uild AI-Powered Journalist Verification Platform | 60-Day Sprint | Claude Code ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ABOUT US Knowledge Networks is a global AI education and policy organization working with UNESCO, the ITU, and leading journalism schools worldwide. We're building a flagship AI-powered SaaS platform for journalists, newsrooms, and media organizations. This is not a vague idea. We have a 100+ page Statement of Work, detailed functional requirements, technical architecture specs, wireframes, and a clear 60-day delivery plan. You're executing a fully scoped product. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT WE'RE BUILDING A web-based SaaS platform with two interaction modes: (1) a conversational AI assistant (chatbot) powered by LLM integration where journalists upload media, ask verification questions, and receive intelligence briefs in natural language; and (2) structured dashboards for monitoring, team management, and analytics. THE SIX MODULES: 1. Media Authenticity Detector — Video/audio/image deepfake detection via 3+ third-party detection APIs. Visual heatmaps, confidence scores, plain-language editorial summaries. 2. AI-Generated Text Analyzer — Detects AI-written vs. human text via detection APIs + custom stylometric analysis. Accepts paste, file upload, URL input. 3. Source Credibility Engine — Searchable database (10,000+ outlets, 2,000+ profiles) with proprietary 5-dimension credibility scoring. Natural language queries. 4. Disinformation Monitor — Real-time narrative surveillance across X/Twitter, YouTube, Reddit, Telegram, RSS. NLP clustering, propagation mapping, configurable alerts. 5. Investigative Intelligence — Upload document sets (500 pages) for entity extraction, timeline generation, and connection mapping. 6. Community Intelligence — Crowdsourced expert layer where verified users contribute source assessments with peer validation and reputation scoring. PLUS: Auth (OAuth 2.0, SSO), 5-tier Stripe billing, RESTful API with OpenAPI docs, WordPress CMS plugin, admin panel, dark mode, WCAG 2.1 AA accessibility. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ TECH STACK • Frontend: React/[login to view URL] + TypeScript, Tailwind, WebSocket • Backend: Node.js or Python (FastAPI), event-driven async, message queue • AI/LLM: LangChain, Claude API (primary), GPT-4 (fallback), third-party detection APIs • Database: PostgreSQL, Redis, Elasticsearch, Vector DB (Pinecone/Weaviate) • Infra: Docker/Kubernetes, AWS or GCP, Terraform, GitHub Actions CI/CD • Security: OWASP Top 10, TLS 1.3, AES-256, zero-retention processing, pen test before launch • Performance: Page load ≤2s, detection ≤60s video / 30s audio / 10s text, 99.5% uptime ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 60-DAY SPRINT TIMELINE Phase 1 — Core MVP (Days 1–25): Architecture, CI/CD, auth, chatbot, Modules 1–3, scoring engine, billing. UAT with real journalists. Phase 2 — Full Build (Days 26–45): Modules 4–6, API layer, CMS plugin, enterprise features, security audit. Phase 3 — Launch (Days 46–60): Production deployment, stabilization, knowledge transfer, documentation. 90-day warranty begins. Quality Gates at Day 25 and Day 45 with formal acceptance criteria. Dedicated Product Owner (25+ hrs/week) and 10–30 journalists for UAT. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ CLAUDE CODE: OUR PREFERRED APPROACH We strongly encourage Claude Code as the primary development accelerator. Developers proficient with Claude Code deliver 2–3x output vs. traditional workflows. Feed our SOW into Claude Code to generate database schemas, API routes, auth flows, and module scaffolding in hours. API integrations, test generation (≥80% coverage required), and documentation are all dramatically faster with Claude Code. If you're skilled with Claude Code, you can price more competitively. Tell us about your Claude Code experience in your proposal. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT WE PROVIDE • 100+ page SOW with every requirement numbered and prioritized • Architecture spec, wireframes, brand design system • All API keys (LLM providers, detection APIs, Stripe) • Product Owner (25+ hrs/week), 10–30 journalists for UAT • Cloud accounts (AWS/GCP) and GitHub org provisioned • Daily standups, sprint demos every 5 days ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ YOUR PROPOSAL — INCLUDE THESE 8 ITEMS: 1. Your Approach (1–2 pages) — How would you architect this? What's your 60-day strategy? 2. Claude Code Proficiency — Specific examples of AI-assisted development in your workflow. 3. Relevant Experience — 2–3 comparable projects (SaaS, AI/ML, chatbots). Links preferred. 4. Team Composition — Solo + Claude Code, or team of 2–4? Named individuals. Full-time only. 5. Fixed-Price Estimate — Total + breakdown by phase. Hourly proposals must include NTE ceiling. 6. Top 3 Risks — And how you'd mitigate them. This reveals real experience. 7. Availability — Earliest start date. Confirm 60 consecutive days full-time. Non-negotiable. 8. One Smart Question — Ask us one technical question. Shows how you think. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HOW TO APPLY • Start your proposal with "I've read the full brief" — we filter on this. • Maximum 5 pages. No generic templates. • Shortlisted → 30-min video call → NDA → full SOW access → final quote. • All IP owned exclusively by Knowledge Networks Inc. NDA + IP assignment required. THE RIGHT CANDIDATE: Senior full-stack dev (or lean team of 2–4) who's built production SaaS with AI integration. Fluent in React/[login to view URL] + Node.js/Python. Uses Claude Code daily as a core productivity multiplier. Ships under aggressive timelines. Communicates clearly. Knows when to ask questions.

