How I work

Build useful things

I turn a specific problem into working software, using AI-assisted development and refining the controls, feedback and workflow around the person using it.

Make the story clear

I bring together video, sound, motion graphics and live production to take a story from an initial idea to a finished piece for its audience.

Help others create

I develop programmes, studios and practical training that help people build confidence and create work for a real audience.

Portfolio

Useful software.
Powerful storytelling.

I build digital tools, produce media and lead creative programmes. Explore the work—and the decisions, people and results behind it.

Software & AI in practice

Tools used daily across Berkley classrooms and in TV production. Built with AI assistance; AI-powered features are identified in each project.

Illustrated attendance workflow from absence email to checked eTap update and staff handover

In use · operational automation

Attendance workflow automation

I proposed, built and maintain a Gmail-to-eTap workflow that handles routine absence entries and flags exceptions for staff.

The attendance officer reports saving over an hour per school day, closer to two. Rules-based operation, built with AI assistance.

YumDonut’s shared team goal showing progress towards 1,000 donuts and contribution controls

Two years in use · Web + Microsoft Teams

YumDonut

A recognition system built for my classroom team of 20+: celebrate contributions and shared values, then put earned donuts towards team goals.

My work & project notes

I built YumDonut to meet our recognition needs without subscribing to a service such as HeyTaco. The standalone app and Teams integration share recognition records, balances and activity.

My students and I have used YumDonut for two years. Both the web app and Teams integration are now in use; that history refers to the product overall. The app link opens participant sign-in.

Prompter’s script view, reading guide and rehearsal controls

Working browser demo

Prompter

A teleprompter built around the presenter’s delivery, with voice following, a demo reader and mirrored display for presentations, training and video production.

My work & project notes

I developed the app and refined its reading behaviour: keeping the eyeline steady, preserving punctuation and allowing manual repositioning without fighting the scroll.

Voice following uses Speechmatics speech recognition and requires microphone access and a service connection. The browser demo runs without a microphone. Voice performance depends on the device and connection.

Classroom dashboard with sample lesson instructions, a clock, a five-minute timer and a group-work cue

One year in use · Teacher dashboard

ClassroomScreen

One screen for everyday classroom routines: arrange instructions, timers and working-mode cues, then save the layout for another lesson. Used by me and other teachers for a year.

My work & project notes

I built this dashboard to meet our classroom needs without a paid subscription. It is my independent project, inspired by the commercial Classroomscreen product.

I brought movable tools, saved layouts and scheduled switching into a shared workspace. Layouts are stored in the browser, with export/import for moving them between devices.

The screenshot shows a sample lesson in the live app. My colleagues and I have used the project for a year, as of September 2026.

SketchMotion drawing workspace with a circle, tools and frame timeline

Working browser app

SketchMotion

A drawing and animation workspace for turning a rough idea into movement: sketch, build frames and play the sequence back.

Related tool: Maze Flow — Wacom pen practice for my students’ 2D animation project.

My work & Maze Flow

I developed the drawing and animation workflow, with a shared background and a separate drawing layer for each frame. Recent refinements clarify those layers and use project names for exports.

Projects autosave in the browser and can be saved as files. Export options include images, GIF and WebM. Longer animations can take time to export; browser storage is not a substitute for saving a copy.

Maze Flow: practice before production. I built this game so students can practise guiding a Wacom pen through a maze during our 2D animation project. Immediate feedback when the path touches a wall turns pen control into a focused, playful exercise.

SketchForge Learn screen showing the guided basics tutorial added in Carl’s version

Ongoing development · derived project

SketchForge 3D

Extending a browser 3D editor with guided learning, project handling and interaction refinements that make modelling more approachable.

Original application by Formsmith746. My version extends that work.

My improvements & original credit

The original project supplies the core 3D workspace, shapes, solid/hole modelling and model import/export. My additions include guided tutorials, project save/open, printable starter parts and refinements to placement, rotation and camera controls.

My branch derives from an MIT-licensed version. The upstream project has since changed licence. See the licence for my version and the original base licence. Screenshot credit and licence: SketchForge contributors. This remains a work in progress.

Just the Good News website with featured story, topic filters and source links

Live website

Just the Good News

An AI-assisted publishing workflow that gathers positive reporting into a readable website, with topic browsing, search and links to original sources.

My work & project notes

I built the site around a simple idea: make constructive stories easier to find while keeping their sources visible. The live site includes a Kids section and identifies its content as AI-curated and AI-summarised.

The site gathers stories from RSS feeds and uses AI to select and summarise them, keeping links to the original reporting. Automated updates build the site and publish it through GitHub Pages.

Image Optimizer Studio showing compression presets, output formats and the image upload workspace

Live web app · also runs locally

Image Optimizer Studio

A focused workflow for preparing web images: batch compression, resizing and format conversion, with before-and-after file information and a local processing option.

My work & project notes

I built the interface and local processing workflow around existing image codecs. The design brings compression presets, output choices and per-file savings into one place. It needs a local server or a compatible host; this is not a browser-only compressor.

Try the hosted app, or run it locally to process images on your own machine. The hosted version processes uploaded images on its server and may take a moment to wake up. Compression results depend on the source image and settings.

Creative communications & student media

Berkley school website desktop view with full navigation, campus aerial image and family links

My design, development & production

Berkley: website & prospectus

I proposed bringing the work in-house, then delivered website design and rebuilt pages, a campus map with 360° views, zone and bus finders, and a prospectus I wrote, photographed and designed.

Savings helped fund a new camera. I continue to develop the website and tools; the supplier built the underlying backend.

Watch A Day in My Life at Berkley Normal Middle School, by Berkley TV

Programme founder & mentor

Student voices, real productions

I established ESTV, SFTV and Berkley TV. I lead the programme, training and production standards; students take the creative lead. At Berkley, that includes four-camera live broadcasts. At SJI International, the school’s YouTube channel grew from 200 to 1,600 subscribers during my 2016–2022 tenure.

Featured: A Day in My Life at Berkley Normal Middle School. Students create the work, with my teaching and production guidance. At Berkley TV, subscribers have grown from 200 to 1,410 during my leadership (September 2026).
