Description
A high-performance utility designed to help vehicle owners instantly verify ethanol fuel compatibility. Features an AI-validated dataset of over 30 manufacturers and 50+ models, served via an optimized indexed search engine for sub-millisecond query performance.
Which Ethanol is a responsive web tool that allows vehicle owners to check their vehicle's compatibility with varied ethanol fuel blends. The dataset is cross-checked using AI agents and updated via community contributions to ensure maximum safety.
Misfueling is a massive issue for vehicle owners as higher ethanol percentages (like E85) can corrode non-compatible engines. Misfueling information is hard to parse and scattered across lengthy PDFs.
I designed a mobile-first, glassmorphism-based lookup utility. Drivers can select their vehicle brand, model, and manufacturing year to instantly receive detailed compatibility results and recommendations.
Next.js App Router serves as the frontend, communicating directly with a MongoDB database via Mongoose. Search suggestions and query filtering are handled on the server, utilizing indexed compound search properties to return matches in sub-millisecond ranges.
Compiling and cleaning data for hundreds of legacy cars where compatibility guidelines varied heavily by region and manufacturer models.
Implemented compound database index layouts on brand, model, and year fields. I also configured Next.js static page caching, making the main search directories render near-instantaneously from Vercel's CDN nodes.
Delivered over 100,000 lookup queries with zero server lag, helping hundreds of active users avoid engine damage.
