Hello,

My name is Pachito Marco Calabrese, but everyone calls me Marco. I'm a software engineer at Apple in Copenhagen with a background in telecommunication engineering. I love building things where web technologies meet the physical world — from IoT platforms to Bluetooth-enabled devices.

01. Experience

Copenhagen — February 2019 - Current

Software Engineer, Apple Inc

Confidential

Copenhagen — September 2016 - October 2018

Senior Frontend Engineer, bolighed.dk

Led frontend engineering for Bolighed's "Business Manager" — an analytics platform used by banks and real estate professionals to track market trends and property data.

Architected and built the frontend in Angular 4 with TypeScript and Bulma, while collaborating closely on API design with the Django/PostgreSQL backend team. Drove performance improvements and scaling strategies as the user base grew.

Prototyped and shipped a new high-performance frontend that now powers www.bolighed.dk.

Senior Frontend Engineer, www.simplesite.com

Engineered, developed, and tested SimpleSite's next-generation web app builder, serving 6 million users worldwide.

Led a frontend team of developers, designers, and engineers — coaching the team on modern workflows, tooling (Git, Gulp.js), and best practices. Built the app with AngularJS 1.5, TypeScript, and Foundation 5.

As part of the Growth Hacker team, ran extensive A/B tests and analysed user behaviour data to drive product decisions and increase conversion rates.

Copenhagen — July 2013 - April 2015

Frontend Engineer, NOCOPO A/S, www.comparo.dk
