Full-Stack Integration Expert: Multi-Platform OAuth & Automated Analytics Sync (Supabase)

@mascotindia123

Hi, I can build a secure, production-ready integration layer for Insytli that connects Facebook, Instagram, TikTok, and YouTube using official OAuth 2.0 flows and server-side handling in Node.js (TypeScript) with Supabase as the backend. I will design a normalized PostgreSQL schema in Supabase to unify account-level and post-level analytics across all platforms, with proper RLS policies to ensure strict user-level data isolation and security. The system will include encrypted token storage, secure refresh logic, and a 24-hour cron-based sync service with retry handling (exponential backoff) to manage API limits and downtime gracefully. I will also implement a 90-day historical backfill process on initial connection to populate full analytics history for each creator account. All sync operations will be logged in a dedicated audit table, including success/failure states, timestamps, and API responses for full traceability. The backend will be modular, fully testable, and documented, including setup instructions, unit tests, and deployment guidelines for Supabase + Node.js environment. I have experience working with Meta Graph API and understand App Review requirements, including business verification, permissions scoping, and ensuring compliance by requesting only essential permissions, properly documenting use cases, and maintaining consistent API behavior during review and production transitions. Warm regards, Harpreet Singh

Hi, I've built similar multi-platform OAuth integration systems with Node.js/TypeScript and Supabase, so I understand exactly what Insytli needs — secure token management, normalized cross-platform analytics, and reliable automated syncing. My approach: I'll implement each platform's OAuth 2.0 flow with server-side token encryption and refresh logic stored in Supabase, design a unified PostgreSQL schema with RLS policies to consolidate metrics from Meta, TikTok, and YouTube, and build the 90-day historical backfill pipeline alongside cron-based daily syncs with exponential backoff for rate-limit resilience. I've handled the quirks of Graph API pagination and TikTok's sandbox-to-production approval process firsthand. I can start immediately — let's discuss your current progress and get this moving.

Hi there, I can build the full backend integration for Insytli with a secure, production-grade architecture using Node.js (TypeScript) and Supabase as your database layer. I’ve worked on OAuth-based integrations and API-driven systems before, so I understand the complexity of handling Meta, TikTok, and YouTube APIs together—especially when it comes to token security, refresh flows, and rate-limited data syncing. I’d design a normalized PostgreSQL schema in Supabase with RLS policies, encrypted token storage, and a clean ingestion pipeline for both account-level and post-level metrics. For the sync system, I’ll implement a reliable 90-day backfill process plus scheduled cron jobs with retry logic and logging so you always have visibility into success/failure states. Everything will be structured for scalability so you can easily add more platforms later without rewriting core logic. I also ensure full compliance with platform policies, including proper OAuth scopes and Meta App Review requirements for moving from development to production. Looking forward for your positive response in the chatbox. Best Regards, Arbaz M

Hi, This is a solid, well-defined system—and I can build this as a secure, production-ready integration layer that’s scalable and compliant with platform requirements. Why I’m a strong fit • OAuth + API integration experience I’ve implemented OAuth 2.0 flows and long-lived token systems for platforms like Meta and Google APIs, including secure refresh handling and server-side storage. If you’re building this as a long-term product (which it clearly is), I’ll structure the system so it’s ready for future features like analytics dashboards, alerts, or AI insights. Ready to start immediately. Best regards, ADEEL

@raheel2k29

Hello, This is a solid architecture problem not just API integration and I can help you build a secure, production-ready OAuth + analytics sync system for Insytli using Node.js, TypeScript, and Supabase. I’ve worked on similar integrations where token handling, API limits, and data normalization are the real challenges not just connecting endpoints. Why Me This project isn’t just about connecting APIs,it’s about building a secure, reliable data pipeline that won’t break under real-world conditions like rate limits, token expiry, and platform restrictions. That’s where I bring value. I understand OAuth deeply not just basic login flows I build integrations with API limits, failures, and retries in mind, so your system keeps working consistently I design clean, normalized database schemas that make multi-platform analytics easy to query and scale I focus on security-first backend architecture I structure systems so they’re maintainable and extendable If you’re looking for someone who understands real API constraints, secure token handling, and scalable data pipelines, I can build this the right way from the start. Best regards RAHEEL

@arslanshahid386

Hi there, I see you're looking to create a strong backend integration for your creator-management platform, Insytli, focusing on secure OAuth for multiple social media platforms and automated analytics syncing. With 4+ years of experience in Node.js, TypeScript, and Supabase, I can help implement a secure OAuth 2.0 system that encrypts access tokens and manages token refresh logic effectively. I'll ensure that the data ingestion process captures both account and media-level metrics, along with a robust scheduled sync that respects API rate limits. Additionally, I'll design a normalized database schema to keep everything organized and secure. One question I have is about your specific needs for the historical data backfill—are there any particular metrics or insights you want prioritized during that process? Best regards, Arslan Shahid

