Bring me a broken or unstable SaaS/web app. I’ll reproduce the issue, trace the failure across frontend, backend, API, database or deployment, and deliver a clear diagnosis plus the highest-value fix that fits the agreed first milestone. Best fit: React/TypeScript, Node.js or Python APIs, PostgreSQL, Docker/deployment and browser automation. Verified proof on my Contra profile includes Loosh Boutique, Revenue Ops Control, GoPilot and Urban Points. If the stack is outside my proven lane, I’ll say so before work starts.
