Mickael S.

I help SMEs, agencies, and operational teams transform their manual or scattered processes into reliable business systems: internal applications, dashboards, automations, API integrations, and custom back-offices.

I start with the business problem: unstable applications, scattered data, critical Excel sheets, forgotten follow-ups, unconnected tools, impossible tracking, or processes too dependent on a single person.

Since 2019, I have been working on demanding products — connected systems (IoT, dashboards, embedded systems), back-offices, synchronization logic, role/permission management, server security, and SaaS projects.

What I can build:

- React / Node / TypeScript business applications;

- Management dashboards and admin interfaces;

- REST APIs, webhooks, and integrations between tools;

- n8n / Make automations when relevant;

- Stabilization, security (OWASP), and evolution of existing applications.

My approach: automate what can be automated, develop what needs to be developed, and avoid overly complex solutions that impress in demos but collapse in production.

Typical missions:

- create a usable business dashboard;

- replace Excel/email tracking with a web tool;

- connect multiple tools via API;

- stabilize an existing React/Node app;

- set up a maintainable n8n workflow;

- create a scoped internal or SaaS MVP.

Stack: React, Node.js, TypeScript, Python, FastAPI, PostgreSQL/MySQL, Docker, n8n, REST API.

If your needs are unclear, I start with a short diagnosis to clarify the problem, prioritize features, and avoid developing the wrong solution.
