Web Application Development

It depends on what the application has to do. Server-rendered React through Next.js suits content-heavy products where first-load performance and search visibility matter; Angular suits large applications with many teams and a preference for strong conventions; Vue sits between them. If your team already works in one of these, that is usually the deciding factor — inheriting a stack nobody in-house can maintain is a bad trade.

Often yes, and it is usually the better option. Performance problems, in particular, tend to concentrate in a small number of queries, bundle decisions and rendering paths. Measuring before rebuilding frequently shows the application is sound and a handful of specific things are not.

By measuring the things users experience — how long until the page is useful, how long an interaction takes to respond — rather than optimising a score. That usually means server rendering where it helps, splitting code so the first load carries only what it needs, caching deliberately at each layer, and fixing the database queries behind the slowest screens.

Yes, and we prefer to. When the same team owns the API contract and the interface consuming it, the mismatches that cause most integration delay simply do not arise. We can also work front-end only against an API your team owns.

That is an explicit goal. We work in mainstream frameworks rather than proprietary abstractions, document architecture decisions as we go, and can run a transition period where your engineers work alongside ours before taking over.
