Hello! My name is George

I help people build scalable and manageable software products.

During my career, I have gained experience working in companies of various sizes and I have grasped various concepts and approaches concerning web development and programming in general. I enjoy being challenged and working on projects that require me to work outside my comfort zone and knowledge base.

I am available for hire on a freelance basis and it would be my pleasure to help you get your projects done.
