Subject: Senior Full-Stack Mobile Engineer for Luxury Multi-Language Ride-Hailing Platform (Flutter / React Native) Hi Developers I’m launching a high-end private ride-hailing service tailored for a specific regional market, and I’m looking for an elite mobile developer to bring it to life. I’m not interested in a messy prototype or a generic, clunky template. The vision is to build something that feels genuinely world-class—fluid, visually stunning, and as effortless to use as Uber, but with a sharper, more refined aesthetic. The interface needs to be clean, intuitive for everyday users, and completely frictionless from the moment someone opens the app to when they complete a ride. What We Are Building: The Passenger Experience: A gorgeous, minimalist UI ...
I’m ready to commission a small, playable prototype in Roblox Studio that teaches kids one essential skill: how to report unsafe or predatory behavior online. The working title is “SAFEGUARD — Think.

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 w...

...development team to build a new professional version of our 12NM platform for iOS, Android and Web. 12NM already exists as a working PWA prototype. It was created quickly and in a simplified way because the first version was developed by someone without professional programming experience. Because of this, the current version has many limitations, bugs, performance problems and things that are difficult or impossible to change. We do NOT want to simply convert the current PWA into a mobile application. We want to build a new and much better 12NM platform based on the existing concept, features and experience we already have. The current PWA is only a reference/prototype. It does not have to be copied 1:1. We are open to completely redesigning the UI/UX, architecture and in...
I’m moving an ibuprofen product from concept to lab-scale prototype and need a formulation scientist who lives and breathes NSAID development. The focus is squarely on formulation and development: selecting excipients, defining the manufacturing process, and generating the data package that will let me progress toward pilot scale without re-work. Where we are now • Target product profile is sketched but flexible; I’m weighing options such as extended-release pellets, solubility-enhanced tablets, or a child-friendly suspension. • No wet-lab work has started; I’m looking for a solid formulation roadmap, prototype composition, and supporting rationale before booking bench time.
