Postgres Row-Level Security for Multi-Tenant SaaS: When It's Enough and Where It Quietly Breaks
Postgres RLS can enforce tenant isolation at the database layer—but connection pooling, SECURITY DEFINER functions, and Doctrine quirks create gaps that bite teams in production. Here's where RLS holds and where it doesn't.
LLM Observability on a Budget: The Minimal Stack for Debugging AI Features in Production
When an AI feature misbehaves in production, standard APM dashboards are useless. Here is the minimum viable LLM observability stack for small engineering teams — prompt capture, cost attribution, and the alerting rules that actually predict AI incidents.
Prompt Injection Defense for B2B SaaS: Beyond Input Sanitization With Defense-in-Depth Patterns
Input sanitization stops the obvious attacks and almost nothing else. Indirect prompt injection through RAG documents, tool outputs, and multi-turn context is the threat most B2B SaaS teams are not ready for. This post covers the production defense stack: structural prompt separation, tool-use allowlists, user-scoped permission propagation, output constraints that catch data exfiltration, and the red-team harness enterprise buyers will ask to see.
Hybrid Search in Postgres: Combining pgvector and Full-Text Search Without Elasticsearch
Pure vector search misses exact queries. Pure BM25 misses paraphrased intent. The production answer is hybrid — and for most mid-size SaaS, the right place to do it is inside Postgres itself.
WCAG 2.2 Level AA in React and Next.js: The Engineering-Level Accessibility Audit Before EAA Enforcement
The European Accessibility Act enforcement gap closes mid-2026, and the WCAG 2.2 AA checklist your product manager hands to engineers rarely survives contact with a real React component tree. This is the engineering-level audit: focus management in Next.js App Router, criteria that Radix and Headless UI quietly fail, form error announcements that work with real screen readers, and the CI setup using axe-core and Playwright that catches regressions before they ship.
EU-US Data Privacy Framework in 2026: The Engineering Contingency Plan If Schrems III Lands
The EU-US Data Privacy Framework has held since 2023, but Schrems III litigation is already in motion. If the CJEU invalidates the framework again, EU SaaS teams will need a plan they built before the ruling — not after. This guide covers the engineering decisions that make your product survivable: abstracting provider boundaries, leaning on SCCs as belt-and-braces cover, routing EU subprocessors through EU-only infrastructure, and building a real cross-border data flow inventory.
