TOULOUSE AND REMOTE · FREELANCE DEVELOPMENT
Backend and API developer in Toulouse
A backend that supports your product and connects your tools without adding friction for your team.
I’m Jonathan Corral, a freelance backend developer working with businesses in Toulouse and remote teams. I build business applications, APIs and integrations. My role is to turn an operational need into a system with understandable rules and data flows.
Build the logic behind your product
Your backend manages the data, permissions and rules that make your application work. We identify critical operations and failure cases to define a coherent scope, then build features that can evolve without replacing the whole system.
- Business applications and back-offices
- Business rules, data and access control
- APIs for your interface or partners
Connect tools through APIs
When tools cannot communicate, your team fills the gap with manual entry and exports. An integration can connect a form, CRM or another service to your application. We define the exchanged data, authentication, service limits and error handling before implementing the connector.
Automate while keeping control
Reliable workflows also need to handle interruptions and inconsistent data. Depending on the requirements, we plan useful logs, checks, recovery steps and mechanisms to avoid processing the same operation twice. Tests focus on the workflow’s important rules and risks.
A delivery your team can operate
The scope states what is connected and what remains manual. Code, configuration and handover documentation are prepared for the agreed environment. Third-party service costs and operational constraints are discussed before development starts.
Before we start
How do backend development and API integration differ?
The backend holds your application’s rules and data. An API integration lets it exchange information with an external service. A project can require both.
How can we tell whether a workflow can be automated?
We examine its inputs, rules and exceptions. API availability, data quality and required human approvals determine a realistic scope.
