Tangential is a startup I founded where the main product was an AI tool that analyzes information found in Jira to help technical leaders get better visibility on the projects they manage. Managers can automatically perform analysis on projects defined by a JQL query, and a text status summary is generated for each epic in the project. A dashboard built using Next.js and Tailwind CSS allows managers to see the status of all projects at a glance.

I built the frontend and the backend using Serverless, Node.js, Typescript, and GPT-4, and it works incredibly well to understand where projects currently stand and what the risks are that need to be mitigated.

Report writing is also made far easier with Tangential, as it can write status reports to be sent to stakeholders, tailored specifically to target audiences. For example, a report can be generated for a CTO that focuses on the technical details of the project, while a report for a product manager can focus on the business value of the project.

I worked with a cofounder to develop this tool, and wrote about it here: Tangential Reflections - Our AI Product Journey

The code is open sourced and available on GitHub:

Encamera is an encrypted camera app build completely in Swift and SwiftUI. Think of it like Signal for your camera roll.

I recently worked with a design partner to redesign the app from the ground up. We focused on making the app as simple as possible to use, while still providing a high level of security and privacy.

To gain more trust, the source code for file handling and encryption is available as an open source project

as EncameraCore on GitHub.

Currently available on the App Store.

Blinkist is a subscription based service that provides summaries of non-fiction books.

I worked with the Blinkist iOS team to develop a new reader/player for the Blinkist app, which was a greenfield project built in Swift and SwiftUI.

This new reader/player was designed to be more engaging and interactive for the user, allowing users to read as well as listen to the audio version of the book, highlighting text and playing audio as the user reads along.

Built a set of key features needed for the launching of Wayfair's first branded physical store locations: AllModern and Joss & Main.

This enhanced in-store experience allowed users to scan QR codes on products to view product details, add products to their cart, and checkout.

The consumer facing app was built in Swift and SwiftUI, and was designed to be used by store associates to help customers find products and place orders.

I also worked on building the associate facing app, which was built in Kotlin and Jetpack Compose and used a GraphQL API to communicate with the backend.

Truffle is an AI powered Slack app that uses your Slack conversations to generate documentation and answer repeated questions. Built as a side project during Covid-19 lockdowns, I turned it into a full-fledged business in 2023, and it is now used by over 60 companies.

Truffle is built on a serverless architecture using AWS Lambda. It uses a trained BERT model to create embeddings of GPT-4 summarized Slack messages, and uses those embeddings to find similar messages and generate documentation. RAG (Retrieval-Augmented Generation) is used to generate responses to questions.

Check out Truffle website for more information.

I worked at Scout24 as a full time employee from 2016-2021, as a senior iOS engineer and then as a lead engineer. I helped deliver many new features for the customer experience team, including a new map view, a new search experience, and a new listing detail page. I also worked on the backend team, building new APIs in Node.js for the features we were building in the iOS app. We were able to deliver performant microservices that were able to handle the load of millions of users for the new home feed experience that still exists in the app today.

I was also the iOS lead for the Tech Domain Organization, which worked to set standards and best practices for the iOS team, and to help mentor and onboard new engineers. Working with my Android counterpart, along with the design team, we planned and implemented a standard design system that was used across platforms, allowing the app to have a consistent look and feel. This involved agreeing on components with both designers and engineers, and gradually replacing one-off components that had existed in the app for years.

Sonntags is a React Native app for iOS and Android that uses OpenStreetMap to show users nearby stores that are opened on Sunday. I was inspired to build this app after moving to Germany and finding out that most stores are closed on Sundays, though there are a few exceptions. This app uses OpenStreetMap data to show users on a map which stores are opened on Sunday, and allows users to filter by category.

Available in the App Store
