#Introduction

• Overview: The CST Goods-In System is designed to streamline inventory management and customer check-in processes. The application was built to address inefficiencies in supply chain operations, making the process faster and more reliable.
• Responsibilities: As a Contractor Fullstack Mobile Developer, I was responsible for developing both the backend and mobile frontend, integrating APIs, and ensuring the overall functionality of the system.

#The Problem

• Context: CST faced significant delays and operational costs due to inefficiencies in their goods-in and inventory management processes.
• Challenges: The primary challenge was the manual and time-consuming process of handling purchase orders and customer check-ins, which required a robust solution to automate and streamline these tasks.

#The Solution

• Approach and Strategy: Developed a mobile application using React Native for the frontend and FastAPI for the backend. The solution integrated seamlessly with ConnectWise APIs for data management and used a serverless architecture to ensure scalability.
• Implementation:

  • Backend Development:

    • Utilized FastAPI and Python for backend development.
    • Integrated ConnectWise REST APIs for data fetching and updates.
    • Employed MongoDB for database management.
    • Added backend tests for reliability.
    • Deployed the backend on Render and used Sentry for bug notifications.
    • Implemented API version control and tested with Swagger.

    

  • Frontend Development:

    • Built the mobile application using React Native.
    • Employed Expo for building, deployment, and submission to the Apple Store.
    • Used Gluestack UI for frontend components and Redux for state management.
    • Incorporated Expo SDKs for functionalities like camera access and asynchronous storage.

  • Features:

    • Delivery Process: Options for full or partial delivery, with printing of labels and slips.
    • Customer Check-In: Ticket management, including damage reporting with photo uploads.
    • User Authentication: RFID scanning and PIN entry for secure access.
    • Automated Notifications: Email notifications for received items and updates.

  • Tools Used:

    • Programming Languages: Python, JavaScript (TypeScript)
    • Frameworks: React Native, FastAPI
    • Databases: MongoDB
    • Cloud Services: Render
    • Utilities: Git, Docker, Figma, Jira, Expo SDK , Sentry

#The Outcome

• Results:

  • Reduced inventory processing time from a full day to under 5 minutes.
  • Improved workflow efficiency and reduced operational costs by 30%.
  • Successfully deployed the application on Apple devices, ensuring smooth user experience.

• Problems Solved:

  • Automated and streamlined the delivery and check-in processes.
  • Enabled real-time data updates and notifications, enhancing operational transparency.
  • Provided a scalable and secure solution for inventory management.
