I am a Senior Backend Engineer with more than 15 years of experience building high-scale distributed systems, payment infrastructure, and backend platforms. I specialize in Go, Java, Kotlin, Spring Boot, and cloud-native services designed for strict SLA environments.
I have worked on critical fintech and commerce systems at companies including PayPal, Mercado Pago, and Delivery Hero. My experience includes operating services that process millions of requests per minute and support customers and payment operations across dozens of countries.
I design resilient event-driven architectures using AWS SQS and SNS, microservices, asynchronous processing, Clean Architecture, and Hexagonal Architecture. I am experienced in system design, scalability, fault tolerance, performance optimization, and reliable API development.
I have strong platform and reliability engineering expertise, including observability practices with Datadog, Grafana, New Relic, Kibana, and Looker. I regularly work with SLI, SLO, SLA dashboards, incident response, WarRooms, post-mortems, and production troubleshooting.
I provide technical leadership through RFCs, ADRs, cross-team project ownership, mentoring, and stakeholder alignment. I am open to full-time remote opportunities and use AI engineering tools such as Claude Code and Cursor IDE to improve development workflows.
Developed and operated event-driven Java and Spring Boot services for large-scale buyer and merchant notification flows in PayPal's global payments infrastructure.
Investigated and resolved live production issues, helping maintain reliability for critical fintech systems in a globally distributed remote environment.
Designed and operated Java, Go, and Spring Boot fintech services processing more than 2.5 million requests per minute under strict SLAs across AWS and GCP. Led a three-year legacy migration affecting more than 175 million users without customer-facing impact, and reduced infrastructure costs by 15% through flow deprecation and processing consolidation.
Owned a regulatory banking project for Mercado Pago's licensed-bank transition in Mexico, covering planning, RFCs, ADRs, architecture, implementation, and stakeholder alignment. Built an internal live-issue analysis tool adopted by five engineering teams, established observability practices, led incident WarRooms and post-mortems, and mentored engineers.
Built and maintained backend services for high-traffic B2B and B2C e-commerce operations using Java, Spring Boot, and Hybris.
Developed REST API functionality for mobile applications and optimized SQL queries and caching to improve response times.
Developed and operated backend services in the Restaurant Ordering domain, supporting millions of daily orders across more than 40 countries. Designed resilient event-driven integrations with AWS SQS and SNS for asynchronous, fault-tolerant cross-team workflows.
Improved performance through Redis caching, DynamoDB, and efficient data modeling. Contributed to CI/CD delivery workflows using Kubernetes, Docker, Helm, and Spinnaker, and created Python and Gatling performance tests at up to five times production RPM.
Built internal automation and load-testing tools using Java and Spring Boot to improve the reliability of high-scale ordering systems.
Worked with JMeter, Ruby, Cucumber, and Angular to support test automation and performance engineering initiatives.
Built automation frameworks, backend utilities, and performance tooling for e-commerce, ERP, and POS systems.
Designed an Android automation SDK using the Calabash Framework that achieved more than 50,000 downloads. Worked with Java, Ruby, Selenium, Calabash, and JMeter.
