We are looking for a senior developer to build a full-stack web application
that incorporates AI features. The project involves creating a user-friendly
platform where users can interact with AI-driven tools to enhance
productivity. The application will support user authentication, data
visualization, and automated content generation through machine learning.
The front end will be built using React with TypeScript, while the back end
will be developed with Node.js and Express, using a PostgreSQL database
for data storage. We will integrate a machine learning model that processes
user inputs and generates relevant suggestions based on the data collected.
The system will also feature an intuitive dashboard that displays analytics
and reports, providing real-time updates for users.
You will be responsible for ensuring smooth integration between the front
end, back end, and the AI model. The application should be scalable and
secure, with a focus on a seamless user experience.
Strong experience with React, Node.js, PostgreSQL, and machine learning
frameworks like TensorFlow or PyTorch is required. Experience with Docker
for containerization and deployment is also preferred.

We are looking for a technically capable freelancer to extract structured parts data from a LinkOne-based offline parts catalog. The catalog is provided as a folder containing its original internal data files (not PDFs).

Objective:
• Analyze the catalog folder and determine how part data is stored
• Extract structured part records including: Part Number, Description, Model and Group reference
• Upload the extracted data to our Supabase PostgreSQL database
What You’ll Receive:
• A complete catalog folder (original file structure)
• Screenshots of file layout (attached to this post)
• Supabase credentials:
• Project URL
• Public API key
• Target table schema

Deliverables:
• A working tool or script (Python preferred) that:
• Parses the catalog folder and extracts usable records
• Uploads data to Supabase
• One-time output (CSV, SQL, or Supabase insert)
• Clear instructions for applying the same process to future catalogs

Important Notes:
• This is not a PDF or XML job - the catalog is based on a legacy LinkOne format
• The file structure may vary - we are open to partial results if full extraction is not feasible
• You must explain limitations or challenges clearly if full data cannot be retrieved

Ideal Experience:
• Experience with legacy or proprietary data structures
• Reverse engineering / data mining
• Python scripting (text/binary parsing, regex, etc.)
• Familiarity with Supabase or Postgres APIs
