Technology problem solver
Framework-specific issues (e.g. Next.js cache revalidation, Supabase RLS recursion, Stripe webhook idempotency) require developers with specialized mastery.
Inspect framework configurations, dependency versions, and runtime logs.
Implement best-practice patterns recommended by official framework maintainers.
Verify sub-second response times and zero regression across the user journey.
Framework problems have a strong tendency to be either fifteen minutes or three days, with very little in between, and which one it turns out to be depends almost entirely on whether the person has seen it before.
That is the argument for paying more per hour on a stack-specific problem. Someone who recognises the failure mode charges for an afternoon; someone learning it charges for a week and may still arrive at a workaround rather than a fix.
The quality of the first reply scales directly with the quality of what you send.
For an urgent problem a workaround is often correct — get past it now, understand it later. The failure is not choosing the workaround, it is forgetting that you did.
Whenever one is applied, get it written down with the reason. Undocumented workarounds accumulate into a codebase where nobody can tell which strange decisions were deliberate.
A large share of framework problems arrive without anyone having written any code, when a dependency updated and changed behaviour. This is why the question 'what changed?' is more useful than it sounds when the honest answer feels like 'nothing'.
Keeping dependency updates deliberate and separate from feature work makes these far easier to trace, and is worth the small ongoing discipline.
Because the time is spent understanding rather than building, and that time varies enormously with familiarity. Someone who has seen the failure before charges for an afternoon; someone meeting it for the first time may spend a week.
Usually yes, for exactly that reason. On stack-specific problems the higher rate typically produces a lower total, because the hours collapse.
