Temet

Know yourself using AI. Allow specialists to help you. Improve your life.
Python Django Machine learning AI CI/CD Large Language Model (LLM) REST API AWS S3 EC2 AI Agent React FastAPI

Temet is your privacy-first AI assistant that lives on your computer. Its main power comes from its ability to read, understand, and help you work with your own documents, securely. Add folders from your computer to give Temet context. Once a folder is "indexed", the AI can answer questions based on its contents, summarize documents, and more. Examples: For a lawyer: Add a folder of laws and contracts and use AI to cross-examine both. For a doctor: Have patients share their medical history folders for a complete, AI searchable overview. For you: Use voice chat to create a daily journal, with each entry saved as a file in a "Diary" folder so you can ask questions about your objectives and milestones. Your data never leaves your computer unless you choose to share it. When you share a folder, Temet creates a direct, encrypted peer-to-peer connection to the other user's app. No central servers are involved in the transfer.

Your scientific content-sharing platform
Python Django Bootstrap AWS Docker docker-compose Nginx SSL Cloudflare CI/CD EC2

This personal project was born from lessons learned on my other sustainability project, IDETRA. The platform allows you to connect data points (posts) to create a storytelling arch with multiple possibilities or assemble them into a network. The references you give for each data point are identified and get a 'sci' tag if they are from a known scientific publisher. The rating mechanism allows the public to score each data point. Uses the Django deployment on AWS featured in this portfolio.

Education and project management platform
Python Django Bootstrap AWS Docker docker-compose EC2

This is a personal project of mine. I created this platform to absorb volunteers willing to work on a humanitarian cause. From the start it was a very complex platform that encompass explaining what the initiative is all about, an education platform and a project management system. Completely build from scratch, I coded all the frontend and most of the core backend, eventually needing help to finish some of the more complex functionalities since it was my first Django project.

Research on recyclable materials
Recycling

This was a proof of concept for IDETRA as we wanted to show that is possible to gather wasted materials and use them to produce water, food, fertilizer, electric energy, and heat. The only non-recycled components of the project were the solar panels, but it is know that they are being found intact in recycling centres. Check out the videos showcasing the final products on the link below.

Recycling used notebook batteries
Recycling Li-ion 3D design 3D printing

After consulting a dear physicist friend about the intricacies of li-ion cell recycling, I was able to design and build a new battery for my eBike using notebook batteries that were going to waste, a laser cutting table and 3D printed parts. For my surprise this new battery was more efficient and had better charge than the old one, increasing the mileage I could travel and making the bike much faster.

The 3-in-1 bench tool
Recycling 3D design 3D printing Arduino

This project started as a simple way to reroute a PC ATX power source to a modular bench power source. The idea of using an ATX power source was due to them being discarded while working just a little underperformed. Later I decided to insert a li-ion cell tester and charger, with the case being a modified 3D open source model from Thingverse.
