Practical insights and guides on PHP/Symfony, React/Next.js, legacy modernization, and software architecture, drawn from 18+ years of building web applications for European businesses.
FrankenPHP collapses the classic Nginx + PHP-FPM stack into a single Caddy-based binary with worker mode, HTTP/3, and embedded PHP. Here is how it actually behaves under production load on Symfony, and the operational realities the hype posts skip.
Read morePrompt injections, hallucinated data, model outages, and latency spikes break LLM features in ways traditional code does not. Here is the defense-in-depth playbook — input guardrails, output validators, circuit breakers, and user-visible fallback UX that quietly absorb the failures customers should never see.
Read moreMost SaaS products claim to support GDPR deletion but ship half-implemented flows — audit logs keep PII, backups still hold full records, the warehouse never syncs the change. Here is what an honest right-to-erasure pipeline looks like in production.
Read moreA pragmatic, load-driven comparison of pgvector against Pinecone, Weaviate, and Qdrant — with concrete thresholds for when to stay on Postgres and when switching actually pays off.
Read moreLLMs cheerfully return malformed JSON, invent fields, and drop schemas the moment traffic spikes. Here is the production playbook — JSON mode versus tool use, validation with retries, streaming, and the safety net that keeps garbage out of your frontend.
Read moreEnterprise buyers are starting to ask SaaS vendors if they support MCP. Here is what the Model Context Protocol actually is, what shipping a server costs, and how to decide between build, wait, or skip in 2026.
Read moreMost RAG demos collapse the moment a real product touches them — wrong chunks, slow queries, no evaluation, no cost ceiling. Here is a Symfony + pgvector blueprint that actually holds up in production, with the architectural choices that matter and the ones that do not.
Read moreMost agentic features that shipped in 2025 disappointed in production. Here is a build, buy, or wait decision framework for B2B SaaS, with concrete architecture patterns for Symfony and Next.js.
Read moreAI features can turn a profitable SaaS into a cash-burning one overnight. Here is a practical engineering playbook for token budgets, prompt caching, model routing, and the fallback patterns that keep LLM unit economics under control.
Read moreMost RAG tutorials stop at a working prototype. This blueprint covers a production-grade architecture using Symfony, PostgreSQL with pgvector, hybrid BM25 + vector search, evaluation, and the operational concerns tutorials skip.
