Summary

Experience

Jan. 2024 - Aug. 2025

Tech Lead (PIX4Dcatch)

Pix4D (Photogrammetry Software)

As tech lead, I led projects to refactor the app to make it more scalable and apadtable as company needs grew. The app had grown rapidly but now needed a proper strategy to take on new roles. This involved modularising the code and breaking it apart into smaller more manageable packages. I aslo adapted PIX4D's c++ package manager, Conan, to build required binaries such that we could expand the use of our internal c++ libraries. Using our internal CI system, Concourse, and JFrogs Artifactory, the internal libraries could then be vended privately as swift packages using a swift package registry. I also led efforts to improve and expand the automatic testing.

Apr. 2020 - Dec. 2023

Senior Software Engineer (PIX4Dcatch)

Pix4D (Photogrammetry Software)

Developed an AR app from scratch using Swift that PIX4D later adopted. Started as a personal project from soon after joining the company, I started work in earnest in 2019, before it became a full time position in 2020. It was the companies first foray into Swift and I designed the architecture and wrote most of the initial released product. With the embrace of Swift over objective-c I could advance the project rapidly. Using frameworks and protocols such as Codeable, Combine, ARKit, SceneKit and metal. Working with designers to create the UI initialy with Storyboards and UIKit but moving to SwiftUI. As the app grew in scope we would interface with external SDKs for third party hardware. Library management was handled with Swift Package Manager, also including internal c++ libraries with appropriate interop packages. I worked in cross product teams to enable a unified vision across the company.

PIX4Dcatch (https://www.pix4d.com/product/pix4dcatch/)

From prototype to delivery, data capture software delivering ultra precise data for use with Pix4D's set of Photogrammetry software, using the latest Apple tooling for AR and LiDAR. Using Swift 5+ I was able to rapidly build a prototype and evolve it to a working, bug free product within an extremely short time frame, leveraging the latest technologies available in Apple products. PIX4Dcatch has since grown to be one of the key products of the company.

A flight planning app for various drones, Including Parrot and DJI models. A lot of work harmonizing the various SDKs invovled so user could have a consistent experience with any drone we supported. I was mostly working on the iOS version, but we started to llook at a cross platform solution using QT before I started work on catch.
