ATALAY KARAHAN • Peerlist

I developed backend APIs for Mapastro, an astrology application available on the App Store. My role involved creating robust and scalable systems for real-time chat, Firebase messaging, and implementing Socket.io for live communication features. The project focuses on providing users with an interactive and seamless astrological experience.

MapAstro - Astroloji & Burçlar

A backend for a gamer-focused chat application where only users with over 500 hours on Steam can join. Built with MongoDB, it integrates OpenID for Steam-based authentication, real-time messaging with SocketIO, and file handling with Amazon S3. This project follows Uncle Bob's Clean Architecture principles to ensure a robust, maintainable structure

Settle-Backend

See every Claude Code session on one live screen: which one is working, which needs you, what its agents are doing and what it costs. Each chat runs in its own window and keeps going in the background. Free and open source.I run several Claude Code sessions at once, often with subagents, and I kept losing track of which one was working, which one was waiting for me and which one wanted approval. So I built a native Mac app around them.Every session sits on a live orbit map, coloured by state, with its subagents, tool calls, the files they touch, web research and spend updating as they happen. Each chat has its own window, but the session lives in the background, so you can close the window or quit the app and Claude keeps working. Dev servers and test watchers fly around as cars.There's a social side too: add friends by name#tag, message them, earn XP for the time you actively work and climb from Academy Student to Kage on a weekly leaderboard.Your Claude data never leaves your Mac; the README lists exactly what the small server behind friends and levels receives. It's free, open source (MIT), macOS 13+, Apple Silicon and Intel.
