Badilk

In the spare-parts market it is hard to know whether a given part is actually compatible with a given phone. Buyers and repair shops rely on guesswork, and mistakes cost money.

A comprehensive compatibility search platform backed by an automated data discovery engine that keeps the catalogue current without manual entry.

As Co-Founder & CTO I own the full product stack: Flutter apps, .NET 8 APIs, the data discovery engine, Ops dashboard and CI/CD on VPS.

Keeping a live spare-parts catalogue accurate without manual entry — a discovery engine with rate limiting, proxy pool, circuit breaker and incremental discovery so search stays fresh under real traffic.

• .NET 8 / ASP.NET Core backend built on Clean Architecture
• Data discovery engine with 6 components: rate limiter, proxy pool, header randomization, caching, incremental discovery, circuit breaker
• Optimized search through PostgreSQL GIN trigram indexes
• Redis, HybridCache, Play Integrity API, OneSignal, MaxMind GeoLite2, JWT revocation
• Full CI/CD with GitHub Actions on a Vultr VPS behind Nginx + Let's Encrypt
