Summary

Erdem Doğan is a backend and AI engineer based in İstanbul.

  A recruitment-intelligence platform I am the only engineer on. An LLM agent sits on top of a Python and Playwright acquisition layer that keeps 40,000+ agent records current across six national franchise networks — twice a day, with nobody watching.

• May 2026 — Present· Mobile & Backend Developer· Contract · İstanbul

  Avrupa Çocuk platform

  A platform connecting specialists and parents across a multi-branch rehabilitation clinic chain: a Java 25 and Spring Boot 4 backend with six user roles, a Flutter client, and separate deployments per country so regulatory boundaries stay real.

• Dec 2025 — Jan 2026· Junior Game Developer· Contract · Remote · Rome-based team

  WarCry MMORPG

  Core development team of an MMORPG. Refactored C++ game-loop and server-side systems, and automated item and mob data management in Python so database values stayed consistent with in-game mechanics. The engagement ended when the project was discontinued for budget reasons.

  Takes a request in plain language and decomposes it into a chain of ten specialised coding agents — architect, backend, mobile, QA, security, review, localisation — each running as an isolated process against a target repository.

  Triage

  A pipeline that takes messy customer input and turns it into structured data: an urgency score, a category, a two-line summary. When something is urgent, the webhook and the alert e-mail go out on their own.

• 2025· Engineer

  Chess, from scratch

  Chess with all its rules and no chess library — board model, move generation, check and mate detection, and a minimax search with alpha-beta pruning over a tile-based board. Java first, then ported to JavaScript so it runs in the browser. You can play it on this site.

• 2026· Engineer

  NOA

  A SwiftUI iOS app with LLM-backed assistant modes and live market data, kept behind a Cloudflare Workers proxy so no API key ever reaches the device.
