This is a mission-driven project, personally funded, and we are moving thoughtfully and carefully — one working milestone at a time. We are building AI custom sites for Non-profit companies. As a result, initially, we are on a budget until we get proof of concept so grant money can be approved for longer term. We have 40 years in AI experience and programming in house. We are a large value driven VAR working with over 1000 clients in the US. Who I'm Looking For: Someone with ERP Experience with Order Entry, Quote Forms, Purchase Order, and Inventory Transactions. Programming in Visual Studio, using Blazor Forms, C#, Radzen, and SQL Stored Procedures. Full Stack Developer. This is because much of our platform will be looking at accounting data for AI to analyze. Being in business for 45 years we have much of the code written but need to expand and add new features. We currently are using components from Radzen. Ability to work with Visual Studio, Visual Code. We have 50 percent of the AI Chat Bot written. Mostly this is about forming SQL tables with memories, chat history, and other data. You should have some knowledge with Agents. We already have the connections on our chatbot to a local LLM which we are training using vectoring and advanced learning. We have API connections to Open Chat GPT. We are working on connections to Watson, and Grok. You need to know how to work with MS SQL Express and create tables. You should feel comfortable working with API, even if in a teaching environment. Most of the technology is changing so your ability to learn and grasp new ideas is the main feature we need, and of course be a good logical thinking person who can understand how objects work and put them together in working logical format Are you located in Massachusetts (Greater Boston, MetroWest, Worcester County, or similar). You’re comfortable sitting initially in our offices to work alongside other developers. Most employees are working local not remote. Working remote is possible with scrutiny. Some of the meetings take place in Norwood, MA, but mostly in Newton, MA In addition you will help with: Azure cloud services (VM setup, storage) Basic server/web app configuration (Linux or Windows Server) OpenAI API (chatbots, calling models) Building a Blazor Form with secure SQL Database, operating with Open Chat AI. You’re willing to learn on the job if needed — but you must already know how to get a basic OpenAI connection working. The First Project Milestone: Set up a secure Azure server Create a simple webpage. Upload a PDF (store it for future AI use) Create simple memory notes (simulated database entries) Connect the site to OpenAI (for basic chatbot testing) Authenticate with Open AI in Linux, close all ports, setup server and AI Send a prompt to Open AI Receive and Display the Answer from Open AI Write a Pytorch add-on to add pdf files to AI Model Add a text box for adding to memories of AI Model Create the database (MDB) or other, for storing this data, secure and encrypted. Test functionality and confirm uploads and chat work Target: About 20–40 hours total. (Work over a few days or spread out over a week — flexible.) If it’s a good fit, we may add: Login system Memory storage tied to user accounts Expanded AI learning features We currently have a version available and in use. You will be working with existing code and on a team with others. Ideal For: People looking for real-world AI project experience Anyone who believes in using technology to make a difference A short intro (who you are, where you live) Any relevant experience (even school projects are fine this technology is new) Your availability (weekdays/weekends) Your hourly rate expectation Important: Please identify your location.
