Portfolio

  1. Neurobranch v2

    #1

    2022 - Personal

    Revisiting the 2016 idea and reimplementing the idea correctly using modern technology and strong API typing. Instead of creating multiple clients natively, the goal is to create just a web client that can be used as a PWA to have the benefit of offline caching.

    #2

    2022 - Personal

    A sample open source repo for others to use to get started quickly with common technologies via NestJS. The main goal is to cut down on repetitive tasks that I was copying over from other repos instead of just centralising it somewhere that I can keep it up to date.

  5. Github Action - Android Version Bump

    #5

    2021 - Personal

    An automated way to bump semantic versioning using Github on a native Android repository. The version is generated using TypeScript when the action is kicked off on a specific workflow. Using semantic commit messages, the CI run can determine the appropriate version bump to assign to the new release.
    When the job completes, it creates a tag and exports parameters to create a release later in the workflow.

  7. Drink Sense - contextual health insights app

    #7

    2020 - Personal

    Drink Sense is an alcohol health app that tries to reduce harm by contextually showing the effects of alcohol, like Fitbit with exercise.
    The user adds drinks as they consume them, and the app works out state projections and context to aid judgement and consumption insights.
    The API consists of a number of microservices to calculate user timelines, statistics, and health insights meshed together using GraphQL.

  10. GreenFi

    #10

    2019 - Contractor

    Greenfi is an environmental platform for localities in rural Africa to gain access to loans. The idea was to bring in an environment-centric system for repaying a loan in accordance with Sharia Law, as a ledger for a community to implement. The project took about 6 months in collaboration with a designer and clients, and has since sequestered $15,000+ within its first year of launch.

  13. Occup.ie

    #13

    2018 - Startup

    In 2018, it was getting increasingly more difficult to find a place to live in Dublin. The choice at the time was limited to websites such as Daft.ie, Rent.ie, MyHome.ie...and the main problem with those websites was a lack of innovation and accountability, difficulty scheduling visits instead of picking from a calendar, no digital rent agreements, no escrow accounts for securing a deposit, no way to formally define issues to the landlord transparently... The list goes on.
    With my co-founder, we decided to research and play with some ideas and validate them through user hypothesis testing. We also created a quick proof of concept of how we could present these within an MVP. While the MVP was an interesting concept and there was certainly some interest from responses, eventually it became clear that a growing housing crisis would make it too difficult to enter the market with an uneven marketplace.
    Since the goal of the quick research and MVP was to validate and to fail fast, ultimately we ended up failing fast with minimal time and money lost.

    2018 - Startup

    A quick play-project into an easier solution to book hair treatments as a direct competitor to Treatwell.

  19. H. pylori Diagnosis App

    #19

    2017 - Contractor

    This was a contract project for the TAGG group in the hospital Tallaght AMNCH in Dublin Ireland.
    The objective of this app was to move from a paper printout to a digital way of diagnosing the H. pylori bacterial infection. I gathered requirements from doctors who would act as clients in the project, and they would provide guidance at fortnightly meetings.
    Eventually two native apps were released: one on iOS and one on Android.

    DiabetesPlus was another collaboration with the hospital Tallaght AMNCH in Dublin, Ireland. The initial scope of the project was to create a proof of concept for validation in a clinical trial.
    The app was a recommendation engine for users who live with type 2 diabetes and required suggestions to manage their blood sugar levels when exercising. It won a cash-prize in the entrepreneur awards hosted in Cork Institute of Technology.

  22. Trojan horse in a decoy game

    #22

    2017 - Personal

    A proof of concept for trying to execute code on a remote machine. There are three parts to this: the first one is a shell script that snaps pictures of the user and shows notifications. The second part is a decoy snake game that fetches this remote script from a Git repo. The third part is a simple REST API with a flag to invoke or not.
    The remote shell script executes code to run the script via a crontab, making it difficult to remove without some system knowledge.

    2017 - Personal

    Loinnir started off at an Irish-language computer science hackathon in University College Dublin in April 2017 where the goal was to create a solution for the topic "the Irish language around me". I collaborated with an engineer and a business student to create a proof of concept of digital Irish speaking regions. The app was crude, but allowed the user to find speakers in their locality and attend local events.
    Some weeks later, I revisited the idea and created a messaging service where users can form their own communities, grow their locality, and matchmaking users interested in chatting with others.
    At its peak, the service had >550 users, and a 30 day mean-retention rate.

  25. Plynk - Banking App Redesign

    #25

    2017 - Personal

    Back in 2017, I worked briefly at an Irish banking app called Plynk. That is, until they decided not to pay me. I was excited to join, and had some ideas to present to the team in order to make banking more innovative and user friendly. Remember that this was before n26 and Revolut were so large.
    One of the initial projects I did before joining was a redesign involving contactless NFC payments between phones and quick proof of concepts surrounding instant money transfer.
