The project was to create a transactional database and all application programming interfaces (API's) to store, retrieve and update user generated data and the surrounding infrastructure in a cloud environment.Pioneered the creation of WS's first cloud based database in the form of a PostgreSQL database in an Amazon Relational Database Service (RDS). Teams first exposure to Amazon Web Services (AWS) and PostgreSQL and required deep dive research in numerous areas, documenting of findings and knowledge sharing among team.This allowed and encouraged the team to try new things and investigate what did and didn't work and to reach out to internal teams for guidance. Collaborated closely with Enterprise Cloud Computing (ECC) to gain invaluable insights into best practices for AWS configuration, continuous integration and continuous deployment pipelines.• Exploratory research and analysis of PostgreSQL.- Main challenge and learning was overcoming transition from autonomous transactions (in Oracle) to transactional functions (in PostgreSQL).• Gained competency of multiple AWS tools and collaborated with ECC on best toolset and implementation for project.- Experience with Amazon RDS, CloudWatch, CloudFormation, Lambda, Identity and Access Management (IAM), Key Management Service (KMS), Simple Storage Service (S3) and Virtual Private Cloud (VPC).• Used Concourse and CloudFormation to create a pipeline to automate infrastructure creation and custom setup per environment and a pipeline for environment deletion. • Used Concourse and Jenkins to create continuous deployment pipelines for non-production based environments.• Documented technical specification documents based off requirements, co-ordinated acceptance criteria with Quality Assurance (QA), development and automation of unit test code, supported QA while testing, and ensured successful promotion of code through environments.• Acted as Agile champion on team that implemented Scrum and Kanban frameworks.

Produced multiple introductory machine learning courses as part of an initiative to enhance learning capabilities. Developed courses covering regression, clustering and classification based algorithms. All courses were half instructor led half video tutorials and Python was the language of choice.• Researched and vetted appropriate content for each course.• Delivered multiple iterations of each course in person and virtually.• Took feedback from attendees and altered courses accordingly.Created an automated unit testing framework for Oracle databases using utPLSQL 3.0. Co-ordinated with technical lead and data architect in the design phase and built out the agreed upon solution. Integrated framework with existing project and expanded the test suite to cover large amount of current work to test advantages and disadvantages in real world application. Project was hugely successful and testing framework was presented to senior leadership team and multiple teams across different businesses and implemented by other teams in the company.• Designed, developed and real world tested an automated unit testing framework as part of a proof of concept project.• Ensured framework followed all best PLSQL unit testing standards and practices.- All tests are isolated and not reliant on any other tests or execution order of tests.- All tests setup any required data to ensure database state has no influence on test.- All tests teardown any setup data to ensure database state remains unchanged.- All test code was treated as first class code and was stored and managed in Git repository.

Developed the backend solution for a near real-time request processing project. The project goal was to provide users with near real-time information on the status' of their open requests and empower them with the knowledge of what is happening each step of the way and if any further documentation or information was required from their end.All request data was collated from multiple source systems at different time intervals (some in real time, some in batch processes) into the staging area. From there complex Extract-Transform-Load (ETL) procedures were executed to combine, analyse and prepare the information to be displayed to a user.• Due to large disparity in the data 'fuzzy' logic was designed to unify data from different sources. - Extensive investigation was required and a multitude of solutions had to be thoroughly tested and ultimately signed off by technical lead.• Huge amounts of daily processed data put emphasis on performance tuning of all ETL's.- Initially worked closely with technical lead to uncover bottlenecks, incorrect use of indexes, poorly performing code etc. And quickly learned how to locate, resolve and avoid these pitfalls.• Designed and documented technical specification documents based off business system requirements, programmed and performance tuned all ETL procedures and developed procedures to expose information.• Manually unit tested and automated unit testing of procedures.- Manual unit testing was the official tests for the project and the automated unit tests were part of a proof of concept project outlined above.• Supported QA while testing, and ensured successful promotion of code through environments.• On-boarded and trained new hires to the team.

Joined Fidelity's LEAP graduate program on the technology track. This is a 6 month program consisting of a 3 month training phase in all essential technical, professional and business skills and a 3 month business sponsored project where a representative from the business acts as the stakeholder for the project.The initial training phase consisted of lectures in: Object Orientated Analysis & Design, SQL & PL/SQL(Oracle), Big Data, Agile Methodology, Unix/Linux, Java, Spring, SOAP & REST web services, C#, HTML5, CSS3, JavaScript and Presentation Skills.Created a big data application which implemented a lambda architecture and followed all of DevOps best practices. The application was an automated framework to find business intelligence by taking data from different sources, analysing and pulling out meaningful information which was displayed in a simplistic way. • Lead the agile methodology within the team and acted as scrum master.• Created and managed the Git Stash repository and used pull requests to conduct code reviews and manage what changes went into production code.• Created the database infrastructure for the team.• Implemented continuous integration i.e. Jenkins to kick off automatic builds and automation testing on the server when a code change was made in the git repository.• Used SpringXD to extract data from log files and insert into Hadoop, hive to transform the data in Hadoop and SpringXD to load the data into an Oracle database.• Continuously facilitated sessions with the product owner to gain feedback and guidance.• Co-presented successful automated framework by means of a live demonstration beginning with a change in the code repository which kicked off an automated build on the server. The unit test suite was run against the newly compiled code. Data was loaded into Hadoop where it was cleaned, prepared and finally exported into an Oracle database where API's were used to display the information in D3 graphs.

• Displayed excellent customer service skills.• Processed payments and provided correct change, switched cash in and out from floats, balanced tills at the end of night.• Arranged staff depending on changing crowds, trained and supervised new staff, stock taking and advising on when to purchase new stock to the bar manager.• Ensured all taps are working correctly and tapped to the correct kegs, fully stocked all fridges, selves and optics and cleaned all equipment and entire premises at the end of every night.

Interned at Fidelity as part of my 3rd year college degree course. Worked on a disturbed agile team based in Ireland, US and China which developed enterprise applications. The goal of the project was to integrate Google analytics with an Internal Application. • Participated fully in the team’s agile methodology attending weekly planning meetings and daily scrum meetings. • Organised code reviews and implemented findings in order to meet the team’s coding standards. • Decomposed large work items into stories and tasks and provided estimates on each task. • Integrated all enhancements into existing 3-tier architecture. • Presented a successful proof of concept to the Galway Development team. • Gained enterprise level exposure to the following technologies; Java, Spring, Maven, XML, HTML, CSS, JSTL and JavaScript.
