A selection of systems I've built — from live products to internal platforms and experimental R&D.
Projects are not published on GitHub due to security and client confidentiality reasons.
Multiplayer Word Chain Game
Cross-platform word chain game with 70,000+ word dataset, Turkish-English hybrid mode, MMR-based competitive matchmaking, real-time Socket.io matchmaking, Clean Architecture + MVVM Flutter structure, and a comprehensive statistics engine.
Most word games break at scale because they treat words as simple strings. Word Loop treats words as validated entities with difficulty, language constraints, anti-cheat rules, and session integrity.
It's not a game UI — it's a system: dataset pipeline + realtime engine + ranking + stats + operational tooling.
Designed to support long-term seasonal content (leaderboards, events, balancing).
Mystical Fortune, Tarot & Astrology Platform
Kozmira is a comprehensive mystical interpretation platform that combines fortune-telling, tarot, and astrology with modern technology. Features custom content analysis layer for user images, text interpretation engine, themed modules, premium content system, and modern Flutter interface.
Product loops designed to keep users returning through daily content with fixed 24h cycles, premium draw cadence with time-gated access, history & personalization, and rewarded unlocks with ad-to-coin mechanics.
Kozmira is built like a content + systems platform: interpretation engine + delivery + monetization + internal operations — not a single fortune screen.
A centralized operations control center for monitoring and managing services: CPU/RAM/Disk/Network, uptime, and service health — designed for multi-service environments.
Automation platform and bot service foundation with modular command handling, event listeners, and integration hooks.
The public-facing site for EZTN Studio — built for speed, clarity, and a premium visual identity with animation-first UI.
Personal brand, projects, technical profile, and showcase portfolio site. Minimal design with dark/light mode and MDX-based content.
A web control panel built for player statistics, match history, and operational visibility around the Word Loop ecosystem.
A custom admin panel for controlling content modules, prompt templates, premium cycles, and operational toggles for Kozmira.
A shared authentication layer used across products — designed to unify identity, permissions, and token handling in one place.
A file distribution layer built to securely store and deliver user media and app assets over S3-compatible storage.
A unified feedback and analytics intake service for collecting product feedback, lightweight event logs, and operational signals.
Collections are grouped sets of smaller systems — utilities, wrappers, prototypes and archived ideas. They are not "small because unimportant", but because they're focused.
