About this gig

You used AI to build a Power BI custom visual. Now it's glitchy, slow, or failing certification and you don't know why.

I'm Shannon, founder of Datellers and one of the few developers with AppSource-certified visuals live on Microsoft's marketplace. I've built 100+ custom visuals from scratch using the Power BI Visuals SDK, TypeScript, D3.js, and pbiviz. I know exactly where AI-generated code breaks.

What I'll do in a review:

  • Audit your update() method for performance issues and redundant renders
  • Check data binding, dataView mapping, and role handling for correctness
  • Review your formatting pane (capabilities.json + property handlers) for API compliance
  • Identify selection, highlight, and cross-filter contract violations
  • Flag TypeScript anti-patterns, unused imports, and dead code
  • Assess AppSource certification readiness if needed

What you'll get:

  • Written review report (inline comments + summary doc)
  • Fixed/polished source code (Standard and Premium tiers)
  • Clear explanation of every change no black box fixes

Who this is for:

  • Developers who used AI to generate a visual and need a senior eyes check
  • Teams preparing a visual for AppSource submission
  • Businesses whose visual works "mostly"