Hi Sanjay P., This is quite similar to a project I delivered last week, so I can jump straight into execution. Ready to start immediately. I've read the full brief Questions: 1) For Media Authenticity, should we ensemble 3+ detectors and calibrate a single confidence (Platt/Isotonic) against your ground-truth set, or present raw vendor scores with a meta-summary? 2) For Source Credibility/stylometry, should features/weights be versioned and editable in admin, and what is the refresh cadence + provenance pipeline for the 10k outlets/2k profiles? Suggestions: 1) Event-driven architecture (FastAPI + Redis Streams/Celery, per-module queues) with idempotent jobs, retries, and circuit breakers to isolate flaky APIs and meet latency SLOs. 2) Strict zero-retention: S3 pre-signed URLs, transient buckets with lifecycle rules, KMS, PII scrubbing, hash-based dedupe; plus model/ensemble versioning and offline eval dashboards with OpenTelemetry tracing. Action Plan: - Days 1–7: Terraform + K8s, GitHub Actions; Auth/SSO; base schemas; OpenAPI; Claude Code to scaffold routes, workers, tests (≥80%). - Days 8–25: Chatbot (Claude primary, GPT-4 fallback, streaming), Modules 1–3, ensemble calibration, Stripe, analytics; UAT. - Days 26–45: Modules 4–6 (elastic ingestion, NLP clustering, graph), public REST/SDK, WP plugin, WCAG AA; pen test. - Days 46–60: Hardening, autoscaling/HPA, alerts/SLOs, runbooks, docs, knowledge transfer; launch and warranty. Best Regards, Sid

Hi, I’ve read the full brief and this is exactly the kind of high-impact AI SaaS system I like building. I’ve worked on full-stack platforms with LLM integrations, real-time pipelines, and modular architectures using React, FastAPI/Node, and vector databases. I’m comfortable handling multi-module systems like yours—from chatbot interfaces to analytics dashboards and API-heavy backends. My approach would be to follow your 60-day plan closely: Phase 1: set up core architecture, auth, chatbot, and Modules 1–3 with clean APIs Phase 2: expand into monitoring, intelligence modules, and integrations Phase 3: optimize, deploy, and stabilize with strong testing + CI/CD I actively use AI-assisted development workflows (Claude/GPT) to accelerate scaffolding, API generation, and test coverage—this helps move fast without sacrificing quality. I can work full-time for the full 60 days and communicate clearly through daily updates and demos. I’ve built similar AI-driven systems (chat + data processing + scoring engines), so I understand both speed and production standards. I would be happy to share relevant work and discuss architecture in detail. Regards, Sergio

Hello, How are you? I am very happy to bid on this interesting project. Also I am glad to inform you that I have relevant strong experience in full-stack SaaS development, AI integration, and chatbot deployment, and have worked on many similar projects before. My approach for your 60-day sprint involves a phased strategy, starting with robust architecture design, setting up CI/CD pipelines, and core authentication (Days 1-25), followed by the incremental development of Modules 1-3, scoring engines, and billing features. The second phase (Days 26-45) will focus on constructing Modules 4-6, API layers, and enterprise-grade security features. Finally, during Days 46-60, I will concentrate on deployment, stabilization, documentation, and knowledge transfer. I am proficient with Claude Code, having used it extensively to generate schemas, API routes, and automate testing workflows, increasing my productivity by 2-3x. Some relevant projects include an AI-powered news fact-checker SaaS, an real-time disinformation monitor, and a multimedia authenticity detection platform. I work with a dedicated team of 3 full-time developers experienced in React, Node.js, Python, and AI tools, ensuring comprehensive coverage from front-end design to backend architecture. My fixed-price estimate for the entire project is $150,000, broken down into phases aligned with delivery milestones. The top three risks I foresee are API integration delays, data security challenges, and tight timelines, all miti
