Paper for above instructions

Project Development Challenges and Solutions

In any web development project, challenges are inevitable. Recently, I completed a project involving the development of a web application utilizing Angular (version 14), a .NET RESTful Web API (C# version 6), and SQL Server (version 2019) as the backend database.

Challenges Faced

One of the significant challenges I encountered was managing the interplay between the frontend (Angular) and the backend (.NET API). The data fetching processes were slow when the application was first deployed, making user interactions sluggish. This led to frustration among users who expected applications to be responsive and quick.

Overcoming the Challenges

To address the performance issues, I implemented caching mechanisms within my application architecture. Caching optimizes data retrieval by storing frequently accessed data temporarily, reducing the frequency of database accesses (Friedman et al., 2021). I utilized built-in Angular services to cache API responses for a specified time, allowing users to access data without waiting for the server. This solution notably reduced load times.
While implementing caching provided immediate benefits, it required me to make compromises. Specifically, I had to ensure that the cached data was consistently updated with the latest information from the server. This necessitated additional logic for invalidating the cache when updates occurred. I justified this sacrifice because the compromise offered a substantial increase in performance, thereby enhancing user experience (Davis, 2022).

Alternative Solutions

Considering alternatives, I evaluated employing a content delivery network (CDN) for asset management and static file hosting. While CDNs can vastly improve performance for static resources, for server responses, the caching approach directly addressing the data fetch issues from our .NET API was more valuable as it decreased server load and optimized performance more effectively for our specific needs (McMillan, 2020).

Caching in UI Design

In the mentioned project, I used caching to enhance performance significantly. I set up an Angular service that intercepted all HTTP requests, checking if the requested data already existed in the cache before re-fetching it from the API. For implementation, I utilized Angular's HttpInterceptor, which allowed me to manage request interception and response caching seamlessly.
By caching data such as user profiles and frequently queried data, the application demonstrated a marked improvement in user experience, cutting data retrieval times down to milliseconds instead of seconds. The combination of these approaches allowed me to clear significant hurdles in application performance.

Contributions to Technical Design

When tasked with implementing a design provided by a technical lead, it is crucial to approach it critically. One of my contributions in past assignments was analyzing our RESTful API's resilience and proposing the adoption of asynchronous programming patterns.

Scenario

For instance, during a project involving an API for a task management tool, I observed that synchronous methods were leading to blocking issues during peak loads, which could significantly degrade performance. I recommended implementing asynchronous methods for API calls, allowing requests to process independently and enhancing throughput.
This recommendation added value as it maintained application responsiveness, even under heavy load. By utilizing asynchronous capabilities in C#, I managed to significantly reduce latency (Fowler, 2018).

Application Modernization Considerations

Modernizing an application entails various considerations, notably improving functionality, user experience, security, and compliance with current technology standards. An appropriate candidate for modernization is typically a legacy system facing user complaints about performance or difficulty in integrating with new technologies.

Example Project

In a recent modernization project I spearheaded, we transitioned an older invoicing application initially built with Windows Forms to a web-based Angular application supported by a RESTful .NET API. This fundamental change allowed for improved accessibility, enabling users to access the application via various devices without the need for local installations.
The modernization led to enhanced collaboration among team members by centralizing data on the cloud, allowing real-time updates (Kraemer, 2023). Additionally, it improved the user experience by introducing modern design principles, vastly improving the application's usability and aesthetics.

Design Considerations for Full Module Development

In another project, I was responsible for developing a user authentication module. Key design considerations included security measures (e.g., password hashing) and ensuring a seamless user experience during the sign-in process.

Advantages and Disadvantages

Advantages of the chosen design included strong security through hashing algorithms and the incorporation of multi-factor authentication, providing additional security layers. Conversely, the module's complexity can lead to longer development times and necessitate rigorous testing processes (Shen et al., 2019).
After evaluating various design considerations such as user experience and security, I opted for this design because it balanced security needs with user accessibility.

Performance Troubleshooting in Production

In a production environment of the same Angular application, performance problems arose when user transactions slowed drastically. Utilizing Chrome Developer Tools, I diagnosed excessive time on three critical API calls and identified a slow-running SQL query in the backend.
By reviewing SQL execution plans and indexing strategies, I was able to rewrite the query to improve performance and significantly reduce lag times in API responses (Heitritter, 2020). This experience underscored the importance of regularly monitoring application performance and performance profiling to quickly catch inefficiencies.

Troubleshooting Long Load Times

For troubleshooting a reported issue where users experienced extended load times with the AngularJS application, my first step involved reviewing network requests using the browser's developer tools. I monitored response times for each request to the .NET API.
Next, I drilled down into database performance by aggregating logs to identify any unusually long-running queries and check for missing indexes that could have contributed to delays (Parker, 2021). I also investigated frontend issues such as heavy dependency loads that could affect rendering performance.

Conclusion

Through experience in developing and maintaining web applications, I have faced various challenges that tested my problem-solving skills. By leveraging caching, proposing design improvements, and regularly troubleshooting performance issues, I contributed positively to project outcomes and enhanced user experiences. Modernizing legacy applications is crucial for business sustainability, ensuring systems remain efficient and accessible to users who require quick and reliable functionality.
