Nuvemshop
Software Engineer
Aug 2019 – Nov 2025Buenos Aires · Hybrid
For more than six years I worked on a large-scale e-commerce platform, across the Payments, Promotions, and Account & Security domains, as well as cross-cutting services.
I owned backend and frontend work end to end across the platform core, the store admin panel, the storefront, and checkout: from technical design and API contracts through implementation, testing, deployment, and production monitoring.
I provided technical leadership within agile teams, collaborating with Product, Design, and Engineering and using Jira for planning and tracking. Day to day, I used Docker for local development environments; GitHub Actions, CircleCI, and Argo CD for validation workflows, automated tests, and deployments to staging and production; and Datadog, Kibana, and Loggly for logs, metrics, traces, dashboards, and monitoring.

Payments
2019–2023
Payments
Helped design the transition from native integrations to an API- and microservices-based platform, and led development of its core services with Scala, Akka, Play, and MongoDB. The platform enabled integrations with 30+ payment providers across five countries.
01 · Context
The platform relied on native, one-off integrations with each payment provider, which made it costly to add new providers and expand into new countries.
02 · Architecture
I helped design an API- and microservices-based platform that decoupled checkout from each provider's specific integration, with common contracts for onboarding, charges, refunds, and notifications.
03 · Implementation
I led development of the platform's core services with Scala, Akka, Play, and MongoDB, and supported the progressive migration of existing providers to the new model without interrupting ongoing operations.
04 · Public API
I wrote the specifications and documentation for the payments platform's public API, aimed at making it simpler to integrate new providers.
05 · Security
We added validations and additional controls to reduce fraud and protect sensitive payment data, in line with each provider's and country's requirements.
06 · Expansion
The new architecture made it possible to integrate 30+ payment providers across five countries (Argentina, Brazil, Mexico, Colombia, and Chile), adapting to each region's regulatory and market particularities.
07 · Result
The platform simplified integrating new payment providers and made regional expansion of Nuvemshop's checkout easier.

Account & Security
2024
Account & Security
Took part in building a new domain focused on account security, authentication, permissions, and session management, and in implementing 2FA and controls for sensitive actions.
01 · Context
Account security and access management were spread across several domains, with no unified view of authentication, permissions, and sessions.
02 · Design
I took part in designing a dedicated domain to centralize authentication, permissions, and session management, with a data and event model built to scale to new security use cases.
03 · Implementation
I took part in implementing two-factor authentication (2FA), session management, and additional controls for sensitive account actions, reducing the risk surface against unauthorized access.
04 · Result
We laid the groundwork for a dedicated account security domain, able to evolve toward new access controls and policies.
2024–2025
Promotions
2024–2025
Promotions
Nuvemshop's promotions were basic, and many sellers relied on third-party apps. I contributed to building a dedicated domain with Java, Spring, and PostgreSQL, featuring more flexible discounts, combination rules, and a public API.
01 · Context
The platform's native promotions were limited (mainly simple discounts), so many sellers turned to third-party apps to build more sophisticated promotions.
02 · Design
We designed a dedicated promotions domain with more flexible discounts (by product, category, order value, free shipping, among others) and rules for combining them.
03 · Implementation
I contributed to developing the domain's services with Java, Spring, and PostgreSQL, using Redis to cache promotions.
04 · Public API
We exposed a public discounts API so partners and third-party apps could integrate with the new promotions engine, expanding the ecosystem around the domain.
05 · Coordination
I worked closely with Product, Design, and the Checkout and Catalog teams to ensure promotions behaved consistently across the platform.
06 · Result
The new domain gave sellers more flexibility to build campaigns without relying on third-party apps, and the public API enabled partners and apps to integrate with the promotions engine.

Store Activity Logs
2024–2025
Store Activity Logs
Designed and implemented, end to end, a cross-cutting service to record and query user actions, built with Node.js, NestJS, TypeScript, Kafka, and Elasticsearch. I documented it, presented it to Engineering, and other domains adopted it.
01 · Context
There was no standardized way to record and query the actions users performed within the store admin panel, which made traceability and incident investigation harder.
02 · Design & Implementation
I designed and implemented the service with Node.js, NestJS, TypeScript, Kafka, and Elasticsearch, built to be consumed by multiple platform domains without coupling to each one's business logic.
03 · Infrastructure
I deployed and monitored Elasticsearch and Kibana on AWS EC2 to store and query the logs.
04 · Adoption
I documented the service and presented it to Engineering; following that presentation, other domains adopted it to record their own user actions.
05 · Result
The service standardized how user actions are recorded across the platform and made traceability and incident investigation easier, without each domain having to build its own logging.
