Introducing Coffee Compass

 Luxury Coffee Project Blog post

 

 

1. Introduction

 

The purpose of our "Luxury Coffee Online" project was to provide an e-commerce platform for a high-end coffee retailer, enabling customers to browse, purchase, and track the delivery of their coffee orders. It is a solo project, my primary focus was on integrating real-time shipment tracking with major shipping providers like UPS and FedEx, a crucial feature for enhancing the user experience and building trust in our service.

 

2. A Personal Story

 

I enjoys riding bicycles, so it was an easy project focus to agree upon. For me, bicycling has always been a passion that connects me to my roots. I grew up in a small North-of-african town surrounded by farms and forests, and the only way I could visit my best friend in the next town over was by riding my bicycle. On weekends and holiday breaks, I would get up at the break of dawn and bike for over an hour to her place. The road I took was lined by corn fields on both sides, with the sun rising on the left. Whenever I bike in the city now, it brings back these hours I spent chasing the brightening horizon at dawn, with the smell of the harvest around me. I hope that by making bicycle route planning more accessible through our project, more people, especially city-dwellers, can learn the joy that bicycling can bring to their lives.

 

3. Accomplishments and Architecture

 

To provide our users with accurate and up-to-date delivery information, we integrated real-time shipment tracking with the APIs.

 

For the backend, we chose to use Django, a robust Python web framework, due to its comprehensive features and the team's familiarity with it. This allowed us to quickly build the middleware that handled API requests and responses, standardized the data from different shipping providers, and managed the caching mechanism to comply with rate limits.

 

One of the key features we implemented was the ability for users to view the current status of their orders and track their packages directly from their account dashboard. This was achieved by seamlessly integrating the real-time shipment data, providing customers with a smooth and transparent order fulfillment experience.

 

Additionally, we focused on ensuring the reliability of the shipment tracking feature by implementing extensive error handling and fallback mechanisms. This allowed us to gracefully handle scenarios such as network failures or temporary unavailability of real-time data, ensuring that users could still access the last known status of their orders.

 

4. Overcoming a Technical Challenge

 

One of the most difficult technical challenges I faced during this project was integrating the real-time shipment tracking with the. The initial hurdle was handling the different authentication methods required by each provider. To address this, I developed separate authentication modules for each service, thoroughly testing the token refresh and request authentication processes.

 

Another challenge was ensuring data consistency. The responses differences in status codes, delivery estimates, and error messages. To unify this data, I created a mapping system that translated the various responses into a standardized format for our application's database schema. This involved writing custom parsers and validators to handle the nuances of each provider's API.

 

However, the most significant obstacle was the API rate limits imposed by UPS and FedEx. Frequent polling for tracking updates led to requests being throttled, which threatened the real-time nature of the feature. To mitigate this, I implemented a caching mechanism that stored tracking updates locally and only queried the shipping providers at intervals compliant with their rate limits. This approach reduced the frequency of API calls while ensuring users received timely updates.

 

Throughout this process, I encountered several moments of frustration, particularly when dealing with the inconsistencies and constraints of the third-party services. However, by remaining persistent and methodical, I was able to overcome these challenges and successfully integrate the real-time shipment tracking functionality into our application.

 

5. Lessons Learned and Future Approaches

 

This project has taught me several valuable lessons that will inform my approach to future engineering endeavors:

 

Technical Takeaways:

- Understanding and accommodating the constraints of third-party services is crucial for successful integration. Factors like rate limiting, authentication methods, and data consistency must be carefully managed.

 

What I Might Do Differently:

- In the future, I would consider implementing a more sophisticated queuing system for API requests to better manage rate limits and provide more granular control over how and when requests are made.

- I would also explore the use of webhooks provided by the shipping services, which could push updates to our system, reducing the need for frequent polling.

 

Personal Growth as an Engineer:

- This project taught me the importance of persistence and problem-solving. Working through the challenges reinforced my ability to remain patient and methodical, as well as the value of robust error handling and extensive testing.

 

Informing My Engineering Path:

- This experience has highlighted the significance of understanding the ecosystem in which an application operates, particularly when integrating with external services. Moving forward, I will approach similar projects with a stronger emphasis on planning for third-party constraints and incorporating more resilient design patterns.

 

Confirming Beliefs:

- This project confirmed my belief in the importance of thorough documentation and a solid understanding of API specifications for successful integration. It also affirmed my preference for Django as a backend framework, as its comprehensive features proved invaluable in handling the complex data interactions required for this feature.

 

• In conclusion, integrating real-time shipment tracking was a challenging but immensely rewarding experience. It taught me valuable lessons about handling third-party integrations, managing API constraints, and the importance of robust error handling. These lessons will undoubtedly inform my future projects and contribute to my growth as an engineer.
