Download the working MVP (FastAPI + SQLite, bilingual UI)

Here’s a fully functional prototype you can run locally:

Download Trabajar Demo MVP (ZIP)

What this MVP already does

  • ✅ Customer + Worker roles
  • ✅ Post jobs → workers apply → customer selects
  • ✅ Check-in / check-out flow
  • ✅ Customer confirms completion
  • ✅ Bilingual UI (English / Español) toggle
  • ✅ “Escrow + payout” flow as a demo ledger (no real payments yet)
  • ✅ Job chat (unlocks after assignment)

Run it locally (3 commands and you’re live)

Unzip, then from the project folder:

python -m venv .venv

source .venv/bin/activate   # Windows: .venv\Scripts\activate

pip install -r requirements.txt

uvicorn app.main:app –reload

Open:

  • http://127.0.0.1:8000

Quick demo loop (feels like the core product)

  1. Sign up as Customer
  2. Post a job
  3. Open a second browser/incognito → sign up as Worker
  4. Worker applies
  5. Customer selects worker
  6. Worker check-in → check-out
  7. Customer confirms completion
  8. Watch the Payments (demo ledger) entries update

Now the real “Build Trabajar” plan (production-grade)

You already have the core marketplace loop. Here’s how to turn it into a legit, scalable platform without getting crushed by payments, fraud, or compliance.

1) Production architecture (clean, scalable, fast)

Client apps

  • Mobile-first: React Native (Expo) or Flutter
  • Offline-resilient job viewing + quick apply
  • Push notifications (job offers, selection, reminders)
  • Built-in bilingual UI + chat translation

Backend services (modular, not a monolith blob)

  • Auth + Identity (users, roles, verification)
  • Jobs (posting, details, rules, templates)
  • Matching (availability + proximity + reliability score)
  • Payments (escrow, payouts, refunds, fees)
  • Messaging (chat + translation + moderation hooks)
  • Trust & Safety (risk scoring, bans, incident reporting)
  • Admin Ops (disputes, identity review, refunds, compliance flags)

Data stack

  • Postgres (primary)
  • Redis (queues, rate limits, matchmaking)
  • Object storage (job photos, IDs, certifications)

2) The money engine (how Trabajar prevents wage theft)

Non-negotiable: customers fund the job upfront.

Flow

  1. Customer posts job → pays into escrow
  2. Worker completes → customer confirms (or auto-confirm after a window)
  3. Instant payout to worker
  4. Platform fee comes from customer side (not worker)

What the product MUST show clearly

  • Worker sees guaranteed pay before accepting
  • Customer sees total cost (labor + fee) before posting
  • Cancellation rules and fees are visible upfront

(In the demo, this is simulated via the “ledger.” In production, you wire this to real payments.)

3) Matching logic (simple first, deadly effective)

Start with a score that’s explainable and fair:

MatchScore =

  • Distance / ETA
  • Worker availability now vs scheduled
  • Skill tags overlap
  • Reliability (no-show rate, completion rate)
  • Customer rating protection (block repeat bad customers)
  • “Repeat hire” preference (favorites boosted)

You don’t need “AI magic” to win early. You need fast fills + low drama.

4) Trust & safety: make it the brand

Customer verification (reduces scams)

  • Identity verification + valid payment method
  • Address confirmation
  • “Job site reputation” (ratings + incident reports)

Worker protection (this is the moat)

  • Panic/SOS + share trip/job info
  • Buddy mode (book 2 workers together)
  • No cash bait-and-switch: pay must be in-app
  • Dispute system with photo + time logs

5) Bilingual UX that actually slaps

This is where Trabajar wins.

UI bilingual

  • Every screen native ES/EN
  • Language stored per user but toggle anytime

Communication bilingual

  • Chat with:
    • auto-translation text
    • voice notes (optional)
    • job templates with icons + photos to reduce misunderstanding

6) MVP → V1 feature unlocks (in the order that matters)

Marketplace fundamentals

  • Push notifications
  • Favorites + rehire
  • Worker availability calendar
  • Job templates by category

Payments + ops

  • Real escrow + payouts
  • Refund logic + cancellation fees
  • Dispute tooling (admin dashboard)

Growth loops

  • Worker referral bonuses
  • Contractor subscription plans
  • “Bench” feature for contractors (trusted worker pool)

7) Compliance reality (handle it like a pro)

You’re building labor infrastructure — which means:

  • Worker classification varies by jurisdiction
  • Taxes, insurance, and local rules matter
  • Don’t build features that encourage illegal hiring or unsafe work

Two clean paths:

  1. Independent contractor marketplace model (requires careful compliance)
  2. Staffing/EOR partner model (you can become “the front-end” for a compliant labor engine)

What you have right now

✅ A working bilingual marketplace prototype you can run today

✅ A production blueprint that covers payments, matching, safety, and scale

If you want the next step to be mobile apps (iOS/Android) + real payments + admin dashboard, tell me your preferred stack:

  • React Native + Postgres (classic, fast hiring)
  • Flutter + Postgres (slick UI, strong performance)

Either way: we can turn Trabajar into a real city-by-city rocket.
