About Development articles

Technical articles for developers and for the technically curious people who manage them. Framework and architecture decisions, the trade-offs behind them, and the specific mistakes that are common enough to be worth naming.

These lean towards explaining mechanisms rather than listing steps. Knowing that a JWT payload is readable, or why re-saving a JPEG degrades it, changes how you build things far more durably than a tutorial you follow once and forget.

Topics range across the stack — front-end frameworks, APIs and authentication, data formats and encoding, build tooling and performance. Where something has a well-known failure mode, we name it rather than leaving it implied: the JWT that anyone can read, the MySQL column that silently truncates emoji, the URL parameter that breaks the first time a customer types an ampersand.
