Hallo and Namaste from AVDEVS solutions.
Hope the weather back in Munich is good. I see you have posted this requirement for an onsite developer. It is less likely you will get the desired resource here (sure you may be trying with other means as well).
Only if it helps, I would like to offer you the remote location option where the developer works from our office. Some key benefits and considerations according to your requirement.
1. We have German speaking project manager in Switzerland (in case required to drive the project)
2. Offshore development team with single point of contact (English speaking, India)
3. Working with many Swiss clients with remote location approach (References available on request)
4. We are Web development company and not an individual (15 developers and growing)
5. Multiple technologies support (PHP, Zend, Laravel, Symphony, Phalcon, Angular.js, node.js, bootstrap, Magento, Prestashop, Wordpress and mobile apps iOS and Android)
6. Work Agile with collaboration tools from Atlassian (Jira agile, Bit bucket, Hip Chat, Tempo time sheets)
7. Modern office that allows developers room for creativity and productivity (Team and office pictures can be shared).
8. Scale up the team (Add more developers if required)
9. Source code always belongs to you
contact me back and can discuss more on this approach. I can demonstrate how we work with other Eurpoean clients and provide them with high quality code at lower costs.
Best regards
Manan
