Our Application Development Services

At Weichie.com, our team of experts offers a wide range of application development services to meet your needs – including, but not limited to:

Custom Web Applications

Need a powerful web-based software tailored to your business? We build custom web applications from the ground up to fit your unique processes and goals. Using robust frameworks like Laravel, our developers create secure, scalable web apps with clean code and engaging user interfaces. From internal dashboards to customer-facing portals, we deliver web solutions that streamline your operations and delight your users.

Native Mobile Applications

Reach your customers on their favorite devices with polished mobile apps. We develop native mobile applications for iOS and Android that offer intuitive user experiences and high performance. By leveraging cross-platform technologies such as Ionic and React Native (Expo), we accelerate development without compromising quality – your app will look and feel right at home on every device. We handle everything from responsive UI design to testing on real devices and App Store/Google Play deployment, giving you a smooth path from idea to a live mobile app.

Application Replatforming

Make your applications more powerful by connecting them with the tools you already use. We specialize in API and external integrations to link your app with third-party services and software. Need to process online payments or sync customer data? We can integrate Mollie for seamless payments, connect to CRMs like Teamleader or Salesforce, integrate marketing platforms such as HubSpot, and much more. By letting your web or mobile app talk to other systems, we automate workflows and ensure you have all your data in one place – saving you time and effort. (After all, “work smart, not hard!”)

Security & Performance Optimization

We build applications with security and performance in mind from day one. Our team follows best practices to protect your data and users – from secure coding standards and data encryption to regular security audits and updates. We also fine-tune every aspect of your application for speed and reliability. This means optimizing databases and code, implementing caching and CDN strategies, and performing load testing to ensure your app runs smoothly even under high traffic. With our focus on security and performance optimization, you can trust that your web or mobile application will be fast, stable, and safe against threats.

Hosting & Maintenance

Launching your application is just the beginning. We offer reliable hosting and ongoing maintenance to keep your app running flawlessly. Our team can host your web application on secure, high-performance servers or set up cloud infrastructure tailored to your needs. We also provide continuous maintenance: monitoring uptime, performing regular backups, applying security patches, and updating your app to stay compatible with new browsers or OS updates. Whether it’s a web portal or a mobile app, we ensure it stays up-to-date, secure, and fully supported post-launch – so you can focus on your business while we handle the tech.

Our Application Development Process

Together, we'll turn your vision into a successful application.

Step 01

Planning & Strategy

Every great application starts with a solid plan. In this phase, we take time to understand your vision, business objectives, and user requirements. We kick off the project with a discovery session – either at our Brussels office, in New York, or via video call – where we brainstorm ideas and gather all necessary requirements. Based on these insights, we craft a clear strategy and project roadmap. This includes choosing the right architecture and tech stack for your app (for example, deciding on a Laravel backend or evaluating if Ionic/Expo is the best fit for your mobile needs) before development begins.

Kickoff Meeting & Brainstorming – We dive deep into your ideas and goals.
Requirements Gathering – Define features, target users, and success criteria.
Solution Architecture – Outline the app’s structure and components.
Tech Stack Selection – Choose the optimal frameworks and tools (backend, frontend, mobile).
Integration Planning – Identify any third-party systems or APIs to connect.
Project Timeline – Create a development timeline with clear milestones.

Step 02

UX/UI Design & Development

With a plan in place, we move into the design and development phase. Our UX/UI designers start by creating wireframes and high-fidelity mockups, giving you a preview of the application’s look and feel. We focus on intuitive navigation and engaging design, ensuring a seamless user experience.

Once the design is approved, our development team gets to work. Front-end and back-end development happen in tandem — we code the interface and functionality using best practices to guarantee a stable, high-quality app. Our developers work closely with the designers to match every detail and ensure the final product meets your expectations. Throughout this stage, we perform iterative testing to catch issues early and keep the project on track.

UX/UI Prototyping – Crafting the user interface design and experience flow.
Front-end Development – Coding the app’s client side (web interface or mobile UI).
Back-end Development – Building the server, database, and API logic.
Integrations Implementation – Connecting APIs and third-party services.
Continuous Testing – Regularly testing features as they are built.
Performance Tuning – Optimizing code and design for speed and responsiveness.

Step 03

Deployment & Launch

Before your application goes live, we make sure every detail is tested and ready for prime time. You will have access to a staging environment or test build to review the app and provide feedback. We perform comprehensive QA testing – checking for bugs, verifying usability, and ensuring the app performs well under load.

When it’s go-time, we handle the entire deployment process. For web applications, we deploy the code to the live server or cloud platform of your choice, set up your domain and SSL certificate, and configure caching or CDNs for optimal load times. For mobile applications, we prepare the app for release on the Apple App Store and Google Play Store (including all the necessary app store listings and compliance checks). Our team coordinates the launch closely with you to ensure a smooth rollout with minimal downtime or surprises.

Staging & Beta Testing – Provide a test version for you (and selected users) to evaluate.
Quality Assurance – Full QA pass to fix any bugs and polish the user experience.
Launch Deployment – Go-live on production servers or app stores.
Domain & SSL Setup – Configure your web app’s domain, SSL security, and DNS (if applicable).
App Store Submission – Handle App Store/Play Store submissions and approvals for mobile apps.
Post-Launch Monitoring – Keep an eye on the live application to ensure everything runs smoothly.

Step 04

Aftercare & Continuous Support

Our relationship doesn’t end at launch – we stand by our work with ongoing support. As users begin to use your application, we closely monitor its performance and stability. We offer maintenance plans to keep your app up-to-date and secure, applying software updates, security patches, and quickly fixing any issues that arise.

We can also roll out new features or enhancements as your business grows and needs evolve. You’ll receive analytics insights and regular performance reports to stay informed on how your app is doing. Whether it’s adjusting for a new iOS/Android release or optimizing a feature for better engagement, we provide continuous support to ensure your application’s long-term success.

Routine Maintenance – Ongoing app updates, bug fixes, and performance improvements.
Monitoring & Alerts – Continuous tracking of uptime, speed, and security.
Security Updates – Timely patching to keep the application safe.
Feature Enhancements – Implementing new features based on user feedback or business needs.
Analytics & Reporting – Tracking usage and providing insights for data-driven decisions.
Dedicated Support – We’re available for any questions, training, or consulting you need.
