Performance optimization, reverse engineering, etc.Highlights:- Co-created the widely used Eisel-Lemire algorithm: fastest-known algorithm for parsing floats from strings, now used by the Rust standard library, FastFloat, and more.

Was used for 2+ years for all builds at Uber, Facebook, Spotify, etc.- Wrote widely-used, 3x+ speed replacement of main Swift JSON parser in Swift and C++ (https://v.ht/zippyjson). Used in production at GitHub, Airbnb, etc.- Reduced incremental build time for iOS apps by ~10% by discovering 2 new code signing tricks (https://eisel.me/signing). Used for all builds at Uber, Facebook, Spotify, Lyft, etc.- Discovered way of reducing download size for iOS apps by 35% by preventing Apple from performing wasteful and ineffective pre-compression encryption on app payloadGithub - github.com/michaeleiselBlog - eisel.me

- Wrote most of company's main production offering: a Rust-based, GPU-accelerated CLI tool to generate financial risk models for quants- Used linear algebra tricks and custom C++ CUDA kernels to speed up initial prototype by 20x- Built out financial factor data pipeline for Python and did research in Python (NumPy, pandas, PyTorch)
Santa Monica, California, Us
- Led the development of the iOS performance testing product, allowing companies to get statistically sound results for each PR as to whether it improved/regressed the performance of any of their key metrics. Also wrote a blog post related to it: https://www.emergetools.com/blog/posts/improve-popular-iOS-app-startup-times- Created the iOS client-side SDK for Reaper, a service which can determine via runtime analysis which classes are unused in an app and can safely be deleted.- Created a backend service which symbolicates addresses from system libraries in crash reports, and which can be used by anyone via https://emergetools.com/symbolicate
Stockholm, Stockholm County, Se
- Reduced incremental build time for the main iOS app by ~25%- Reduced app download size by 19%, along the way finding a more size-efficient way to package localized strings (eisel.me/localization)- Migrated the Stations app to the Bazel build system

iOS development and product managementHighlights:- Replaced with Crittercism with Crashlytics for iOS app's crash logger. This was a 6-month project management effort that included leading the contract negotiations and building out new tooling. The result was a higher rate of caught crashes and symbolication of all threads for each stack trace.- Wrote the linter for the iOS code base and integrated it into the CI system. It included both custom lints and lints from the clang static analyzer.- Wrote a high-performance logger in Rust for debug messages, including a full rewrite of +[NSString stringWithFormat:]. This improved startup time of the app by 10% for internal tester phones, as well as a number of other metrics.- Wrote an HTTP loop back server that allowed for custom precaching of .TS video data. Snapchat subsequently filed a patent for it.
