I’m Javier and I specialize in helping both startups and small to medium businesses with high-quality solutions to their electronics engineering challenges. I work hands-on and in-person with my talented team of 7 electronics engineers at “A Blug Thing In The Cloud”. We have a physical laboratory with extensive hardware and software development capabilities that allows us to quickly develop, test and iterate solutions for our clients. If we’re working together, you can expect that your hardware and software is designed properly at the first time and works exceptionally well in its application so that you can focus on the rest of your business. 🎯 📞 Want to get your electronics engineering challenge solved? Just invite me to your project on Upwork and I’ll invite you to book a complimentary consultation call with me. 📞 ❝ 𝙅𝙖𝙫𝙞𝙚𝙧 𝙤𝙛𝙛𝙚𝙧𝙨 𝙫𝙚𝙧𝙮 𝙙𝙚𝙚𝙥 𝙠𝙣𝙤𝙬𝙡𝙚𝙙𝙜𝙚 𝙤𝙛 𝙢𝙖𝙣𝙮 𝙨𝙪𝙗𝙟𝙚𝙘𝙩𝙨, 𝙖𝙣𝙙 𝙝𝙖𝙨 𝙖 𝙫𝙚𝙧𝙮 𝙥𝙧𝙖𝙜𝙢𝙖𝙩𝙞𝙘 𝙬𝙖𝙮 𝙤𝙛 𝙖𝙥𝙥𝙧𝙤𝙖𝙘𝙝𝙞𝙣𝙜 𝙨𝙤𝙡𝙪𝙩𝙞𝙤𝙣𝙨 𝙩𝙤 𝙙𝙚𝙨𝙞𝙜𝙣 𝙞𝙨𝙨𝙪𝙚𝙨.

Testimonials

Endorsements from past clients

"Discovering Javier's services was a big luck for us. He is the most reliable partner we've met in the EU for any new electronic product you want to develop. Honest, and transparent, he always delivers on time with a high quality. His work is always outstanding. But more than that he enriches his results with some "one step ahead" considerations, that pave the way to faster development and at a higher and higher value/money at every next interaction. That is what a usual thing with contractors - they request to redo a lot on every next iteration because it was for a purpose solution, it slows down and skyrockets costs. Javier does his magic and you never stick into such issues with him."
