As a Hands-on Technical Architect, I define and implement solutions that form part of a multi-tenant SaaS platform. To ensure the successful implementation of solutions by agile scrum teams, I set the direction for the development of new solutions and enhancements to legacy systems by taking responsibility for:• Developing full-stack proofs-of-concept to establish software patterns.• Mentoring and pairing with Developers to spread good practice and knowledge.• Creating a well-estimated and achievable backlog of user stories by working with agile scrum development teams, Product Owners and Product Managers.• Researching, evaluating and selecting new technologies.• Ensuring easy adoption of new technologies, and industry best practice and approaches.• Ensuring that solutions are scalable, reliable, monitorable and maintainable within our 24/7 service to our customers.• Communicate complex functional and non-functional requirements to Architects, Developers, DevOps, CloudOps, Product Owners and Manager.• Document solutions at a high-level using a C4 model and UML and/or BPMN at a low-level.
