I design and deliver robust Android systems for real users in production - from securing banking applications to shipping AI-enabled product features. Over a decade of mobile depth, backend pragmatism, and applied AI engineering, focused on solving high-impact product problems.
With 15+ years in Android development, I have focused intensely on building reliable, secure systems at production scale. At ABN AMRO, I contribute to the Security Guild, architecting solutions that protect millions of users and ensure trust in critical financial applications.
I ship AI-enabled capabilities that improve product outcomes in production, not only in demos. Beyond corporate projects, I tackle real-world problems with practical, rapid technological solutions - from crisis-response tools to widely-used community platforms.
Exploring the evolution of mobile and software engineering through key roles.
2019 - Present
ABN AMRO Bank
Architecting and shipping secure Android features for a banking app serving millions of users. Active contributor to the Security Guild - driving security-by-design practices, biometric authentication, and compliance across Android teams.
2016 - 2017 (Contract)
ING Bank
Led the implementation of fingerprint biometric authentication - one of the first in Dutch banking - and architected secure payment request flows used by millions of customers.
2014 - 2015 (Freelance)
WeTransfer
Built WeTransfer's first native Android app from zero - custom animations, minimal UI, and robust chunked uploads to AWS S3. Established the architecture that shipped v1 to market in a fast-paced startup environment.
2010 (Internship)
M2mobi (Heineken Campaign)
First professional Android role: developed performance-optimized UI for early mobile devices, including a complex slot-machine animation for a Heineken campaign. Deep focus on memory optimization and rendering performance.
Concrete outcomes from applying engineering skills to real-world problems - under pressure, at scale, for people who need it.
40,000+ users in a single day. Designed and deployed an incident mapping tool in under 24 hours during a major flood. Provided real-time data on services, power outages, and road blocks. Integrated directly with Argentinian military mapping experts via KML exports for coordinated response.
800 daily users for 11 years. Built a full-stack real-time bus information app that replaced the city's broken Flash-based site. Python/Jinja2 backend on Google App Engine, launched with guerrilla marketing (QR codes on bus stops). Became the de facto local resource until the city shipped its own solution.
Policy change achieved. A Python scraper to monitor consulate appointments grew organically into a large WhatsApp community. Led to direct collaboration with the Council of Residents from Spain (CRE) and a formal consultation with the Spanish Consul in Amsterdam - influencing real improvements in bureaucratic processes.
Mass-produced PPE for healthcare workers. Joined the Santander maker community during the pandemic to design and 3D-print ear protectors and face shields for medical staff. Parametric modeling in Fusion 360, rapid iteration, and community coordination under urgency.
Beyond product work, I build and experiment with technical hobbies that reinforce precision, long-horizon thinking, and disciplined execution.
A passion for turning digital ideas into physical objects, mastering parametric modeling with Fusion 360. From practical homelab solutions to contributing to community PPE efforts, I love the tangible aspect of creation.
A long-time Linux enthusiast, I enjoy building and maintaining my homelab, delving into containers, cloud solutions, and orchestrating personal systems. It is my playground for continuous learning and practical system architecture.
In Argentina, I built a 115mm Newtonian Dobsonian reflector with a handmade wood tube and mount, inspired by classic Stellafane designs. I use it from the southern hemisphere to observe Jupiter's moons, Saturn's rings, lunar craters, and deep-sky clusters and nebulae.
I recently started flying drones as a way to explore spatial awareness, field planning, and real-world system control. It is a practical hobby that pairs engineering curiosity with disciplined operation.
