Öne çıkan mühendislik ve yazılım projelerim
I developed an AI-powered personal robot assistant using ESP32-S3 with real-time voice communication. The system uses ASP.NET Core 9 and WebSocket for asynchronous communication, integrates DeepSeek and OpenAI APIs, and uses Edge-TTS for customizable speech. It also includes OLED-based emotional expressions, a web control panel, conversation memory, API/token optimization, analytics dashboards, and Docker deployment.
I contributed to an IoT service health monitoring system using MQTT for real-time device communication, InfluxDB for time-series data storage, and .NET Worker Services for data processing. I also developed service status, CPU/RAM monitoring, SignalR-based real-time updates, and Telegraf integration.
Developed the backend services for a car rental web application using C#, ASP.NET Core Web API, layered architecture, and SOLID principles. The system enables users to register, authenticate, view available vehicles, and rent cars based on their Findeks credit score and selected rental dates. Microsoft SQL Server was used for data storage
