( The short version )

I like the part of engineering where an idea has to survive real users. At EaseMed that meant hospital and vendor teams messaging in real time. At Edactly it means students watching lessons generated from a single prompt.

Outside client work I research distributed training on consumer GPUs, lead a 200-plus member code club at Atria Institute of Technology, and organise hackathons almost as often as I enter them.

Wins

Fifty-plus hackathons. Seven wins. A different problem every weekend.

World models, blockchain, accessibility, healthcare: the theme changes every time. The habit of shipping something that works by the final demo doesn't.

Research

Papers, a book chapter and work in progress.

Most of my research asks one question: how much training can you squeeze out of the GPUs people already own?

Cross-vendor heterogeneous GPU orchestration for distributed deep learning training

Extends GradMesh toward a full conference paper

One orchestration layer over NVIDIA (CUDA), Intel and Apple Silicon (Metal) GPUs, tackling workload partitioning and synchronisation across mismatched hardware and software stacks.

Around the internet

Build logs, hackathon recaps and the occasional win, as they happen.

Let's talk

Email me

  • Software engineering across full-stack product and applied AI or ML systems. I'm at my best on small teams where I can own a feature from schema to deploy and talk to the people using it.

  • TypeScript with React and Next.js on the front, Node.js and Express with PostgreSQL or MongoDB on the back, Python for ML, and AWS (EC2, S3, Lambda, CloudFront) to ship it. For AI work: RAG, LangChain, embeddings and vector databases like Qdrant.

  • Bengaluru, India. My Edactly work is fully remote, and EaseMed was in person in Bengaluru, so either works.

  • Cross-vendor GPU orchestration: one layer that trains across NVIDIA, Intel and Apple Silicon GPUs together. It extends GradMesh, which I'm presenting at IMPACT-2027 in January.

  • Most of it. There are 65+ public projects on GitHub. Client work stays private, but I'm happy to walk through the architecture on a call.

  • My stand-in until I can say hello myself. The model is "Robot Playground" by Hadrien59 (CC BY 4.0); the jumping, waving and section tours are wired up in code on this site.
