Blockchain Developer Needed for Pi-Powered Prediction Market MVP

We are building an MVP for a prediction market platform designed for the Pi Network community. Users will access the platform through the Pi Browser and place predictions using Pi Network’s native coin (Pi). All the actual market logic—creating markets, placing predictions, resolving results—will run on the Polygon blockchain. We will be using UMA Protocol (LongShortPair and Optimistic Oracle) to ensure secure and transparent resolution, but users will never interact directly with Polygon or need MATIC; everything is handled by the backend. We need an experienced blockchain developer to help us complete the MVP by: Deploying UMA contracts on Polygon (testnet first, then mainnet). Connecting the backend so Pi user actions are processed on Polygon automatically. Setting up a secure gas wallet to handle Polygon transaction fees. Running full end-to-end testing with live Pi transactions. Providing basic documentation for future updates. If you have experience with Polygon smart contracts and backend integration, and ideally have worked with UMA Protocol or similar Oracle-based prediction markets, we’d love to hear from you. Estimated Duration: 3–4 weeks Start Date: Immediate Budget: $1,250–$1,500 CAD (milestone-based) Please share your experience, similar projects you’ve worked on, and your estimated cost and timeline.

Snapping polyline Code creator auto cad

I require the development of an AutoCAD plugin to facilitate polyline measurement with labeling. The plugin should enable the user to sequentially select points to create a polyline with horizontal and vertical segments connecting each point. As segments are added, the tool should provide the dimensional measurements of individual segments near their endpoint in a formatted feet/inches labeling scheme (e.g. 10'-5"). Segment endpoints should also be numerically labeled in sequence. Finally, a running total of the polyline length should be dynamically displayed alongside the drawing area. The goal is to expedite dimensional polyline creation and analysis in AutoCAD for layout and construction documentation. AutoCAD experience is essential to program the VBA or .NET based solution to meet drafting workflow needs. An example pictures is attached for what I’m looking for
