}Systems engineer focused on backend and architecture.
Software architecture and development lead with more than 6 years of experience, specialized in the banking sector.
Responsible for defining the architecture of high-impact projects such as payments integration, financial channels and online banking, and for standardizing development through archetypes, core dependencies and central Maven repositories (GitLab).
Main stack: Java 21 (Spring Boot 4 and 3, Quarkus), TypeScript (Angular), Python, Oracle (PL/SQL), Docker, Kafka and gRPC.
Highlighted projects: integration with Banred, financial channels with Western Union, refactoring of payroll payments with a distributed architecture and synchronous/asynchronous messaging, and implementation of two-factor authentication (OAuth 2.0 + Keycloak) and OTP for online banking.

Case studies: the problem, the solution and the result.
Integrate interbank payments and B2B channels with strong authentication and no risk to transactions.
Distributed architecture with OAuth 2.0 and Keycloak, built on core artifacts in Java 21 and Spring Boot 4.
Direct payments and B2B channels integrated with strong authentication, on core artifacts that other projects reuse.
Kafka, gRPC, Spring Boot
Problem. The payroll payment process had to scale and tolerate failures.
Solution. Distributed architecture with synchronous and asynchronous messaging.
A decoupled payroll process: services talk through messaging and each part can scale on its own.
OAuth 2.0, Keycloak, Java 21
Problem. Online banking needed a second authentication factor to operate securely.
Solution. A two-factor authentication engine with OTP on top of Keycloak.
Second factor and OTP available in online banking, with a reusable authentication engine.
Maven, GitLab, Docker Swarm, Traefik
Problem. Every Spring Boot project started with different conventions.
Solution. A central Maven repository, archetypes, core dependencies and GitLab deployments.
New projects that start with the same conventions, dependencies and deployments, without repeating setup.
More than six years in banking, telecommunications and manufacturing.

What people who worked with me say.
Jose Paredes
BA in Computer Science & Business Analytics, The George Washington University
From day one he was always open to helping and teaching me, with enormous patience, and never made me feel that a question was too basic. … His guidance gave me the confidence to take on a real project in a banking environment and start contributing to the team. … Jonathan combines technical strength with a genuine vocation for teaching.
I am looking for an architecture or backend role, and freelance projects.
