Application development
Everyone uses Next.js now. That is not the differentiator. What separates a fast, findable application from an expensive single page app is which rendering strategy each route gets and who decided that before the design was signed off.
What is next.js development at The Cubas?
Next.js development at The Cubas means server rendered React applications built on the App Router with TypeScript throughout. Search architecture, structured data and a performance budget are designed into the build rather than retrofitted, so the site launches ready to rank instead of needing rescue work six months later.
When people call us
The call usually comes from one of two places. A React app that renders nothing until JavaScript loads and therefore ranks for nothing, or a marketing site on a page builder that cannot be made fast no matter what is spent on hosting.
Built by
Ashraful Islam Hridoy, Lead Engineer
Ashraful builds the systems behind The Cubas engineering work, from typed REST APIs and data models to the React interfaces on top of them. His focus is the part most builds skip: secure access, reliable background jobs, and what happens to a system after launch.
What people search before they call
We rank for these ourselves. That is the shortest demonstration available that the search side and the build side are the same team.
How we approach it
Four decisions that separate a build which holds up from one that needs rescuing inside a year.
Static generation for content that rarely changes, server rendering where data must be fresh, client rendering only where interactivity genuinely requires it. Applying one strategy to every route is how applications end up slow and unfindable at the same time.
Most of an application does not need to ship JavaScript to the browser. Keeping client boundaries at the leaves rather than the layout is the single largest lever on bundle size, and it is a structural decision that cannot be retrofitted cheaply.
TypeScript across the interface, the API and the data layer, with runtime validation where external input arrives. The compiler catches the refactor you forgot; validation catches the payload you did not expect.
Limits on bundle size, image weight and render blocking work, checked as part of shipping rather than measured afterwards in a report nobody actions.
Deliverables
No tiered packages with features withheld to force an upgrade. Every engagement covers what the project genuinely requires.

Evidence
Not a capability list. Systems in production, described by what was genuinely hard about each one.

Hotel booking from search to payment
A booking application covering listing discovery, reservations, property management and payment, with seeded demo accounts so anyone can walk the full flow.
Questions
Next.js renders HTML on the server, so a crawler receives content without executing JavaScript. A plain React application sends an empty shell and depends on the crawler to run the bundle. Google usually manages that, most AI crawlers do not, which makes server rendering the safer default for anything that needs to be found.
Yes. We start with an audit of routing, rendering strategy, data fetching and bundle composition, then produce a prioritised list of what to change. Taking over a codebase without that step is how teams inherit problems they did not budget for.
A marketing site with a defined content set typically runs three to six weeks. An application with authentication, roles and a real data model runs longer and depends almost entirely on how settled the requirements are rather than on the framework.
