 + CloudFront setup
Contact form & auto-reply email integration
Infrastructure-as-Code (Terraform) & automated deployment (CI/CD)
Domain, SSL certificate & email authentication (DMARC) setup
Architecture diagram, operations manual & handover docs
Inquire / Request

Email Auth & DMARC Compliance

Required in 2026

Fix deliverability before emails stop reaching Gmail / Yahoo. Proper SPF, DKIM, DMARC setup.

AWS SES sandbox removal application support (English template provided)
DKIM setup (email sender authenticity — cryptographic signature)
SPF record optimization (authorized sender registration)
Staged DMARC rollout (monitor only → quarantine → reject)
Bounce & complaint alert notification flow
Email deliverability check procedures & operations docs
Inquire / Request

IaC & CI/CD Pipeline

Eliminate manual console changes. Manage all infrastructure as code with Terraform + GitHub Actions.

Existing infrastructure codification (terraform import)
Reusable module design
Dev/Prd environment separation & state file management
Keyless AWS deployment using OIDC (no long-lived credentials)
Automated pipeline: code push → production deploy
README, operations manual & incident response cheatsheet
Inquire / Request

AI Agents & Ops Automation

Trending 2026

Delegate routine AWS / Cloudflare tasks to AI. Structurally reduce repetitive manual work.

AI Gateway setup (caching, logging, cost limits)
Multi-LLM integration management (OpenAI / Anthropic / Gemini)
MCP server implementation (AI-executable AWS / Cloudflare operations)
Slack & GitHub Actions event-triggered automation flow design
Prompt management & versioning
AI cost visualization & handover documentation
Inquire / Request

Observability & Monitoring

Auto-detect & auto-stop on anomalies and cost overruns. No more "discovered incidents too late".

CloudWatch alarm design & implementation (Terraform-managed)
Sentry error collection integration (frontend & API)
AWS Budgets × Lambda auto-stop flow for cost breaches
Log structuring & fast-search query library
Incident first-response & escalation runbook
Slack / email notification wiring & monitoring design doc
Inquire / Request

Architecture Review & Advisory

"Is this setup really OK?" — diagnosed from both AWS best practices and real-world experience.

Current system architecture interview & document review
Assessment against AWS best practices (5 pillars)
IAM, network security & access control audit
Terraform code review & improvement identification
Cost modeling & serverless vs edge migration comparison
Prioritized improvement report (High / Medium / Low)
Inquire / Request
