Staff+ Engineering, at scale

I build and scale business-critical distributed systems across domains, teams, and organizations. At Intuit, I work at the intersection of architecture, product strategy, and engineering execution— turning ambiguous problems into resilient systems that scale with the business.

My work spans commerce, payments, inventory, platform infrastructure, and high-throughput processing, with systems handling 1M+ monthly orders, 200M+ tasks, and millions of daily transactions.

Selected Impact

  1. 12×

    Sales Order scale — Intuit

    Architected and scaled the Sales Order domain across 13+ subsystems, growing monthly order volume from 84K to 1M+ while maintaining zero P0/P1 incidents.

  2. 200M+

    Distributed platform scale — Intuit

    Designed a generic task scheduler for reconciliations, backfills, and purges, processing 200M+ tasks and improving developer throughput by 4×.

  3. $20K+

    Monthly cloud infrastructure savings — Intuit

    Led deep performance investigations that reduced memory consumption by 40%, improved event-processing efficiency by 70%, and reduced AWS DynamoDB and RDS costs by $20K+ per month.

  4. 2M/day

    Payment transaction scale — Paytm

    Re-engineered payment processing into a highly distributed batch architecture capable of handling 2M transactions daily.

How I Work

I turn ambiguous product problems into resilient architectures, align teams around technical direction, and build platforms that improve reliability, cost, and developer leverage.

Why Me

Staff+ impact, not just seniority.

Architecture across domains Payments, commerce, inventory, platform infrastructure, and high-throughput processing.
Scale with measurable outcomes 1M+ monthly orders, 200M+ async tasks, 2M+ daily payments, plus 12× growth and 4× developer throughput.
Cross-org technical leadership Drive architecture beyond one team and align multiple engineering organizations through ambiguity.
Depth + leverage From distributed-system failure modes and performance to reusable platforms that multiply engineering capacity.
Selected Systems

Three systems that show how I operate.

Sales Order Platform

1M+ monthly · 13+ subsystems · 15K+ customers

Architected a resilient order domain that grew from 84K to 1M+ monthly orders while supporting enterprise tiers and zero P0/P1 incidents.

Distributed Task Platform

200M+ tasks · 4× developer throughput

Built a generic scheduling capability for reconciliations, backfills, and purges, turning repeated operational work into reusable platform infrastructure.

Payment Processing Platform

2M+ daily transactions · 20% higher success rate

Designed distributed payment-processing and reconciliation systems, improving successful transactions by 20% while scaling to 2M+ transactions daily.

Engineering Depth

Let's build something difficult.

I’m interested in Staff+, Senior Staff, and Principal Engineering roles where the challenge goes beyond a single service or team—shaping architecture across systems, domains, and organizations. I’m particularly drawn to large-scale distributed systems, platform and commerce infrastructure, and technically complex products where strong engineering decisions can unlock meaningful business impact.
