Process

Development Process (3 Steps)
There can be weekly meetings as needed. this is just a miniamalist version of the process of design and development.
This structured 3-step development process ensures a smooth transition from design to a fully functional product. Each phase includes key development milestones, testing, and iterative refinements to ensure quality, scalability, and performance.
Step 1: Development Planning & Setup
Goal: Establish the technical foundation and set up the development environment.
Design Consultation – Define design needs, branding, colors, type and iconography for the App
Technical Kickoff Meeting (1 Hour) – Define tech stack, database structure, and API requirements.
Codebase Setup & Architecture Planning – Establish development environment, repositories, and initial frameworks.
Backend & Frontend Framework Selection – Choose technologies based on scalability and project needs.
Deliverables:
Initial Mood board, user journey, Personas
Development roadmap with milestones
Initial project setup (GitHub, CI/CD pipelines)
Backend database structure and API documentation
Step 2: Core Development & Integration
Goal: Build the platform’s core functionality and ensure seamless interactions.
Frontend Development – Develop user-facing interfaces based on final design files.
Backend Development – Implement data storage, authentication, and API integrations.
Feature Implementation – Develop key functionalities such as dashboards, payment gateways, and user accounts.
Internal Testing & Debugging – Run unit tests, functional tests, and security checks.
Deliverables:
End to End Design in Figma with completed branding
Fully functional front-end and back-end with integrated APIs
User authentication and security protocols
Performance and security optimizations
Revisions: Internal testing and two client feedback rounds
Step 3: Testing, Deployment & Handoff
Goal: Ensure quality, optimize performance, and launch successfully.
Final Review Meeting (1 Hour) – Align on final testing, bug fixes, and deployment strategy.
User Testing & Quality Assurance – Conduct beta testing, usability reviews, and security audits.
Deployment & Optimization – Deploy to staging, run final tests, and launch the product.
