Freelance full stack web developer in Madagascar

A freelance full stack web developer can own the complete delivery path: scoping, interface, API, data, deployment and follow-up. You avoid routing every decision through a sales contact, project manager, front-end team and back-end team.

My main stack is JavaScript and TypeScript: React and Next.js for the interface, Node.js for APIs, PostgreSQL or Supabase for data. That shared foundation keeps types and business rules consistent from end to end. Remote work with European clients is straightforward: I work in French and English from Antananarivo on UTC+3, with several hours of daily overlap.

My indicative day rate is €350. The quote defines scope, deliverables and acceptance criteria before work starts. You can check the expected level in the portfolio, then choose the relevant specialization: React/Next.js, Node.js/API, Supabase or AI agents.

Modern JavaScript front-end relies on React and its framework Next.js, which handle server rendering, SEO and performance. It is the visible part of your product, the one your users touch first.

For a fast marketing site, a SaaS or a dashboard, the specialization to choose is the React / Next.js developer. There you will find the expected skills, static or server rendering, Core Web Vitals optimization and accessibility. Next.js can also serve the front-end and the API from the same project, which simplifies deployment and reduces the technical surface to maintain over time.

The JavaScript back-end is built on Node.js, the runtime that powers the server, REST or GraphQL APIs and asynchronous processing. It is the invisible engine that connects the interface to your data and third party services.

If your need is a robust API, webhooks, authentication or integrations, head to the Node.js developer. Node.js shares the same language as the front-end, which lets you reuse types and business logic across both layers. For applications that combine a database with real time features, the Next.js + Supabase developer stack is often the best trade-off.

JavaScript is now a first class language for applied AI, thanks to the SDKs of the major models and orchestration tools like n8n. This is not about research, but about useful AI wired into your business processes.

To automate a workflow, build an assistant that acts on your tools or enrich a product with reasoning, see the AI agent developer. A well designed agent reads your data, calls your APIs and triggers actions, all integrated into the rest of your JavaScript application. This technical continuity avoids fragile bridges between a business stack and an AI layer kept apart.

The right choice depends on your real need, not on a technical trend. A site or a SaaS points to React and Next.js, an API or a backend to Node.js, an intelligent automation to an AI agent, and a real time application to Next.js plus Supabase.

In practice, most projects combine several of these bricks, and that is the whole point of a single fullstack JavaScript profile. You start on one specialization, then expand without changing language or team. The table below sums up this guidance to help you quickly find the page most useful to your project, before we discuss it together.
