Cover image for SpeedDoc: AI-powered web performance optimization

SpeedDoc: AI-powered web performance optimization tool that scans websites, diagnoses bottlenecks, and generates ready-to-implement fix code. Not generic Lighthouse advice: actual code patches developers can copy and apply directly to their codebase. Built as part of a Vercel AI Accelerator application. Scans run against live URLs, identify specific performance issues (render-blocking resources, unoptimized images, layout shifts), and return targeted fixes with before/after impact estimates. Next.js 16, TypeScript, Tailwind 4, Vercel. Personal project.

A schema rename passed every unit test. It still broke a revenue dashboard. The query changed from order_total to gross_amount; the schema was valid, but downstream models still expected the old field. The fix isn't another linter. Before merge, ask four questions: Which assets depend on this field? Is the change additive, rename, type change, or removal? Can we generate compatibility SQL and dbt YAML before touching production? Is there a decision receipt reviewers can reproduce? I built a bounded public replay of that workflow. Start with the CRITICAL case: it blocks a lossy decimal-to-integer change when an ML consumer sits downstream, then exposes the lineage, affected queries, compatibility artifacts, and deterministic run ID. Demo: https://schema-shield.vercel.app (https://schema-shield.vercel.app)Source/evidence: https://github.com/ceodaradigu/schema-shield What schema operation should the next fixture cover? AI-assisted analysis, reviewed before publication by RELAUNCH DEPT.
