Invite Club
Web-based app that revolutionizes the process of sending and receiving invitations
Requirements
Our solution
Invite Club needed to finally move away from chaotic development cycles and get a product foundation they could trust.
We restructured the application into a maintainable, modern architecture, replacing patchwork code with stable React and Node.js practices.
After trying different teams, the app had fragmented logic and inconsistent design. The founders needed a partner who could align technical execution with their business vision.
Migrated from a split user-role concept to a unified approach, simplifying user experience and scaling needs while reducing long-term maintenance costs.
The client wanted not just fixes, but a codebase that could evolve, scale, and support growth without constant rework.
Transitioned to functional components, modernized Material UI, and applied best practices that ensure the app can grow without regressions.
Given the app revolves around payments and personal event data, Invite Club required strong security and reliable DevOps support.
Beyond development, our team involved DevOps expertise to resolve SSL/TLS issues, harden security, and guarantee uninterrupted access for users.
About Invite Club
The application boasts a sleek UX/UI design and offers all the essential features needed for organizing and participating in various prestigious events:

Built using Node.js and React, Invite Club ensures high performance and security. Additionally, it offers seamless scalability, making it ideal for MVP development stages.
Why Invite Club Hired Lengin Developers
Before we joined the project, it had undergone over a year of development. The client had attempted collaboration with several other development providers, all of whom had not demonstrated sufficient quality and dedication. The primary issue revolved around subpar engineering quality, characterized by inadequate decision-making and execution, mainly on the front end.
The application featured an acceptable back end built with Node.js. However, the React front end was disorganized, utilizing a mixture of old and new approaches, including both functional and class components. This resulted in performance issues and posed challenges for future maintenance.
Following comprehensive research and consultations, Invite Club decided to entrust the entire development process to Lengin developers for the following reasons:
Invite Club had experienced unsuccessful collaborations with other development companies.
They required a high level of expertise to address existing problems.
They sought a long-term partnership to avoid the need for constant developer switches.
Testing the App: Over 1000 Errors
As mentioned previously, Invite Club reached out to Lengin due to a negative experience and unsatisfactory results obtained from hiring developers from less reputable vendors. They contacted Lengin because their project required extensive expertise in JavaScript, specifically Node.js and React, to address existing issues, as well as for ongoing development and maintenance.
Upon our engagement with Invite Club, the initial step involved conducting comprehensive testing of their application. The application exhibited numerous alerts, with Google Search Console alone reporting over 1000 alerts.
Concept of UX/UI Design And Functionality
Since Invite Club is an application that is specifically focused on certain tasks, its functionality and design are minimalist, aiming to address questions related to the organization and participation in various events to the maximum extent.
When we joined the project, the application had a concept of dividing users into participants and event organizers, each with different functionalities. However, after some time, our client decided to merge these roles, making some modifications and combining functionalities, as it simplifies the maintenance and scaling of the application.
Reengineering Into a New Functional Component Approach
In our work on the Invite Club app project, we encountered a mix of old-class and new-functional component approaches in React. This led to challenges in code complexity, maintainability, and performance. To overcome these issues, we migrated the project entirely to the modern functional component approach using React Hooks. This transition enhanced code readability, simplified testing, and brought the project in line with the latest React practices, ensuring its long-term viability and scalability.
We initially encountered on the project a combination of both old and new versions of the Material-UI library. This presented challenges in terms of consistency, maintenance, and compatibility. To resolve these issues, we made the decision to migrate the project exclusively to the latest version of Material-UI.
Event Drafts
While we refined and enhanced much of the existing functionality, implementing various fixes, primarily on the front end, we also developed new features. One of them was the development of the back end and front end for event drafts, which synchronized with the payment system, profile database, shared calendars, and other data to facilitate clear event organization and participation.
Involving DevOps to Solve SSL Certificate Issues
We ran into some problems with our SSL certificate. To beef up our security efforts, we brought in a skilled DevOps specialist.
One tricky issue we encountered was related to the certificate chain. It turns out that issues with intermediate certificates, like them being missing or not configured correctly, can be a real headache. These problems can lead to trust issues, where the certificate isn’t recognized as valid by our clients.
Another challenge we faced was managing the private key that’s linked to the certificate. This key is super important, and any problems like losing it, compromising it, or using it incorrectly can be a real nightmare to sort out. Sometimes, we even had to go through the process of reissuing and reconfiguring the certificate, which can be quite complex.
Lastly, making sure that the cipher suites we choose are both secure and compatible with various client devices and browsers proved to be a bit of a puzzle. It required a deep understanding of cryptography and a watchful eye to maintain security while keeping everything compatible.
Results:
→ Transformed a fragile, inconsistent codebase into a solid, maintainable platform that Invite Club could confidently continue scaling on.
→ Reduced over 1,000+ technical errors through rigorous testing and code refactoring, significantly improving SEO health, loading speed, and cross-browser reliability.
→ Implemented secure infrastructure with SSL/TLS optimization and streamlined DevOps practices, ensuring enterprise-grade data protection and uninterrupted platform uptime.
