Ertan Karadeniz

I'm currently building a Kafka-based event bus architecture at ingot, designing event schemas, consumer groups, gRPC services, and platform search with ASP.NET Core, MongoDB, Redis, and OpenSearch.

Across 20+ years, I've built payment and transaction platforms for Qlub, Profilo Ödeme Sistemleri, Smartlive Markets, and Turkinvest Brokerage. My work includes restaurant payments, POS and TSM integrations, trading systems, real-time Redis pub/sub applications, payment-provider integrations, and high-traffic REST APIs.

As a freelance backend developer and software architect, I designed customs-clearance and private security operations management systems using Go, C#, Python, databases, integrations, and service-oriented APIs.

I also independently built AirPlay Proof Enterprise, a provable radio-airplay detection platform using Go microservices, Kafka, audio fingerprinting, ONNX inference, signed ledger events, and sharded indexes. In a 24-hour live soak across 22 Turkish radio stations, it processed 261,050 segments with zero false confirmed plays and zero downtime.
