What I'm looking for

I’m looking to join a cutting-edge company and contribute to imaging projects.

At VeracityAI / Wenn ASA, I improved the Size Coefficient Estimation service to 75% average accuracy and reduced its execution time by 20%. I also refined the Face Blur Service, cutting costs by 57%.

I shipped a semantic segmentation model that improved Damage Size Estimation Service accuracy by 10%. I also maintained services and managed AWS deployments with CI/CD pipelines to achieve 99% uptime.

At OREL IT Pvt Ltd, I designed a remote patient monitoring proof of concept that detected critical signs with 90% accuracy, then supported its deployment to a local hospital. I also managed and mentored machine learning engineers and interns.

On my ongoing Autonomous Robot with Stereo Vision project, I integrated YOLO-based object detection into a ROS2 pipeline and designed custom ROS message formats that reduced detection-output bandwidth by 50%. I’m developing its perception and control systems for real-time obstacle avoidance.
