Platform Replatforming

Next.js Migration & Modernization

Moving an existing website or application to Next.js requires more than rebuilding the frontend. We first review the current architecture, content, URLs, data, integrations, functionality, and technical limitations.

Modernization 01

WordPress to Next.js

Rebuild the frontend in Next.js while preserving important content structures, URLs, metadata, redirects, and SEO requirements.

Modernization 02

React SPA to Next.js

Modernize an existing React application where the business needs improved architecture, rendering options, routing, or performance.

Modernization 03

Pages Router to App Router

Refactor an existing Next.js application toward the App Router while reviewing data fetching, component boundaries, routing, caching, and existing functionality.

Modernization 04

Legacy Frontend Modernization

Replace outdated frontend architecture with a more maintainable Next.js structure while protecting the business functionality that already works.

Modernization 05

Existing Next.js Codebase Takeover

We can review and continue an existing Next.js project when a business needs a new development partner, technical improvements, or ongoing feature development.

A migration plan should protect valuable content and functionality while giving the new architecture a clear path forward.

Decoupled Content Architecture

Next.js with Headless CMS

A headless CMS can separate content management from the frontend experience. This can be useful when your content team needs an easy editing system while the website needs a highly customized Next.js frontend. Depending on the project, we can connect Next.js with a suitable headless CMS for:

✓Structured content

✓Dynamic pages

✓Case studies

✓Service content

✓Location pages

✓Resource libraries

✓Editorial workflows

✓Preview and publishing workflows

The CMS is selected around the content model, editorial process, integrations, and long-term requirements rather than added simply because it is popular.

Technical Discovery / Organic Acquisition

Next.js SEO Architecture

SEO should be considered during architecture, especially when organic search is an important acquisition channel. Our Next.js SEO foundation can include:

✓Search-friendly URL structures

✓Page titles and descriptions

✓Dynamic metadata

✓Open Graph metadata

✓Canonical URL handling

✓XML sitemap configuration

✓Robots directives

✓Structured data where appropriate

✓Semantic HTML

✓Internal linking

✓SEO-friendly rendering decisions

✓Image optimization

✓Redirect planning during migrations

Next.js provides built-in capabilities for metadata and different rendering approaches, which can be used as part of a broader technical SEO strategy.

Technical implementation alone does not guarantee rankings. Content quality, search intent, competition, authority, and ongoing optimization still matter.

Engineering Excellence

Next.js Performance & Core Web Vitals

Performance should be considered during development rather than patched after launch. We focus on the parts of the application that can affect real user experience, including:

•Rendering strategy

•Server and client component boundaries

•JavaScript bundle size

•Image and asset delivery

•Data fetching

•Caching and revalidation

•API response efficiency

•Code splitting

•Lazy loading

•Mobile performance

•Core Web Vitals

Next.js supports different rendering approaches for different use cases, such as static and dynamic rendering. The right choice depends on whether content is shared, personalized, frequently changing, or data-driven. We focus on measured improvements rather than promising an arbitrary performance score for every project.

Universal Usability

Accessibility & Inclusive Next.js Development

Accessibility starts during interface and frontend development. Depending on the project, we consider:

✓Semantic HTML

✓Keyboard navigation

✓Focus management

✓Accessible forms

✓Screen-reader support

✓Appropriate ARIA usage

✓Readable interfaces

✓Responsive interaction patterns

Accessibility requirements depend on the audience, project scope, and applicable standards. We address them as part of the design and development process rather than leaving them as a final check.

Production Reliability

Next.js Deployment, Monitoring & DevOps

A completed codebase still needs a reliable path to production. Depending on the project, deployment support can include:

•Production environment setup

•Hosting configuration

•Environment variables

•Preview environments

•CI/CD workflows

•Deployment configuration

•Error monitoring

•Performance monitoring

•Application analytics

•Production troubleshooting

•Release and rollback planning

The deployment approach is selected around the application's architecture, traffic, integrations, operational requirements, and future growth.

