30–35s → 3–5s
cold query in production
Rebuilt the query path behind a financial analytics API
A financial detail report query over an indexed 519M-row table took 30–35 seconds to load. In production it now returns in about 3–5 seconds from a cold cache and 0.8–1.6 seconds once warm.

30+ engineers
build on it · 3 apps live
Co-established the shared platform that other engineering teams ship on
Not one service. I worked on the shell that other teams plug their apps into and the packages they import from it, and led 60+ deployments across three months. 30+ engineers across teams build on it.

4–5 → 2–3 months
average B2B contract cycle time, 40–50% shorter
Built a GenAI assistant that redlines contracts against Legal's playbooks
A full-stack GenAI assistant (Django, Flask) that helps Visa's Legal team redline contracts against their escalation and negotiation playbooks. It started at a hackathon and became a company-supported initiative, one of Visa's first internal GenAI initiatives, showcased at the Q4 2024 RSDP Tech Town Hall. In UAT with the Legal team, the first version cut manual review time by about 30% and found the right clause in the top 3 results about 90% of the time. Later versions helped bring average B2B contract cycle time down 40–50%, from about 4–5 months to 2–3 months across 2024.

new-app setup
Built the Claude Code workflow my team ships with
Standing up a new app on a Module Federation micro-frontend platform used to mean days of hunting down the right steps. I turned that into Claude Code skills the whole team runs, and built the workflow around them: skills that take a work item written in one agreed structure, start the work and publish a pull request for review, plus ADR tracking, spec docs, incident write-ups and knowledge tracking.

Replacing a Tableau product with a real web app
Retail Pricing: Benchmark started life as a Tableau-based analytics product. Our team rebuilt it as a purpose-built web app for real-time, interactive pricing decisions, and the team won a Q3 2026 Innovation Excellence Award for it. I built the .NET 10 API behind it and tuned the ClickHouse queries until its heaviest report came back in 3–5 seconds cold in production.

9 infrastructure docs
plus architecture sessions for onboarding teams
Writing the platform down so other teams could ship on it
As more teams plugged apps into the platform, they kept hitting the same environment problems, from local development through production. I ran architecture sessions for them and wrote the answers down as nine infrastructure docs, structured so engineers and AI agents can both look things up. It earned me a Tech Excellence Award in Q2 2026.

Built a real-time cardholder benefit redemption pipeline
The first real-time benefit redemption processing system between the Visa Card Eligibility Service (VCES) and the Visa Digital Benefits Platform (VDBP). It moves 100K+ cardholder benefit redemption events a day at that uptime.
