Dallas, TX · Senior full-stack engineer

Tyler Green

I was the user before I was the engineer.

The pivot

Six years selling. Then I learned to build.

I spent the first six years of my career on the revenue side of software. I sold cars at Sewell Lexus, carried a $2.4 million book across 6,900 accounts at DealerSocket, advised CIOs at Gartner, and ran two of my own businesses. I learned what a number on a dashboard costs the person who has to hit it.

Today I lead a greenfield React 19 dashboard at StoneEagle F&I. The business background never became a footnote: it is why I start from the outcome and work backward to the architecture.

The code that makes money ships in production at the companies I work for. The code you can read is this site.

The proof

I built it for one user. Me.

The pandemic sent wholesale car buying vertical. CarOffer went from roughly 3,000 transactions to 30,000 in a few months, and the internal tools were built for the old numbers.

I was an account executive then. The page that returned a vehicle history had no deep link. Load it. Wait 45 seconds. Paste a VIN. Wait again. More than a hundred times a day. So I built myself a shortcut: copy a VIN, land on the record.

One afternoon the VP of sales was at my desk for something else and watched me use it.

“Everybody has to have this.”

That meant learning to ship to other people. I gave it an auto-update, so every copy patched itself whenever I released a change. Within two months it was running across the company.

Then I asked CarOffer's engineering team for a shot and set the terms myself: a pay cut, reassessed at 90 days. They called it at 60 and made me an engineer.

Nobody assigned that work. That part has not changed.

Work

Where I have shipped.

StoneEagle F&I

Software Engineer, full stack

2026 to present

Ext JS monolithReact 19 + TypeScript on cached Postgres APIs

Lead the greenfield dashboard replacing a legacy Ext JS frontend on a multi-tenant retail analytics platform: widget architecture, cross-device persistence with shareable links, and the reliability fixes that unblocked a gated pilot rollout.
Build the reporting endpoints behind it: PostgreSQL aggregations with window functions and pivoted datasets, plus a dataset cache so sorting, filtering and paging never recompute an expensive pivot.
Ship across the worker and event tiers too: queue-driven generation and delivery of scheduled reports, event publishing that syncs permissions between services, and retry-hardened upstream calls after transient failures left filter lists empty.
Built the automated quality layer: a Playwright suite that runs every report across both data backends and diffs a scoreboard run to run, and a k6 load harness with per-endpoint latency dashboards in Grafana.
Shipped the data-hygiene feature that shows dealers revenue arriving unmapped and uncounted: a live warehouse integration held behind an anti-corruption layer, and a tenancy fix so client-level users see every dealer rather than none.

2026 highlights

CarOffer

Software Engineer, a CarGurus company

2021 to 2025

Built the Insights Dashboard end to end: C# and .NET APIs aggregating Elasticsearch data behind SQL Server, surfaced through a React interface.
Designed Matrix Analyzer so sales teams could see the real-time effect of configuration changes, lifting platform-wide offer generation 28%.
Shipped the Automated Rules engine for policy-based buying, tripling rule approval rates and removing hours of manual work each week.

Before code

Sales leadership and ownership

2013 to 2021

Sewell Lexus: earned the Team-Twenty Presidential award twice at 150% of quota, with a 98.6% customer satisfaction index.
DealerSocket and Gartner: managed $2.4M across 6,900 accounts, then advised CIOs on enterprise strategy and added $90k in recurring revenue in four months.
Owner-operator of two businesses, and an account executive at CarOffer managing 100 dealerships before moving to engineering.

Stack

Tools of the trade.

TypeScript React C# .NET Core PostgreSQL SQL Server AWS Azure Docker Playwright k6 Grafana Vite SCSS Redis Elasticsearch Snowflake

Darker weight is where I have shipped production systems. React, TypeScript and PostgreSQL are today's daily drivers; C# and .NET carried four years of API work before them, and that is where I want the next four.
