Application Development Process in Tonjoo
At Tonjoo, we believe every great application must be built on a solid technological foundation. Our core stack consists of a stable and scalable backend using Laravel/Python, paired with a fast and responsive user interface built on React JS.
These two components are connected through a headless architecture, allowing the frontend and backend to evolve flexibly without limiting each other. The entire ecosystem is then containerized using Docker to ensure consistency across every environment and simplify deployment, whether on the cloud, a VPS, or on-premise.
With this foundation, each development stage is executed in a structured and efficient manner. Here’s how Tonjoo implements its application development process.
1. Discovery & Strategy
The first step in building an application is consultation and planning (Discovery & Strategy). This stage is crucial as it lays the groundwork for the entire development process. During this phase, Tonjoo helps clients explore their needs, understand their business objectives, and define the right strategy.
The steps in this stage are:
- Initial Contact: Prospective clients reach out to Tonjoo through any of our communication channels, whether it’s WhatsApp, email, or a direct visit to our office.
- Preliminary Analysis: If the client does not yet have an application, the Tonjoo team conducts market research first. If the client already has an application, we will perform a technical audit and analysis. To do this, our team uses tools like Google Lighthouse, Ahrefs, and Postman to identify performance, security, and integration requirements.
- Requirement Gathering: This is the stage where Tonjoo holds meetings to thoroughly understand the client’s needs. These sessions cover crucial aspects of the future application, including business goals, success metrics, and key features like authentication, push notifications, dashboards, third-party integrations, and more. We also discuss target platforms (mobile, web, or both), along with security requirements, scalability, and regulatory compliance, such as GDPR (General Data Protection Regulation) and HIPAA (Health Insurance Portability and Accountability Act).
- Architecture Design: Based on our discussions, our team will create a data flow diagram, an API contract, and select the technology stack. Tonjoo has extensive experience using Laravel or Python for the backend and React JS for the frontend.
- Initial Design Concepts: To give clients a clear visual idea, Tonjoo prepares two UI/UX concepts for the application’s homepage, complete with design rationales. This allows clients to choose a visual strategy that aligns with their branding.
- Project Proposal: Once the planning is complete, the findings are compiled into a final document that outlines the scope of work, a detailed cost breakdown, and the project timeline.
As soon as the proposal is approved, the creative process begins. The next step is for the design team to start the UI/UX design phase.
2. UI/UX Design
After agreeing on the strategy and foundational framework with the client, Tonjoo translates the plan into a professional visual design. In this phase, our focus is on creating an intuitive user experience, ensuring visual consistency, and simplifying the onboarding process.
Here are the steps in this stage:
- Kick-off Meeting: Once the proposal is approved and the contract is active, Tonjoo holds a kick-off meeting to align on the project vision, user journey, and key UX metrics, such as conversion rate and time to task.
- Wireframing & Mockups: Our design team begins creating wireframes and mockups for each module. Examples of modules include login, dashboard, reports, settings, and others as required. These are created for both desktop and mobile versions.
- Interactive Prototyping: To simulate the application’s workflow, we create interactive prototypes using Figma or Adobe XD.
- Feedback & Revisions: The initial design version is reviewed with the client. This stage includes an iterative process of testing and refining the application until the final design is approved.
Once the final design is approved, high-resolution mockups are handed over to Tonjoo’s professional development team to begin the application development phase.
3. Application Development
In the application development phase, the approved mockups are transformed into a fully functional application. This process is carried out by a professional development team consisting of frontend, backend, and quality assurance specialists.
The steps in this phase include:
- Front-end Development: The front-end team focuses on implementing the UI/UX design using React JS. Our approach is tailored to the application’s complexity. For simple applications, Tonjoo uses pre-configured foundations like CRA or Vite to accelerate the development process. We use Tailwind CSS to create visually consistent and appealing interfaces. For medium-complexity applications, we add State Management to handle data and a Router for page navigation. For the most complex, high-performance applications, we implement a headless architecture where React JS communicates with a Laravel or Python backend via GraphQL or a REST API. We also implement techniques like code-splitting, lazy loading, or Server-Side Rendering (SSR) with Next.js when needed.
- Back-end Development: The back-end developers build the application’s server-side logic using the Laravel (PHP) or Python (FastAPI/Django) framework, depending on the project’s complexity. All application data is stored in a database, for which we use MySQL or PostgreSQL for structured storage, and Redis for caching to speed up data access. If necessary, we can also implement a NoSQL database like MongoDB for more flexible data structures. To enable communication between the backend and front-end, we use an API Layer adhering to RESTful API or GraphQL standards, which defines communication endpoints for core functionalities like authentication, data management (CRUD), reporting, and push notifications. For security, Tonjoo uses JWT/OAuth2 for digital access control, rate limiting to prevent attacks, input sanitization to clean incoming data, and audit logging to track important activities. We also ensure the application can connect with other services through third-party integrations, such as payment gateways, email services, notifications via Firebase Cloud Messaging (FCM), or internal company systems like ERP/CRM.
