Bun vs Node.js for Next.js in 2026: Production Performance and the Migration Reality
Bun can run Next.js in production now, and the startup and install numbers are real. Whether that matters for your SaaS depends on where the time goes. Bun vs Node.js for Next.js: real workloads, compatibility gaps, deployment changes, and migration cost.
React 19 Compiler: What It Does, What It Doesn't, and When to Enable It
The React 19 compiler automates the memoization you used to hand-write with useMemo and useCallback. Here is what it really changes, where it gives up, how to turn it on in Next.js and Vite, and how to roll it out on a large codebase without a surprise.
Fine-Tuning vs RAG vs Prompt Engineering: The LLM Customization Decision Framework
Prompt engineering, RAG, and fine-tuning solve different problems. A practical framework for choosing between them, with cost comparisons and the build vs managed service question for each.
Software Estimation: Why It's Hard and How to Do It Less Badly
Estimates fail for predictable reasons: unknown unknowns, the planning fallacy, and a habit of confusing effort with duration. Here are the techniques we use to estimate client projects with honest uncertainty ranges, and the contract shapes that keep a bad estimate from sinking the relationship.
Symfony Cache Component: HTTP Caching, Application Cache, and the Patterns That Make Them Work Together
Symfony ships three caching layers that most teams treat as one. Here is a mental model for HttpCache, the Cache contracts, and the Doctrine result cache, plus a Redis setup that survives a multi-tenant dashboard without stampedes or stale data.
Architecture Fitness Functions: Automated Quality Gates for SaaS Codebases
Fitness functions turn architecture agreements into CI checks that fail the build when a boundary breaks. Five concrete examples for Symfony and Next.js teams, with code.
