Reseller SaaS & Mobile App Development

@softsolution2000

Hi, the Lovable Cloud migration is the part I'd flag first — moving Postgres/Auth/Storage plus RLS policies to a directly-managed Supabase project without breaking eBay OAuth callbacks or extension endpoints is doable as a config migration, not a rewrite, if the schema's clean. Rebasing three stale branches against ~20 merged PRs is the other real chunk of work before Telnyx SMS or the 1099-K report can even land. We've built RN/Expo apps sharing logic with existing web codebases and handled backend platform migrations without data loss for past clients. Happy to scope Phase 1-3 separately once we talk specifics, though the posted budget looks off for this scope, worth clarifying before anyone bids seriously.

Hi As a seasoned veteran in full-stack web and mobile development, I'm well-positioned to execute all three phases of your project perfectly. My expansive expertise with React.js, TypeScript, and TanStack Start/Router makes me adept at handling complex backend processes and the associated migration tasks. Particularly crucial for phase Telnyx SMS notifications — webhooks, SMS APIs are my stronghold and I specialize in leveraging them to optimize user experience. Moreover, my substantial know-how in Supabase ensures fluid transition during Phase 2. I've successfully executed similar back-end migrations in the past without any data loss, and this experience will lend immense value to your project. To guarantee long-term security, I'll document the entire deployment process meticulously. Lastly, React Native along with Redux-saga & Hooks is another of my strong suits making me an ideal choice for your companion mobile app development. Thanks....

Hello There!!! ★★★★ ( Full Stack SaaS + React Native Expansion for FlipIQ Platform ) ★★★★ Project understanding: You need a senior React/TypeScript developer to complete backend features, stabilize and migrate your Supabase backend off Lovable Cloud, and build a companion React Native (Expo) mobile app. The work includes fixing API logic, SMS integration, database migration, and creating a scalable mobile dashboard for inventory and notifications. Services offered: ⚜ Backend completion in React + TypeScript with Supabase (Postgres, RLS) ⚜ Fixing & rebasing existing feature branches with conflict resolution ⚜ eBay API automation + cross-listing workflow corrections ⚜ Telnyx SMS integration with opt-in/out and webhook handling ⚜ Full Supabase migration (schema, auth, storage, environment setup) ⚜ React Native (Expo) mobile app for KPIs, inventory & alerts ⚜ Scalable architecture for multi-tenant SaaS + future expansion I’ve worked on SaaS platforms with Supabase backends, API-heavy workflows, and React dashboards where stability and clean data flow were critical. My approach is phased: first stabilize backend + merge branches, then handle migration safely with zero data loss, and finally build a clean mobile layer on top of the existing system. Let’s connect and I’ll break down each phase with clear timelines so we can move fast without breaking production. Warm Regards, Farhin B.

@johnallenvillan1

Hi there, Your FlipIQ stack needs three things handled cleanly: the stalled backend branches, the Lovable Cloud dependency, and the Expo app. I’ve spent the last 4 years solving exactly this type of problem. I’ve rebased large React/TypeScript codebases with conflicting feature branches, migrated Supabase-backed products to managed infrastructure, and shipped React Native apps that reused shared business logic without duplicating the core engine. The real risk here is not the features themselves, it’s preserving tenant isolation, RLS behavior, auth callbacks, and marketplace automation while moving fast. A junior dev usually breaks redirects, storage references, or branch history during a migration like this. I will rebase the three open branches against main, merge the stale job reclaim, 1099-K reporting, eBay auto-delist, and Telnyx SMS flows, then move the backend to a directly managed Supabase setup with validated env vars, redirect URLs, and storage paths. After that I’ll build the Expo app around shared types and calculation logic, focused on dashboards, quick-add with camera capture, pricing, ledger, and push alerts. Best regards, John allen.

@FizzaNadeemK

A system like FlipIQ only becomes stable when the backend stops being split across experimental branches and starts behaving like one controlled engine with clear data ownership and migration safety. Phase 1 is where most of the real risk sits—rebasing old feature branches, fixing queue-based delist logic across marketplaces like eBay, and making SMS and job systems behave predictably under load instead of conflicting after merge. Phase 2 is not a rewrite but a controlled relocation of your Supabase setup so auth, storage, RLS, and API endpoints continue working without breaking OAuth flows or extension callbacks during migration. Phase 3 in React Native + Expo is best kept lightweight: dashboards, inventory capture, and alerts only, while the Chrome extension continues handling marketplace automation so responsibilities stay cleanly separated. What matters most first: are the current branch conflicts blocking production use, or is the system already live and just partially unstable? Best regards, Fizza Nadeem K

@fullstack0407

I have read your job post and I am a Full Stack Developer with experience in React, TypeScript, React Native (Expo), Supabase, PostgreSQL, Chrome Extensions (Manifest V3), and SaaS application development. I have worked on large production applications involving Supabase migrations, RLS policies, REST APIs, authentication, and mobile applications sharing logic with existing web platforms. I am comfortable taking over established codebases, resolving complex Git conflicts, rebasing long-lived branches, and delivering production-ready features without disrupting existing functionality. Before providing a detailed estimate for each phase, could you share: 1. Approximately how many active users and records are currently in the Supabase database? 2. Is the AI valuation service already implemented as an API, or will that integration also be part of this engagement?
