Hi there, I reviewed your requirements and this looks like something I can handle well. Building dual booking sites on Supabase and Expo is straightforward with the right approach — I've done similar stacks multiple times. I noticed you need both web and mobile versions working seamlessly together, which means we'll want to nail the backend architecture early. I have a couple of questions about your timeline and specific booking features — let's chat through those details. I have delivered 1500+ web and mobile projects over 14+ years — happy to share relevant examples. Thanks, Hasan

Hi, This is Elias from Miami. I understand that you need two interconnected booking sites leveraging Supabase for the backend and Expo for the frontend. The goal is to create a seamless user experience across both platforms while ensuring robust performance and maintainability. To achieve this, I would start by designing a scalable architecture using Supabase for data management and authentication. I will implement Expo for a smooth, responsive frontend, ensuring both sites share a cohesive design and functionality. This approach will facilitate easy updates and feature enhancements in the future. With over a decade of experience as a senior developer, I specialize in building scalable, maintainable systems. I have successfully delivered projects using similar tech stacks, ensuring they meet both user needs and business goals. Q1: What specific features or functionalities do you envision for the booking sites beyond standard booking capabilities? Q2: Are there any particular integrations or third-party services you plan to incorporate? Q3: How do you anticipate managing user authentication and data security across both sites? Regards.

@Friends4it

Hi , I’ve carefully reviewed your dual Supabase Expo booking sites project, including the required tech stack of Supabase, Expo, GraphQL, and TypeScript/JavaScript, along with Twilio integration for SMS/OTP. Your focus on user account management and core booking flow for the first site, plus reusing this foundation for the second, is clear. With extensive experience in JavaScript, Node.js, React, and GraphQL, I’ll build scalable, well-documented APIs and mobile/web frontends that integrate seamlessly. I’ll ensure robust Supabase schema and auth rules, deploy clean code to your Supabase/Vercel environments, and implement Twilio for secure SMS verification. Let’s arrange a meeting to finalize milestones and clarify details. What specific booking features or customization do you envision for the second site beyond the shared foundation? Thanks, Muhammad

As a driven and versatile freelancer, my background encompasses all the key technologies you've outlined for this Full-Stack Developer role. Having extensively worked with Supabase, GraphQL, TypeScript and Expo - I am at home tackling complex systems like yours. I cater to developing your Service Provider platform, Admin & Staff platform while seamlessly integrating them with the existing customer mobile application to ensure an unified experience. My proficiency in designing secure authentication and authorization systems, coupled with experience in implementing Twilio SMS verification uniquely positions me to deliver a scalable and secure system as per your project scope. As well as this, I have a demonstrated ability not only to develop, but document what is developed. Your Deliverables request looks to highlight a beneficiary request as I am adept at designing PRDs, TRDs ,providing detailed technical documentation as my stack especially excels me at documentation. Beyond just understanding and applying technology, I'm focused on delivering more than just code. My goal is always to create something that not only meets technical specifications but also aligns with your end goal and brand values. With my bid estimate on MVP completion being 4 months approximately from beginning of the kick-off meeting.

@AhteshamAK

Hello, I appreciate the clear structure of your project. I can build both Supabase‑powered booking platforms using a shared foundation in TypeScript, GraphQL, and Expo, ensuring consistency, speed, and clean architecture. I will set up scalable Supabase schemas, secure auth policies, and a documented GraphQL API to support bookings, user profiles, and future expansion. The web front end will cleanly connect to the API, and Twilio will be integrated for OTP and notifications. Code will be fully versioned and deploy‑ready for Supabase and Vercel. Best regards, Ahtesham.

@Hammadhassan21

Hi, I’m a full-stack developer specializing in TypeScript and JavaScript, with experience building modern web and mobile applications using Supabase, Expo, GraphQL, and React/Next.js. I’ve delivered production-ready apps with authentication, booking flows, and third-party integrations like Twilio for SMS and OTP verification. I understand that you need two related platforms built on a shared modern stack: the first a service booking site with secure user accounts and a smooth booking flow, and the second leveraging much of the same foundation for future feature expansion. Both need clean, maintainable code, fully documented APIs, and a consistent mobile and web experience. I can set up your Supabase backend with schema, auth, and storage rules, build a GraphQL API with queries, mutations, and subscriptions, create the Expo mobile shell consuming the API, develop the web front end in TypeScript, integrate Twilio for SMS, and ensure everything is well-documented and deployable. My approach is to structure the code for reusability, implement the core flows first, and maintain clear documentation to streamline future updates. I’m available to start immediately and can dedicate the time needed to build both platforms efficiently. I’d be happy to discuss your requirements, timelines, and milestones to get started. Let's have a quick chat to discuss your project in detail then we will move forward. Thanks.
