Where I have shipped, scaled, and taken a lot of cost out of running systems.

Chainrisk Labs

  1. Lead Engineer

    Aug 2025Present

    • Lead a team of 5 engineers across the risk engine, simulation pipeline and cloud platform — owning architecture decisions, review and delivery.
    • Built Chainrisk's Proof of Reserves over ~$1.5B in assets — attestations computed inside AWS Nitro Enclaves for hardware-isolated, verifiable execution, and proven with zero-knowledge circuits written in Circom.
    • Extended the same proof system to real-world assets (RWA), bringing off-chain holdings under the same verifiable guarantees.
    • Rebuilt the Monte Carlo risk engine in Rust with CUDA-accelerated kernels, replacing interpreted per-scenario execution with batched GPU compute: 60× lower cloud spend and 40× faster end-to-end runtime.
    • Parallelised Solidity test-case execution across cores in Rust, taking Monte Carlo runs 16× faster by saturating available compute instead of running scenarios serially.
    • Built AI agents that automate the risk-analysis workflow, turning a manual analyst process into a reproducible pipeline.
  2. Lead Cloud and Infrastructure Engineer

    Jan 2024Aug 2025

    • Designed and built Chainrisk's entire cloud architecture from the ground up, then owned the whole infrastructure footprint end to end.
    • Architected the automated risk-analysis pipeline that sustains 6M+ large-scale simulations per day.
    • Standardised every environment as code — workloads containerised with Docker, orchestrated on Kubernetes, provisioned with Terraform and Ansible on AWS.
    • Owned reliability, capacity and cost across the platform, keeping environments consistent from local development through to production.
  3. Software Engineer

    Dec 2022Feb 2023

    • Built the bounty and audit platform on GCP in TypeScript and Go.

  1. Software Developer Engineer

    Oct 2023Jan 2024

    • Brought the company's software stack in-house on GCP and Firebase, taking monthly running cost from ₹30,000 to under ₹1,000 — a 30× reduction.
    • Owned backend and infrastructure in TypeScript and Go, replacing paid third-party services with self-hosted equivalents.
