What I'm looking for

I'm looking to build scalable, maintainable backend systems, APIs, real-time services, and AI-integrated products while growing my cloud and production engineering experience.

At Greenstate AG, I build and maintain backend services for a smart plant-growing IoT device, covering device management, user sessions, and real-time interactions. I became familiar with the full codebase and business logic from the first day of the project.

I designed CRM real-time communication between customers and support agents, built a DialogflowCX chatbot that supports automated and human conversations in one channel, and owned an Instagram-like Community module from database architecture through API design and business logic.

I’ve also maintained an investor platform with payment systems and investor-owner communication, improving code quality and reliability. By fixing memory leaks and eliminating redundant operations, I reduced processing time from 20 minutes to 5 minutes.

I work with NestJS, Node.js, PostgreSQL, Docker, AWS, WebSocket, and RabbitMQ, and I deploy and debug backend services in production environments.
