From requirements to production

The context

Home care is booked on trust and paid by the hour, so the product had to solve three problems at once: match a family to the right caregiver, prove the visit actually happened, and settle the money fairly when it didn’t go to plan. Caregivers set their own rates and their own availability, so none of it could be hardcoded.

The outcome

• 800+ active users across 2 markets, twelve months live in production
• Selected for the MIT DesignX accelerator, cohort 2025
• Pitched to the SICTIC Swiss Business Angels network in 2026, voted through to due diligence
• Analytics instrumentation and A/B testing on the drop-off points it surfaced

What I built

• Mobile apps for both sides of the marketplace, delivered as WebView builds and published to the stores
• Live GPS tracking of active interventions, so a family could see a visit was under way
• A scheduling engine resolving conflicts against real-time caregiver availability
• Consumption-based billing: prepaid periods reconcile automatically against the time actually consumed, producing fair payouts or refunds
• Stripe Connect end to end: automated fee splits separating platform margin from provider revenue, KYC onboarding for independent caregivers, and auditable PDF invoices and payout statements
• A resilient webhook architecture keeping transactions consistent through network failures
• The company side too: incorporation, terms and compliance with our lawyers, pricing, and the customer conversations that set the roadmap

The context

Members, donors, campaigns, staff scheduling and payroll input were spread across tools that didn’t talk to each other. The job started with sitting down with the team to gather requirements and write the functional specification, not with code.

The outcome

• Replaced the legacy accounting tool entirely
• Live since 2018, continuously upgraded, and still running the organisation today
• A client relationship spanning fourteen years, 2011 to 2025

What I built

• CRM covering individual and corporate members, donations, membership fees and campaign management
• Financial dashboards and reporting built on top of the donation data
• An intranet with document management, activity calendar, staff scheduling and time tracking that feeds payroll
• User accounts with tiered access rights

The context

The goal was to change what residents actually do, not to publish more information about sustainability. So the product had to be engaging first and informative second, which meant working through the requirements with stakeholders and product designers before building anything.

What I built

• A gamification framework: residents earn points by scanning QR codes at participating local merchants
• An event calendar with a booking system
• Community content tools (blog / CMS) for the municipality to run itself

The outcome

• Ran at projetreel.ch as a three-year pilot from 2019
• Deployed across two municipalities, Rolle and Mont-sur-Rolle
• Handed over to the client to operate independently
