Tom Fleet
Senior Software Engineer
About
Experienced Software and Platform Engineer with a background in aerospace engineering and materials science. Strong expertise and experience in microservice architectures and supporting infrastructure. I take pride in producing reliable, clean, robust and well-documented software and architectures. I also enjoy mentoring other engineers and sharing knowledge/experience in areas where I'm able to do so. I enjoy learning new things and have a lot of side projects! Everything from command line tools to mini programming languages to build systems, parsers and reusable libraries.

Senior Cloud Engineer
Senior Cloud Engineer in the platform team, designed, implemented and managed crucial parts of the AWS estate as well as other shared infrastructure/services in a more DevOps and DevEx focussed role.
Highlights
- Created and rolled out a suite of 'best practice baked in' copier templates for bootstrapping new service development in the engineering teams. These rapidly became the standard across the organisation and I estimate saved hundreds of engineering hours per year.
- Designed and led the implementation across the organisation of a private PyPI repository in AWS CodeArtifact acting as a cache pull-through, decoupling the estate from public infrastructure, improving the security posture and deployment reliability. Also implemented a preemptive vulnerability scanning process on this CodeArtifact repository.
- Rolled out a fully automated and safe solution for teams to self-provision GitHub repositories using GitHub actions and the templates mentioned above with compliance, security and quality standards managed by automated org-wide rulesets deployed with Terraform.
- Leveraged AFT (Account Factory for Terraform) to create an automatic, standards-compliant system for provisioning new AWS accounts, including a suite of composable customisations to tailor account infrastructure as needed.
- Developed a number of reusable CI/CD pipelines and GitHub actions, standardising common actions across the organisation such as continuous integration in Python repositories, and the Terraform plan, review and apply lifecycle.
- Held workshops and wrote user guides to help upskill the engineering teams in infrastructure and DevOps, particularly debugging in AWS and using Terraform for IaC.
- Led the introduction of infrastructure/deployment testing to the Cloud Platform team, improving the quality and reliability of the shared components we developed.

Tech Lead
Promoted to technical lead of a cross-functional pod; setting a technical & strategic direction, designing higher level architectures, acting as a the organisation's SME for our area, and leading a team of several developers and QAs.
Highlights
- Led a newly created cross-functional team building an entirely new easy access savings product, using a new core banking platform.
- Championed and introduced the use of static typing in python code as well as significantly stricter linting via ruff, leading to a measurable reduction in production errors across a number of core services, and an improved developer experience with faster feedback.
- Led a serverless workshop for developers new to the stack, upskilling them in AWS CloudFormation, SAM, Lambdas, API Gateway, DynamoDB and event driven architecture.
- Participated in the interviewing and recruitment of new engineers up to staff level.
- Mentored new team members and helped to foster an attitude of engineering excellence and best practice within the team and across the engineering department.
