What I'm looking for

I seek roles building and deploying production ML systems (especially computer vision) in collaborative teams, with opportunities to lead projects and scale impact.

I am a Machine Learning Engineer with four years of experience architecting and deploying AI solutions that improve decision-making, automate workflows, and deliver high-accuracy computer vision systems. I have led large cross-functional teams and built real-time models (CNN, LSTM, YOLO) achieving production-grade results.

My work spans computer vision, NLP (speech, gesture, OCR), MLOps and business process automation, with hands-on experience in model deployment, cloud infrastructure and end-to-end data pipelines. I focus on delivering reliable, scalable systems that drive operational impact and improve user outcomes.
