Rick Sanchez

At JV DIAMOND TECHNOLOGY LIMITED, I developed features for a multi-brand online gaming platform, including third-party game provider integrations and player-facing and admin REST APIs. I wrote idempotent Sidekiq jobs so retries never paid out twice.

I also built features for large agent and user trees, using batched queries and eager loading to avoid N+1 queries. For the team, I created Claude Code workflows for Jira ticket kickoff, merge request descriptions, status sync, provider scaffolding, and code review rules.

At 5xRuby Co., Ltd., I was a core developer on the PAKA Time Clock System, building mobile clock-in APIs and workflows for missed punches, resignations, and reviewer assignments. I also integrated the Taiwan company registry API and wrote 32 RSpec test files.

At Beseye, I built back-end logic for AI video analytics and contributed as a core developer to an SOP compliance module. In my WCAG Pulse side project, I built an accessibility scanner that uses Ferrum and axe-core, processes scans with Sidekiq, and supports Stripe subscriptions and reports.
