Hi! I'm Fernando, a professional systems programmer since 1997. I have another 10 years as an amateur programmer, since I started programming when I was 9 years old, or maybe earlier, because my father is also a programmer. I have a Degree in CS. In recent years I have been involved in the Bitcoin and Blockchain development: I'm a member of the Bitcoin Cash developer committee, contributor of Bitcoin-ABC (main BCH implementation) and the lead developer of Bitprim (BTC, BCH and LTC full-node implementation), both nodes are open-source. I'm a tech blogger and public speaker. I love algorithms, data structures, mathematics, computer architecture and low-level computer stuff. If you want to improve your skills in C++, C#, Bitcoin, blockchain, algorithms, system programming or performance optimizations don't hesitate to get in touch.
