Senior Full-Stack Developer – Flutter + Laravel + MySQL – Booking Platform

Senior Full-Stack Developer Needed – Flutter + Laravel + MySQL We are looking for an experienced Senior Full-Stack Developer to work on a large-scale beauty and service booking platform. This is not a simple website project. The platform will include mobile applications, backend APIs, business and professional accounts, scheduling and booking, payments, notifications, customer management, and other modules. Required technical experience: Flutter Laravel / PHP MySQL REST API development and integration Software architecture Authentication and role/permission systems Git/GitHub Secure and scalable backend development Experience with Stripe Connect, payment platforms, booking/scheduling systems, and marketplace applications is highly preferred. IMPORTANT: This project has existing documentation and business requirements. However, we are establishing a new technical implementation and do not want the developer to simply continue or copy a previous developer’s architecture or codebase. The selected developer must first review the approved requirements and propose a clean, scalable technical architecture before major development begins. We want clear separation between frontend, backend, APIs, database, infrastructure, and business domains. Major architectural decisions must be documented and approved before implementation. First stage: Before assigning the full project, selected candidates may be asked to complete a small paid technical milestone to demonstrate their architecture, code quality, documentation, communication, and ability to follow requirements. When applying, please answer: How many years of professional experience do you have with Flutter and Laravel? Show us 2–3 production applications you personally helped build and explain exactly what you built. Have you built a booking, marketplace, or multi-business SaaS platform? Have you implemented Stripe Connect? How would you structure Flutter, Laravel APIs, MySQL, authentication, roles/permissions, environments, and deployment for a platform expected to grow? Are you comfortable working from approved documentation and obtaining approval before making major architectural changes? Please do not send a generic proposal. We are looking for a senior developer who can explain technical decisions clearly and demonstrate previous work.
