Journey

Unfortunately, the company I was working for had a layoff, so I am constantly looking for my next position, but the hiring process is different at every company. But I have found that there are common questions asked in every interview, and I have started to write down these questions to improve for my next interviews. As part of the hiring process, some companies ask you to record a video answering some questions, and this process can be intimidating. Inspired by this, I created an AI interview simulator that generates questions based on your role and provides feedback using your phone and camera to give you a close experience to real interviews.

The application features an Angular-based frontend, utilizing Tailwind CSS for styling and Angular CDK for component primitives, enhancing the UI development process. The backend is powered by HonoJS, a lightweight JavaScript framework, and integrates LangChainJS to manage interactions with large language models efficiently. For the infrastructure, the app leverages Cloudflare’s ecosystem: Cloudflare Pages for hosting, Cloudflare Workers for edge functions, and Workers AI Models including @cf/openai/whisper for audio processing, @cf/meta/llama-2-7b-chat-fp16 for chat functionalities, and openai-tts for text-to-speech capabilities. Data storage is handled via Cloudflare R2, and D1 provides a scalable database solution for managing chat memories and other data needs.
