I am a passionate and versatile technology professional with a consulting background and proven ability to engage with customers in all phases of the software development lifecycle. My experience covers a broad range of roles including software engineering, support, service delivery, project management and customer success which allows me to provide both strategic leadership and technical expertise. I am a persistent problem solver with an insatiable appetite for learning, and I am always working to expand my technical skillset.

I have a strong personal interest in aviation, including solo flight experience. I've always been fascinated by the complexities of aviation operations and I hope to one day obtain my pilot's license. For now, I satisfy my interest through MS Flight Simulator, listening to live ATC communications and tracking flights from the passenger seat! (It's always important to know which SID/STAR you'll be flying en route to your vacation destination!) I also enjoy personal finance/investing and have recently experimented with algorithmic trading.

Key tools and technologies I have experience with include but are not limited to: Java, Python, Vue.js, Spring/Spring Boot, RDBMS (MSSQL, Oracle, MySQL), GitHub, REST APIs, XML, HTML, CSS, Postman, Windows, Linux, Splunk, JIRA, Eclipse IDE, VS Code, IntelliJ, AWS, Microsoft Power Platform

Projects

Airport Briefing API

The purpose of this project was to gain exerience building APIs using the Spring Boot framework. Since the project was for learning/fun, I built the API in one of my key areas of interest: aviation. The API accepts one or more comma separated airport identifiers via the "identifiers" URL parameter and returns data in JSON format about the airport's facilities and current weather conditions. The API uses two third-party data sources: one for airport/facility data and one for weather data. The program makes secondary API calls to each of these third-party data sources and then aggregates the relevant data into a single JSON response, referred to as an "Airport Briefing", which a pilot would obtain when flying into or out of a particular airport. There are a number of additional features I would want to implement in order to make this API "production-ready". For example, in order to improve performance, I would want to make the third-party API calls run concurrently and I would also want to implement some form of caching to reduce the number of third-party API calls. I would want to improve on the standard exception handling functionality to make the API more descriptive and resilient to specific exception scenarios that could occur. Finally, I would want to implement some additional user configuration options, such as the ability to request a specific number of weather forecast periods and to control which data fields are returned in the response body. This was another fun project that I love to talk about, especially considering it involves aviation!

Tools and technologies used in completion of this project include:

  • Java - Spring Boot
  • Maven
  • IntelliJ IDE
  • AWS - Elastic Beanstalk

Algorithmic Trading Application

I continue to iterate and work on this project for fun with the purpose of practicing my python programming skills, gaining exposure to algorithmic trading, and potentially earning some profits along the journey! I came up with a simple algorithm which runs each day and buys and sells if certain criteria are met. Trade signals are generally based on the RSI technical indicator and daily percent up or down of a given symbol. Trades are made through the Alpaca API-first brokerage platform and tracked in a simple MySQL database. The application and database run on the PythonAnywhere platform. I generally stick to a long-term, buy and hold investing strategy, but this was a cool way to experiment with some short-term trading strategies.

Tools and technologies used in completion of this project include:

  • Python
  • Python-Dotenv
  • Anaconda PythonAnywhere Platform
  • Alpaca.Markets API
  • MySQL
  • VS Code IDE
