    We're looking for a technical partner (agency or highly capable team) to help bring an AI + BI insights platform to life. This will be a customer-facing dashboard that aggregates and interprets data from 20+ public sources (e.g., retailer sites, industry reports, social media, scientific databases), which is done through scraping or AI ingesting particular sites and delivers actionable insights for consumer brands.

    The platform will:

    *Scrape and update data regularly (e.g., Sephora, Ulta, brand websites, review sites, social media)
    *Interpret consumer sentiment, product trends, gaps in brand portfolios, market share insights
    *Display insights in modular dashboards
    *Enable comparisons across brands, categories, and time (e.g., week-over-week changes)
    *Use generative AI to summarize reviews, trends, and recommendations

    You'll be working with a product team that will provide detailed mockups and insight logic. We’re looking for a group that brings strong data warehousing, web scraping, AI integration, and front-end development capabilities.

    📽️ A full video walkthrough is included in the post—please review it before responding. - https://www.loom.com/share/c8e4f1d0e3fe40cba51e5688f0fc52ea?sid=67cdd564-10f6-4bbf-9954-f90ed6c839dc

    Looking for:
    ✅ Agency/Team with full-stack capabilities - MUST HAVE comparable experience.
    ✅ Experience building data-driven platforms (across multiple data sources)
    ✅ Ability to move fast and iterate
    ✅ Will look at independent individuals if you have teams or other partners you can bring with you.

    MVP:
    * Filter at the top to filter brands, products, and/or category and then hit "analyze" to create AI insights for selected criteria
    * data warehouse well architected and organized
    * ~20+ sites scrapped, and more added to the pool over time
    * 5-10 strong insights surfaced per page for 2-3 pages

    Note this is MVP which I want to launch as fast as possible and then will be continuing to grow the data library and pushing out more insights as we go.

    **DO NOT EMAIL ME OR CALL ME OUTSIDE OF UPWORK - I WILL NOT WORK WITH THOSE THAT DO**

    Please include in your response:

    * Relevant examples of similar projects
    * What tool you plan to use that could allow us to leverage open source code and move quick (e.g. do you have something for data visualization you prefer using for good looking visuals?)
    * How you'd approach an MVP

    Meta Ads API Developer for Internal Creative Automation Tool

    About Us
    BINA is a high-performance marketing group scaling lead generation campaigns across Meta. We’re building an internal tool to streamline static ad production, deployment, and creative testing. We’re looking for a technical partner who has already built robust systems on top of Meta’s Marketing API and understands how to move fast, clean, and with a strong sense of ownership.

    What You’ll Be Responsible For
    • Using Meta’s Marketing API to:
    • Extract Campaigns, Ad Sets, and Ads
    • Clone and create new Ad Creatives, Ad Images, and Ads
    • Managing asset libraries, permissions, and creative uploads using AdImage, AdCreative, and Ad objects
    • Handling token authentication (system user, access tokens, long-lived tokens) and app review requirements
    • Ensuring proper creative upload and review flow for compliance
    • Supporting creative rotation at scale using batch requests
    • Building lightweight endpoints or worker scripts to connect with our automation system
    • Setting up robust error handling, retries, and clear logging for success/failures in ad creation
    • Naming conventions and metadata tagging that support downstream performance analysis

    Must-Have Experience
    • Production-level use of Meta’s Marketing API: you’ve created and launched ads programmatically, not just pulled reports
    • Managing creative approvals and troubleshooting rejections
    • Handling token refresh, app review, and system user permissions under a Business Manager
    • Strong fundamentals in async processing, queues, and rate limit management
    • Able to pair-program / co-build in real time (“vibe coding”)
    • Comfortable working in Node.js or Python (FastAPI preferred)

    Nice to Have
    • Insights API experience for reporting rollups
    • Experience with Conversions API setup
    • Slack webhook or app integrations
    • Familiarity with image storage (e.g., S3 or Cloudinary)
    • Experience building tools for media buyers or marketers

    Who You Are
    • You’ve already built Meta Ads automation tools or dashboards from scratch
    • You can explain exactly which Marketing API objects you’ve worked with
    • You know how to debug creative rejection errors, rate limits, and token failures
    • You speak our language: you know what CTR, CPL, and creative fatigue mean
    • You like building fast with minimal meetings, strong documentation, and async progress

    To Apply
    Start your message with “StaticScale 2025” or it will be skipped.

    Include in your proposal:
    1. Specific examples (repo/code sample) of Meta Marketing API work
    2. Description of a tool or workflow you built that used the API to create ads
    3. List of Marketing API objects you’ve used
    4. How you handle rate limits, retries, and idempotency
    5. How you manage access tokens and Business Manager connections
    6. Your hourly rate and weekly availability
    7. Optional: Loom video walking through one of your past builds

    We’re hiring for someone who’s done this before. Please do not apply if you’re learning the Meta API for the first time. This is not a generic dev job — we need real experience with Meta’s ad infrastructure.
