I build verifiable AI for places that can't fail.

The trustworthy parts of frontier AI — systems that must be verifiable, autonomous, and safe in regulated, clinical, and physical environments.

01Profile

I work where the cost of being wrong is unacceptable.

I build the hard, trustworthy parts of frontier AI — systems that must be verifiable, autonomous, and safe in regulated, clinical, and physical environments. Shipped: VISCA, a self-maintaining regulated-AI platform; a clinical-AI product in pilot with Stanford Medicine; zero-knowledge identity systems (ETHIndia Global Winner). American Express Software and AI Engineer and published author on trust in AI agents. Currently also building a personal humanoid robot in public.

HospitalsClinical AI, in pilot inside Stanford Medicine — in-perimeter by design.

BanksEngineering trust at one of the world's largest financial institutions.

RobotsA personal humanoid built from scratch — actuation, perception, control.

OrbitA fault-tolerant runtime designed to reach satellite constellations.

02Initiatives

What I'm building — and already running.

Independent initiatives — architected, built, and shipped hands-on. Real systems, in the real world, on infrastructure I designed from first principles.

VISCA

visca.ai · Bengaluru, India

The regulated AI stack that maintains itself.

Kubernetes (k3s)Helm · Fleet GitOpsAzure ×3LiveKit / WebRTCNestJS · GraphQLTamper-evident audit

Building VISCA — the regulated AI stack that maintains itself: identity, scoped credentials, in-perimeter runtime, tamper-evident audit and the speech & language models, shipped inside the customer's perimeter (nothing leaves the wall).
Architected a multi-agent system on one governed substrate — real-time multimodal voice/video conversational agents, autonomous operator agents that deploy and maintain the platform itself, and post-session evaluation agents — multi-tenant and dynamically dispatched.
Designed and built it solo; runs as a self-maintaining, multi-region (3× Azure) HA Kubernetes platform (~90 services across ~30 namespaces) — humans only approve changes matching their security posture.
Targets the gap where ~88% of enterprise AI-agent pilots die at security review; first deployments in regulated healthcare.

Care Collaborative

Stanford Medicine · Remote

Clinical AI for rehearsing the hardest conversations in medicine.

Real-time avatarsStreaming ASR / TTSCompetency auto-gradingRuns on VISCA

Co-built a clinical AI that lets doctors rehearse difficult patient conversations with lifelike AI patients — real-time voice & video avatars that adapt to the clinician in the moment, then auto-grade empathy and clinical-communication competency.
Took it from zero to a pilot inside Stanford — clearing the institutional security & privacy review that kills most clinical AI — and built and operate it nearly solo on VISCA (my own stack).

03Experience

Engineering at one of the world's largest financial institutions.

Engineering and security work inside regulated financial services.

American Express

Software Engineer II

APAC BISO → Global Servicing Org

Aug 2023 — Present

Bengaluru, India

Worked as a Software Engineer I in the APAC Business Information Security Office (BISO) — security reviews, risk metrics (KRIs), and regulator-facing work; later moved and promoted to Software Engineer II in the Global Servicing Org (Oct 2025).
Found and killed a zero-day in an internal service portal, and reported a separate flaw that could have exposed internal data across multiple systems — before either could be exploited.
Patent inventor (currently in filing); built GenAI proofs-of-concept in the Research group.
Published on the official American Express engineering blog — “Trust Without Disclosure: Why Zero-Knowledge Proofs Could Help Build Trust in AI Agents” (May 2026).

04Moonshots

The long bets, built in the open.

Early, honest, work-in-progress. These are where I push hardest on the physical and the impossible.

Ongoing · WIP

1000 Days Robotics

Personal Humanoid Robot

Building a humanoid robot from scratch — actuation, perception, and embodied control — solo and documented in public. A 1,000-day public build.

OrbitalRuntime

Fault-Tolerant Runtime for Space-Based Datacenters

A fault-tolerant runtime that deploys and self-heals workloads across distributed, unreliable nodes — designed to extend to satellite constellations as the deployment substrate for space-based datacenters.
