Software Engineer at Santander Tecnologia Argentina (2022-03 – Present)
Maintain and evolve a nationwide distributed backend ecosystem for card logistics and digital banking, integrating with services owned by other domains, including Cards, Accounts, and Customers, through Apigee-secured OAuth 2.0 REST APIs. The ecosystem also combines asynchronous scheduled jobs, batch file processing, three Oracle databases, and multiple MongoDB stores. Use Kibana and Grafana for observability, Confluence for technical and functional documentation, and OpenAI Codex, GitHub Copilot, and Devin AI for multi-repository analysis, implementation, testing, and refactoring.
- Designed and automated a daily workflow that blocked approximately 800 cards destroyed at branches, replacing manual operational tasks and enabling customers to request card reprints through digital channels. Integrated card and customer services, classified Prisma failures, scheduled retry jobs, and routed unresolved cases through S3 and Control-M to an external RPA.
- Created an extensible scheduled-notification service that queried multiple domain services to process up to approximately 2,000 delivery candidates, sent around 400 push notifications for card-activation reminders per daily run on a seven-day cadence, and persisted campaign state in MongoDB to prevent duplicates and analyze subsequent activations.
- Developed a dedicated backend gateway for Pago Facil and Rapipago pickup operations and integrated the correspondent flow across six essential services of the card delivery platform; the initiative received quarterly MVP recognition.
- Launched the first greenfield Kotlin and Spring Boot service in the area under GLUON, integrating GitHub Actions, Kubernetes, OpenShift, S3, Control-M, and an external RPA; the implementation later served as a deployment reference for several teams.
- Contributed to a year-long brownfield migration to GLUON, moving applications from GitLab and Dumbo to GitHub-based workflows, OAM-managed application versions, and controlled deployments to OpenShift while continuing feature development and application maintenance.
- Implemented the core endpoints of a TypeScript and NestJS BFF that modernized a legacy cardless-withdrawal flow through services covering accounts, cards, legacy banking, risk evaluation, withdrawals, and customer notifications.
Founder & Software Engineer at Reals (2026-01 – Present)
Designed a pre-production Android dating app centered on compatibility, text-first interaction, progressive profile reveal, staged conversations, and user-safety workflows; owned product definition and technical direction across two repositories and three isolated environments.
- Engineered a Kotlin and Spring Boot backend on Java 21 and a Kotlin and Jetpack Compose Android app covering authentication, profiles, matchmaking, staged chats, text and audio messaging, visual decisions, scheduling, attendance, no-show, and account security.
- Deployed and tested an AWS development environment with GitHub Actions OIDC, SSM, EC2, Docker, private RDS PostgreSQL, and private S3 storage, validating complete multi-user flows from Android.
- Established an AI-native workflow based on scoped specifications, OpenAI Codex and other agents, architecture and diff review, focused testing, canonical documentation, and coordinated backend and Android changes.

Delivered end-to-end corporate banking functionality for Itau Uruguay across legacy Java 4/7 applications using Java, JavaScript, jQuery, Oracle, Maven, XML-based integrations, and manually deployed WAR packages.
- Implemented multi-stage financial workflows covering validation, roles, approvals, guarantees, back-office operations, and external payment integrations, including 3scale-mediated services.
- Improved high-volume screens through query, retrieval, and pagination optimizations while adapting heterogeneous provider rules and changing business requirements.
- Became a primary technical and functional reference within a reduced team, trained new developers, and contributed backend work to a Java 8 service-oriented banking platform for Banco Comafi.
