About

I work on backend and applied AI

Portrait photo of Ahmet Can Yamaç

I'm a Software Engineering graduate with professional backend experience in Laravel/PHP, relational databases and Docker. I've built enterprise audit workflows and integrated RAG (retrieval-augmented generation) for document search and an audit assistant. My focus is backend engineering and AI-powered applications.

KVKK-RAG Detayları

A RAG assistant over 373 official documents using hybrid search and cross-encoder re-ranking. 27 experimental configurations were evaluated against a hand-built gold dataset; MRR rose from 0.380 to 0.657 (+73%). Includes a FastAPI/GraphQL API, document generation and a web interface; runs in GPU-enabled Docker containers.

Perfas Detayları

I built Laravel backend features for a business process and performance analytics platform, focusing on structured data management, scalable architecture and performance-critical functionality.

Internal Audit Management System Detayları

An ERP-based system: audit planning, findings, corrective actions, reporting and role-based access control. RAG was integrated for document search and an audit assistant.