Architecture & Platform Stack

Our Next.js Technology Stack

We choose the technology stack around the project rather than forcing every application into the same setup. The final stack is confirmed during technical discovery and architecture planning.

Layer 01

Frontend

Next.js, React, TypeScript, and the frontend technologies selected for the project's requirements.

Layer 02

UI & Design Systems

Reusable interface components, responsive systems, and the styling approach appropriate for the application.

Layer 03

Backend & APIs

Application logic, APIs, databases, authentication, and integrations based on the system architecture.

Layer 04

Data & CMS

The database and content management approach selected around the application's data model and editorial workflow.

Layer 05

Payments & Integrations

Payment services, CRM systems, ERP platforms, external APIs, and other business tools where required.

Layer 06

Deployment & Infrastructure

Hosting, deployment, monitoring, and infrastructure configured according to the application's operational requirements.

Feasibility & Assessment

Is Next.js Right for Your Project?

Next.js is powerful, but custom development should not be the default solution for every website or application. We recommend Next.js when the project benefits from greater control over performance, application architecture, integrations, functionality, or long-term development.

Scenario A

Next.js Can Be a Strong Fit When:

✓The project needs advanced custom functionality
✓Performance and SEO are important
✓The website combines content with application features
✓Custom authentication or user roles are required
✓Multiple systems need to communicate
✓You are building SaaS or a customer portal
✓A headless architecture makes sense
✓The product will evolve significantly over time

Scenario B

A Platform May Be Better When:

•The project is a straightforward business website
•Standard ecommerce functionality is enough
•The team needs a simple managed editing environment
•Existing platform functionality already solves the requirement
•The additional cost of custom development is not justified

Our role is not to sell custom development simply because it is technically advanced. We assess whether it creates enough business value to justify the investment.

Platform Decision Framework

Next.js vs WordPress, Webflow & Other Platforms

The right technology depends on what your website or application needs to accomplish.

Requirement	Next.js	WordPress	Webflow / Hosted Platforms
Custom application logic	Strong fit	Possible with development	More limited for complex logic
Content-driven websites	Strong	Strong	Strong for many use cases
Visual editing	Depends on CMS setup	Strong with the right setup	Strong
Complex integrations	Strong	Strong with development	Depends on available integrations
SaaS / dashboards	Strong fit	Possible with additional architecture	Usually less suitable
Headless architecture	Strong fit	Strong option	Depends on platform
Technical flexibility	High	High with development	Varies by platform
Platform maintenance	More development responsibility	More ongoing management	Lower for many hosted solutions
Best fit	Custom websites, applications, SaaS, portals, advanced systems	Content-driven and extensible CMS websites	Businesses prioritizing managed editing and faster implementation

We recommend the platform based on your requirements, budget, internal team, content workflow, integrations, and long-term plans.

Direct Answers

Frequently Asked Questions

Common questions about our delivery process, technical standards, and engagement models.

How do I know if I need custom development instead of a platform like WordPress or Shopify?+

Custom development makes sense when you have unique business logic, complex data relationships, specific performance requirements, or integrations a platform can't support natively. For most standard business sites or stores, a platform build gets you the same result faster and at lower cost, we'll assess this honestly during consultation.

Why Next.js specifically?+

Next.js is a modern React framework that gives direct control over rendering and performance strategy, with strong support for both content-heavy pages and complex application logic, a combination that suits businesses needing both marketing pages and custom functionality in one system.

Is custom development more expensive than a platform build?+

Generally, yes, custom development involves building functionality from scratch rather than configuring existing tools, which takes more time and technical work. It's a worthwhile investment when your requirements genuinely need it, and an unnecessary cost when they don't.

Can you integrate our custom application with existing business systems?+

In most cases, yes, integrating with CRMs, ERPs, payment processors, or internal tools is a common part of custom development. Specific compatibility depends on the system, so we confirm this during technical discovery.

Do you work with businesses outside Bangladesh?+

Yes, we build custom applications for businesses across Bangladesh as well as internationally, including the US, UK, Australia, Canada, and UAE.
