Your cache is not the problem — your invalidation is
Most teams tune TTLs when what they actually need is to know which keys a write touches. Here is the registry pattern we use on every Django project.
Hnin Ei PhyuRose IT designs and engineers mobile apps, web platforms, desktop software and 2D games for teams who need to move fast without breaking what they already have. One senior team, four disciplines, shipped in weeks — not quarters.

We take four kinds of work because those are the four we are genuinely excellent at. Everything else, we will happily refer you elsewhere.
Every case study here names the client, the constraint and what changed. No anonymous logos, no invented metrics.
Most software projects fail on communication, not on code. So the process is built around the opposite: written scope, two-week sprints, and something installable every fortnight.
We map the problem before anyone opens an editor. Stakeholder interviews, a walk through your existing system, and a written scope you can hold us to.
3–5 days
Data model, API contract, infrastructure plan and the decisions worth arguing about — all written down before they get expensive to change.
1 week
Wireframes to a full design system, prototyped and clickable. You approve screens, not adjectives.
2–3 weeks
Two-week sprints against a public board. Every sprint ends with something you can install and use — not a status update.
6–14 weeks
Load testing, security review, accessibility audit and a rehearsed rollback plan. The boring fortnight that decides how launch week feels.
1–2 weeks
We ship it, watch it, and stay on. Monitoring, on-call, and a monthly report that says what actually happened.
Ongoing
We pick tools with long support horizons and large hiring pools, so the thing we hand over is still maintainable by someone who is not us in three years.

CeleryEvery quote below is from a named person at a named company about a project on this site.
We had been told by two previous vendors that an eleven-second cold start was "a platform limitation". Rose IT got it to 1.4 seconds and showed us exactly why the old number was never a limitation at all. They are the first agency we have worked with who argued us out of a feature because it would not survive contact with our users.

Our dispatchers were reconciling four systems by hand and a WhatsApp group. Rose IT spent the first two weeks watching them work before writing any code, and it shows in every screen. Dispatch went from twenty minutes to under thirty seconds and we did not add a single person.

VP Operations · Kaizen Logistics
Every previous vendor built us something that worked in their office. Rose IT built something that works in a village with one bar of signal, because that is where our patients are. Adherence more than doubled. That is not a software metric to us — it is people taking their medication.

Black Friday used to be a two-day manual scale-up and a war room. This year it was eleven times baseline traffic and nobody stayed late. The franchisee pricing console alone removed two thirds of our support volume.

Two hundred editors migrated off a tool they had used for twelve years, in six weeks, with no rollback. I did not think that was possible. It opens a 4K project in about a second, and the offline annotations mean our remote editors are finally equal citizens.

Head of Post-Production · Lumen Studios
We came in with a mechanic that tested well for five minutes. Rose IT told us the mechanic was fine and the meta-game was the problem, then modelled the fix before building it. Day-30 retention is double the category benchmark. They were right and we were wrong.

Long-form posts from the people doing the work. No listicles, no thought leadership.
A 30-minute call, no deck. You describe the problem, we tell you honestly whether we are the right team for it — and what it would realistically cost.
