Describe an interesting product you built.

This question is structured in a way to allow you to showcase your creativity, problem-solving abilities, planning skills, and your ability to execute a vision into a tangible product. You're not only measured on the complexity or the magnitude of what you have built, but also how effectively you undertook the challenge, the steps executed, the thought process, and your ability to iterate and improve the product.

Key points to consider in your answer could include: The need or problem your product was solving, how you identified and validated that need, the process of designing and implementing the product, the challenges faced and how they were mitigated, the final product details and its impact after launch.

An interesting product that I designed and developed was a digitally accessible grocery delivery app for elderly citizens. The idea for this product was inspired by my interactions with my grandparents who found grocery shopping tedious and often faced challenges in carrying heavy groceries.

To begin, I researched their requirements and the existing apps in the market. Most apps had complicated checkout processes and didn't cater to elderly users with features like larger text options or simple UIs. I sketched a preliminary design on paper, incorporated feedback from my grandparents, and then moved on to designing a high fidelity prototype using Sketch.

The development phase posed two major challenges: integrating a payment gateway that allowed for smooth transactions and developing an intuitive UX considering non-tech savvy users. The solution came from incorporating a simple card payment option and rigorous testing with potential users to gather feedback on the app's user-friendliness.

The finished product had a simple-to-use design with features specifically tailored for the elderly; like adjustable font size, a simplified checkout process, and a comprehensive FAQ section. The app was launched locally and gained favorable reviews. My grandparents and their friends now find grocery shopping more comfortable and less strenuous.

The most engaging product I built was an AI-powered Chatbot for a local e-commerce website. The business had been facing challenges with high volumes of customer queries on products, delivery, and return policies that overwhelmed their customer service executives.

After conducting intensive market research to understand how AI could be implemented to address these challenges and considering the project's budget, I decided to use a Machine Learning API to create a chatbot.

During the implementation phase, I faced complications while training the AI for understanding different variations of a single question. Further research led me to use Natural Language Processing to enhance the chatbot's efficiency in understanding and responding.

Once the ChatBot was incorporated into the company's website, there was a significant decrease in customer service demands, with the bot handling 70% of initial query interactions. This not only improved the speed of response for customer queries but also allowed the customer service team to concentrate on more complex queries.

This project provided me learning experiences in AI, Machine Learning, and Natural Language Processing, and it was satisfying to create an effective solution to improve the company's customer service efficiency.
