Enabl.es

CTO & Lead Developer I was recruited by the founders as a senior backend developer and, within two months, was appointed by the outgoing CTO to be his successor. This was a pivotal moment that defined my path as the “accidental CTO” — a leader who naturally steps up to take ownership of complex technical challenges. As CTO and lead developer, I immediately led the platform’s critical transformation into an open, event-source REST API. This was a strategic imperative, directly addressing the business team’s need for constant historical data projections and unlocking new integration capabilities. My role was deeply hands-on, encompassing both technical innovation and team leadership. I built and mentored a high-performing team, personally training them in methodologies like Domain-Driven Design (DDD) and Event Sourcing. Although the project concluded due to funding constraints, its true legacy was the highly skilled and resilient team we formed. I’m proud that I was able to bring many of these talented individuals with me to subsequent ventures — a testament to the strong, collaborative culture we created.

Euromillions.com

CTO & Lead Developer I was recruited for a focused, one-year engagement to lead a complete technical and cultural transformation of the Euromillions.com platform. The primary challenge was to overhaul a complex legacy codebase inherited from an outsourced team and establish a new standard for technical excellence. My mission was to drive a rapid turnaround and build a strong foundation for the platform’s future growth. Key achievements included: Platform Modernization: Spearheaded the adoption of modern software development best practices, including Scrum, eXtreme Programming (XP), TDD, and continuous deployment. This initiative resulted in dramatic improvements to platform performance, reliability, and quality. Team Building & Mentorship: Built a new, robust in-house technical and artistic team from the ground up, replacing the previous outsourced model. I personally mentored the team, empowering them with modern software development and DevOps methodologies.

VTS Media

Deputy General Manager Following my success as CTO, I was promoted to Deputy General Manager, working directly alongside the CEO to guide the company’s strategic expansion. In this executive role, I was tasked with stabilizing the company’s core product and its teams, successfully setting the stage for our next phase of growth. Spearheaded the company’s diversification strategy, overseeing the development of new products and leading the creation of new, specialized technical teams to support these initiatives. Focused on implementing rapid, iterative development cycles for new projects to accelerate time-to-market and maintain a competitive edge.

VTS Media

CTO & Lead Developer Recruited by a former co-founder, I joined this new venture as its first CTO and Lead Developer. I led the complete architectural transformation of the initial MVP, evolving it into a highly scalable and robust commercial product. Technical Leadership: Architected and executed the migration from a monolithic codebase to a modern, modular, service-oriented architecture, setting a new industry standard for handling high-traffic loads. Process & Methodology: Implemented Test-Driven Development (TDD) and Domain-Driven Design (DDD), which significantly enhanced the platform’s maintainability, performance, and reliability. Team Scaling: Grew the development team from an initial two-person unit to a high-performing team of 14 engineers, developers, and designers. Product Innovation: Bridged the gap between technology and product by designing and implementing some of the platform’s most sought-after gamification features. Agile Transformation: Championed the adoption of Agile methodologies, primarily Scrum, and became a certified Scrum Master to ensure our processes were efficient and effective. At the end of my tenure as CTO, amateur.tv was the number one video platform in Spain, and one of the top three Spanish-speaking ones in the world.

Electronic Life Solutions

CTO & Lead Developer When Electronic Life Solutions approached me to join as their CTO, I was immediately drawn to the demanding technical requirements of the role: building high-performance, scalable, and secure systems for real-time video streaming and payments. My focus on the complexity of the technical challenge was so complete that it wasn’t until the final stages of the hiring process that I discovered the specific industry they operated in. While unexpected, my philosophy until then had been that a fascinating and difficult technical problem is worth solving, regardless of the domain. As CTO, I embraced the challenge and directed all technology and creative operations for the company. My responsibilities included managing the technical and artistic teams, defining the technology roadmap, and overseeing the end-to-end development and maintenance of all digital products.

Codilink

Senior Backend Developer & Analyst At Codilink, I joined a pioneering company at the forefront of mobile marketing, developing one of the UK’s early QR code promotional voucher systems. As a senior technical leader, I was entrusted with one of the company’s key accounts, where I was the lead developer responsible for the core infrastructure. My role was pivotal in ensuring the security, scalability, and success of the platform. Lead Developer & Architect: I led the design and implementation of the project’s secure and scalable backend systems, taking full ownership of the technical architecture for a key company account. Hands-On Engineering: I engineered the core backend functionalities using PHP and Java, while also managing the complete database lifecycle, including advanced MySQL administration and replication. Security & Reliability: I was responsible for conducting comprehensive security audits to ensure the integrity and safety of the platform and its data.

Vespito

Backend Developer and Database Administrator After a successful exit from my first venture, I deliberately sought a role to deepen my expertise in backend systems. This led me to Vespito, a local consultancy and the official Spanish partner for MySQL. During my time there, I specialized in engineering robust backend systems using PHP and earned my official MySQL administrator certification. More importantly, this role was an opportunity to drive technical evolution from within. I identified key areas for improvement and championed the adoption of modern software engineering practices. I successfully introduced the company’s leadership to the value of: Version Control Systems for collaborative and reliable development. Unit Testing to ensure code quality and stability. Software Design Patterns to build more scalable and maintainable systems. This was also my first immersion into a fully remote environment, where I mastered the discipline and communication skills essential for effective distributed work—long before it became a global standard.

Perception Technologies

My first experience as a co-founder In 1999, alongside two university colleagues, I co-founded Perception Technologies with an ambitious vision: to build web-based applications that would revolutionize the local industry, inspired by pioneering digital studios like DoubleYou. We established a hybrid model, developing our own proprietary products while sustaining the business through strategic consulting for local clients. We successfully developed a portfolio of innovative products. However, when the dot-com bubble burst—a challenge felt acutely in Spain after the Terra debacle—we adapted to the new market reality. With venture capital becoming scarce, we strategically pivoted the company to focus entirely on our consultancy services, ensuring its resilience and continued growth. As the full-stack lead developer, I architected and built solutions using the core technologies of the era, including ASP, VisualBasic, PHP, and ActionScript. This foundational experience was about more than just code; it was an immersion in business strategy, product design, and the necessity of a pragmatic, customer-centric approach. In 2004, this chapter culminated in my first successful exit when I sold my stake to a new partner. I’m proud that the company continues to thrive today under the leadership of an original co-founder—a testament to the solid foundation we built.
