RealVNC
2017-present
Starting with remote access to Raspberry Pi, I have used it in all kinds of situations: connecting via RDP, connecting to VPS machines, and accessing my home PC while away. It is useful because using a RealVNC account lets me work without procedures such as opening ports.
Docker
2024-present
I mainly use it for the backend of PENGUIN, the Kyoto University November Festival website. I also use it when running codex-lb, my Codex load balancer, in a local environment.
OpenAI
2023-present
I have consumed the equivalent of more than $4000 in tokens with ChatGPT and Codex. My current development work mainly uses Codex.
Framer
2026-present
I used it for the first time while building this portfolio.
Because of running cost concerns, this website itself is not hosted on Framer. I reconstructed the code exported from Framer in Next.js.
TypeScript
2024-present
I use it as an extension of JavaScript. I do not write strict type definitions very often, so I cannot say I have mastered it.
React
2024-present
I used it secondarily when using Next.js. Personally, I prefer the way Vue.js is written.
Cloudflare
2023-present
It is the SaaS I love. I manage most of my domains and projects with Cloudflare. I have experience with almost every feature, from basic DNS to Zero Trust.
Supabase
2022-2023
I used Supabase in some personal development projects.
- Cloudflare D1 is easier to use inside the Cloudflare ecosystem.
- Running costs are high.
For those reasons, I do not use it now. As of July 2026, like D1, it still does not implement SQL transactions, so I currently do not see a strong reason to choose it deliberately.
Figma
2024-present
I use it in the draft phase of many projects. For example, when creating shared UI components for a festival website, the team developed based on designs made in Figma.
Next.js
2024-present
- Used to build and maintain a festival website.
- Also used to build a portfolio site.
Python
2020-present
It has been used in many personal projects and was also adopted for the backend of a festival website.
Lark
2023-present
I use it mainly as a mail server across multiple personal projects.
Slack
2024-present
I used Slack to coordinate with the team while developing a festival website.
Notion
2024-2026
I used Notion to coordinate with the team while developing a festival website.
Go
2022-2023
When choosing technology for a personal project, I adopted Go instead of Python because:
- the project required processing speed
- multithreading was easy
- I wanted to try a new language
For those reasons I used Go, and ultimately also built a GUI application with Fyne.
Redis
2023-present
I use Redis in some projects to speed up entire websites and reduce external API calls.
MongoDB
2024-2026
I used MongoDB in some projects to speed up entire websites and reduce the number of external API calls. That project now uses Redis instead.
Resend
2025-present
I use Resend for email delivery in multiple projects.
Nuxt
2022-present
It is the framework I am most familiar with.
I have used it for a high school festival website and many personal projects.
I have used it across Nuxt 2 through Nuxt 5.
I also have experience with related services such as NuxtHub.
Vuetify
2022-present
I use it in many projects together with Nuxt, the framework I am most familiar with.
Other Vue UI frameworks I have used include PrimeVue and Element Plus.
Vue.js
2022-present
I have used it in many projects in combinations such as Nuxt + Vue.js and Vite + Vue.js.
I have learned styles from pre-Vue 2 patterns through the Composition API introduced in Vue 3.
New Relic
2024-present
I use New Relic as a monitoring tool in part of a commissioned development project.
I cannot say I use it to its full potential, but I have experience with its basic features.
JetBrains
2022-present
I mainly use JetBrains IDEs for development, especially WebStorm and PyCharm.
Linux
2016-present
Since using a Raspberry Pi in elementary school, I have touched many Linux distributions.
On the Debian side: Debian, Ubuntu, and Linux Mint.
On the Red Hat side: Fedora and CentOS.
I have also used OpenSUSE, Arch Linux, and others.
GitHub
2018-present
I manage almost every project on GitHub.
In collaborative development projects, I manage branches and commits based on gitflow ideas.
In addition to basic repository management, I use:
- GitHub Actions
- Projects
- Codespaces
- Organizations
I use these as part of my workflow. You can view my GitHub account here.
LLMs
-
I mainly use generative AI for coding.
I usually follow OpenRouter trends to catch up with the latest information and try to touch as many LLMs as possible.
Specifically, examples include:
- Z.ai GLM-4.6, GLM-4.7, GLM-5, GLM-5.1, GLM-5.2
- MiniMax M2.5, M3
- Xiaomi MiMo V2-Pro, V2.5-Pro
- DeepSeek V2.5, V3.1, V3.2, V4 Pro
- OpenAI GPT-4.1, GPT-5, GPT-5.1, GPT-5.2-Codex, GPT-5.3-Codex, GPT-5.4, GPT-5.5
- Anthropic Claude Opus 4.6, Opus 4.7
- StepFun Step 3.5 Flash
- Google Gemini 2.5 Pro, 3 Pro, 3.1 Pro, 3.5 Flash
- Moonshot Kimi K2 Thinking, K2.5, K2.6, K2.7 Code
and many other LLMs as well.
PayPal SDK
2025-present
I use PayPal as a payment processor in some personal projects.
Stripe
2025-present
I use Stripe as a payment processor in part of a commissioned development project. I implemented both one-time payments and subscriptions.
Ahrefs
2024-present
I use Ahrefs in part of a commissioned development project for backlink checks, keyword analysis, and similar work.
Twilio
2022-2024
I used it for SMS delivery and phone number verification in a high school festival website and some personal projects.
Zoho
2024-present
I use it mainly as a mail server across multiple personal projects.
Google Cloud Platform
2024-present
I mainly use it for Google Auth in personal projects. My usage is narrow, and I cannot say I have mastered it.
Oracle Cloud
2020-2024
I use it for VMs, but I cannot say I have mastered it.
DigitalOcean
2022-present
I mainly use VMs (Droplets) within the GitHub Student Developer Pack benefits.
Yandex Metrica
2024-present
I use it instead of Google Analytics in part of a commissioned development project. Metrica has Session Replay, which is useful for analyzing user behavior.
Google Analytics
2022-2025
I used it in some personal projects, starting from the old GA era.
Recently I have not adopted it because I am developing more projects that prioritize user privacy, and Vercel or Cloudflare Analytics is often sufficient.
Vercel
2022-present
I use it for parts of a high school festival website, a university festival website, and some personal projects.
I rarely use Vercel for personal projects because the Hobby plan has strict limits and deploying private GitHub repositories that belong to an organization requires upgrading to the Pro plan. I also considered migrating the university festival website to Cloudflare Workers once, but
- Vercel develops Next.js, the framework used by the project, and if a vulnerability were discovered in Next.js, Vercel would likely be the fastest to apply measures such as WAF rules.
- Given the project size, hosting on Cloudflare Workers would require further optimization, and there was no time available for that work.
For those reasons, I decided not to migrate.
Node.js
2022-present
I use it in most website development.
I rarely run production servers directly on Node.js, but when I do, I use pm2 to keep processes resident and clustered.
MySQL
2023-present
I use it as the database for some projects. In recent years I have increasingly used other systems such as Cloudflare D1 (SQLite) and PostgreSQL, but MySQL is still used in some projects.
Backblaze
2025-present
I use Backblaze B2, an AWS S3-compatible storage service, for the file uploader file.ez1.cc.
