About Simon

Welcome to my profile, my name is Simon and I am a full-stack developer artisan

With 15 years of professional experience in various fields, initially in banking and insurance, I have been involved in maintenance and development.

I have worked on projects with standards, particularly for DSN.
Data in a file, I insert it into a database, display it on screen, and finally generate a report.

Then, for legacy projects, I can develop my skills to become an expert.

This means undergoing a migration, for example to the .NET or Angular framework, to ensure the maintainability and security of the application.

Today, I work on analyzing needs up to the delivery of applications, while respecting the specifications.

Here are my achievements in the first place:
Data reception and unit tests
Creation of websites & landing pages
Responsive design adapted for mobile/tablet
Conversion-oriented pages to generate calls & messages
Custom WordPress development

Features:
• Secure file backup and management
• ERP management & exploitation of raw data up to reporting

Objective: I offer my services, a free audit
-understand the context, what has been thought and done
-scope your project, agree if the means implemented to start the work well, a kick-off
- and define the best technical solutions, obviously I remain attentive to the existing team if there is one and I use best practices.
- not forgetting to agree on regular points or activity reporting and to warn of delays
This is exactly what is happening for my client in the public sector. And today I am in charge of discussing the quote and ensuring client relations.

See you soon, I hope
Simon
