Hi, I’m Alex.

I’m your freelance software engineer coder-for-hire, and I’m here to help you build your next big thing, your killer app, your zero to one. I’ve been at this for a long time, twelve years to be exact, and I am ready to meet you where you are and take you where you want to go. Early stage startup or established tech giant, I will work with you and your team to efficiently deliver high-quality results.

I’ve been working with Swift since it was released, and creating interfaces using SwiftUI for nearly two years now. They are essentially my “daily drivers”. Objective-C and UIKit have taken a bit of a backseat for me, but I’ve got loads of experience using both and am quite comfortable with them. Recently, I’ve also worked on and shipped an Android app built with Jetpack Compose. I also have extensive experience with Node.js backends that serve millions of users a month, and know how to deploy and scale these stacks on AWS.

What am I looking for?

I am currently looking for a challenging new project that has real impact. I’m seeking a team that has a great vision with their product, one that I can be a part of and be proud of. Ideally, you’re looking to make something new on iOS using SwiftUI, but I’m flexible on that. I’m also keen to mix it up and work on your APIs or anything infrastructure related. And, if you need a mobile team lead, I’m right there. Currently, I’m based in Berlin. I like visiting an office from time to time, depending on the location, however remote work is a must for me.

Project Work

Founder, Truffle

June 2020 - Present

I created Truffle to solve a problem that I saw often while working at Scout: people ask the same questions over and over in Slack. Truffle uses past Slack conversations and OpenAI’s GPT-4 to build a knowledge base from Slack and answer questions people ask. I’ve gotten great feedback on this project, and I have learned a lot about Elasticsearch, Serverless, and AWS, not to mention tons about marketing, audience-building, and creating customer relationships.

Work History

Mobile Engineer, Freelance

Blinkist. June 2023 - Present

I am working on key components to new features that Blinkist will be delivering in the late summer.

Mobile Engineer, Freelance

Wayfair USA. Sept 2021 - Dec 2022

This project entailed building the mobile components to Wayfair’s physical store experience that launched in May of 2022. We built several features, including a in-app scanner to allow users to look up items shown on ESLs (electronic shelf labels), the ability to pay in the store using their online balance, and an in-store mode for enhanced the customer’s visit to the store.
Additionally, I was part of a team that built an Android app for the employees on the sales floor to set up and edit ESLs. Written in Jetpack Compose, this app was deployed to the Zebra scanner devices used in the retail locations.

Lead iOS Engineer

Scout24 Group. Berlin, Germany. Aug 2020 - Sept 2021

I worked to support multiple teams and stakeholders with their execution, feature delivery, and onboarding of new hires. I had been the Tech Domain Owner for iOS at Scout24, meaning I helped shape the standards for mobile engineering in the company. In this position, I was the lead engineer for time-sensitive projects related to Scout’s COVID-19 response, where we delivered a working high-quality video chat MVP in under a month. When iOS 14 and Apple’s privacy changes were announced, I had been in charge of leading the migration with many stakeholders and engineers. I had also coded quite a bit, as well, working on internal tools, CI systems, and improvements to our automated testing.
I’ve played an important part in architecting and implementing some key features of the Scout24 iOS app, and in moving our codebase from Objective-C to Swift.
