Ellis James, Curriculum Vitae

I’m an experienced Software Engineer with 8 years in the industry. Using JavaScript, HTML, and CSS for 16 years. In my last place of employment, I was using TypeScript daily. But I’m currently looking to start working with Go professionally. I have experience in designing and proposing solutions for user interfaces, databases, and infrastructure using top-down and bottom-up approaches. I'm comfortable with servers, SQL databases, backend, and frontend. I can work autonomously but love working with others, and as a team.

Worked on TypeScript and PHP microservices and TypeScript/React frontends, part of the squad which worked on the Core features of the new platform. Services were deployed via Kubernetes using EKS on AWS or AKS on Azure using Terraform to provision infrastructure.

• Redesign the database and reimplement the backend and frontend ton control feature groups or individual investors access to opportunities. Added flexibility for whom we restrict and allow based off attributes associated with an investor such as their ID, Classification, and Group and make it simple to add new attributes such as Location which were on the roadmap.
• Writing migrations to copy and transform client data from the monolithic legacy platform database and to the microservice databases.
• Design the database and implement the backend and frontend for a new Access Control feature to give Opportunity Managers the ability to decide what features an Entrepreneur User had access on a Per-Opportunity basis for Entrepreneur Opportunities.
• Design the database and implement the backend and frontend for a Feature Flag system to be able to turn features on and off on a per-opportunity basis and the ability to set default settings on a platform level.
• Diagnose and fix high priority issues when they arose in Pre-Production and Production platforms.
• Refactoring React frontend components so we could put them into our UI library to reuse them throughout our frontends.
• Writing code and types which could be shared between the backend and frontend.
• Refactor and write frontend components and utilities with internationalisation in mind, such as utilities for date time conversions from UTC to the client's local time and back, and components which handle date time conversion automatically.
• Add Full Text Search for all user content created in a Social Network (Facebook/LinkedIn) area of the Platform. Content was filtered out or in content based off the user's role and posts in groups that they are member of.

In mid-February, Care Direct became its own company and I chose to move there from 21:32

• Fully automated deployments for the backend using BitBucket Pipelines, AWS CodeDeploy, and AWS Secrets Manager
• Designed the backend and wireframe frontend for a system to monitor and support users. The system was envisioned to handle SOS Alerts from various devices and assigns them to Monitors for investigation. Monitors could access sensor data, view cameras, and alert emergency contacts or services as needed
• Designed the backend and wireframe frontend for a call centre feature for Tunstall using WebRTC and our existing TURN server. The system was envisioned to allow for both inbound and outbound calls between users and the call centre, depending on the user's status. This was going to leverage our app's video call infrastructure

• Worked on dashboards for all our products from a monorepo. Introduced automated deployments for the frontends
• Set up restricted Wi-Fi networks to enable app downloads from Apple and iOS Stores. Most robust solution involved creating our own DNS Server for the restricted network
• Sourced ZigBee hardware including various sensors (ie. Passive infrared) and SmartPlug, as well as Wi-Fi-enabled cameras from China for remote control and streaming
• Designed and implemented databases, APIs, and web frontends for both a camera system and a ZigBee-based sensor network. Camera features include user assignment, HLS streaming, and MQTT control. For the sensor network, I built the backend to process data from ZigBee Gateway to our MQTT server and database, and developed APIs for frontend display
• Heavily involved with Care Direct setup on AWS, such as setting up the servers, databases, software, AMIs, and domains
• Helping refactor the backends from Koa to NestJS

• Collaborated with a colleague to develop and maintain iOS, Android, and Web apps for various subjects
• Implement the translation of an app into Welsh in partnership with the Welsh Government
• Redesigned apps for smartphone compatibility, expanding our user base beyond tablets
• Created wireframes and prototypes, incorporating feedback to enhance app designs
• Implemented a streamlined framework for converting content such as posters into responsive webpages
• Designed and built websites for app promotion
