an AI-assisted care platform and printable-activity engine
What if care teams could create personalised activities for older adults from one platform?
A production Next.js platform for older-adult care: personalised printable activities (CarePrints), family engagement tools, e-books and memoir workflows, subscriptions and admin operations. Over fourteen months I worked mostly on the activity engine — the generators, editors and export pipelines behind the product’s core.
RoleFull-stack developer / software engineer
My partTeam of four engineers · ~300 of my commits since July 2025
Built activity generators for the printable-activity engine — rectangular, circular (with inner holes and a centre start) and triangular mazes, riddles with smart font sizing, word grids, picture memory cards, nostalgic photo cards, memory-lane trivia and Words of Comfort — each with customisation sidebars, SVG preview and PDF/PNG export.
Built the Stories2Connect canvas editor with dual-version export and answer toggles, and the backend PDF generation pipeline used across activity types.
Prototyped the AI e-book generator with user/AI segment control, and shipped AI-assisted generation with OpenAI and Google Gemini for activities, images and structured content.
Extended Family Circles with member-specific prompts, quick actions and admin views of member answers; added bulk CarePrint assignment by tag and the admin navigation for the CarePrints and Care Pals super-sections.
Worked across the platform’s integrations — NextAuth.js role-based access, Stripe subscriptions, Resend/React Email campaigns, Twilio phone verification, S3-compatible storage — and fixed production incidents in download quotas, export pipelines, email broadcast analytics and deployment.
Helped split the codebase into CarePrints and LiveAndStay, repointing shared word-grid code to published packages behind strangler facades, and added Prettier/Husky gates and CI memory fixes.

The activity engine
Every printable activity is a small program: typed parameters, a generator that produces content, an SVG renderer for the live preview, and an export path to PDF and PNG. The mazes are a good example — rectangular, circular and triangular variants share one grid abstraction but need their own carving and rendering logic (a circular maze with a hole in the middle has a different notion of “neighbour” than a rectangle). Riddles size their type to fit the page. Stories2Connect adds a canvas editor on top so a carer can adjust a story before it prints.
In 2026 the engine was extracted into published packages (@teamanaya/activity-core, activity-renderers) so CarePrints, LiveAndStay and Anaya Care could share it. My part was repointing the word-grid code behind strangler facades so the split shipped without a flag day.
