Hi πŸ‘‹, I'm Ruhal

Machine Learning Engineer | Computer Vision | LLM Systems | MLOps | AI Applications


πŸš€ About Me

I am a Machine Learning Engineer focused on building practical AI systems that move from research ideas to real-world deployment.

My projects are pretty diverse like computer vision, object detection, OCR, facial landmark detection, LLM-based applications, multi-agent systems, synthetic data generation, and production ML infrastructure.

I enjoy building complete AI pipelines: from data collection and annotation, to model training and evaluation, to deployment on cloud, backend systems, and edge/mobile devices.

Currently, I am pursuing an M.Sc. in Artificial Intelligence at Brandenburg University of Technology Cottbus-Senftenberg, Germany and want to contribute to research advancing ML models for which I am working on gaining and advancing relevant skills. I also enjoy reading and testing out new innovations.
