Tung Nguyen

Senior Software Engineer at EY, New York

I’m Tung, a software engineer in New York. I build backend systems that have to keep working when thousands of restaurants lean on them at once, and on the side I run Pullfolio, a small app for card collectors.

At EY I’m a senior engineer in Technology Consulting. I own the menu configuration and point-of-sale control services for a national restaurant chain with more than 3,500 locations, from API design through production, and I’m the release owner for its core Java and Spring Boot service. Recent work: moving chain-wide configuration from synchronous HTTP to SQS batches with safe retries, narrowing venue menus from 1,300 items to about 130, and cutting P95 latency 65% with Redis caching.

Outside work I’m training for the NYRR Fred Lebow Half Marathon in January. I collect graded vintage Pokémon cards, which is the hobby Pullfolio is built for. Every fall I play fantasy football and take it more seriously than I should. I also build small tools for myself, like a monitor that watches NYC rental listings so I don’t have to.

Email is the best way to reach me. My code is on GitHub, my work history is on LinkedIn, and the résumé has the details.

Years

Four years of backend work at EY, one product of my own, and a lot of evenings in between.

2022

Finished a B.S. in Computer Science at Virginia Tech, on the Dean’s List three years running. Joined EY’s Technology Consulting practice in New York as a software engineer, working on the Java and Spring Boot services behind a restaurant chain’s point-of-sale and menu platform.

2024

Promoted to senior software engineer in December. As release owner of the core configuration service I’ve shipped 18+ releases and same-day hotfixes, and moved chain-wide operations from synchronous HTTP to SQS batch processing, which ended the timeouts across 3,500+ locations.

2025

Launched Pullfolio in August: a trading-card collection app with binders you flip through, price alerts and shareable links. A daily pipeline merges 5 price sources into one catalog of 77,000+ cards and 144,000+ priced variants. It had 5,000+ visitors in its first three weeks.

2026

Released streeteasy-monitor, a rental listing monitor for New York. Kept building Pullfolio. Rebuilt this site twice and moved it to tungthanhnguyen.com.
