Turkey

Message

At Parolapara, I architected and implemented microservices and RESTful financial APIs for digital wallet and payment systems. I also developed event-driven messaging across wallet, payment, and notification services, and used transaction protocols and idempotency guards to protect ledger integrity.

At Parolapara, I tuned PostgreSQL and MySQL queries to reduce critical API latency by over 30%, and implemented OAuth2/JWT authentication, rate limiting, and immutable audit trails. Earlier, at Wookweb, I developed contract-first APIs with OpenAPI/Swagger that accelerated frontend and mobile integration.

I’ve also built server infrastructure for Lynrai, an AI media app using Google Gemini API, and designed service infrastructure for DresAura, a virtual fitting room. For Acil Kan, I created an emergency dispatch and blood donation platform with real-time push notifications.
