How to Create RESTful Web Services Using Spring and Java with MongoDB as Data Store
...revolve around an African American couple, and I need a seasoned comedy writer to bring them to life. The tone is decidedly comedic—smart, playful, and relatable—while still feeling authentic to Black culture and everyday experiences. The heart of each piece should beat with three recurring themes: family life, cultural traditions, and the ups-and-downs of relationship dynamics. I want the humor to spring naturally from these areas, whether that’s a lighthearted clash over grandma’s secret recipe, a hilarious misunderstanding rooted in cultural customs, or the couple navigating the quirks of married life with quick banter and plenty of heart. What you’ll deliver • A set of punchy, polished skits written in standard script format (dialogue, s...

I need the backend of our new payment platform built first. The immediate goal is a Spring-based microservice (or small set of services) that processes bank-transfer payments end-to-end. Please design the services around clear REST endpoints, document them with Swagger / OpenAPI, and make sure responses are clean JSON (XML only if a partner specifically requires it). Key points you’ll work on: • Spring Boot, Spring Cloud, Spring Security where appropriate • Bank-transfer payment flow: create transaction, verify funds, confirm settlement, emit events • Kafka or another reliable MQ for event propagation • Container-ready code: craft Dockerfiles, helm charts or Kubernetes manifests so I can deploy straight to our cluster • ...

...that I want brought to life for desktop 3-D printing in plastic. The body needs to assemble with simple clip-on / clip-off connections and house a spring-loaded 1.33-inch ball that ejects smoothly and locks back in place. The clip system must balance strength and durability with easy, one-hand operation, and I still want the finished piece to look clean and attractive when it sits on a desk. Because the pen will ultimately be printed in plastic, please work within common FDM constraints—wall thickness, draft angles, and tolerances that keep post-processing to a minimum. What I need from you: • A complete CAD model of the pen and its internal spring chamber, dimensioned for a standard 1.33" ball. • Print-ready STL files plus a STEP (or similar) ma...

I’m ready to launch a full-scale food delivery platform built with React on the front end, Spring Boot for the API layer, and MySQL underneath. The site must feel fast and intuitive on phones, tablets, and desktops, so thoughtful responsive design is essential. Core workflow • Customers browse restaurant menus, search or filter dishes, add items to a cart, then place and pay for an order in a few clicks. • Restaurant Owners have their own portal to update menus, prices, photos, and track incoming orders in real time. • An internal admin dashboard will let me supervise every restaurant, user, and transaction from one place.

...is reached. All sensing and electronics stay inside the handle; the tip itself is a slim passive pin. This is a proof-of-concept prototype, not a finished product. Priority is a fast, cheap, working demonstration. ## How it works (concept) - A thin, rigid probing tip is mounted on a shaft. - The shaft is free to slide a tiny amount (roughly 0.1–0.3 mm) inside the handle against a light preload spring. - Pressing the tip transfers axial force to a force sensor housed in the handle. - The electronics read the force, show it live, and trigger feedback (light + vibration) when a configurable target force is reached. - Force readings are also sent wirelessly (Bluetooth) to a phone/tablet or PC. The key design rule: **the part that touches the surface stays thin and passive; a...
I have a Java application split into two Spring Boot services: • a web-based backend that exposes REST APIs over MongoDB • a standalone CLI client that consumes those endpoints I need thorough functional testing focused on the API layer. Using Postman against the backend (and the CLI where it helps reproduce flows), please verify that every call involved in data retrieval, data updates, authentication and authorisation behaves exactly as documented. Response payloads, status codes, and headers must align with spec, and any deviation or edge-case failure should be captured. Your final hand-over will be: 1. An organised Postman collection with all test cases and environment variables. 2. A concise report detailing steps, actual vs. expected resul...

...Thirds lenses on a “Mission 1 Pro” filter mount, so I need a precise 3D model of a manual-focus lens adapter. The model has to reproduce the exact MFT bayonet on the lens side and the Mission 1 mount on the camera side, with the correct flange-to-flange distance so the lenses hit infinity focus without shims. Along with mechanical accuracy, the model should include a positive-locking mechanism (spring tab or similar) for the lens side, a snug light-tight fit to the Mission 1 body and internal matte baffles to minimise reflections. I plan to prototype on an FDM or resin printer, then machine the final part from aluminium, so please keep overhangs and wall thicknesses additive-manufacturing friendly while still convertible to CNC.

...Creator 4. The look should be unmistakably stylized rather than photoreal, yet still powerful and heroic. All visual elements matter equally to me—facial features and expressive morphs, a well-defined simian-human musculature, plus clothing, jewellery, tail and gada that feel faithful to the lore while fitting the stylised direction. Please keep the CC4 topology clean so I can tweak textures or add spring effects later if needed. Animation is required: a basic locomotion set (idle, walk, run), a handful of combat actions, and at least one signature special-ability move (for example, a mighty leap or a size-changing pose). These can be delivered as separate Motion files or embedded in the iAvatar; just ensure they play correctly inside iClone 8 without additional retargeti...
I have several existing gas-spring CAD files that need a straightforward update: add an external thread feature where specified, then supply clean, professional images of the associated hardware. First, I’ll give you the native CAD models (STEP/SolidWorks format). Your job is to introduce the required external thread on the designated ends of each spring, keeping all other dimensions intact. Once the models are updated, I need high-resolution renders for: • the revised gas springs, • their standard mounts (fixings), • the connecting hoses and fittings.

I have invented a new automatic hose management system for Class 8 semi trucks. This is not simply a hose reel. The invention stores and automatically retracts two standard rubber air hoses inside a durable polymer enclosure that sits on the tractor catwalk. The product must: Automatically retract hose slack using an internal spring system. Allow unrestricted hose extension during trailer turns and coupling. Keep both hoses fully enclosed and protected. Use continuous air flow through rotary swivel fittings. Minimize friction and hose wear. Include a low-friction hose exit guide using rollers or another engineered solution. Be compatible with existing rubber glad-hand air hoses. Sit on the catwalk instead of hanging from the back of the cab. I already have concept sketches and re...
...with strong 3D art skills to build a stylized, artistic 3D visualization of a geothermal hot spring/geyser, based on the reference image attached to this post. The reference shows a hot spring with a deep blue core fading through teal, green, yellow, orange, and red toward its outer rim, with steam rising off the surface and mineral-crusted ground around it. We do **not** want a literal photographic replica — we want an artistic, stylized, real-time 3D interpretation that will run as a custom layer inside a Mapbox GL JS map, geographically anchored to a specific location. ## Scope of Work - Concept and color study based on the attached reference image - Model, texture, and light a stylized 3D hot spring/geyser scene in - Animated steam/vapor effect (shader-...
