Employment

  • Senior Full-stack Engineer

    2021 - PRESENT
    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 third-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.

Experience

  • 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.
