We are preparing to build a Data Center Construction Intelligence Platform. Before development begins, we need an initial, authoritative dataset covering previously built and currently active data center construction projects in the U.S. This dataset will be the foundation of a platform that is designed to update monthly over time. This role is research and data structuring only — no application development, no scraping tools, and no automation required. Data Sources (Representative, Not Exhaustive) Research should be based on reputable industry sources, such as: BuilderConnected Dodge Construction Network CRANE Construction Intelligence Public owner / developer disclosures Industry reports and trade publications Publicly available permitting and project announcements ⚠️ Important: You are not required to have paid access to all platforms. We are looking for structured summaries and metadata, not proprietary dumps. Scope of Work 1️⃣ Data Center Project Inventory Compile structured information on: Previously built data centers Currently active / under-construction data centers Where available, capture: Location (city, state) Project status (completed / active) Facility type (enterprise, hyperscale, colocation, edge, etc.) Approximate scale (high-level) General delivery model (design-build, CM, etc.) 2️⃣ Construction Systems & Assemblies (Project-Informed) Using real-world project data, organize: Structural systems Electrical & power infrastructure Mechanical / cooling strategies Fire protection approaches Low-voltage & networking considerations Focus on patterns and common approaches, not engineering drawings. 3️⃣ Tier-Level & Redundancy Context (High Level) Where identifiable, note: Tier I–IV alignment (if stated or implied) Redundancy concepts (N, N+1, 2N, etc.) How redundancy impacts construction scope This should remain descriptive, not technical design. 4️⃣ Cost & Schedule Drivers (Qualitative) Based on project patterns, identify: Primary cost drivers Schedule risk factors Regional labor/material sensitivity Supply chain and lead-time influences No exact pricing required. 5️⃣ Structured, App-Ready Data Format (Critical) All information must be delivered in structured spreadsheet format, with clearly defined columns such as: project_name location project_status facility_type system_category assembly_or_component tier_or_redundancy_level primary_cost_drivers schedule_risk_factors data_source notes This dataset will later feed an application and AI system. Deliverables You must provide: Google Sheets or Excel file(s) Clean, consistent structure and naming CSV export Short summary document explaining: Data sources used Assumptions and limitations Recommendations for monthly updates No PDFs. No slide decks. No scraped raw dumps. Ongoing Monthly Updates (Future Work) After the initial dataset is delivered, we plan to: Update the dataset monthly Add newly announced or completed projects Refine patterns as the dataset grows Please indicate in your proposal: Whether you are open to a monthly update engagement Your estimated monthly fee range for ongoing updates Ideal Candidate Experience with construction, infrastructure, or industrial research Familiarity with construction intelligence platforms or trade data Strong data organization skills Methodical, detail-oriented approach Comfortable citing and tracking data sources Screening Question (Required) How would you gather and structure authoritative construction project data so it can be updated monthly and later used in an application or AI system? Generic responses will not be considered.Selection Criteria We will prioritize candidates who: Demonstrate structured thinking Understand construction project data Respect data-source boundaries and licensing Clearly explain how they will organize and maintain the dataset

Unreal Engine + Pixel Streaming + Full Platform Integration

We are a technical team and we handle all technical solutions and decisions ourselves. We are not looking for an architect, a planner, or someone else to define the system for us. What we need is an execution-focused engineer who can help implement the website strictly according to our requirements. This project has very strict verification requirements. There are eight platform development contracts based on the same principle; this is just the first one. We need to deliver a multi-role platform based on (state-machine driven + Stripe payments/escrow + ad bidding + 3D digital humans via pixel streaming).Using low-code + modular composition, we are building an international platform. It must be explicitly stated that this is not an MVP. A.Deployment & Infrastructure(Must be assembled and built on the Fly.io platform) 1) The platform must run on (frontend/backend, jobs/queues, WebSocket/WebRTC services as needed). 2) Proper logging/monitoring/alerting is required, including alerts for third-party integration failures and cost/usage anomalies. B.Core Requirements (Important) 1) Multi-role / four portals: end users, service providers, maintenance staff, and admin portal (different permissions and flows). 2) Critical business flows must be implemented using a state machine / state-driven architecture (no “skipping steps”): order → payment → escrow/split → fulfillment → acceptance → settlement → refund/dispute, with full traceability, rollback rules, and audit logs. 3) Payments: Stripe (payments, payouts, webhooks). Must handle idempotency, webhook replay protection, and concurrency-safe state transitions. 4) Automation / orchestration: n8n (or similar) as the workflow hub, connecting Supabase, payments, notifications, ads, and digital humans. 5) Conversational guidance: use Botpress (or similar tools) for conversations + next-step actions. 6) Advertising: creative management + delivery configuration + analytics; ad slot bidding/auction (e.g., Prebid.js / RTB model). Bidding logs must be retained and auditable. 7) Multilingual: UI/content must support multiple languages and integrate language detection and translation APIs. 8) External widgets / external entry systems：iframe / JS SDK / external components with controlled internal core logic. 9) Risk control mechanisms: rate limiting, switches, circuit breakers, fast shutdown without impacting payments) 10) 3D digital human system (Unreal Engine Pixel Streaming): 10.1.) MetaHuman + Unreal Engine for creating 3D digital humans. 10.2.) Pixel Streaming (WebRTC) to stream UE video to web/mobile clients. 10.3.) A unified control interface to switch avatars/actions and drive lip-sync via TTS audio, integrated with state-machine-driven guidance flows. C.Execution responsibility (mandatory) 1) This project must be completed independently by you personally. We do NOT accept teams, outsourcing, temporary staffing, or task splitting. 2) This requirement exists purely for commercial confidentiality reasons. 3) If the project cannot be completed by one individual, please do not proceed. D. Price and maintenance terms (fixed) Project delivery price: USD 3,000 (fixed) Post-launch maintenance: - USD 100 per month (fixed) - Includes system stability, critical bug fixes, security updates, and environment handling - No unilateral price increase is allowed - Any adjustment requires written mutual agreement If your pricing expectation is significantly higher, or if you cannot accept these terms, please do not contact us. E.Delivery time: 1) For an experienced and skilled engineer, under normal circumstances, the full project should be achievable within two months. 2) In addition, we have a clear requirement that within an earlier phase of the timeline, a runnable pilot version must be delivered. This pilot version is not the final completion, but it must already be in a stable, operable state and able to enter trial operation. 3) During the trial operation, we will identify issues, validate stability, and make necessary adjustments, so that the final delivery can meet the required quality standards. F. Please reply with: 1) Similar projects you have delivered (if possible, provide links/demos). 2) Recommended architecture and service decomposition. 3) What materials you need from me to proceed (execution step flows, required module list, etc.). 4)phased timeline, rough price range.
