Profile: https://flows.cv/frederickengelhardt

As a Software Developer, I love taking on new challenges and collaborating with others on projects. I appreciate the value of self improvement and attribute it to my Software Development career - A continuous cycle of learning, adapting, and creating.

Everyday I am striving to learn and integrate old and new technologies to improve my knowledge and understanding of the current technological world. I love to attend meetups to see what others are doing in the field and find their feedback invaluable.

While I am not coding I enjoy playing my guitar, biking to new places, and going on road trips. I am a AR/VR Advocate and love following releases and trends coming from related fields.
