Custom Web Application Development
I design and develop custom web applications for businesses and professionals. From internal management tools to complete digital platforms, I build tailored solutions that streamline workflows and support business growth.
Web Applications Built Around Your Business
If your team tracks the same work across spreadsheets, email and separate systems, a web application can give everyone one place to work. I start by mapping who uses the system, what they need to do and which information they need along the way.
For CRM, case management and internal workflows, explore my custom business management software. For online sales, explore my custom e-commerce development.
What I Can Build
Business management software
A shared workspace for customer records, cases, documents or appointments, with access based on each user’s role.
Administrative dashboards
Dashboards that surface activity and statistics, with search and controls for the people managing the system.
Digital platforms and portals
Account-based portals where customers or collaborators can submit requests and access the information they need.
API and database integrations
Connections to APIs and databases so your application can exchange and reuse information across systems.
Modernization of existing applications
A review of the system you already use to identify which interfaces, backend components or workflows to update and what needs to carry over.
Technologies and Expertise
Backend
PHP and Laravel for application logic, user permissions and data handling. I also work with Node.js and Express.js.
Frontend
Web interfaces built with HTML, CSS and JavaScript, using React, Angular or Vue.js where the application calls for it.
Databases and tools
MySQL for relational data, Git and GitHub for version control, and technical documentation to support handover.
My Development Approach
Define the scope
We identify who will use the application, which workflows it needs to support and what matters most for the first release.
Design and build
I design the data structure and interfaces, then build the features we agreed on.
Test and hand over
I check the main user flows, access permissions and planned integrations, and prepare technical documentation.
