Layering Gemini API Response Caches in Three Tiers — How I Split Memory, Redis, and Context Cache

Cursor's New Model on Coding Agent Index, and Why I Still Pick Gemini as My Center of Gravity
A third-party evaluator, Coding Agent Index, recently rated a new Cursor-developed model as 'frontier-class performance at one-tenth the cost.' I walk through how a solo developer who keeps Gemini at the center of their stack should read that ranking, and where to add the new model without churning the rest of the workflow.

Why per-turn generationConfig is ignored in Gemini API chat sessions
If you pass a different generationConfig (temperature, max_output_tokens, response_schema) to each send_message in a google-genai chat session and the behavior never changes, this walkthrough shows what is actually happening, why the SDK is designed that way, and three workarounds we use in production for review-summary and reply-draft pipelines.

Running an SLO and Error Budget for the Gemini API as an Indie Developer — Guarding Four Sites with Burn-Rate Monitoring
Notes from running the Gemini API inside four production sites as an indie developer. A practical SLO and Error Budget design that fits a single-person operation: Cloudflare Workers and KV for burn-rate calculation, simplified multi-window alerts, and decision rules for what to freeze when the budget runs out.
A Daily Slack Digest of Six Apps' Store Reviews, Built with Gemini Flash
How I built a Cloud Run + Gemini Flash ETL that translates, classifies, and prioritizes 30–80 daily store reviews across six apps and posts them to Slack — cutting my review triage from 60 minutes to 12, for about $4 a month.
Fixing NotebookLM Audio Overview When It Generates in the Wrong Language or Stalls Mid-Way
Five concrete causes and fixes for when NotebookLM's Audio Overview ignores your source language, freezes on the progress bar, or cuts off mid-playback — written from hands-on use during app review analysis.
Replying to 11 Languages of Google Play Reviews With Gemini Without Sounding Like a Bot
After two major Android updates, I had to clear a backlog of unanswered Google Play reviews in Japanese, English, Traditional Chinese, Korean, Thai, Italian, Russian, Persian, Ukrainian, and Polish. This is the operations design I settled on for using Gemini as a translation and vocabulary partner without losing the human temperature.
Letting Gemini Flash Decide continue / pause / rollback for Staged Rollouts: An Indie Developer's Three-Signal Engine
How I built a Gemini Flash decision engine that reads Firebase Crashlytics, App Store / Google Play reviews, and AdMob revenue together, and outputs continue / pause / rollback for each staged rollout across six indie apps. Numbers from two months of production use included.
