I'm a passionate Senior Software Engineer focused on building scalable web, mobile, IoT, and cloud-based applications. I enjoy solving real-world problems through clean architecture, performance-focused development, and user-centric product engineering.
Currently, I work with technologies such as React Native, React.js, Next.js, Node.js, NestJS, Express.js, MongoDB, PostgreSQL, AWS, Docker, Kafka, Spark, Elasticsearch, MQTT, and WebSocket.