- DevOps & Containerization: In this phase, our focus is on creating an efficient workflow from coding to server deployment. We implement Docker, which allows us to package every application component—from the frontend to the database—into isolated units called containers. This collection of containers is then managed using Docker-Compose for simple environments or Kubernetes for large-scale applications. This process is automated through CI/CD (Continuous Integration/Continuous Deployment). Using GitHub Actions or GitLab, every code change automatically goes through build, test, and deployment stages to staging or production without manual intervention. If the client prefers, we also support On-Premise Deployment, meaning the entire technology stack can be installed and configured directly on the client’s servers, complete with installation documentation.
- Quality Assurance (QA): The Quality Assurance stage involves testing to guarantee the application’s quality. This process starts at the fundamental level with Unit & Integration Testing using Jest (frontend) and PHPUnit/Pytest (backend) to ensure each component works correctly both individually and when combined. The application’s performance is then tested via performance testing with k6 or JMeter to measure latency, throughput, and stability under heavy load. Finally, we conduct security testing using OWASP ZAP or Snyk to find and fix security vulnerabilities before the application is launched.
The results of the QA process form the basis for the next stage: User Acceptance Testing (UAT).
4. User Acceptance Testing (UAT) & Refinement
Before the public launch, Tonjoo conducts final testing and refinement. UAT is the stage where the client can verify that every feature in the application functions perfectly. This is a collaborative effort with the client to review the application’s performance, functionality, and appearance, ensuring it’s ready for launch.
The steps in this stage include:
- User Acceptance Test (UAT): We invite the client to test the application in a staging environment. This phase covers all business scenarios, such as user registration, transactions, report generation, and more.
- Bug Fixing & Refinement: Based on the testing results and client feedback, the Tonjoo team makes necessary improvements. This may include fixing UI bugs, optimizing performance, or adding minor required features.
Once the testing and refinement process receives the client’s approval, the application is ready to be launched.
5. Launch & Integration
The Launch & Integration stage is the final process where the application is officially released to the public.
The steps at this stage include:
- Deployment: Deployment is the process of moving the application containers to the production environment, whether it’s on the cloud, a VPS, or an on-premise server.
- Technical Configuration: Next, we handle the technical configuration. This includes setting up the domain, installing an SSL/TLS security certificate, activating a CDN like Cloudflare to accelerate global access, and configuring the server as needed.
- Monitoring & Observability: To ensure the application remains healthy, we integrate monitoring and observability systems using Grafana-Prometheus to track performance metrics, Sentry for real-time error tracking, and the Elastic Stack for log analysis.
- Final Check: Before handing over the application to the client, we perform a final check to verify all critical functions and ensure performance meets Tonjoo’s strict standards: a UI response time under 200ms and API latency under 500ms.
- Optimization: As a final step, we perform optimizations through database query fine-tuning, cache layer refinement, and security hardening. This is essential to guarantee the application runs fast, is stable, and remains secure.
After all these processes are complete, the client’s application is live and accessible to the public with fast performance, a robust security system, and full optimization.
6. Post-Launch Support & Maintenance
Tonjoo’s support doesn’t end after the application is launched. We understand that applications need updates over time. That’s why Tonjoo provides post-launch services to ensure the client’s application remains secure and provides a seamless user experience.
The steps in this stage include:
- Routine Maintenance: This service covers regular updates, such as framework and security patches, and database backups. Outdated frameworks and security patches are common vulnerabilities exploited by hackers. This service also includes routine performance monitoring.
- User and Admin Training: In this phase, Tonjoo provides training sessions for the client’s team so they can manage the application independently. The client’s team will learn how to manage the admin dashboard, adjust configurations, and perform basic troubleshooting.
- Ongoing Technical Support: The Tonjoo team is ready to assist if the client encounters any technical issues. We offer a 24/7 SLA that guarantees a rapid incident response for any critical problems that may arise. This support also includes continuous development, such as adding minor features and providing architectural scaling consultations if the application’s load increases.
Overall, these six stages of the application development process represent Tonjoo’s commitment to ensuring that our applications not only operate flawlessly but also support our clients’ business goals.
Application Development Timeline Estimation
The time required to build an application varies greatly depending on the complexity of its features, design, and overall project scale. Here is a general estimation based on Tonjoo’s experience:
1. Low Complexity
For an application with low complexity, such as an MVP (Minimum Viable Product) with 3-4 basic modules, the estimated development time is around 2 months.
2. Medium Complexity
An application of medium complexity, which may include features like multi-API integrations, push notifications, and role-based access, generally takes 3-4 months to complete.
3. High Complexity
For a highly complex application involving a microservices architecture, an enterprise-scale system, or handling high transaction volumes, the development time starts from 5 months or more, depending on the scale and depth of the required features.
