Hello, I'm Tyvan Cheng

I'm a software engineer with a knack for problem-solving and a passion for creating efficient applications.

My Story

I'm proud to say that I've worn many hats in my lifetime. I graduated from Adelphi University with a Bachelor of Science in Nursing and shortly after began a career as a Cardiothoracic/Surgical ICU RN. For the last 5 years, you could find me volunteering as a firefighter and EMT at my local fire department. Working in high pressure environments, I've developed invaluable skills such as being a quick learner, adaptive and detailed oriented ,and being a phenomenal problem solver.

Why Software Engineering?

My curiosity and knack for problem-solving has always propelled me to discover ways to create innovative solutions. In my free time, I learned how to code and with another developer, built a mapboard that parses through dispatch calls using Google's Dashboard API, ultimately improving response time. I uncovered a world of limitless possibilities and realized the profound impact I could make with my mission-critical analytical skills, passion for innovation, and detail oriented personality.

Projects

A LinkedIn clone using Ruby on Rails and React.js, completed with user authentication, profiles, and full CRUD functionality for posts and comments. Additionally, it utilizes a PostgreSQL as the backend database for efficient data storage and retrieval. I'm currently developing Websocket functionality to allow users to connect in real-time.

Visor is a vanilla JS application that provides a graphical representation of over 8000 stocks' performances over various time frames. Additionally, it leverages the AlphaVantage API and TickerSymbol API to provide real-time and accurate data on various stocks. I'm currently developing a beta coefficient calculator and stock-specific news feed feature for a more data driven user interface.

Experience

- Maintain blockchain indexers, achieving 100% blockchain data integrity through rigorous PostgreSQL validation

- Migrating a beacon chain explorer, pipelining daily Ethereum staking data into Google BigQuery, from Go to C#

- Decrease Cloud Run execution times for Ethereum staking data by over 75% by implementing parallel processing

- Manage and optimize Bitcoin and Eth API endpoints for transactions and positions, ensuring scalable code practices

- Employ multi-threading and caching strategies for the Bitcoin position data API endpoint and consistently achieve sub-30 second response time, reducing AWS gateway timeouts to near-elimination ( less than 1%)

- Currently developing a mobile app, notably with WebSockets and OAuth, to streamline fire department management

- Contribute to website architecture improvements, resulting in a ~25% increase in user engagement with the site

- Construct a map board built with LED controllers and a Python-based email parser integrated with Google’s Dashboard API to display crucial data pre-arrival, improving response time by ~15% over a 6 month period

- Assisted in development of a plasma enterprise’s donor rewards and incentives pricing engine, driven by pricing levers and ML models to achieve an average of a 6% decrease in centers’ cost-per-liter within 2 months of deployment

- Incorporated ETL processes on over 20% of data flowing into the data pipeline for integration with ML models

- Designed a geospatial function to facilitate donation-center location queries based on the proximity to the user’s current location

- Managed critically ill post-operative patients recovering from trauma, open-heart, and vascular surgeries

- Collaborated closely with surgical attendings to develop daily treatment plans on critically unstable patients
