A Practical Guide to Mobile App Performance Budgets

Cold start, frame time and battery draw are product features. Treat them like features and give them budgets.

Performance work fails when it is a cleanup task. It succeeds when a number is agreed up front and a build that exceeds it does not ship.

Pick three numbers

Cold start to first meaningful paint, 95th-percentile frame time, and background battery draw per hour. Three numbers a whole team can hold in its head.

Enforce them in CI

A budget nobody measures is a wish. Instrument a real device in CI and fail the build on regression, exactly as you would for a failing test.

Spend the budget deliberately

Budgets are not about always being fast. They let you say yes to an expensive animation because you know precisely what it costs.

Building something like this?We do this work for a living — tell us what you are trying to ship and we will tell you honestly whether we are the right team for it.

Hybrid search + reranking for RAG isn’t a free win: prove it with margin‑gated evals (or don’t ship it)

Hybrid search + reranking for RAG isn’t a free win: prove it with margin‑gated evals (or don’t ship it)

Hybrid (BM25 + vectors) plus a cross‑encoder reranker is now the default RAG advice, but it can make real systems worse. Here’s a practical, eval-driven way to decide when to rerank using similarity margins and failure-mode buckets.

The Permission Boundary Pattern: least-privilege tool-using agents without keys to prod

Tool-using agents fail differently to chatbots: they can cross system boundaries. The Permission Boundary Pattern gives you an implementable blueprint for agent identities, per-tool scopes, short-lived credentials, and end-to-end auditability so overreach is detectable and revocable.

Hybrid retrieval for RAG is the new baseline: stop vector-only failing on SKUs, error codes and policy text

Hybrid retrieval for RAG is the new baseline: stop vector-only failing on SKUs, error codes and policy text

Vector-only RAG fails in predictable places: IDs, SKU-like tokens, exact clauses and compliance language. A production hybrid stack (BM25 + dense + reranking + ACL-aware filtering) fixes this, and you can prove it with a simple evaluation harness.
