Full-Stack Developer (Remote, Contract)

About the Role

We at JVDB Studios are looking for a Full-Stack Developer to lead the end-to-end development of a mobile-first workforce management platform. This is a hands-on role where you will own the full technical build—from architecture to deployment.

You’ll be working on a product designed to replace multiple operational tools (scheduling, HR, quality control, invoicing) with a single integrated platform, with future plans to scale into a white-label SaaS solution.

This is a high-impact opportunity to build a product from the ground up with a direct European company, offering strong compensation and flexible working conditions.

What You’ll Build

The platform will be developed across three phases:

Phase 1 – App v1.0
User profiles and onboarding system
GPS-based check-in (geofencing)
AI chatbot assistant (RAG-based knowledge system)
Data ingestion pipelines (internal + public sources)
Internal testing and iteration

Phase 2 – Operational Platform
Scheduling API integrations
Gamification system (levels, badges, rewards)
Internal shift marketplace
AI-powered photo quality scoring (computer vision)
Expanded AI assistant capabilities

Phase 3 – Market-Ready Product
Automated scheduling and planning engine
Full HR module (contracts, hours, leave tracking)
Automated invoicing system
AI-driven performance insights
Multi-tenant architecture for white-label deployment

Technical Requirements

Mobile Development
React Native or Flutter (single codebase for iOS & Android)
Experience with device APIs (GPS, camera, push notifications)

Backend
Node.js (Express/NestJS) or Python (FastAPI/Django)
RESTful APIs and real-time systems (WebSockets/SSE)

Database
PostgreSQL (preferred)
Experience with scalable schema design (SaaS, multi-tenant systems)

AI / ML Integration
Experience with RAG pipelines (vector databases + LLM APIs)
Computer vision integrations (or third-party APIs)
Strong prompt engineering skills

DevOps
Docker, CI/CD pipelines
Cloud platforms (AWS, GCP, or Azure)

Security
Role-based access control
OAuth2 / JWT authentication
GDPR-aware data handling

Nice-to-Have
Experience building white-label SaaS platforms
Background in workforce management / scheduling systems
Gamification systems (XP, leaderboards, rewards)
Geofencing/location-based applications

Candidate Profile
Strong portfolio with at least 2 live mobile applications
Proven experience integrating AI into real products
Ability to work independently and make technical decisions
Clean, scalable coding practices
Responsive and proactive communicator

Engagement Details
Type: Freelance / Contractor
Duration: 18–24 weeks (with potential extension)
Hours: 30–40 hours per week
Rate: USD TBD
Timezone: Minimum 4-hour overlap with CET (Amsterdam time)
