Billy Joinville

In short

01

I am a software engineer in Miami. Since September 2026 I have been an associate software engineer at Baptist Health, in the Technology and Digital department.

Alongside that I run WebEaze, a small subscription web studio I started in 2024. Forty-odd sites so far, all of them built, launched and looked after by me.

I finished a B.A. in computer science at the University of Miami in May 2026, with minors in sustainable business and communication studies. Before Baptist Health I spent a summer as a data engineering intern at Spotify in New York, and two summers in the IT department of an elevator company in Maryland.

The work

2026 →

Baptist Health

Associate software engineer · Miami

I joined the Technology and Digital department in September 2026, out of university and into the first full-time engineering job of my career. Most of my week goes here.

2024 →

WebEaze

Founder and full stack engineer · Coral Gables

A subscription web studio for small businesses. More than forty responsive React sites so far, plus the analytics, the SEO and the small automation scripts that turn client onboarding from an afternoon into a few minutes.

2025

Spotify

Data engineering intern · New York

A summer on data pipelines. I tuned a daily Apache Spark and Java job that processes partitioned listening logs, cutting its compute cost by 14%, and built a validation step that catches bad streaming metadata before it reaches anybody's dashboard.

I like owning a piece of work end to end.

Work out what somebody actually needs, build it, then stay around for the part where it breaks. That is how WebEaze runs, because there is nobody else to hand it to, and it is the habit I brought with me into a bigger team.

I am comfortable across the stack, from an interface somebody clicks to the script that quietly runs at two in the morning. The parts nobody sees are usually the interesting ones.
