About the Client
Pliroforiki Koufopoulou is a certified exam and computer training center based in Greece, offering a wide range of IT courses, ECDL certifications, and professional development programs. With a strong local presence and years of educational expertise, the center empowers students and professionals alike to enhance their digital skills and achieve industry-recognized certifications.
The Challenge
Pliroforiki Koufopoulou reached out with a clear yet complex request: to transform their Microsoft Access-based internal system into a modern, cloud-ready web application—without disrupting their daily operations. The Access database, which managed student records, exams, schedules, and administrative workflows, was being used locally while the data was hosted in the cloud. However, the client sought greater flexibility, accessibility, and long-term sustainability through a custom-built solution.
The project involved not only replicating the existing functionality but also ensuring that the new application was 100% reliable, modern, and scalable—built using state-of-the-art technologies. And with daily operations at stake, the entire system had to be migrated and launched in just a few hours.
Full System Replication
We were tasked with recreating the entire Microsoft Access environment—its structure, queries, and user flows—within a custom web application. The goal was to make the new platform feel instantly familiar to staff, while running on a completely modern stack.
Data Migration & Integrity
Every bit of data—from student profiles and attendance logs to certification tracking—had to be migrated from Access to a robust MySQL backend, with complete accuracy and zero data loss.
Modern, Scalable Architecture
The new web app needed to be future-proof. That meant building it with modern tools and frameworks, ensuring it was fully cloud-deployable, secure, and ready for long-term use without dependence on legacy systems.
Minimal Downtime
The transition had to be executed quickly and efficiently—outside working hours—to ensure that the team could continue using the system the very next day, now through a seamless web interface.
Our Solution
To deliver a smooth transition from Microsoft Access to a high-performance web application, we engineered a custom platform using a modern, scalable tech stack. The new solution replicated every aspect of the original system while unlocking greater speed, accessibility, and reliability—with zero disruption to the center’s operations.
Custom Web Application Development
We rebuilt the entire system using Angular for a dynamic, responsive frontend and Node.js for a powerful backend. This ensured a fast, secure, and user-friendly experience that mirrored the Access-based interface staff were already familiar with—while making it accessible from any browser or device.
Seamless Data Migration
All data and logic from Microsoft Access were carefully migrated to a PostgreSQL database. We preserved table structures, relationships, and existing queries to maintain full functionality and data integrity, ensuring nothing was lost in the transition.
Scalable & Containerized Architecture
To future-proof the application, we deployed it using Docker, enabling isolated environments, rapid scaling, and simplified maintenance. This containerized setup also improved deployment speed and made updates easier moving forward.
Overnight Deployment with Zero Downtime
The final rollout was performed overnight, leveraging Docker to streamline deployment and ensure system readiness by morning. The client’s staff logged into a fully functional web application the next day—with no training required and no service interruption.
Outcomes & Results
The launch of the new web application delivered immediate and measurable benefits to Pliroforiki Koufopoulou. With improved performance, real-time access, and an intuitive interface, the team experienced a transformation in the way they managed daily operations—resulting in both internal and external growth.
Streamlined Operations
Core processes like student registration, exam management, and data retrieval became significantly faster and more efficient, reducing administrative workload by over 40%.
Improved Accessibility
By moving away from a local setup, the team gained full access to their system from any location or device—enhancing flexibility and reducing bottlenecks during peak hours.
Boost in Team Productivity
With a smoother, faster, and more centralized system, staff productivity increased noticeably. Tasks that previously took hours were now completed in minutes, allowing the team to focus more on delivering value to students.
Increase in Sales & Registrations
The sales growth was a direct result of improved internal efficiency. With the new app streamlining tasks and boosting team productivity, staff were able to handle more student registrations and inquiries in less time—leading to a measurable increase in both enrollment and revenue within weeks of launch.
TheDevalley built a fast, modern, and efficient CRM that became vital to our operations. From the start, the team stood out with their professionalism and full-stack expertise. What really impressed us was their initiative to present a modern design that exceeded expectations—something most developers don’t even offer. Communication was excellent throughout, and the project was delivered without issues. We highly recommend TheDevalley and look forward to working with them again.
