Denver, CO · Engineering + leadership

Matthew McQuillan

Hands-on engineering leader — APIs, quality, and teams that ship.

Portrait of Matthew McQuillan

I keep scope tight, ship to users, and coach people so the team’s collective intelligence does the work. The J.D. still shows up in how I think about contracts, risk, and client communication.

01

Selected impact

Work that shows both delivery and judgment — architecture, quality, and the decisions that protect a release.

~$500k

Licensing cost avoided

Adapted a document generation service to a legacy system on a compressed timeline, including automated deployment to Azure containers, resulting in nearly $500,000 in licensing savings.

5% → 20%

Quality and observability

Raised unit test coverage from under 5% to nearly 20% and added a full OpenTelemetry pipeline in Azure Application Insights for logging, tracing, metrics, and alerting.

Award-nominated

Release integrity

Prevented a premature release when the constraints were high. Nominated for a company award and appointed to an internal panel tasked with process improvements.

DACPAC → Flyway

Migrations and proofs

Moved schema management from SQL Server DACPACs to Flyway; built JSON schema generation for a distributed API architecture; and delivered an F# event-log proof of concept with spec-driven development.

How I work

I treat leadership as coaching: help people thrive, support teammates, and make room for diverse expertise. Execution still matters. I prefer focused scope, rapid delivery, and learning from what users actually see.

Hands-on work stays part of the job. I design APIs and schemas, care about test automation and observability, and will still sit in the code when that is the fastest path to a good decision for the team.

Expertise

Depth where it changes outcomes — not a catalogue of every tool I have touched.

API contracts that last

Uniform, maintainable schemas so new endpoints share a contract instead of becoming special cases.

Event-driven systems

F# and .NET services, Postgres-backed feeds, and architecture that can move from legacy to evented without theatre.

Quality you can see

Test automation, OpenTelemetry, and the judgment to hold a release when the constraints are high.

Coaching leadership

Intake, delivery health, and a culture where specialists across product, ops, and engineering do their best work.
