Hello everyone,
My name is Jônatas, and I have been a Clarion developer for 27 years, with a solid background in the development and maintenance of enterprise systems in Brazil. I have also worked at Clarion Brasil, the official Clarion representative in the country, which gave me deep technical and market experience with the platform.
Throughout my career, I have developed and maintained multiple projects using Clarion 5.5 / Clarion 6.3 and SQL Server, mainly focused on ERP systems, transportation/logistics systems, and pharmaceutical distributors, always complying with Brazilian fiscal, tax, and legal requirements (NF-e, CT-e, SPED, among others).
In addition to Clarion, I also work as a .NET developer. In 2016, I developed a C# utility DLL to address limitations in Clarion that cannot be easily solved without templates, enabling better integrations, performance improvements, and more flexible architectures for legacy systems.
I am sharing my Clarion experience because I am currently available for freelance and temporary work, including:
- Maintenance and enhancement of legacy Clarion systems
- Critical bug fixes and technical support
- API, DLL, and external service integrations
- Gradual modernization of Clarion applications
- On-demand technical support for internal development teams
If you are looking for someone with hands-on experience, strong business understanding, and deep knowledge of the Clarion ecosystem, feel free to reach out.