@chandibraheem58

Hi, multi-platform integrations usually break at OAuth, inconsistent metrics, or failed sync jobs leading to unreliable data. I’ve built Node.js/TypeScript backends integrating Meta, TikTok, and YouTube with secure OAuth and Supabase. I’ll implement encrypted token handling with refresh logic, a normalized schema for unified metrics, and ingestion with 90-day backfill + daily cron sync (with retry/backoff). Sync logs and RLS will ensure reliability and data security. Clean code, tests, and docs included. Meta App Review: request minimal scopes, provide clear use-case flows, handle data deletion, and align with Business Verification to pass smoothly. Timeline: 2–3 weeks. Do you already have API apps approved, or should I handle setup as well? Chand

Hi there! You are building a creator analytics backend across multiple social platforms and the real challenge is not just connecting APIs, but designing a unified, scalable ingestion system that handles OAuth security, rate limits, historical backfills, and normalized metrics across very different data models. On a recent multi-platform integration project, I built a secure OAuth-based data pipeline that synced social performance metrics daily, handled token refresh automatically, and stored normalized analytics in a structured database with reliable retry and logging mechanisms. I will implement a secure server-side system in Node.js with strict TypeScript structure, integrating Meta Graph API, TikTok, and YouTube Data API v3, and storing encrypted tokens and normalized analytics in Supabase using PostgreSQL with proper RLS policies. I will also implement 90-day backfill, cron-based syncing, and a robust logging system for all sync operations. Check our work: https://www.freelancer.com/u/ayesha86664 For your schema design, do you prefer a fully unified “platform-agnostic metrics table,” or a hybrid approach with shared core tables plus platform-specific extensions? I am ready to start - just say the word. Best Regards, Ayesha

@TheDeveloper10

Hi You are looking for a backend developer to build secure, production-ready integrations for Meta, TikTok, and YouTube with robust data syncing into Supabase. Here is my plan I will design a secure Node.js (TypeScript) backend implementing OAuth 2.0 flows for all platforms, with encrypted token storage and automated refresh handling. I’ll build a normalized PostgreSQL schema in Supabase with RLS for strict data isolation, then implement scalable ingestion pipelines for account-level and media-level metrics. A 90-day historical backfill will run on first connection, followed by scheduled cron jobs with retry logic (exponential backoff). I’ll also include structured logging, unit tests, and full documentation for deployment and maintenance. To proceed kindly let me know the following Do you already have developer apps created for all platforms with required permissions approved? What is your expected data sync frequency beyond the 24h cron (if near real-time is needed)? Do you have a preferred queue system (e.g., BullMQ) for handling retries and background jobs? I do have more than 7 years of experience and would be glad to help you in building secure API integrations and scalable backend systems. I am available to discuss—let’s connect and bring Insytli to production readiness. Thank you

⚡ I'm ready to start! ⚡ I work with Node.js/TypeScript and Supabase building secure OAuth and analytics pipelines. Your system needs safe login for Meta, TikTok, and YouTube, plus automated daily syncing of creator metrics into a clean database. I’d build server-side OAuth with encrypted token storage in Supabase, then a cron-based sync service with retries and a 90-day backfill on first connect. Data would be normalized into shared tables with RLS so each user only sees their own stats, plus logging for every sync run. The build would go step by step: OAuth → backfill → daily sync → testing + docs. I would be glad to work with you on this project. Thanks.

@Hrolgar

To answer your bonus question first: Meta Business Verification requires a registered business entity, verified domain, and privacy policy URL. For App Review, I submit each permission with a screencast showing exactly how the data is used, keep the requested scopes minimal, and include a data deletion callback endpoint. The key to staying compliant is only requesting permissions you actively use and responding to Meta's annual re-verification prompts. For the build itself: Architecture: Node.js/TypeScript backend with per-platform modules. Each module handles its own OAuth flow, token refresh, and API-specific pagination. OAuth: Server-side only. Tokens encrypted with AES-256 in Supabase, refresh logic runs before every API call to avoid expired token failures. Data ingestion: - Account-level: followers, reach, impressions, profile views per platform - Post-level: individual media stats (likes, comments, shares, saves, views, engagement rate) - 90-day backfill on first connect, paginating through historical data respecting rate limits Normalized schema: unified metrics tables with a platform column so the frontend queries one structure regardless of source. RLS policies scoped per creator. Cron: 24h sync with exponential backoff retry (3 attempts, 30s/120s/480s). Success/failure logged to sync_logs table with error details. Delivered via Git with unit tests and setup docs. Which platforms are highest priority for your launch?

@cindyviorinar

Hi Client, I’ve read your spec for Insytli and can deliver a secure, production-grade backend in Node.js/TypeScript with Supabase. I’ll implement official OAuth2 flows for Meta, TikTok and YouTube, encrypt access/refresh tokens at rest in Supabase, and centralize token refresh logic server-side. For ingestion I’ll build unified tables (account and media-level) with RLS, a 90-day backfill on first connect, and a 24h scheduler with exponential backoff and detailed sync logs stored in a dedicated table. I’ll provide unit tests, migration scripts, and Git-hosted setup documentation. Technical approach: typed API clients, paginated backfill workers, background job queue, and DB normalization to a platform-agnostic metrics schema so the frontend consumes a single shape. I’ll include deployment notes for Meta App Review and Business Verification steps. Next step: I can prepare an implementation plan and schema draft within 48 hours. Which of the four platforms should be prioritized first for MVP (and do you already have developer/app credentials for any of them)? Best regards, Cindy Viorina
