Implemented a complete Meta Pixel browser-side and server-side event deduplication system to improve conversion tracking accuracy and eliminate duplicate event reporting across Meta Ads.

The client was facing duplicate event tracking issues after implementing Meta Conversion API alongside the Meta Pixel. The goal was to properly configure browser and server events with accurate deduplication logic to ensure clean data collection and reliable ad attribution.

What makes an A/B test readout useful to a product team?
My preferred first page answers four questions:
What changed, and by how much?
How uncertain is the estimate?
Did an important guardrail get worse?
What decision does the evidence support, and what remains unresolved?
A result can be statistically significant and still too small to matter. An inconclusive result can still leave a meaningful gain or loss plausible. The decision needs more than a green badge.
This is a strong framing of experiment readouts: separating signal, uncertainty, guardrails, and the actual decision keeps the team honest. The reminder that significance is not the same as usefulness is especially important.
