Freelancer profile translated to English.
Back to original languageAbout Manuel
I am happy to offer my many years of experience as a software developer for part-time projects and assignments.
My name is Manuel and I am looking for small assignments and projects of a maximum of 5 hours per week that I can implement remotely.
I have in-depth and many years of development experience with
- Java
- PHP
- SQL (e.g. MySQL/mariaDB), noSQL
- HTML5
- JavaScript, JQuery, JavaScript, CoffeeScript
- XML/XPath/XQuery/XSL-FO/XSLT
Furthermore, programming with Scala and Python is not foreign to me.
I do not offer web design and prefer the development of backend applications and the automation of processes.
In the following areas, I have already developed applications that have proven effective in productive use and can be built upon if necessary:
- Creation of invoices, e.g. from orders in the online shop with invoice email and invoice PDF
- Management of master customer data
- Online portals: Advertisements displayed via a search function on a website. Visitors to the site can post their own advertisements (possibly with images) free of charge; after activation via an activation link, the advertisements go online
- Creation of SEPA XML for SEPA direct debit collection for SEPA mandates
- Generate PDF/Word/Excel/Email files
- Websites with product catalog, detailed search and shopping cart/online shop including backend for accounting/invoicing
- and much more.
I enjoy working with new programming languages and new technologies and am able to quickly gain in-depth knowledge of specific subject areas. I see the best possible synergy effects when the client/employer has requirements where my source code from previous software projects can be reused, as this allows a lot to be achieved in a short time even with a small number of weekly working hours.
