Skills
I'm offering
I have 20 years' experience working as a developer, scrum master and development manager for several large organisations the financial sector. My primary technology stack for several years was server-side Java (J2EE and then Spring). I also have a lot of experience using JavaScript, including most recently a lot of projects using Node/React. I am a great advocate of using public cloud infrastructure and automated, scripted deployment and have used various providers (AWS, Azure, OpenShift etc.) in my professional work and in hobby projects. I have a great deal of experience working in and leading agile teams. I believe in focussing on the principles of agile development (collaboration over specification; transparency; incremental delivery and improvement; empowered teams etc.) rather than any specific process or tool. Over my career, I have held a number of different positions, from Developer, Tech Lead, Scrum Master, Delivery Manager, and Programme Technology Lead. I have found that am happiest and most passionate about my work when I am involved in hands-on development across both front- and back-end.

Senior Full-Stack Developer (React & NodeJS)
unknown.
For this role, I returned to work with 101 Ways at their client Trussle, UK's leading online retail mortgage broker. I
worked as a full-stack JavaScript developer across their Growth and Platform technology teams. This has turned out to be a much shorter engagement than I expect as the new CTO has decided to end the company's relationship with 101
Ways.
Technical Environment
NodeJS, ES6, Typescript, Express, AWS, Kubernetes, Docker
Key achievements
Full lifecycle (analysis of requirements with business representatives, story grooming and estimation, development, test, release, support) of features
Improved some NodeJS microservices by removing the tight-coupling caused by the exporting of libraries that
connected directly to the database, by exposing instead an HTTP api
Wrote a NodeJS lambda to periodically reconcile data from two sources (google spreadsheet content overview documentation and the Contentful CMS api) and send notification email to the content team if they diverge
Refactoring a NodeJS/Express application server (and SQS message consumer) for improved testability and type-
safety
