This app is designed to teach students physics using interactive and customizable simulations. It was written in SwiftUI for iPhone and iPad.

The app features several objects the user interacts with, creating unique simulations to learn about equations of motion. For example, the user may explore the motion of brick resting on an inclined conveyor belt, which is itself attached to a moving scissor lift. There are also examples of projectile motion, where the user can throw the brick.

The brick's facial expression animates using a combination of SpriteKit and SwiftUI. The app provides an area where the student can freely explore different objects and configure their simulation.

The app's architecture allows for easily adding and customizing different types of simulation objects and maximizes code reuse to simplify adding future units.

The app includes thorough unit tests and comprehensive support for VoiceOver.

The client provided designs for the app. I was the sole developer and contributed to the physics content. The Development is complete for the app, and it will be released to the App Store once the quiz questions are finalized.

This app is designed to improve how students learn chemistry and help them prepare for their exams. It features interactive simulations, with a quiz after each section.

The app was written in SwiftUI, using UIKIt and SpriteKit.

There are many visualizations, and all are focused around a common beaker. These include a grid of molecules, a macroscopic view with dynamic colors, bouncing molecules, dissolving solute particles, a growing precipitate, etc. The more advanced molecule simulations make use of SpriteKit.

Outside of the beaker, there are several interactive tools, such as sliders, burners, liquid droppers, and scales. There are also containers that move and drop molecules into the beaker in response to the motion.

The app is split into different units, which mirror the AP Chemistry syllabus. It is architected using a separate module for each unit, which helps keep them well encapsulated and easier to work on.

The app uses a tipping model, implemented using both consumable and non-consumable in-app purchases using StoreKit.

Comprehensive unit tests have been added, and thorough support for VoiceOver.

The client provided the app designs, and I was the sole developer. It is available for both iOS and iPad.

The idea behind Wave Writer was to create a high-quality, immersive writing experience. Inspired by voice recording apps that show how sound waves respond to the user’s voice, WaveWriter brings this idea to typing.

A wave at the top of the screen responds as the user types. The animation properties even change as the user types faster or slower, and the wave slowly comes back to the starting position when the user is finished typing.

The wave uses the Accelerate framework to compute the curve, to ensure a fluid and smooth user experience.

There are several carefully designed themes complementing the animation that the user can choose from, for both light mode and dark mode.

WaveWriter was made using Swift and SwiftUI and is available for iPhone.

iManage Extract is an AI platform used by the world's leading law firms to extract essential information from their documents. I worked as a Scala developer, working on the data processing engine for these documents. I delivered massive document processing speed improvements—over 90% in one case—and improved robustness by fixing several memory leaks causing application failure. I was involved in all elements of this product, from planning to implementation, automated testing, manual testing, deployment, and support.

I created a puzzle game for iOS using SwiftUI. The game is based on a graph-theory puzzle called the Dollar Game. I created a novel algorithm to find the minimum number of levels for each level and implemented this using Scala. The cost of calculating the minimum number of moves grows incredibly fast as the game becomes more complex, making these levels unfeasible. My algorithm enabled me to create complex levels where using a conventional brute force approach is impossible.

AnyLog is a flexible logging application made using the Flutter UI toolkit. Users can create custom spreadsheets to keep track of whatever they want.

One of the challenges of designing this kind of app is keeping the UI simple while still exposing many configuration choices.

Storing such flexible data also required careful design of the SQL schema and the codebase itself.

AnyLog has excellent support for screen readers, including the charts tab, where the user can select a data point to hear its value readout with a screen reader.

I am currently rewriting AnyLog using SwiftUI and CoreData.

A Scala client to call Cloudflare API endpoints to manage DNS records. This client was designed to be used as a template for other projects moving forward, serving as the best practices benchmark.

The project includes unit and integration tests and a GitLab CI pipeline.

The documentation is extensive, including both Scaladocs and "Readme" docs.
