Build Three Production-Ready AI SaaS Platforms

HIRING: SENIOR AI FULL-STACK DEVELOPER / SOFTWARE ARCHITECT / DEVELOPMENT TEAM — THREE COMPLETE PRODUCTION-READY SaaS PLATFORMS COMPANY: NEVIE-GLOBAL (France). PROPOSED TOTAL FIXED PRICE: USD $750, subject to written acceptance. CONTRACT: full delivery, verified milestones, long-term technical partnership. We seek an experienced senior engineer or small multidisciplinary team to finish, secure, test, deploy and hand over THREE independent commercial SaaS platforms. NOT prototypes, MVPs, static dashboards, demos or partial deliverables. Existing specifications and code must be audited, verified, corrected and reused when appropriate. Every promised feature requires reproducible evidence and a written acceptance criterion. 1. AI AGENT & AVATAR FACTORY — COMPLETE PRODUCT: Secure multi-tenant SaaS with a target catalogue of 502 DISTINCT, working, documented and individually tested AI agent/avatar references. Consumer packages: 4, 8 or 12 agents, each with one supervisor. Professional packages: 12 agents + 1 supervisor + 1 AI Architect; 24 agents + 3 supervisors + 1 AI Architect; 60 agents + 5 supervisors + 1 AI Architect. Support creation, onboarding, activation, execution, supervision, pausing, versioning, updating and safe shutdown of agents; text, supported voice and visual avatars; model-provider APIs, RAG and document knowledge bases. Business functions: lead generation, prospect scoring, sales assistance, CRM synchronization, email drafting/approved sending, WhatsApp Business, appointment booking, calendars, support/tickets, quotes, invoicing, marketing campaigns, social media content/approved publishing, document workflows, website audits, reporting and industry-specific processes. Commercial functions: bilingual FR/EN public site and catalogue, self-service customer onboarding, organizations, roles, secure authentication, plan selection, checkout, subscription changes, invoices, customer/admin dashboards, usage quotas, metering, cost alerts, payment integration, integration permissions, audit trails, logs, backups, recovery and strict tenant isolation. 2. AI FACTORY BUILDER — COMPLETE INDEPENDENT PRODUCT: Convert a customer’s natural-language request into a genuinely operational AI team. The system must gather missing requirements, analyze business objectives/data/budget, propose an architecture, select or generate authorized agent components, assign tasks, connect central/specialist supervisors and an AI Architect, assemble executable workflows, configure approved CRM/email/calendar/WhatsApp/API connections, estimate usage costs, test the configuration, seek human approval, deploy safely and monitor the resulting team. Include a separate customer portal, organizations, projects, subscriptions, billing, administration, reusable templates, n8n integration, workflow execution, isolated environments for approved code generation, credential handling, permission checks, simulation, functional/integration/security/cost tests, conflict and loop detection, quota controls, observability, logs, alerts, rollback and emergency stop. Acceptance requires the creation, deployment and successful execution of a NEW complete team from an unseen business request, with test evidence—not a generated diagram or mocked workflow. 3. CYBERGUARD AI — COMPLETE DEFENSIVE CYBERSECURITY PRODUCT: Commercial SaaS with 1 AI Architect, 1 central supervisor, 6 specialist agents and extensible security engines. Include public-information non-intrusive checks and separately authorized audits; asset inventory, verified scope/consent, DNS/network/HTTPS/security-header checks, local configurations and patch status, supported USB/Bluetooth/BLE/Wi-Fi inspections, evidence collection, severity and business impact, findings requiring verification, PDF reports, dashboards, historical comparisons, scheduled permitted monitoring, alerts, remediation guidance, approved corrective scripts and customer subscriptions/billing. Mandatory safeguards: target authorization, tenant isolation, authentication, encryption, audit logs, secrets protection, request limits, SSRF/DNS-rebinding protections, manual approval of sensitive actions and no unauthorized intrusion, exploitation, disruptive scanning or data extraction. Deliver functioning Windows, macOS, Linux, Android, iOS and iPadOS applications, respecting each OS’s permissions and technical restrictions. Windows priority: Tauri/Rust desktop app, secure local diagnostic engine, controlled PowerShell, Python/backend connection, install/uninstall and MSI installer. Other OSs: working distributable packages, supported diagnostics, permission/capability matrix, installation instructions and platform-specific tests. Review existing J1–J6.1 work and independently reproduce the 117 previously reported tests; 4. SHARED ENGINEERING STANDARDS: Preferred stack: Python/FastAPI, React/Next.js/TypeScript, Supabase/PostgreSQL, secure REST APIs, row-level security, role-based access, multi-tenant isolation, AI/LLM APIs, RAG, multi-agent orchestration, n8n, Tauri/Rust, Docker, GitHub and CI/CD. Require secure credentials, encryption, auditability, background jobs/queues, error recovery, observability, automated unit/integration/end-to-end/security tests, backups, restore drills, deployment scripts, performance monitoring and FR/EN interfaces. 5. PRICE AND CONTRACT: NEVIE-GLOBAL proposes USD $750 as the TOTAL FIXED DEVELOPMENT PRICE for ALL THREE COMPLETE PRODUCTS, not an hourly fee, audit-only assignment, MVP or first-phase budget. If $750 is not feasible, say so BEFORE any agreement and provide a justified alternative fixed quotation; no higher price, hidden fees, extra subscriptions or reduced deliverables are authorized automatically. Agree milestone amounts and objective acceptance criteria in writing; payments follow verified delivery and written acceptance under the platform’s applicable payment terms. 6. REQUIRED CALENDAR: NOVEMBER 27, 2026 (BLACK FRIDAY): deployable foundations of all three SaaS,
