Senior Freelance Full‑Stack Developer (TypeScript / Node.js / React / Next.js) – Lead Architect for a 8‑Website Ecosystem (Long‑Term)

Important – Full Ecosystem Scope (8 Websites)

You are not applying for a single standalone marketing site. You are applying to become the technical lead for an integrated ecosystem of 8 interconnected websites, with strong ties to finance, MFOs, private clubs and investors.

The project includes both: Rebuilding existing sites (currently in WordPress), and creating new sites and interfaces on a shared modern architecture.

Project Goal Design and implement a unified technical architecture for 8 ecosystem websites (RWA tokenization, MFO, investor clubs, AI, MCP, etc.).

Gradually move away from a “WordPress everywhere” approach towards: a shared backend in Node.js/TypeScript, and modern frontends in React/Next.js.

Strengthen security, consistency, and prepare for a future central application and mobile apps. Target Stack Backend Node.js + TypeScript (Nest.js or similar).
REST and/or GraphQL APIs.
Authentication, roles/permissions, multi‑site / multi‑tenant.
External integrations: KYC/KYB, fintech, AI, MCP servers, etc.
Web Frontend React + Next.js (SSR/SSG, SEO, multilingual, high performance).
Clean, elegant UX suitable for finance / MFO / investor environments.
WordPress Used on several existing sites .

Your role is to: possibly use WP headless in the short term, and migrate sites to the new architecture over time.

Future Mobile / Apps Architecture must be designed so future mobile apps (e.g. built with React Native) can consume the same backend and APIs.

Global Scope (8 Websites) The selected developer will be responsible for the entire 8‑website ecosystem, including: Full rebuilds for some sites. Modernization / harmonization for others. Creation of new sites / interfaces where needed (new clubs, hubs, portals).

Main Responsibilities
Design the shared backend architecture (Node.js/TypeScript) for the ecosystem.
Rebuild on the new secure stack.
Rebuild / modernize the key sites Set up a clean CI/CD pipeline (staging, production) and deployment best practices.
Lay solid foundations for future web and mobile applications (clean APIs, separation between frontend and business logic).
Document the architecture and key technical decisions.

Required Profile
Must‑have: Senior Full‑Stack TypeScript developer:
Backend: Node.js (Nest.js or similar), APIs, security. Frontend: React + Next.js.
Strong skills in: Authentication, permissions, security (OWASP practices).
External API integrations. Performance, SEO, clean code and maintainable architecture (tests as a plus).

Nice‑to‑have: Solid WordPress experience (for auditing, securing and managing migrations – not to rebuild everything in WP).
Experience managing multi‑site / multi‑brand setups.
Background in finance, fintech, MFOs, investor platforms, or other sensitive environments.
Ability to work autonomously, with a long‑term ownership mindset.
Engagement Long‑term collaboration covering the full ecosystem (8 websites).

Mandatory Confirmation (to be considered) To be considered, you must start your proposal with this exact sentence: "I confirm that my bid is for the full ecosystem (8 websites) and I am prepared to architect and handle the unified platform." Proposals without this exact sentence at the beginning will be ignored automatically. Your bid must reflect your willingness, availability, and capacity to handle the entire 8-website portfolio.

If you are only interested in working on one website or short-term work, do not bid.
