Open-Source Online Testing Platform -- 3

@NaveenSingh09

Hello, Building a fully self‑hosted, open‑source testing platform that supports multilingual speech and text interactions is well‑aligned with my expertise. My approach starts with a Docker‑based microservice architecture: a FastAPI backend for exam logic, a Django admin for content management, and a Vue/React front‑end powered by the Quizx framework. Speech processing will be handled by open‑source libraries such as Vosk and Coqui TTS, ensuring no external APIs. I will integrate multilingual text‑to‑speech, speech‑to‑text, and NLP modules for grammar checking and essay evaluation. The platform will feature timers, word counters, auto‑save, and a modular question bank that supports MCQs, audio, video, and fill‑in‑the‑blank types. All code will be clean, documented, and containerized for easy deployment on Hetzner VPS. I am ready to start immediately and would appreciate the opportunity to discuss details. Best Regards Naveen Thakur

As an experienced full-stack developer, I'm confident that my skills match your project's unique requirements. I have a deep understanding of Python and its frameworks like Django and FastAPI, which will be crucial for the development of your online testing platform. Additionally, my expertise in Speech Recognition and NLP and integrating AI models lends me the ability to help you accomplish functionalities like reading aloud tests, audio-speaking tests, and even text processing in multiple languages. Beyond technical capabilities, my understanding of deploying systems on Linux VPS, especially on platforms like Hetzner, compliments well with your project's need for a fully self-hosted testing platform. Extending this further, I have hands-on experience in Docker-based deployment as well as working with open-source libraries exclusively- two aspects that align perfectly with your project's vision.

I recently delivered a project with this exact scope, focusing on a clean, professional, and user-friendly online testing platform using only self-hosted, open-source libraries. Your need for seamless integration of speech processing and AI-driven multilingual text-to-speech aligns perfectly with my expertise. While I am new to freelancer, I have tons of experience and have completed similar off-site projects involving Python (FastAPI/Django), speech recognition, NLP, and scalable, Docker-based deployments. I understand your emphasis on automated exam features, modular code, and mobile responsiveness. I would love to chat more about your project! Regards, MN Williams

With my 6+ years of experience in Python, I'm confident that I can make your vision of a self-hosted online testing platform a reality. My skills extend not only to using ready-made scripts, but also to adapting and customizing them to suit your specific needs. Moreover, my familiarity with open-source libraries is in perfect alignment with your project requirements. Of particular relevance, I have a strong background in Speech Recognition and NLP, both of which are essential for the successful implementation of core functionalities like Speech Processing, Read Aloud Tests, and Repeat Sentence/Audio Speaking Tests. Additionally, I've worked extensively with AI model integration for languages such as English, French, German, Spanish, Hindi, Punjabi, Bengali - providing me with the necessary readiness for the Multilingual AI features requested. Lastly but importantly, I value clean, documented code and understand the necessity of a fully self-hosted and dependency-free deployment. My dedication to streamline designs could be further demonstrated by Docker based deployment. Moreover, being mobile responsive yourself is like hitting two targets with one bullet - this coupled with my WordPress website development skills might help us ensure a seamless user experience across all devices. lets hop up on the chat and discuss the budget and timeline regards Aftaies shah.B
