Every digital project has its own requirements. Sometimes, a new feature needs to be developed for an existing website, several applications need to be connected, or a repetitive task needs to be automated. In other cases, an entirely new platform is needed to support thousands of users, process large volumes of data, and grow alongside the business.
At Webmaster.hr, we provide custom software programming and development services, from individual features and API integrations to complex web applications, business systems, and mobile solutions. We combine modern technologies with practical experience to develop reliable, efficient, and sustainable solutions for the long term.
More than a decade of experience developing our own software products and projects for clients enables us to approach every task with an understanding of both its technical and business aspects. We are not limited to ready-made templates and off-the-shelf add-ons; instead, we develop features tailored to users’ real needs.
From a Simple Feature to a Complex Application
Programming is not just about creating new software. Often, the most useful thing is to improve what already exists, connect disconnected systems, or develop a module that makes a particular task easier for users.
Our development services include:
-
Web application development – building business applications, administrative systems, user portals, and advanced web platforms.
-
Frontend and backend development – building interactive user interfaces, business logic, data processing systems, and administrative tools.
-
API development and integrations – connecting applications, databases, and external services to enable automated information exchange.
-
Module and feature development – enhancing existing applications with new capabilities, from booking and payment systems to document and user management.
-
Business process automation – developing solutions that reduce manual data entry, repetitive tasks, and the chance of errors.
-
Artificial intelligence integration – implementing AI features in existing or new applications.
-
Android app development – developing mobile applications and connecting them to web services and business systems.
-
Modernization of existing software – upgrading outdated technologies, optimizing performance, and adapting applications to new requirements.
We can take over development from the initial idea and architecture definition, or join an existing project that needs additional development resources.
Technologies We Use
For development, we use proven, modern technologies that make it possible to build fast, secure, and scalable applications. We tailor our technology choices to the project’s needs, its existing infrastructure, and its future development plans.
Laravel and PHP are the foundation of our backend development. We use them to build business logic, REST APIs, administrative systems, automated processes, and complex applications that process large volumes of data.
Vue.js and React are used to develop modern, interactive user interfaces, while Nuxt.js and Next.js enable the development of advanced web applications with support for server-side rendering (SSR), performance optimization, and a solid technical foundation for SEO.
For the structure and styling of user interfaces, we use HTML5, CSS3, JavaScript, and TypeScript, and Kotlin for Android app development Kotlin.
For working with data, we use MySQL and MariaDB, while we use Redis when a project requires data caching, faster access to information, or other features that contribute to more efficient system operation.
The development process also involves tools such as Git and Composer, which enable version control, dependency management, and organized project work.
We pay special attention to application architecture. Separating the user interface, API, and business logic enables more flexible development, easier maintenance, and integration of different systems without unnecessary duplication of functionality.
API integrations and business system connectivity
Modern businesses often use multiple applications that process the same or interrelated data. When systems do not communicate, employees have to transfer information manually, check that it is consistent, and repeat the same administrative tasks.
We develop APIs and integrations that connect existing applications with external services, business platforms, and internal systems.
Such integrations may include data exchange with ERP and CRM systems, connecting online stores, synchronizing user data, automated document generation, order processing, and integration with government or other specialized information systems.
One example of our experience is the integration of the business application wMIND with the Occupational Safety Information System (ISZNR), which connects professional and administrative processes with an external information system.
The goal of integration is not only to enable technical communication between applications, but also to simplify the entire workflow and reduce the need for manual data processing.
Artificial intelligence as part of an application
Artificial intelligence opens up new possibilities for software development, especially when integrated directly into existing business processes.
We develop AI integrations that enable users to process content, automate administrative tasks, analyze data, and use advanced language models without leaving the applications they use every day.
In our system wCMS we already use artificial intelligence to translate content automatically, with support for different AI model providers and the ability to control usage.
Depending on the project's needs, AI features can include intelligent document search, data classification, summary generation, content preparation, customer support chatbots, or automated processing of customer inquiries.
A particular advantage of this approach is the ability to connect artificial intelligence with existing business logic and data, while ensuring appropriate user permissions and access control.
Experience proven through our own products and projects
Developing our own software products is an important part of our business. It allows us to test the technologies we use every day in real-world conditions, through working with users, changing requirements, and long-term system maintenance.
Our solutions include wMIND, a modular occupational safety system; wCMS, a web content management platform with webshop and booking modules; DMS for managing business documents; Cjenici.eu for managing and automatically publishing price lists; SMS Promo for managing promotional SMS campaigns; and systems for e-learning, reviewing academic papers, and building management. wMIND, a modular occupational safety system; wCMS, a web content management platform with e-commerce and booking modules; DMS for business document management; Cjenici.eu for managing and automating the publication of price lists; SMS Promo for managing promotional SMS campaigns, as well as systems for e-learning, reviewing scholarly papers, and building management.
We also have experience developing complex media platforms. For the portal ICT Business we developed a new platform based on a Laravel API, a Vue administration system, and a Nuxt frontend application, optimized for more than 700.000 visits per month.
Projects like these require much more than implementing individual features. A high-quality architecture, efficient database queries, loading optimization, caching, reliable operation, and the ability to continue developing the system without compromising existing functionality are all important.
We also apply the experience we have gained to new projects, regardless of their size or industry.
Software Development Outsourcing and Existing Project Development
Not all companies need or are able to maintain their own development team. Some need occasional help from an experienced programmer, while others are looking for a long-term technology partner or additional development capacity.
We offer outsourced programming services to companies, agencies, and organizations that need expert support in delivering software projects.
We can join an existing development process, take on the creation of individual modules, develop an API, resolve technical issues, or help modernize an existing application.
If a project already has its own architecture, database, and development standards, we do our best to adapt to the existing environment. Changing technologies or starting development from scratch is not always necessary to achieve better functionality and efficiency.
We can organize collaboration as a one-off project, the development of a specific feature, or an ongoing engagement with an agreed scope of work.
Development, Implementation, and Long-Term Maintenance
High-quality software must be prepared not only for today's requirements, but also for future upgrades, changes to business processes, and growth in the number of users.
That is why we pay attention to source code structure, security, user access management, database optimization, performance, and testing of key features.
In addition to development, we can also provide suitable server infrastructure through our own web hosting service, technical maintenance, application updates, and further feature enhancements.
This enables clients to receive a complete service, from programming and implementation to hosting and long-term technical support, without having to coordinate multiple service providers.
