Software Engineer

Started the TypeScript refactor of Mantle, beginning with the order-management ('mantle-orders') by contributing to building its core flows, order confirmation, product-collection explosion, EBA/FRONTLIST credit order, and Action Summary, on HAPI.js v21 with Awilix for dependency injection and Objection.js (with Knex.js) for the ORM layer, and Jest for unit testing.
Contributed to building the 'mantle-fulfilments' SAP and A2R processes, IFC134 XML over SFTP for book orders, A2R CSV file generation, the SAP business-partner REST proxy endpoints, and the order-credit process.
Contributed to the creation of Lambda functions for the refactored service (using Node 18, AWS SAM, Awilix, TypeScript, and Jest), applying a tag-driven (or event-driven) architecture to decouple the domain logic from the transport layer, and using SQS as the event bus for inter-service communication.
Added the IDM identity proxy and product-search modules to 'mantle-backend', and shipped the 'entitlement-cancellation' endpoint.
Wrote the foundational service code for the new service 'mantle-ledgers' (using Fastify 5).
Replaced the team's Fuge local-dev stack with Docker Compose and AWS Localstack setup that boots all Mantle services and dependencies (including the localstack SQS queues) with a single shell script.
Wrote the team's current Claude Code SDD/TDD configuration (docs, rules, skills, agents, AGENTS.md, CLAUDE.md) to improve the developer experience with the new AI-assisted workflow. Ongoing development and improvement of Claude Code configuration is part of my responsibilities as the team's 'Claude Code SME'.

Junior Software Engineer

Maintained Mantle's legacy stack, a JavaScript, Hapi.js, NATS-Hemera microservice platform covering negotiated-sales orders for academic books and journals, patching bugs and shipping small features against JIRA tickets.
Implemented a SAGA-pattern flow in 'order-service' for order cancellation and 'set order to live', and shipped fixes for journal sales-model ratios, customer price overrides, and the GOBI 'Error checking PO' issue.
Implemented sales-rep UI changes in the legacy web (Nuxt 2, Vue 2, Vuetify), added PO-reference validation rules, set the 500-character limit for the order-comment field, and applied copy/plural fixes on the order details form.
Also worked across legacy Hemera services ('gobi-listener', 'a2r-service', 'comment-service', 'identity-service', 'usage-service'), added 'ILR and IXD' filters for journals, and fixed the 'customer does not have SAP BP' issue in some GOBI orders.
Operated within the Agile process (daily standups, refinement sessions, sprint planning, and retrospectives) and MR/peer dev-review workflow.

03 — Training

Goodfrontend.dev

September 2021 — February 2022

Completed an intensive frontend development cadetship progressing through structured individual and team-based project phases focused on modern web technologies and real-world collaborative development.
Built proficiency in Next.js, React, and TypeScript through structured projects including a comparative code review of 6 different implementations to evaluate best practices.
Improved CSS skills in Flexbox and Grid, culminating in a team-built CatWiki app integrating Apollo Client/GraphQL with the Cat API.
Contributed to the Goodfrontend.dev live website as part of Team Maki — a 4-person team — taking on tech lead responsibilities, learning Contentful CMS, and writing GraphQL queries.
Navigated team challenges including Git workflow conflicts and unclear task prioritisation — resolved through code refactoring, role clarification, and self-organised standups.
Transitioned from solo academic projects to structured agile team collaboration, building practical experience in role flexibility and peer accountability.
