About

I am a Lead Software Engineer with expertise in distributed systems, backend development, and cloud infrastructure. Currently at DataXight, I work on distributed DataLoaders for Single Cell Data training with Ray + PyTorch Lightning, and Terraform/Kubernetes for EKS-based distributed training.

Previously, I led development teams at InspektAI, building computer vision pipelines and 3D annotation systems. I hold an MSc in High Performance Computing from The University of Edinburgh, where I specialized in parallel programming (OpenMP, MPI, CUDA) and GPU optimization.

I'm passionate about turning complex technical challenges into scalable, maintainable solutions—whether it's parallelizing simulations, building serverless pipelines, or architecting cloud infrastructure.

Experience
