    I already have the electrical trigger sorted—I can close a relay on command—so what I need now is the physical device that releases a single D-cell (originally horizontally oriented), guides it down a short chute, twists its orientation to vertical, and lets it “stick the landing” on its negative end against a small table-mounted magnet. You’ll take the idea from concept to working prototype: • Design a compact, good-looking drop tube. I’m open to either a well-finished plastic print or a machined metal sleeve, as long as the result feels solid and attractive on the bench. • Specify and integrate the solenoid release. A pull-type makes sense, yet if you see advantages in a push configuration that nudges the cell off a ledge,...

    I’m refreshing my online store and need a modern UI/UX that moves visitors smoothly...matters, but only when it serves speed and clarity. Here’s how I’d like to work: • Start with low-fidelity wireframes to lock down flow and hierarchy. • Progress to high-fidelity mock-ups and an interactive prototype in Figma (or Adobe XD if you prefer). • Finish with a concise design system—colour palette, typography, reusable components and states—so my developers can implement the look without guesswork. I’ll provide brand guidelines, product imagery and analytics on current pain points as soon as we kick off. Deliverables are approved screens, the layered design file, and the design system document. If this sounds l...

    ...plus plot constraints (permitted development rules, setbacks, massing) — this is the core differentiated IP of the product, and largely still needs to be built out, not just maintained. - Own uptime, monitoring, and incident response for the calculation engine and Otto during the Glue Dog pilot and beyond. You build the observability stack; you also carry the pager until we can hire under you. - Design and enforce output constraints on the LLM layer consistent with FCA/FSMA compliance requirements (no ROI%/yield/annualised-return framing, RICS development-appraisal terminology only) — the compliance logic is defined; you own making it structurally unbreakable rather than instruction-dependent. - Mentor and technically direct the two existing engineers on infrastructur...

    I need an short evaluation sheet, a 2-page .docx file, filled out by an English speaker in the United states, Singapore or Malaysia. The evaluation is about a small e-learning prototype. While evaluating, please take in mind that the service is not an AAA-quality service, and the video itself is not for evaluation (please evaluate website and UI only)
