Work Experience

Senior Software Engineer

2021 - 2024
BitAlpha, Inc.
  • Designed and implemented a secure authentication platform to streamline our client experience across multiple identity providers and applications.
  • Led the adoption of TypeScript across our codebase, migrating the entire legacy system by creating custom abstract syntax tree (AST) tools used by our entire team.
  • Integrated our systems with several new blockchains and implemented a new generic integration tool to increase our efficiency when adding new integrations in the future, ultimately driving more sales.
  • Monitored and responded proactively to system outages and live incidents, providing rapid intervention at all hours to keep our systems operational.
  • Developed and implemented event-sourced designs for some of our most critical business models and systems.

Senior Full-stack Engineer

2021 - 2021
Paypa Plane
  • Designed a new OOP architecture for the company's Node.js services in TypeScript, resulting in a dramatic decrease in runtime errors.
  • Created a new system for routing messages between different microservices using an event bus and gRPC. This increased the system's resilience significantly.
  • Designed and implemented an integration with various 3rd-party providers and Australia's financial regulator to bring customers new banking features consistent with ISO standards. This system is now used by some of Australia's largest banks.
  • Broke down an existing monolith back end into event-driven microservices, utilizing CQRS and Protobuf (gRPC) for communication.

Senior Full-stack Engineer

2018 - 2021
Timetabling Solutions
  • Built a new application from the ground up that greatly improved the way clients view their school’s timetable. This app is now sold as part of the company’s product suite and generates a strong revenue stream.
  • Designed an algorithm to automate and optimize our client's staffing requirements. This was an evolutionary algorithm that quickly produced results similar or better than a human operator within seconds.
  • Modernized the front-end workflow by implementing TypeScript, ES6 features, and dependency management through webpack and Yarn.
  • Managed the project with a team of three other developers to fix bugs and improve code quality.
  • Led a server-side scale-down project to reduce costs in light of decreased company revenue during COVID-19. This project involved extensive application refactoring and delivered an almost 75% reduction in Azure fees, with almost no client impact.
  • Homogenized the company's product suite through a shared front-end platform, utilizing dependency injection for core logic. This delivered a much better user experience to our clients, as each application worked consistently.

Networks and Security Engineer

2016 - 2018
Telstra
  • Played a key role in managing the deployment of ADSL to all traffic lights in the ACT.
  • Acted as a networks and security engineer on a first-response team for a multinational company affected by a ransomware attack. Developed a recovery plan and implemented preventative measures.
  • Developed internal productivity tools in Node.js to automate report generation that was previously compiled by hand.
  • Designed, implemented, and sometimes installed secure networks for Telstra's business customers, primarily using Cisco and Cisco Meraki technologies.
  • Contributed to the rollout of secure internet for a multi-million dollar government contract.

Developer

2015 - 2016
Freelance
  • Developed an ERM web application for a fabrication company that automatically provides its clients with accurate quotations and manages internal fulfillment of orders.
  • Built automation tools in VBScript for a real-estate company that improved their data management workflow.
  • Created a web scraper that gathers valuable data for a social media company.
  • Developed a site for a university research team that allows them to interactively display the results of their research and easily compare it to the findings of others.

N-body Planetary Simulation in the Browser

https://protango.github.io/Web-Orbits/
An entirely front-end application developed in Babylon.js. This is a sophisticated N-body simulation designed to simulate accurate gravitational interactions between a large number of celestial bodies when paired with capable hardware. The project utilized several advanced and emerging web technologies to achieve the required performance, such as WebAssembly, WebGL rendering, and the GPGPU features of WebGL. I developed this solely for professional development and is now available as an open-source project on my GitHub.

Timetabling Web Application for Teachers and Students

Led the development of an application designed to allow both teachers and students to view and manage their school's timetable and subject preferences. This application was developed with an ASP.NET back end and an Angular (TypeScript) front end; all hosted on Azure. This app's reliability was critical due to the nature of how it was being used, and I worked on extensive load testing and optimization to achieve those targets. During peak season, the app would see millions of requests every hour.

Microservice-based Migration of Payment Systems

In response to growing demands from clients, I helped design and build a new, event-driven microservice architecture for a complex payment platform. The platform focused on strong scalability and reliability, as it was to be used by large corporate clients.
