I need a mechanical 3-D CAD model built specifically so I can run detailed structural analysis on it later. All geometry must be fully parametric, dimensionally accurate, and organised in a clean feature tree that lends itself to straightforward meshing for FEA. My focus is on the engineering integrity of the design, not on photorealistic rendering, so please keep surfaces simple, remove unnecessary fillets where they do not affect strength, and name every feature sensibly.

What you should bring When you respond, include examples...

...and device-tree overlay edits, all deployed on Debian/Ubuntu images via remote workflows. Day-to-day coding will be done in Python for the high-level hardware control layer, so fluency there is essential; C/C++ knowledge for the lower-level pieces is a plus but not mandatory. You will be working with: • GPIO • I2C • SPI The schedule is flexible—part-time or full-time—and everything is handled remotely. When you apply, focus on your BeagleBone experience: link to relevant GitHub repos, forks, demos, or shipped products that showcase similar work.

I urgently need an experienced mobile app developer to resolve a persistent OTP issue in my application, where the system always sends the phone number with country code (+92) regardless of the user’s actual selection—for example, if someone chooses Iraq (+964) or Kuwait (+965), the app still defaults to +92. The job requires thoroughly checking and correcting the country code picker and phone input logic, ensuring the chosen country code is passed correctly to the backend or API, fixing the OTP sending process for all countries, and testing with multiple international numbers to guarantee proper functionality on both Android and iPhone (where applicable). I’m looking for someone skilled in OTP integrations (Twilio, Firebase, MSG91, WhatsApp API, etc....

...Maven-driven demo that shows how a Wildfly 20 Java servlet can talk to three separate mobile authenticators—Microsoft Authenticator, Google Authenticator and Duo Authenticator—and report back the outcome of each challenge. Scope • Focus exclusively on “second-factor” calls: how the servlet initiates a push / TOTP / Duo prompt (the “sending signal” part) and how it parses the success, timeout or failure response that comes back (“receiving results”). • No UI polish is necessary; a simple JSP or REST endpoint that prints JSON or plain text is fine as long as the code flow is clear. • Keep the sample lean but complete: working source, config files, and any required libraries or REST client snippets. ...

Our property, Mortons at Russell’s Bridge, needs a premium logo that feels as enduring as the land itself. The Morton Bay fig tree is the heart of the design—it’s the most recognisable feature on the farm and must take centre stage. I’d like our livestock (Angus cattle, sheep and Welsh ponies) woven in only if they can be integrated subtly without stealing focus from the tree. The finished mark should work flawlessly in black-and-white; any shading or texture you add has to translate cleanly to single-colour use for signage, embroidery and screen-printed merchandise. Because the logo will appear everywhere—from the gate sign to hats and feed bags—I’ll need fully scalable vector artwork and clear usage guidelines. Deliverables &bul...

1. Project Overview(Backend Microservices System (SPRING FRAMEWORK ONLY)) We are developing a large-scale, enterprise-level digital commerce platform on a Java-based microservices architecture (Spring Ecosystem). The development phase is "LARGELY COMPLETED". We are not looking for a builder to start from scratch, but rather a "finisher"—a skilled Backend Engineer to take ownership of the existing codebase. The primary goal is to validate current integrations, stabilize the logic, and ensure the system is production-ready through rigorous testing. WE WILL PROVIDE TESTING HELP FROM OUR SIDE TOO. 2. Current Project Status & Scope The following microservices have been developed. Your role is to ensure these services communicate seamlessly, h...
