Personalized Push Notifications at Scale: Gemini 3 Pro × Firebase Cloud Messaging for Indie App Developers
If your push notification open rates have plateaued, this guide shows how to combine Gemini 3 Pro with Firebase Cloud Messaging to generate per-user copy. Includes the production architecture, working code, PII guardrails, and real cost numbers from a live indie app.
Putting Gemini Embeddings in the Browser — Building a Serverless FAQ Search with IndexedDB
How I shipped semantic search for a few hundred FAQ entries without standing up a vector database. Gemini Embedding runs once at build time, the index sits in IndexedDB, and searches happen in the browser.
Cutting Gemini Embedding's output_dimensionality from 768 to 256 reduced my vector DB storage to one-third
An indie developer's record of trimming gemini-embedding-001 from 768 to 256 dimensions for an 80,000-row wallpaper recommendation index, with measured numbers on storage, cost, recall trade-offs, an int8 quantization implementation, a CI benchmark gate, and the five-step rollout plan I now use in production.
Gemini API: RESOURCE_EXHAUSTED When Sending Large PDFs or Videos via inlineData — When to Switch to Files API
Why the Gemini API returns RESOURCE_EXHAUSTED for large PDFs or videos sent via inlineData, and a practical migration path to Files API based on real indie-developer experience.
What I Tried, In Order, When Gemini API Returned User location is not supported in Production
Hitting the Gemini API from Cloudflare Workers or Vercel and getting hit with a sudden 'User location is not supported' error? Here is the exact order I worked through, drawn from a live production incident on my own indie apps.
Gemini API Returns 400 When You Set tools and responseSchema Together — Three Designs That Make Function Calling and Structured Output Coexist
You want function calling to fetch external data and a strict JSON shape for the final answer. Setting tools and responseSchema together returns 400. Here's why, plus three production-tested designs that make both work.
Why I Always Resize Images With Pillow Before Sending Them to the Gemini API
A practical look at why preprocessing images with Pillow before they reach the Gemini API quietly cuts both latency and token usage. Numbers from a real personal project, plus the helper function I now reuse everywhere.
Build a Voice + Screen-Share AI Pair Programmer with the Gemini Live API in TypeScript
A practical playbook for wiring the Gemini Live API to getDisplayMedia and a microphone to build an over-the-shoulder AI pair programmer in TypeScript, with cost controls and the gotchas I hit in production.
Migrating from Gemini 2.5 Pro to 3.2 Pro in 7 Days — A Production Playbook for Compatibility Testing, Output Diff Scoring, and Rollback Design
A 7-day playbook for moving production systems from Gemini 2.5 Pro to 3.2 Pro: compatibility testing, LLM-as-Judge scoring, shadow traffic, and rollback.
Gemini API DEADLINE_EXCEEDED Errors: Five Things to Check First
When DEADLINE_EXCEEDED suddenly starts spiking on your Gemini API backend, here are the five checks I run first — based on real production debugging.
Building a RAG Evaluation Framework with Gemini API: RAGAS, LLM-as-Judge, and Custom Metrics Production Masterclass
Complete guide to building a quantitative RAG evaluation framework using RAGAS, LLM-as-Judge with Gemini API, and custom domain metrics — including CI/CD integration and production monitoring.
Monetizing Content Production Services with Gemini 2.5 Flash's Low-Cost Advantage
A practical guide to building profitable content production services using Gemini 2.5 Flash's cost efficiency. Covers model routing between Flash and Pro, async batch processing design, and real revenue simulations.
