I am a Java Systems Engineer and Backend Developer with a 26-year evolutionary track record. My background is uniquely divided: half spent in the trenches as a bare-metal Unix Systems and Network Administrator, and the last 12+ years have been dedicated to building distributed Java architectures. My engineering philosophy is rooted in my academic and forensic background. Holding a 5-year Computer Engineering degree from UTN and a Postgraduate specialization in Cryptography and Telecommunications from the Army War College, my approach is evidence-based and security-first. Having worked in legal computer forensics, I don't treat systems as black boxes; I rely on hard telemetry, strict access boundaries, and verifiable data to solve complex problems. Today, my core focus is AI-augmented development. I use Large Language Models to accelerate code synthesis, while enforcing strict environment isolation (i.e. blocking model read-access to `.env` configurations, containerizing) to protect sensitive credentials and systems. My vision is to deliver highly efficient, pragmatic solutions to complex software and infrastructure challenges.
* Navigate cross-continental operational latency by presenting production-ready Proof of Concepts (POCs) to empirically de-risk feature adoption and earn architectural consensus. * Integrate LLMs for code synthesis, utilizing TDD invariants to prevent hallucinations. * Claude code skills development, agentic development. * Working on java & typescript ( nodejs, javascript ), security and architectural development to link new technologies to legacy applications. * Cloud develop & integration. * Front end development (React, Angular) Tech stuff: NodeJS, Typescript, Java, SpringBoot, python , postgres, Mysql, MariaDb, Docker,kind, kubernetes, AWS (Cognito, S3, DinamoDb, Lamdas ...), & frameworks (lot of them).
* Optimized backend architectures bridging legacy on-premises environments (Cloud Foundry) with AWS serverless stacks. * Supported a high-throughput data ingestion pipeline aggregating multi-segment Kafka streams. * Managed stream deduplication at the application layer using composite primary keys (mapping message/segment IDs) and "sent state" flags. * Migrate java 8 microservices to java 17. * TDD, mocks & immutability
* Engineered financial backends orchestrating through Heroku with direct AWS native integrations (Cognito, S3, EC2). * Working on Salesforce & DLTs technologies( like blockchain), security and architectural development to link new technologies to legacy applications. * Cloud develop & integration (Salesforce, Heroku, AWS, GCP, DLT's). * BI design Tech stuff of our team: NodeJS, Java, python , Docker, Ethereum, SmartContract, Solidity, Quorum, R3 Corda, Hyperledger , AWS (Cognito, S3 ...), GCP (Storage, functions,PubSub, BigQuery, DataPrep, DataStudio), Heroku (+CI) & frameworks (lot of them).
* Provided versatile backend and database support across relational engines. * Stabilized monolithic boundaries and integrated automated testing/telemetry hooks. * Developing and testing diverse PoC, to understand pros and cons on different technology flavors. Mostly as microservices to be deployed in Cloud platforms.
