I am a senior backend engineer with more than eight years of experience building, modernizing, and supporting enterprise applications across logistics, financial services, IoT, and education.
I specialize in Java, Spring Boot, REST APIs, microservices, reactive systems, and event-driven architectures. I have built reliable backend platforms using Kafka, SQS, MQTT, Redis, relational and NoSQL databases, and AWS serverless services.
I have hands-on cloud and infrastructure experience with AWS, Azure, DigitalOcean, Docker, Terraform, CI/CD pipelines, and production observability through Grafana, Prometheus, and OpenTelemetry.
I have led technical decisions, architecture discussions, code reviews, pair programming, and mentoring for small engineering teams. I focus on practical improvements to reliability, performance, scalability, and maintainability.
I have delivered production AI capabilities, including an internal LLM-powered reporting assistant integrated with company databases. I am available for remote roles in the UTC-4 time zone and communicate professionally in Spanish and upper-intermediate English.
Worked remotely through engagements embedded in client engineering teams, serving as a senior software engineer and technical lead across IoT, logistics, enterprise software, and education platforms.
Provided architecture input, implementation leadership, code reviews, mentoring, pair programming, and coordination for small development teams while delivering backend, cloud, infrastructure, and full-stack solutions.
Designed and built a serverless, event-driven backend for an IoT device management platform using AWS Lambda, EventBridge, SQS, DynamoDB, API Gateway, IoT Core, IAM, and Terraform.
Implemented OpenAPI 3-defined REST APIs for device-status retrieval and command delivery. Built SQS, MQTT, and AWS IoT Core workflows connecting backend services with devices, and defined user and device access controls.
Built and deployed an internal management AI assistant that connected Gemini and later Claude to the company database, enabling natural-language data queries and report generation. Worked on Gradle-based Java microservices, Vue 2 frontend features, Auth0 authentication, Google Maps integration, and AWS services.
Stabilized billing and logistics services under heavy calculation loads through Redis caching, SQS queues, batch jobs, background invoice processing, and gradual data loading. Reduced query latency by 30% and changed recurring outages into extended periods without reported downtime. Managed Liquibase migrations, Docker containerization, testing, reviews, and a TensorFlow barcode and QR recognition proof of concept.
Maintained and modernized enterprise applications by migrating tools to newer Java and Spring Boot versions. Built replacement applications supporting battery logistics and warranty traceability workflows.
Implemented internal and external access management, including LDAP authentication for employees and access for external agents. Contributed to a partner-management solution that forecast battery ordering needs from historic sales data, and built Angular and TypeScript frontend applications.
Led backend, infrastructure, server configuration, and deployment decisions for a virtual classroom platform with video classes, shared files, reports, and evaluations. Supported a production environment serving up to 500 recurring users.
Monitored production health and performance with Grafana, Prometheus, and OpenTelemetry. Automated DigitalOcean server deployment and load-based scaling with Bash and infrastructure APIs, and used Spring WebFlux for real-time data. Guided a team of two to five developers through task coordination, code reviews, and pair programming.
Maintained an iOS application using Swift and Objective-C during a short-term senior software development engagement.
Adapted the application interface for iOS 13 changes while preserving compatibility with devices running iOS 6.
Enhanced a Java and Spring Boot application for bank reconciliation based on data derived from SWIFT processing workflows. The engagement was remote and concurrent with the EMA Holdings role.
Refined funds, account, and origin and destination bank data so the finance department could complete reconciliation more effectively. The backend application was hosted on Microsoft Azure.
Developed features for an electronic wallet platform, including digital balances, user transfers, and merchant payments. Contributed to a hotel-management module in iDempiere covering rooms, reservations, events, and special-product billing.
Built REST APIs and JasperReports reporting with Java, Spring, and PostgreSQL. Improved API response times by 25% through SQL optimization, indexing, and caching, and configured ActiveMQ to connect servers across locations through VPNs.
