Twilio Developer for Child Safety Alert

Twilio Developer Needed — Child Safety Alert System (MVP Build) OVERVIEW I am building SafeArrive, a child arrival safety alert system for schools, preschools, daycares, and summer day camps. When a child does not arrive by a set cutoff time, the system automatically contacts parents by text, then phone call, then escalates to emergency contacts and school admin. This is a child safety product. Reliability and clean code are non-negotiable. A full product specification document is attached. Please read it completely before submitting a proposal. WHAT NEEDS TO BE BUILT A web-based platform with three user types: school admin, teacher, and parent. No native app required. Everything runs in a browser. Core features include: - Parent self-registration via unique link with child info and emergency contacts - Teacher attendance marking via mobile browser each morning - Automated Twilio SMS alerts when a child does not arrive - Automated Twilio voice calls with keypad menu if no text response - Multi-step escalation to emergency contacts and school admin - Admin dashboard with real-time alert status - Daily morning and end of day summaries sent to multiple recipients - Configurable school calendar with recurring observance day and holiday blocking - Configurable cutoff times per group with full time zone and daylight saving time support - Support for call-only phones with no SMS capability - Full immutable audit log of all system events - System self-check every morning before school day begins Full feature list is in the attached spec document. TECH REQUIREMENTS - Twilio for all SMS and voice - Web-based, mobile-responsive, browser only - Secure unique links for parents, no app required - Standard email and password login for admin and teachers - Must handle multiple schools simultaneously Stack is open to your recommendation. Please state what you propose and why. TIMELINE MVP complete by mid-August 2026. This is a firm deadline tied to the school year start. BUDGET 8,000 to 10,000 dollars fixed price. If you believe the scope justifies a higher number, provide a detailed feature-by-feature breakdown explaining why. Proposals without a breakdown will not be considered regardless of price. ONGOING WORK After launch I expect the developer to be available for maintenance and bug fixes at an agreed monthly retainer. If you are not open to ongoing work after launch, please do not apply. TO APPLY Tell me briefly about a similar project you have built. Attach your proposal with a feature-by-feature cost breakdown. Developers who clearly read the spec will be prioritized.
