An engineer pursuing reliability and performance.
Yuhi Abe
SRE & Cloud Engineer
Centered on AWS, I have worked in three roles — cross-product SRE (CCoE), product-dedicated SRE and platform engineering — improving reliability, cost, security and developer productivity. I also write guidelines and coordinate among stakeholders.
My strengths are experience across frontend, backend and cloud infrastructure, and openness to new technologies and tools. I enjoy using automation and performance improvements to raise the efficiency and quality of development and operations. I have also spoken at an external tech event.
From frontend and backend to cloud infrastructure — over six years of hands-on experience, now focused on SRE and cloud infrastructure.

Products I build in my spare time.

"The site you are viewing" — a self-introduction page covering my career and track record. Built on the App Router with separated Server/Client components, a design modeled on an operations runbook with CSS-only scroll animations, and a contact form powered by Resend. Available in Japanese and English, with dark mode.
Private project
Dedicated Minecraft Bedrock and Palworld servers, built and operated with Terraform. They start and stop from Discord slash commands and shut down automatically when idle to keep costs down. Backups and configuration changes are automated through CI/CD.
Private project
A web app that brings take-home business income, household finances and the path to FIRE together in one place. It works out how much can go to living expenses after taxes, social insurance and the impact of incorporating, keeps living costs in check with actual spending, and grows the amount available to invest. It also keeps billing between partners clear.

"See the rhythm" — a web app that looks up a song's BPM and lets you practice with a metronome right away. It features a metronome accurate to ±1 ms using the Web Audio API and beat animations that visualize the tempo.
Private projectPersonal use only
"Make the books I bought searchable" — a personal tool that handles only my own library, within the scope of private use. It automates an e-book app through the Win32 API to capture pages, converts them to text with local OCR and Claude, and reduces misreadings through proofreading and image matching. The result is compiled into Markdown that I can ask questions about, with answers citing their source pages.
