Bogota, Colombia · (+57) 321 256 7070 · r@camilo.engineer · rojas@camilo.engineer

Telecommunications engineer. Experience in budgeting for hardware projects, software and hardware development.

Over 4 years of experience as Full Stack developer and over 6 years as Electronic Developer.

Wide experience in programming languages such as C, C++, PHP, JavaScript and Python.

My wide understanding of networking, hardware and software allows me to rapidly infer root causes of issues and failures that arise on complex systems and platforms.

I like to work in multicultural environments and to have the opportunity to meet people around the world.

My hobbies are building drones from scratch, professional 360 photography, 3D printing, and vertical farming.
