• Manage and lead a team of 3 people, 1 senior and 1 junior engineer plus a CS person.
• Decide on the technological stack of the products and architect the infrastructure foundations.
• Plan the business model with CEOs and Shareholders.
• Design, control and execute the technical roadmap.
• Implant Agile methodologies and meetings as much as possible.
• Talk directly to customers, potential clients and Spanish public administrations to give support to sales and explain or solve technical doubts.
• Lead the next steps in the product, aiming for new unachieved milestones to create small blue oceans, or partnering with other prospects.
• Conduct hiring sessions.
• Control technical costs and forecasting.
• Embrace and integrate AI into our internal and external processes and tools.

And below that, I continue involving myself in programming:

• Mentor and tutor the developers.
• Migrate legacy code, fix bugs, develop features, etc…
• The rest, you already know it!

• Participated in the codebase migration to new technologies, frameworks and principles. To be precise, separating an EJS front-end tightly coupled to an Express JS backend into a pure React 18 app with an independent new Express TS submodule.
• Maintained legacy features and endpoints in the mentioned technologies.
• Developed new APIs and features in the migrated codebases.
• Worked and specialised in the B2B squad, but thanks to my knowledge of the entire codebase, gave support to other squads in need like the Growth and B2C squads.
• Focused on enhancing the velocity and efficiency of APIs, mainly refactoring mongo queries and code, with a median of ~34x in velocity, with exceptional cases of ~77x.
• Also focused on enhancing React performance of heavy pages, using lazy loading techniques, cache systems and pre-renderings to make the “First Contentful Paint” faster.
• Later moved on to give major support and lead, for a time, the Careers squad, then moved back to B2B to help deliver a major feature of the SOC Simulator, digging deep into AWS on-demand machines, VMs and other resources, working hand in hand with the Content (Cyber) engineers.
• Always kept close contact with UX/UI designers, Product Managers, Customer Success and Sales, where I even had meetings with potential B2B prospects and leads.
• Participated in internal Hackathons, Go To Market Weeks and Brainstorming sessions with CEOs, POs, PMs and stakeholders to find, discuss and execute solutions for B2B…
• Mentored and tutored new developers in the different squads I participated in and gave support to.
• Also absorbed the strong A/B testing mentality of the company.
• Worked on an experimental flow for B2C-2B growth.

• Started applying TDD (Test Driven Development) backed by DDD (Domain Driven Design).
• Built and maintained API services.
• Built new microservices and controlled the network in Kubernetes.
• Developed and engineered the frontend logic with Angular 13 and Pug.
• Had learning sessions and business talks with the CTO, who kind of ended up being my implicit mentor.

As data miner manager:

• Created and maintained all of the crawler network to obtain in-depth data from numerous platforms in Spain (like Airbnb, Booking, TripAdvisor… and many more) from their internal APIs, or in some specific and small cases from web services.
• Managed the post-crawling processes involved, like cleaning, normalising and analysing the data, readying it to be consumed.
• Built Backend services for the other teams in the company to consume and interact with the data.

As a junior Front-end dev:

• Refactored small to medium complexity components in our Angular 8 application.
• Developed new features and logic, tutored by my assigned senior full stack developer.
• Started working back to back with a UX/UI designer.
• Entered into the Agile environment.

• Graduated in Computer Science with a bachelor’s degree at the University of Barcelona, where I took a variety of subjects ranging from maths to physics, Operating Systems to Artificial Vision/Intelligence, etc…
• For the record, I was not an outstanding student, as I struggled in the very first years, but managed to get the rhythm back, getting an “outstanding” grade on my bachelor’s thesis, where I created a website that tried to forecast Bitcoin’s price using the machine learning models available at that time (2015).
• I also began my professional journey by starting to work half time for a company during my 4th and last college year, at what would later become my first full time job.
