I keep production systems healthy and build for the web: seven years of incident response, automation, internal tooling and production frontends across Azure, GCP and Cloudflare. Open to full-time, part-time and contract work.

Experience

QA & Support Engineer · jpg.store

Sep 2022 – Jun 2026

Remote

  • Production operations for a Cardano NFT marketplace with 168k+ users: healed stuck transactions, recovered crashed services, and ran the blockchain scraper.
  • GCP and Cloudflare incident response: network troubleshooting and on-chain investigation. Worked directly with the CEO, CTO and CPO, trusted with escalation calls.
  • Owned QA across the web platform and the mobile apps: test planning, manual testing and bug triage of every branch before release.
  • Built internal Retool dashboards for transaction healing, listings and process health; contributed design rollouts, bugfixes and features to the Next.js frontend.
  • Led the move from bespoke ticketing to Intercom: help centre, AI workflows and a chatbot deflecting 64.6% of conversations. Wrote 150+ articles read by 60k+ people a year.
  • Started on weekend tickets, earned production-infrastructure access, and stayed to the final team of seven as the company wound down.

AI-Assisted Development

Claude Code (subagents, hooks, MCP servers) · Cursor · ChatGPT · Headless and scheduled agent runs · AI workflow and chatbot design (Intercom)

I run Claude Code as a system rather than a chat window: subagents for multi-step work, hooks that run detectors and tests after every edit, and scheduled headless runs behind my own automation. Where an AI step does real work in a pipeline, I build validation, timeouts and monitoring around it.
