Brief intro

Hi! I'm Danny. I am an excessively enthusiastic software developer.

Work

I'm currently a Lead Developer at HMCTS, working in the Developer Enablement team. I previously worked as a Senior Developer within Employment Tribunals and as a Software Developer in the Court and Tribunal Hearing Service team.

In addition to full-stack work on the above, I've also been involved in the following:

• Cloud cost reductions resulting in at least £50k in annual savings
• Presenting to cross-organisation engineering teams on speeding up jest test suites and Yarn v3 migrations
• Presenting on effective use of large language models (LLMs) both at the organisation level and to cross-disciplinary teams
• Building new features for HMCTS' master CI/CD pipeline
• Leading culture change efforts to empower developers and reduce barriers to innovation
• Discovering and highlighting security vulnerabilities in our applications
• Organising and giving talks at developer town halls
• K8s cluster performance improvements

Projects

Outside work, I've developed a few apps, including:

• An exemplar serverless function linking custom KQL queries in Azure LogAnalytics with Slack
• E2EE secure messaging Android app using a combination of client-side asymmetric (Elliptic Curve Diffie-Hellman) and symmetric(AES-256) encryption approaches, WebSockets. Kotlin for client-side, Python server-side.
• Rust-based CLI for interfacing with OpenAI models such as GPT-4.

I discovered (alongside Tim Jacomb) a few CVEs in Jenkins:
CVE-2023-30513, CVE-2023-30514, CVE-2023-30515

Technical interests

• AI/ML Security
• Serverless functions
• Functional Programming
• Data Engineering
• Using Azure's Kusto Query Language (KQL) in non-standard ways
• Culture change

General

• I have been running a reasonably successful Mandarin Language group in Glasgow since 2018.
• I write world-class complaint letters.
