The problem
Vehicle owners and independent mechanics lack quick, reliable access to technical SAE J1979 OBD-II diagnostic fault codes, freeze-frame sensor telemetry, and repair procedures across global automakers.
What I delivered
- Engineered an automotive diagnostic trouble code (DTC) intelligence directory covering 25 global automakers and 149 vehicle models.
- Integrated freeze-frame telemetry sensor specs, DLC port pinout schematics, and verified DIY repair procedures.
- Optimized search indexing and client-side code lookup for sub-second query latency across tens of thousands of diagnostic codes.
Key decisions
Hierarchical DTC indexing
Organized trouble codes by Powertrain, Chassis, Body, and Network standards for instant lookup and zero search friction.
Fast static delivery with edge caching
Leveraged Next.js and Cloudflare edge caching to deliver instantaneous responses for global automotive technicians.
