I worked with Wagestream on the redesign and replatforming of their mobile app from jQuery to React. As the only experienced developer on the team for some time, I guided others and helped onboard further engineers. Over this period I rewrote much of the app, implemented a bunch of new features, replaced a retired code delivery pipeline, and fought fires as needed.Working with an unmaintained codebase, I reverse engineered the expected behaviour, uncovered forgotten requirements, and built replacements in React following a strangler pattern to carefully and successfully replace the app. Technology used includes: React, jQuery, Typescript, Fastlane, Cordova, GitHub Actions, Postgres, Python and AWS.

Working to guide a team of developers to design and implement critical features for the company's major product. The majority of the code is in C# with browser applications written in Typescript. Work involved discussions with PSO, product owners as well as customers to gather requirements and develop a solution that provided the required features in a succinct, customer centric way.

I was hired into this role to manage a team of developers to transform the company's legacy backend application to a modern serverless solution built on AWS and utilising modern microsevice and RESTful practices. The company operates in the Free-to-Play game market and with a large player base there is a lot of data produced every day. Using tools such as Kinesis and Redshift to process and operationalise large quantities of data.The role involved every aspect of the project, from discussions with the C-level execs, and board, through requirements gathering with end users and architectural design, down to development and deployment.

HIMEX went through a rebrand the Founding CTO exited and I took over full responsibility for all of the technical side of the business. Continuing to improve the platform and add features to help market it. The company attempted to pivot into fleet software as the UBI market heated up and they didn’t make the sales they hoped. However with investor issues, the company went into life-support and within days of me resigning shut down the business line, due to lack of growth.

Having quickly proven my ability, I took over fully technical responsibility for the core platform and the mobile API. I hired in multiple engineers to support me to rebuild the product, resolve a lot of the bugs, and add new features. I rebuilt using Spring Boot that allowed us to follow a microservice architecture, using HAProxy, for routing of requests on a high availability API. I was responsible for all management and running of the entire system, from design and architecture to deployment and operations. I visited customers (some of America’s largest insurers).

Dundee

Creating a platform and mobile app for HIMEX’s Usage Based Insurance technology with 3 of America’s top 10 insurance companies as customers. As a small startup, I was brought on to take over the core platform from the CTO, improving the reliability and adding new features. Initially I reconfigured the build process to use Maven over the manual deployments. Then I introduced RabbitMQ to provide resilience to the communication features over the first few months with the company.

Worked on the GFI Cloud ITSM project that had a GWT (Java) frontend and a PHP backend on top of a MySQL database (a typical LAMP stack). Worked on a project to add web monitoring and filtering the the feature set.

Originally working on the mobile banking solution that allowed for online banking applications to be supported by a full range of mobile devices, in 2011, this was quite heavily focused towards feature phones with WAP and GPRS, and even SMS as a fallback. This was all achieved through a collection of adaptive components that could render appropriately for the device based on User-Agent string. The main tools were Spring Framework and JSP.With the recent release of smartphones, I pivoted to work on an R&D project for Mobile Cash Withdrawal. This product would allow a user to scan a QR code displayed on an ATM and withdraw cash without the need to have their bank card on them. I built the server side implementation of this from the ground up, implementing a RESTful web service with Spring Framework, and using XMPP for pushing notifications to clients. I had RabbitMQ as the message queue and LDAP as the identity provider. The database used was a Postgres DB. This architecture allowed the solution to have the high throughput required, and with some careful tuning of the Postgres database I could achieve the 250k concurrent user requirement. I even picked up a US Patent during this project (US8,925,829B2).

Taking on a lead role for one of our clients, as well as mentoring junior staff. I worked directly with the client to gather requirements and implement change. My strong performance recognised through a freedom to work directly without supervision, and this subsequent promotion.

Working on feature development for Airline clients of the SITA e-Commerce Platform. The platform is a large J2EE application originally built using SOAP and JSP, which we migrated to Apache Velocity templates and a new RESTful web-service along with JavaScript for an improved user experience. The underlying database was an Oracle DB.
