👋 Hi there, I’m a senior software engineer with over +8 years of experience. I can help you write cleaner code, focus on design patterns, and follow best practices to get quality results fast. I particularly enjoy discussing: * TypeScript * JavaScript * Node * React * GraphQL * NextJS, Astro and Gatsby * Twig * CSS/SCSS * WordPress I’ve been praised for going the extra mile and take pride in delivering neat code that is optimized for maximum readability and scalability. I live for the expression of someone who's been struggling with an issue for hours until the solution finally clicks. I'm a big fan of open source and teamwork. That's why I work on open platforms like [Netlify][1] for my side projects and I offer discounted fees for students who are just starting out. My passions, besides programming, are playing the guitar, playing football and training for my next marathon. 💰 Money-back guaranteed: just let me know if you're not happy with the session and your money stays with you.

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.
