Work experience
JULY 2023 - MARCH 2025

Senior Full-stack Engineer

Multimarkts

Multimarkts is one of the latest projects of nc43|tech, a visual shopping platform with AI features designed to enhance user engagement and monetization for media outlets and individual content creators.

I also worked briefly in other projects of the group, like Adsviu: an AI-powered cookieless contextual advertisement platform, and the rebirth of Billionhands, now aspiring to become an AI-enhanced rankings platform.

Personal Takeaways
  • First time working in proper AI-driven projects, both from the product perspective and the technical one
  • Also first time actually being a lead engineer, starting the R&D project with two engineers at my charge that would later become Multimarkts
  • Went back to work on the frontend too, after a long time focused on backend (I missed it!)
Tech Stack Highlights

Cursor, LLMs, TypeScript + NodeJS, MongoDB, Vue.js, Nuxt.js, Cloudinary, Redis, Docker, Terraform, AWS, CI/CD w/GitHub Actions

MAY 2022 - JANUARY 2023

Backend Engineer

Secfi

Secfi is the leading financial advisor for tech people, combining learning resources with powerful tools to get insights into your equity and offering financing among other resources to give back power to the people actually building the tech space.

I worked mostly in the Planning Domain, specially in the Equity Planner, an all-in-one tool to help you understand your exercise costs in detail, giving you all the info you need to act wisely.

Personal Takeaways
  • First proper startup (SF-like) experience: stressfully fun
  • Learned a fair amount about taxes and equity, not my cup of tea - but really good to know
  • First 100% international role and relocation, stressfully fun too + lots of self-improvement
  • Learned a lot about startup dynamics, leadership and rapid iteration
Tech Stack Highlights

Python + Django/FastAPI, microservices, kubernetes, PostgreSQL, Metabase

DECEMBER 2019 - MARCH 2022

Full-stack Developer

Billionhands (nc43|tech)

nc43|tech constitutes the technology branch of the NextChance group, known for their success with the spanish startup La Nevera Roja (adquired later by Just Eat).

My job was focused on Billionhands, a platform that aimed to become the Google for offers, providing access to more than 15M offers from stores all over the internet. In my last period there, we relaunched it with a focus on just fashion and home-deco and introduced visual search features.

Personal Takeaways
  • First more backend-focused role: I actually enjoy this too!
  • First contact with a startup-ish world, technically a venture builder, but focused on just 1 ever-changing product + small team
  • Amazing way of working, optimal amount of people + great set of methodologies made by and for everyone, continuously improving.
Tech Stack Highlights

TypeScript + NodeJS, MySQL, DDD, RabbitMQ, Redis, Docker, AWS, CI/CD w/Jenkins, real QA.

MARCH 2019 - DECEMBER 2019

Frontend Developer

ING Bank (via Sopra Steria)

ING is a Dutch multinational banking and financial services corporation, situated among the top 10 largest European companies by revenue.

I worked as a Front-End developer at ModelBank/Maggie, an ambitious project aimed to create a multi-country and multi-channel platform for Spain, Italy, France and Czech Republic.

Personal Takeaways
  • First role in a large enterprise environment: definitely not my cup of tea
  • First experience with scaled agile models
  • Dramatically improved my JavaScript and accessibility skills
  • Taught me the difficulties and risks in really large tech projects with quickly changing requirements + classic/hierarchical organisational models (goes wrong)
Tech Stack Highlights

JavaScript, web components, Storybook, Gitlab CI/CD, micro-frontends architecture (not a fan)

MARCH 2017 - FEBRUARY 2019

Full-stack Developer

Global Incubator (Capital Certainty)

Capital Certainty is a seed capital company focused on initiatives with both high economic return and positive social impact through sustainable business models.

I worked on multiple projects as a full-stack developer, primarily focused on front-end but also doing back-end development and DevOps tasks like internal tools, process automation and CI/CD.

Notable clients included Fintonic, PlayGround, Santander Bank, MAERSK Oil, and the Bill & Melinda Gates Foundation.

Personal Takeaways
  • Very first time working in a proffesional environment, really stressful but also an amazing learning experience
  • Learned to manage working on several different projects at the same time, with different teams and technologies
  • I was able to start modernizing the tech stack of the projects I worked on, with great results that ended up expanding to other projects in the company
