Engineering guides, architecture patterns, and production implementations focused on Roas.
Why observational attribution models and platform dashboards inflate ROAS by measuring correlation rather than causation: designing matched-market geo-holdout tests, synthetic counterfactual baselines with CausalImpact, and exposing non-incremental retargeting and branded search cannibalization.
The hidden auction physics of landing page latency: how a 3.0s mobile load time triggers a 150% Google Ad Rank CPC penalty, bleeds 38% of paid mobile clickers before pixel initialization, and how sub-500ms Next.js 15 edge architectures restore 10/10 Quality Scores and double conversion rates.
How modern algorithmic ad auctions penalize saturated creatives: analyzing the physics of Meta Advantage+ and Google PMax auction formulas, leading telemetry indicators (First-Time Impression Ratio and Hook Rate decay velocity), and automated Python fatigue detection pipelines.
Our engineering team designs sub-50ms distributed backends, edge AI pipelines, and high-concurrency systems.
