How does web application and project development progress?

An end-to-end engineering process that understands your business processes, with clear scope, transparent delivery phases, and sustainable code.

We start by clarifying your goals, user roles, and business rules together. After defining the domain model, data flows, and API contracts, we select a technology stack suited to interface, authorization, and performance needs.

Throughout development, we progress with regular demo and feedback cycles; we bring testing, security review, and observability infrastructure online early. After go-live, we help your project stay sustainable with maintenance, monitoring, and iterative development support.

Web application development covers interactive software with login, role-based authorization, data processing, and third-party integrations — unlike a static corporate site. Needs such as admin panels, dealer portals, SaaS products, or internal operations tools fall in this category.

Jettfy builds performant, secure, and SEO-friendly web applications with Next.js, React, and modern backend technologies. Our Izmir-based team offers end-to-end engineering and product development from discovery to go-live; we can also support your existing team as a technical partner.

  • Admin panel, B2B portal, and SaaS product development
  • REST or GraphQL API, secure sessions, and role-based access
  • Fast, sustainable code with Next.js, React, and modern backend
  • CI/CD, logging, metrics, and production environment monitoring

What is web application development, and which projects fall in scope?

Web application development is the process of planning, coding, and launching software that runs in the browser and includes user sessions, databases, and business logic. Unlike a corporate website focused on "reading information," interactive scenarios such as logging in, filling forms, generating reports, managing orders, or internal team workflows take center stage.

Common project types in this scope include admin panels, B2B dealer portals, customer self-service areas, SaaS subscription products, learning platforms, reservation systems, and operations tools integrated with ERP/CRM. In every project, business rules and user roles are clarified first; development then begins with scalable architecture.

At Jettfy, rather than selling ready-made packages, we create a modular roadmap tailored to your needs. Whether MVP for fast market testing or a full-scale corporate portal — transparent phases, code quality, and documentation are standard deliverables in both scenarios.

Which technologies do we use when building web applications?

On the frontend, we prefer React and Next.js: server components, SEO compatibility, fast page transitions, and a modern developer experience are possible with this stack. On the backend, depending on project needs, we design Node.js-based APIs, serverless functions, or integration layers to your existing enterprise services.

In the data layer, relational databases like PostgreSQL, Redis caching, and object storage (e.g. Cloudflare R2) for file management are components we use frequently. Security layers such as authentication, role-based access (RBAC), audit logs, and rate limiting are planned early.

CI/CD pipeline, staging environment, error tracking, and performance metrics are part of production quality. Core Web Vitals and accessibility targets are embedded in the development process, reducing technical debt accumulation after launch.

How do we approach SaaS, B2B portal, and admin panel projects?

In SaaS products, multi-tenant architecture, subscription/billing integration, and onboarding flows are critical. In B2B portals, dealer or customer roles, price lists, stock/order visibility, and ERP connectivity come to the fore. In admin panels, reporting, user management, and content moderation are typical modules.

In every project type, we define the minimum viable product (MVP) scope together in discovery. Unnecessary features are removed from the first release; the core workflow goes live in a stable way. In later iterations, analytics data and user feedback feed the roadmap.

If you need design, you can combine UI/UX and development under the same team with our custom web design service; after launch, you can get sustainable support with project management and maintenance packages.

Frequently asked questions about web application development

What is the difference between a website and a web application?
A website is generally focused on promotion, content, and communication; visitors read information and submit forms. A web application includes login, role-based screens, data processing, and ongoing interaction — such as a panel, portal, or SaaS product. Technical infrastructure, security, and development time also differ accordingly.
How long does a web application development project take?
A focused MVP-level panel is typically 8–12 weeks; a multi-module B2B portal or SaaS product can range from 4–9 months. After discovery, we share a clear schedule based on module list, integration count, and your team structure.
What determines web application cost?
Number of user roles, integrations (ERP, CRM, payment, email), reporting depth, multilingual support, design scope, and hosting/SLA expectations affect price. We offer scope-based quotes instead of fixed packages; you can start with the quote form or a discovery call.
Which technologies do you develop with?
React and Next.js on the frontend; Node.js ecosystem on the API and backend side depending on project needs; PostgreSQL-heavy stack for databases. We can also design integration layers to your existing .NET, Java, or third-party APIs.
Do you integrate with our existing systems (ERP, CRM)?
Yes. Bidirectional or unidirectional data flow can be planned via Logo, Nebim, Salesforce, HubSpot, or custom REST/GraphQL APIs. Integration scope is clarified in discovery; separate time is allocated for testing and error scenarios.
Development only, or design included too?
Both models are possible. If your design files are ready, we can go straight to development; otherwise, our custom web design team produces wireframes, UI, and design system, then hands off to the coding phase.
Do you provide post-launch maintenance and support?
Yes. Within our project management and maintenance service, we offer security updates, monitoring, small iterations, and SLA-backed support packages. Documentation and team handover after go-live are also part of delivery.
