Engineering knowledge built around production decisions

Engineering Insights is a practical knowledge base for founders, product leaders and technical teams evaluating AI, mobile, SaaS, security and backend development. The goal is to explain the architecture decisions that affect budget, reliability, security and delivery speed before those decisions become expensive to reverse.

Use the guides to compare implementation approaches, prepare vendor questions and understand which capabilities belong in an MVP versus a production platform. Every article connects back to the relevant service or solution page so a research question can lead directly to an architecture discussion when a real project is ready.

The collection is deliberately focused on buyer intent and engineering evidence rather than generic technology news. Topics include AI agent cost, RAG versus fine-tuning, secure WebRTC, SaaS architecture, mobile product cost, vendor selection, product security and the path from MVP to scalable operations.
