Purpose-Driven
Engineer
There comes a point where a career is no longer about the next role, but the right impact.
That means aligning every line of code and every leadership decision with a single purpose: to improve our world.
About me
A hands-on technology leader dedicated to improving nature and society. I build product-focused, high-performance teams that deliver exceptional results through a culture of respect, accountability, and exemplary leadership.
By the way, I am a father of two, and have a past as a former american football player and assistant coach, champion of the 2000 Spanish National League with my team, Granollers Fènix. Also, I teached a style of brazilian zouk (couple dance) internationally, being the organizer of one of the most renowned and remembered international zouk events in the world between 2013 and 2017.

Scan 4 Points
Scan 4 Points is the most engaging feature of the World Mobile app. It allows users to scan the networks surrounding them, and get points for discovering new unscanned hexagons in the map. The data about the network is then sent to World Mobile, using it as the first layer of information on the decision-making process for network deployment.
I created the product specification, including the user flow, gamification, and data model; as well as the technical specification, including APIs, backend services, and more. I also participated in the implementation of some backend services.

Cephalea: Ceph backup system
Cephalea was a project created to solve the problem of backing up while processing inmense amounts of data, produced by one of the subsidiary companies of my client, MFCXY Inc.
This company had a problem: The nature of the content that they produce didn’t allow them to use public cloud services, and had to rely on on-premise open-source solutions, in this case, Ceph. The Ceph backup system was struggling to handle the amount of data that was being produced, and didn’t allow to have the filters and processing that they needed.
As a single contributor, I was tasked with creating a solution that not only would allow them to support their current needs, but also to be able to scale to the future. It has been running since June 2019. In the contract conditions, we agreed that by 2026 I would be allowed to open-source the solution, so I am looking forward to it.
AyA Whitepaper
AyA was born as a blockchain serving as the Telecommunications Settlement Layer of the EarthNode network, from World Mobile. Conceived as a Sidechain to Cardano, that served as Root of Trust, this paper was the first version of a series of future papers that aimed to generalize the solution to allow using multiple roots of trust.
After a pivot in World Mobile’s Strategy, AyA was not fully implemented, but it served as inspiration for some other projects.
Here you can read the paper that I co-authored.
World Mobile Chain Whitepaper
The World Mobile Chain whitepaper was the first version of World Mobile’s vision:
A shared economy model to deliver network infrastructure that would enable improvements in efficiencies of network design and operation, as well as provide a more fluid delivery of connectivity to users of a network.
As the CTO of World Mobile, I co-authored this paper, and architected the technical solution, including the blockchain integration, decentralized identity, encryption and privacy, NOC services, and more. I also created and led the team that implemented the system during the initial 5 years.
What they say about me
It was a pleasure to work with Antonio, a natural-born leader, charismatic, and has a special gift for management.
He is well versed in agile software development, not only in code architecture, but also in systems and infrastructure. He is uber pragmatic, always thinking and implementing with the goal that everything works in a performant way.
Great colleague and excellent CTO.
A true leader.
I had the pleasure of working alongside Antonio as the CTO during my time at WorldMobile. Antonio was an invaluable asset to our team, demonstrating exceptional technical expertise and an uncanny ability to quickly grasp complex concepts. His knowledge of Blockchain, DBs, architecture and cloud was truly impressive, and he was instrumental in guiding our team’s efforts in the challenging but promising field of blockchain.
Antonio was always willing to lend a hand, even diving into coding when necessary to help us meet tight deadlines or overcome technical obstacles. His accessibility and willingness to share his knowledge made him a fantastic mentor. I particularly appreciated his commitment to keeping the entire team informed about the company’s roadmap and goals, fostering a sense of shared purpose. Without a doubt, Antonio is a highly skilled and collaborative leader who I would be fortunate to work with again. I wholeheartedly recommend him for any technical role.
I had the privilege of working under Antonio Hernández during his tenure as CTO at World Mobile Group.
