I am looking for a UI/UX designer for ongoing part time work on a mobile app that is already live on Android and iOS. It has real users, so this is design for a product in use, not a concept from scratch. You would design in Figma and hand off to our in-house Flutter developers. You are not writing code, but you will be coordinating closely with them, so designs need to be clear enough that handoff is smooth and questions are rare. This is a long term engagement. I want someone who stays with the product for months and gets to know it, not one quick project. Schedule: this role runs in the evening. I need availability roughly 7 pm to 11 or 12 pm, IST, most working days. Total commitment is 10 to 15 hours a week. What we are looking for: 1. Mandatory: • Strong, conversational Eng...

I need a small working prototype of a water-responsive anti-slip surface for outdoor stairs, ramps, and walkways. This surface should remain smooth when dry, but develop raised ridges/textures to increase grip when wet, returning to flat as it dries. I am based in Ghaziabad, Uttar Pradesh, so I am specifically looking for a freelancer based in or around Ghaziabad/Delhi-NCR who can work with me on the physical prototype. Key Requirements: - Water responsiveness - Flexibility - Wet grip - Recovery after drying Ideal Skills and Experience: - Material science expertise - Experience with adaptive or responsive surfaces - Prototyping skills - Knowledge of anti-slip technologies

I have a steady pipeline of mechanical projects and need a reliable engineer I can turn to on an ongoing basis. The workload ranges from early-stage concept sketches all the way through detailed CAD models, analysis, prototype tweaks and production documentation. Some weeks may focus on refining a single component; other times you might help optimise an entire assembly or advise on manufacturability and cost. Solid proficiency in mainstream CAD packages (SolidWorks, Inventor, or similar) is essential, and the ability to back up designs with sound calculations or simulation results will make collaboration smoother. Clear communication and prompt iteration are just as important as technical skill, since most projects move quickly and I often need fast turnarounds or minor revisions within a...

### What this is I have three KiCad 10 boards for a telecom cabinet monitoring and access-control product. Schematic capture, part selection, footprints, placement, design rules, BOM and fabrication output are all finished. One board is fully routed. The other two have a short list of connections that two autorouters could not place, and I need an experienced layout engineer to close them by hand. This is **not** a "design my PCB" job. It is a well-defined finishing task on a board that is already DRC-clean, with every remaining connection documented and its obstacle identified. ### Current state, measured | Board | Size | Layers | DRC errors | Connections open | |---|---|---|---|---| | Base | 155 × 90 mm | 4 | 0 | 23 | | Cellular module | 80 × 85 mm | 4 | 0 | 0 &...
