Technical Support Engineer · TypeScript & React
Technical support engineer who can read and fix the code, not just escalate it. I trace problems through logs, APIs and databases, explain them clearly to the people affected, and ship the fix when it's mine to ship.
I build and support TypeScript/React apps and e-commerce stores for small businesses, and automate the repetitive parts of support with n8n and the Anthropic API. Every recurring issue becomes a fix, a runbook or an automation so it doesn't come back.
