Web applications we develop

Web icon.

Enterprise web applications

Enterprise web applications handle complex workflows across departments, from resource planning to reporting. They’re built to match how your organization operates rather than forcing a one-size-fits-all model on it.

Customer-facing applications

Customer-facing applications give your users direct access to account management, bookings, and self-service tools, even as your user base grows.

Web portals give partners, vendors, or clients a secure space to access shared information, submit requests, and track progress, all in one place.

We design SaaS products as multi-tenant platforms built to onboard users quickly, scale efficiently, and support subscription billing and usage tracking from day one.

Our e-commerce applications combine product catalogs, checkout flows, and inventory management into a single system built to drive conversions and long-term growth.

Supply chain and operations applications

These applications track inventory, shipments, and day-to-day operations across supply chains, keeping the departments of large enterprises in sync.

Performance optimization icon.

Analytics and data applications

We create dashboards, reports, and forecasts using raw data. Your teams can use them to make informed decisions, shape strategies, and adjust their plans based on real-time insights.

Advanced technology apps icon.

Advanced technology apps

For businesses looking to go a step further, we build web applications that connect to IoT devices, add AI features such as AI chatbots, or integrate AR and VR capabilities, extending what a browser-based tool can do.

Web application security and compliance

  • Authentication and authorization

We set up multi-factor authentication and single sign-on for login, plus role-based access controls that determine who can view, edit, approve, or export each record.

  • Data encryption

Sensitive data is encrypted both in transit and at rest, closing off the most common paths to a breach and reducing the risk of unauthorized access.

  • Secure software development practices

Security management covers every stage of development, with code reviews, dependency checks, and automated security testing.
  • Security testing

Before launch and on an ongoing basis, we run vulnerability scans and penetration tests to catch security weaknesses and verify fixes.

  • OWASP

Our development process follows OWASP guidelines, addressing the vulnerabilities responsible for most real-world web application breaches.

  • Relevant compliance standards

Depending on your industry, we build in the controls needed to support compliance with regulations and standards such as GDPR, HIPAA, and PCI DSS.

Web application development process

Discovery and requirements

Our experts gather requirements, define goals, and identify constraints.

Architecture and planning

Next comes planning the architecture, technology stack, and integrations that will support your application as it grows.

UX/UI design

We design interfaces and user flows focused on clarity and ease of use for your specific audience.

Development

Our developers build the application in iterations, with regular check-ins so you can review progress.

Integration

We connect the application to the third-party systems and data sources it needs to work with.

Testing

The application goes through functional, regression, performance, and security testing, plus cross-browser and cross-device checks.

Deployment

We deploy the application to your chosen environment and help make the move to production go smoothly.

Support and evolution

If needed, our team stays on to monitor performance, fix issues, and add features as your needs evolve.

FAQ

A website mainly presents information, while a web application lets users interact with data and complete tasks. A company site describes services, but a web application might let a customer log in, submit a request, and track its status. The line blurs on complex sites, but the deciding factor is whether the tool processes user input and business logic rather than just displaying content.

Most custom web applications cost between $25,000 and $150,000 or more, depending on scope. The main cost drivers are the number of user roles, the complexity of business logic, how many systems the app needs to integrate with, and the amount of custom design work involved. A detailed estimate follows a discovery phase where we map out your specific requirements.

Simple web applications typically take two to four months, mid-size applications take four to eight months, and complex or enterprise-level applications can take eight months or longer. Timelines depend on scope, integration requirements, and how much of the design and business logic is already defined before development starts.

Yes, integrating with ERPs, CRMs, and other business systems is a routine part of our web application development work. We connect through APIs or middleware depending on what the existing system supports, so data moves between systems without manual re-entry.

We design the architecture to scale from the start, using cloud infrastructure, load balancing, and database strategies suited to your expected growth. This means the application can handle more users and data over time without requiring a full rebuild.

We apply authentication and authorization controls, encrypt data in transit and at rest, follow secure coding practices guided by OWASP, and run security tests before launch. For regulated industries, we also build in the controls to support compliance with regulations and standards such as GDPR, HIPAA, or PCI DSS.
