What is
iWork.

A research console for designing and running wellbeing studies: protocols, multilingual quizzes, macro-actions, reports and mood tracking — managed by the researcher and her team with granular roles and REST APIs ready for integration.

02

Where we
started.

A researcher designs wellbeing programs, but distributes them via PDF and email. Quizzes kept in spreadsheets, translations redone by hand for every country, responses collected however they come in. A solid protocol, a process that doesn't scale.

i.

The challenge

Turn a wellbeing research protocol into a multilingual digital product. Three roles — researcher, company manager, employee — with distinct permissions and views. Multiple domains: programs, quizzes, content, organizations. Clinical history tracked without ever losing a data point.

ii.

Our approach

One data model for every domain. JSON translations managed inline by the researcher, no lookup tables. Context-aware scoping: every user sees only what their context authorizes. Weekly demos with the lead researcher, soft-delete everywhere so no state is ever lost.

iii.

The result

Wellbeing programs distributed across multiple countries without going back through manual translation. A research protocol digitized from collection to reporting. The researcher is self-sufficient managing content — no more tickets to change a single question.

The researcher's overview.

You land straight in the console: study KPIs, cohort compliance, recent activity and protocols awaiting publication — all on one screen, no support needed.

Admin console · homeA wellbeing program launched in 10 minutes. It used to take weeks of setup, manual translations and spreadsheets emailed back and forth — now the researcher opens the console and knows where to look in two seconds.

Key
features.

Four main areas of the admin console. Each area is a full CRUD scope, with soft-delete, multilingual content and context-aware user scoping.

i

Quizzes &
answers

Question editor, multilingual answers, scoring and categories. Versioning and controlled publishing.

ii

Study
protocols

Step sequences, macro-actions, dependencies and gating. Items linked to strengths, mood and categories.

iii

Reports
& export

Dashboards for the researcher, CSV/Excel export with custom filters. Aggregations by group, period and category.

iv

Notifications
& mood

Configurable triggers, FAQ, support requests. Mood tracking and reminders to keep participant compliance high.

04

Three roles,
distinct scopes.

Context-aware authorization: each role sees only what it needs. Operators have read-only access to lists — no destructive actions, ever, by mistake.

Domains
managed.

Twelve Prisma aggregates with soft-delete (deletedAt) everywhere, multilingual fields stored as JSON (name, description, title) and user scoping on every REST endpoint.

Technical
features.

Architectural choices built to last: a single source of truth for types, lazy loading on admin routes, per-environment configuration, native multilingual support from day one.

i.Multilingual JSONEvery translatable field (name, description, title) is stored as Prisma JSON. No separate translation table, no cross-language join: the payload is already internationalized at the source.
ii.Soft delete everywhereThe deletedAt field is present on every aggregate. No row is ever physically deleted: history, audit and restores stay possible without a backup dump or restore.
iii.Context-aware user scopingThree roles (ADMIN, USER, Operator) with dedicated NestJS guards. Operators see lists as read-only — the backend filters at the repository level, not the controller.
iv.Lazy loading admin routesEvery Angular feature is a lazy route with selective preload. The initial bundle stays under 280 kB gzipped — the admin console loads fast even on corporate 4G connections.
v.Per-environment config.env.{env} files validated at startup with Zod. Dev, staging and production share the same schema — no deploy surprises, no missing variables discovered at 11pm.
vi.Nx monorepo · shared libraryA single @i-work/lib library exposes types between backend and frontend. When the Prisma schema changes, the TypeScript error shows up before the next deploy — not in production.
