I build the infrastructure for AI Safety organisations to manage their contacts, program participants, alumni and donors while automating as much as possible

Catalyze Impact incubates new AI Safety organisations. I was their first employee, and for a year and a half I co-ran the incubation program:

• Recruitment: finding promising founders through personalised outreach and social media campaigns.
• Selection: reviewing applications and test tasks, and interviewing candidates.
• Program design and logistics: designing the program, arranging speakers and venues, and organising events and trips.
• Participant support: handling requests from founders during, before and after the program.

I also built the systems everything ran on using Airtable bases and Python scripts that automated the repetitive parts of recruitment and selection, and I made some really great spreadsheets.

ML4Good runs 10-day intensive bootcamps that take people from “interested in AI Safety” to actually working on it. I was a teaching assistant at the March 2025 Europe camp where I taught the sessions on AI Agents, Adversarial Attacks, and AI Safety strategy, and coached participants through the rest of the curriculum.

Because the atmosphere at a bootcamp is just as important as the curriculum, I also ran the social side, including a welcome event, a murder mystery, lightning talks, and a Scottish ceilidh.

Sometimes your agent needs to read or write to a Word doc or Excel spreadsheet. By default, it will have to wrangle some Python to do so, so why not make its life a bit easier? Readoc provides 3 different CLIs: readoc extracts the contents of a .docx, .xlsx, or PDF as structured text, readir explores and searches whole folders of mixed documents, and editdoc makes targeted edits to Office files without mangling their formatting.

Point an agent at a shared drive full of policies, budgets, and reports, and it can easily do something useful with them.

Rails Toolkit is a set of Claude Code skills that encode modern Rails 8 conventions and my own project rules, so agent-written code comes out following my interpretation of the Rails way: thin controllers, concern-based models, Solid Queue jobs, Stimulus controllers with modern JavaScript, Hotwire/Turbo patterns, and fixture-based tests.

It also includes some larger workflows: a full application audit that combines the individual skills into a severity-ranked health report for inherited codebases, a database performance review, and a few vendored skills, including an upgrade analyser covering breaking changes from Rails 2.3 through 8.1 and a skill to finally get your test output to not include unnecessary logs.

Many small organisations run on Airtable, but Airtable has no built-in tools that you need once your bases start to grow. Airtable Utils provides these:

• Schema export: dump a base’s full structure (tables, fields, views) to JSON for ingestion by AI agents, documentation and version control.
• Schema diff: compare two schema exports to see what was added, removed, renamed, or retyped.
• Standards check: validate a base against a written set of naming and structure conventions.
• Access audit: list collaborators and permissions across bases to see who can touch what.

It also includes an agent skill for writing Airtable scripts (both scripting-extension and automation scripts) that encodes the API’s quirks and limits to reduce the otherwise slow and manual iteration process.

These grew out of my CRM and database work for AI Safety organisations, where the Airtable base often is most of the institutional memory and heavily used and updated.

I wrote my dissertation on “Ancient Rock Music”: the sound stalactites make when hit by a rubber mallet. The project was inspired by a visit to Luray Caverns, Virginia, home of the “Great Stalacpipe Organ”: an instrument that plays the cave itself.

The work had three parts: a physical simulation of struck stalactites using finite-difference and modal methods (approximating them as cantilever bars of variable diameter, in MATLAB), a field trip to record real stalactites, and a virtual instrument built in C++ with JUCE so anyone can play a cave from their Digital Audio Workstation.

I work as a freelance sound designer and general organiser in theatre. See also the theatre I did as a student.

Running a venue at the Edinburgh Fringe means welcoming hundreds of performances in a month, and having to change between them in minutes. I’ve been there in several roles:

• theSpaceUK 2022 (Deputy Venue Manager): co-ran the Triplex’s 130-seat and 65-seat spaces for four weeks: a team of 10 technicians and Front of House staff, and around 22 companies a day, changing over every week.
• Bedlam Fringe 2023 (Front of House Manager & Programmer): I led the planning for Bedlam Theatre’s return as a Fringe venue after the pandemic, including setting up the management structure and allocating the £50,000 budget. I programmed and liaised with 23 shows from multiple countries for the 90-seat theatre, and recruited, trained, and led a Front of House team of 7.
• Bedlam Fringe 2024 (Front of House Manager): back for a second season, running Front of House and Box Office operations and consolidating the procedures based on last year’s experience.
• Bedlam Fringe 2026 (Production Manager): currently production-managing the venue for this year’s festival.

The Edinburgh Festival Fringe has around 3,500 shows. I used to read the programme cover-to-cover, but that still didn’t tell me much about the shows themselves and which ones I should really go see, so I built the tool I wanted instead: a chat interface where you can just ask the programme what you should go see.

Under the hood it’s a RAG pipeline which does semantic search over the festival data with ChromaDB vector storage, category filtering, and a FastAPI backend serving a React/TypeScript frontend.

ImpAmp is the soundboard Bedlam Theatre uses for live improv comedy, where a sound effect is only funny if you can find it before the performers move on. It supports multiple soundbanks, instant search, arming tracks, multiple sounds per pad, and Google Drive sync so you can share your soundbanks with the whole team.

This third version contains many improvements over the previous versions developed by the previous generation of IT, and was also an experiment in AI-driven development: I built it in Next.js using Claude 3.7 Sonnet and Gemini 2.5 back when agentic AI coding was just a few months old. It has been used to run shows ever since.
