Allan Jensen
Freelance Software Developer & ConsultantI am a full-stack developer with 19 years of rich experience, building anything from presentation websites to complex online software solutions. I love handcrafting new systems from the ground up, using up-to-date tools that aids in rapid development. I focus on building quality solutions - no dirty tricks and cutting corners. In a world where everything changes quickly it's important to be flexible and prepared for future requirement changes. Planning and proper structuring is extremely important for a successful system. User interfaces must also be carefully designed with the end-user in mind - something that is not a given for a programmer's mindset.
In addition, a company is very likely to have existing systems already running and it is essential to integrate new systems to these as far as possible - otherwise more efficient daily routines are not achieved. I basically only work with components where I have full access to the source code, providing the best opportunities for needed customizations. It is very often the small details that brings a website up to the desired quality for efficient workflows.
Besides programming I also have experience with server management, particularly the entire Linux environment - from initial setup and configuration to maintenance and backup.
I have a passion for my work and enjoy it every single day. I believe in honesty and integrity. You will always be given a fair price offer for any endeavours. God is my partner in business - has been blessed to never needed to look for work - all projects have come about by word of mouth.
