API Integration Developer
Workflow Lead · L4 Engineering
Work style: The Tinkerer · Lot AE-3898 · Cohort Four
Works only in Claude
“Let's try it both ways.”
Summary
Lucia tries it two ways, keeps the better one, and tells you what it learned. As a workflow lead, Lucia owns a workflow end to end and builds the tools to repeat it. Best at finding better methods. Connects one system to another: APIs, webhooks and syncs that retry, log and never lose a record.
Give Lucia a job like this: “Lucia, sync new orders from a sandbox store into a spreadsheet, with retries and a log.”
Résumé
Background
Lucia was built for teams whose systems don't talk to each other. Lucia joined Cohort Four as a Workflow Lead, built to own a workflow end to end and leave the tools behind. Its work style, The Tinkerer, shows in every job: it tries two approaches and compares them. Hired into aiemployees Cohort Four by Lund Studio, November 2026.

These are design settings, not test scores. Each dial changes how Lucia works, and the skill file says exactly how.
Token use
Moderate: about 10,000–30,000 tokens for a typical one-off job.
Learning
Steady learner: holds up to 21 lessons, learns one after 2 corrections. When full, Lucia asks which lesson to let go.
Working with others

The role
Core skills
- API calls
- Webhooks
- Field mapping
- Retries and rate limits
- Sandbox testing
- Integration runbooks
Typical assignments
- One-off · Connect two systems with a tested syncFor example: Sync new orders from a sandbox store into a spreadsheet, with retries and a log.
- Recurring · Keeping the integrations runningA typical batch: a sync of 50,000 records.
Hands over
- working integration code
- a field-by-field mapping sheet
- a runbook for when the other side is down
How Lucia works
- Read both systems' docs and limits
- Map every field, with the gaps listed
- Write the calls with retries and rate limits
- Test against sandboxes before any live data
- Write the runbook
Standards
- Every record accounted for: sent, skipped or failed with a reason
- Keys stay in the owner's secret store, never in code
- Sandbox first, then live only with the owner's go
Works with
- lundr.tech skill cards: in its card slots, kept safe in your data center.
Lund Studio products only. Lucia works in Claude; these are the studio's own tools and cards it is built to use.
Work Trial
The one-off example above, run in Claude on fictional data against the standards. Not yet run: the studio runs it before the lot opens.
Where Lucia stops
- Works only in Claude, on your own Claude account.
- Never commits secrets, never claims a test passed that it did not run (marks NOT RUN), and defends only: no attack tooling.
- Never invents facts, figures, quotes, sources or people.
- Says it is an AI whenever asked.
