Which technologies do you work with?

Here’s a practical map of what I reach for most often — not an exhaustive résumé keyword list.

Area	Tools
Languages & frameworks	Ruby on Rails, React, TypeScript, JavaScript; Python for scripts and ETL
Data	PostgreSQL, MySQL, MongoDB; Redis; Apache Solr for search
Async & caching	Sidekiq, Solid Queue, Solid Cache
Frontend state	Redux, Redux-Saga
Testing & CI	RSpec, GitHub Actions, Jenkins
Infra & deploy	Docker, Ansible, Capistrano; Nginx, Puma; DigitalOcean
Observability	New Relic, Monit, logrotate

I pick tools to match the problem: Rails for fast, maintainable backends; React when the UI needs rich client state; Python when pulling and cleaning data from CSVs or databases is faster than doing it in Ruby.

This site and my interactive CV are examples of the React + TypeScript side; most of my day jobs have been Rails-first with a React or legacy JS frontend.
