About

Backend engineer with 7+ years architecting high-throughput, transaction-heavy distributed systems across fintech, blockchain intelligence, and high-growth startups. I've shipped a real-time prediction market terminal 0→1 as a founding engineer — portfolio tracking, order management, live market data — and run petabyte-scale ingestion in production on GCP and AWS. I deliberately moved from engineering management back to hands-on IC work — owning hard systems end to end is what I do best.

Experience

Founding Engineer

Fireplace
Remote • Feb 2026 — Present • pro.fireplace.gg
  • Shipped the 0→1 product — a real-time prediction market terminal with portfolio tracking, an order management system, and live market analytics — owning end-to-end architecture and delivery.
  • Built the low-latency TypeScript backend powering the web app and a conversational agentic bot — APIs, auth, application logic, and real-time streaming delivery to clients.
  • Built the on-chain indexing pipeline in Rust and ClickHouse, ingesting live blockchain transactions at scale to power position tracking, wallet-level PnL, search, and global leaderboards.
  • Designed a real-time trade detection engine surfacing insider and unusual activity by correlating live on-chain flows against historical baselines.
  • Bootstrapped the engineering stack from scratch — cloud, metrics, search, and CI/CD.

Senior Software Engineer

TRM Labs
Remote • Sep 2024 — Jan 2026
  • Designed and operated petabyte-scale batch and streaming ingestion on GCP — BigQuery, Dataflow, Airflow — processing 10,000+ events/sec across Aptos, ZKSync, and Hyperliquid, unlocking ~$2M in enterprise revenue.
  • Built keystone asset-transfer datasets powering the AML and compliance detection models used by financial institutions and government agencies across the platform.
  • Cut infrastructure spend ~30% (~$100K annually) via storage tiering and containerized compute; architected an agentic multi-source data acquisition platform that halved processing latency.

Engineering Lead

Zluri
Bengaluru • Apr 2024 — Sep 2024
  • Led a 5-engineer data product team shipping user, application, and activity-tracking features on the Shadow IT discovery engine spanning 50+ SaaS sources.

Engineering Manager

Postman
Bengaluru • Jan 2019 — Apr 2024
  • Promoted twice over 5 years (Data Engineer → Technical Lead → Engineering Manager).
  • Led a multi-region data residency and governance initiative across Product, Legal, and Engineering — compliance-sensitive systems work that unblocked enterprise expansion.
  • Built and mentored a team of 7 engineers, implementing agile processes that improved delivery predictability.
  • Architected a multi-tenant data lakehouse and platformized the transformation layer with CI/CD and testing frameworks — boosting downstream developer productivity by 40%.
  • Scaled in-house data integration platform “Fulcrum” to 60+ integrations and 20+ contributors; built near real-time EL, server events, and clickstream pipelines underpinning company-wide analytics and experimentation.

Co-Founder

Eatopedia
Dehradun • Nov 2016 — Dec 2017
  • First founding experience — built web, mobile, and a Facebook Messenger chatbot end-to-end; acquired 5K users and onboarded 50+ restaurants.
