We need an experienced WebAR / computer vision developer to create a browser-based virtual piercing try-on. Users should open a webpage on iPhone/Android, activate the camera, and see a virtual stud realistically positioned on their ear. The key challenge is reliable ear/eartlobe tracking while the head moves. This is NOT a request to copy existing commercial software. We want an independently developed solution using open-source or approved licensed technology. FIRST MILESTONE – PAID PROOF OF CONCEPT Deliver a working browser demo that: * Uses live mobile camera * Detects/tracks the head and ear * Places a virtual 2–4 mm stud on the earlobe * Keeps the stud reasonably anchored during head movement/rotation * Works on iPhone Safari and Android Chrome Possible stack: MediaPipe, [login to view URL], WebGL, [login to view URL], React, OpenCV, WebAR/WebXR or another recommended approach. If successful, developer may receive the full project including: * Multiple piercing locations * Multiple studs simultaneously * Jewelry/product catalog and SKUs * Ear and future nose visualization * Saved piercing looks * QR/customer-specific links * Multi-tenant customer accounts * Master admin dashboard * Customer activation/suspension * Usage analytics REQUIREMENTS * Strong WebAR/computer vision experience * Client-controlled GitHub/GitLab repository * Client owns all custom source code * All third-party libraries/SDKs must be disclosed * No paid/proprietary dependency without approval * Code must be maintainable by another developer TO APPLY Do NOT send a generic proposal. Please provide: 1. Links/screenshots of relevant AR or computer-vision work 2. Your proposed technology stack 3. Your FIXED price for the initial proof of concept 4. Estimated time to complete the POC 5. Estimated range for the full MVP IMPORTANT SCREENING QUESTION: How would you reliably anchor a virtual stud to the earlobe during head movement when standard facial-landmark systems provide limited detailed ear landmarks? Applications that do not answer this question will not be considered.

Hi, The virtual piercing try-on system involves precise real-time alignment of 3D models on live video feeds, which requires robust computer vision and AR tracking integration. The main technical risk is achieving stable and low-latency rendering on mobile devices while maintaining accurate piercing placement. While my primary experience is in AI-driven backend architectures and document intelligence, I have led complex systems involving real-time data processing and integration of computer vision pipelines, which parallels the challenges in AR tracking and rendering. I typically design systems by separating core components such as tracking, 3D model management, and rendering layers to isolate performance bottlenecks and enable independent scaling and testing. Early validation of tracking accuracy and model alignment will be crucial. To ensure reliability, fallback mechanisms for tracking loss and adaptive quality adjustments can reduce latency spikes and maintain user experience consistency. I can start by outlining the AR pipeline architecture and integration points for 3D model management and tracking calibration. Clifton

Hello, I have already completed similar WebAR and computer vision projects involving mobile camera tracking, facial landmarks, 3D overlays, and browser based AR. I have strong experience in web development, APIs, and scalable software solutions, and I can quickly understand the tracking challenge and deliver a reliable proof of concept. For ear anchoring, I would combine head pose estimation with dedicated ear and earlobe detection, then use temporal smoothing and landmark confidence checks to keep the stud stable during movement and rotation. MediaPipe or another approved vision model can be evaluated during the POC based on accuracy and mobile performance. Would you be able to share your preferred stud model or reference image for the POC? Let’s schedule a quick meeting to discuss the tracking approach and project requirements. I will share my portfolio in chat I look forward to hear from you. Thanks Best Regards, Mughira

Hi, I understand the challenge of persistent ear tracking for WebAR and can build a robust solution for your piercing try-on. **Relevant Experience** I previously engineered a facial liveness detection system using MediaPipe and custom CNNs to track micro-movements, ensuring stability under varying lighting—a core requirement for your ear-anchoring challenge. **Technical Approach** To anchor the stud, I will use MediaPipe Face Mesh to establish a head-pose coordinate system, then implement a secondary lightweight **Landmark Regression model** trained specifically on ear-anatomy keypoints to map the lobe relative to the tragus/helix, maintaining 6DOF stability. **Proof of Concept** * **Price:** €1,200 * **Timeline:** 10 days * **MVP Range:** €5,000–€8,000 **Screening Answer:** I would use a **Procrustes Analysis** on the ear’s geometry to calculate a local coordinate frame, ensuring the stud remains locked to the lobe even when the global facial landmarks shift. Do you have existing 3D assets for the studs, or should the POC prioritize the tracking pipeline first?

I have read your requirement and can turn your approved Figma/Sketch designs into a pixel-perfect React Native frontend for both iOS and Android. I’ll convert each screen into reusable components while matching the exact spacing, typography, colours and responsive behaviour. I’ll also set up clean navigation and a scalable structure with proper state/API placeholders, so your backend team can integrate APIs without changing the UI. For performance, I’ll use modern React Native with functional components and Hooks, optimize images and lists, and implement smooth animations and gestures where required by the design. I’ll test the screens across both platforms and different device sizes to ensure consistent rendering. You’ll receive the complete React Native source, iOS/Android configuration, navigation setup, API-ready structure, build instructions and handover documentation. Please share the Figma/Sketch designs and screen count. I can review them and confirm the timeline before starting. Best Regards Prachi Webix Infotech

Hey, Tom here. I've done real-time mobile tracking with Flutter/Dart and Appwrite, and I've dug into MediaPipe's face mesh for similar alignment problems. For the earlobe anchor, I wouldn't rely solely on facial landmarks—they're too sparse for ears. Instead, I'd use MediaPipe's face geometry to establish a 3D head pose, then detect the ear region as a local feature and refine its position with optical flow or a tiny custom-trained model to keep the stud locked during rotation. Shoot me the answer to your screening question—how hard is head movement, like casual turns or fast shakes? Cheers, Tom.

Hi, I've built browser-based computer-vision demos using WebGL and real-time landmark tracking. You’ll need a WebAR page that uses the live iPhone/Android camera to detect the ear, stabilize a 2-4 mm stud on the earlobe, and keep it anchored during rotation using an open, maintainable pipeline. I can deliver a reliable POC with MediaPipe-style face/ear tracking and OpenCV refinements. Best, Razmik
