Phil Schanely
Full-stack Developer in New York, NY, United States
Member since August 10, 2022
Phil is a full-stack engineer and architect with 20 years of experience taking novel systems from design to launch, whether they are performing natural language analysis for a startup or processing trillions of data updates for Google Maps. Building a successful system is not a purely technical endeavor; Phil's track record is critically supported by his consensus-building skills and thorough comprehension of business objectives.
Phil is now available for hire

Employment
Experience
- CrossHairhttps://github.com/pschanely/CrossHair
I created CrossHair to help people confirm or deny Python program invariants. CrossHair models the Python semantics in a formal language that SMT-based theorem provers can analyze. It is noteworthy that CrossHair's announcement reached the number one slot on Hacker News.
- Music Tonighthttps://musictonightapp.com/
Partnering with Songkick and Spotify, Music Tonight makes playlists of artists playing near you tonight or up to two weeks in the future. I designed and built the entire system: an AngularJS front end, a Node.js back end, and a MySQL database.
- EmojiTacticshttps://immadeofmeat.itch.io/emojitactics
EmojiTactics is a simple turn-based strategy game. It also has a curious property: every graphical element in the game is an emoji. I built EmojiTactics fully on my own using regular old JavaScript.
You can read about the adventure at medium.com/p/db480ace2eb3. - ScoreDBhttps://github.com/pschanely/scoredb
ScoreDB is a database designed to order results by custom scoring functions written in Go. Phil designed the system and wrote most of the code. Scoredb uses a format on disk that is very similar to that used by text search systems like Solr and Elasticsearch but outperforms these systems when using dynamically supplied scoring functions.
