As Engineering Manager for Marketplace, I lead a team of 10 engineers that built a headless ecommerce platform from scratch and shipped it to production - Next.js on web, React Native on mobile. I took it from concept to launch with product, design and business.

I set the technical bar for the platform - CI/CD, automated testing, performance optimization, and clean integrations with APIs, CMS, search engines, and PIM/DAM systems - and, just as deliberately, grow the people behind it: hiring, onboarding, mentoring, and career paths so the team scales with the product.

I'm also responsible for the growth team: the squad that grows the marketplace through continuous experimentation - hypotheses, A/B tests and impact measurement across the funnel - focused on acquisition and activation. Nothing scales without data behind it.

I led the engineering behind the first in-app commerce experience inside a banking app in Paraguay: an end-to-end purchase flow for the national team's official jerseys, where users could browse, buy, and complete the transaction without leaving the app. I coordinated product, engineering, design, and business teams against a fixed launch date - sold out.

As Engineering Manager I owned the technology of Camelus, an Argentine fintech regulated by the BCRA, taking it from a single lending product to five in production: loans, check discounting, investments, insurance and a digital wallet.

I designed the platform as four backends and five clients that share no database: one service issues identity, a stateless BFF re-signs a short-lived token on every request, and each domain owns its own data and events.

Because this is money and legal paperwork, the sensitive paths got the strict treatment: electronic signatures with HMAC-verified webhooks, TOTP on privileged actions, biometrics on mobile, and an audit row for every back-office write.

I also set how the team works: architecture decision records, runbooks and executable specs.

I led the mobile and frontend teams (4 developers) that built and scaled the first international prepaid Visa card with no issuance or maintenance fees, serving 50,000+ users - owning code quality, on-time delivery, and product impact end to end.

Beyond the app, the team delivered the back-office that runs the accounts and the merchant portal: merchant onboarding, points of sale, promotions and refunds. I brought developers on board as the scope grew.

Beyond delivery, I kept technology and business strategy aligned, driving process improvements and agile practices so the roadmap consistently translated into a better user experience.

I led the team of 6 developers behind the Quicktrade mobile app and the Grupo SBS web platforms - products used by over 1 million users to open a virtual wallet, track their investments daily, follow real-time capital market quotes, and trade stocks.

The app was followed by the web platform: full portfolio management, suggestions matched to the investor's profile and more complex orders on stocks, bonds, mutual funds and CEDEARs. I shaped the roadmap with product and design.

Those releases raised the bar for the user experience and helped position Quicktrade as a leading trading platform in the Argentine market.

At SBC I led frontend and backend teams shipping technology in two very different worlds: mobility apps for taxi drivers across the Riviera Maya and custom platforms for Mexican municipalities, adapting each solution to local needs and business goals.

Balancing delivery with mentoring, I kept quality high across projects while working directly with both public- and private-sector stakeholders.

At TryLikes I built IoT-driven feedback solutions deployed at 8+ global brands, including IKEA, McDonald's, Shell, Booking.com, Jumbo, PostNL, and MediaMarkt.

I developed and maintained the web and mobile applications behind them with React, Angular, Ionic, React Native and Flutter, keeping them fast and scalable across international deployments, while providing technical guidance and mentoring across multidisciplinary teams.

That work gave clients real-time customer insights - even offline - and helped TryLikes scale its product across multiple markets.

At Omochi IT I wore two hats - Senior Full Stack Developer and Project Manager - leading technology projects for clients across 7 countries: Argentina, the United States, Mexico, Japan, the UK, the Netherlands, and the United Arab Emirates.

I owned the technical strategy, kept clients and investors in the loop, and coordinated distributed teams to deliver on time - from e-commerce platforms and fashion apps for the Japanese market to inventory systems, travel booking platforms, school digitalization initiatives in Japan, and an internal social network for a multinational operating in 18+ countries.

Those years taught me to combine hands-on development with leadership - scaling solutions internationally and building client relationships that lasted.
