À propos de Antonio

I’m a hands-on Software Architect with 25+ years of experience designing and building complex, data-intensive platforms — especially where domain knowledge, scientific data, and legacy systems collide.

I specialize in turning fragmented data, undocumented systems, and evolving requirements into robust, scalable platforms that people actually use. I’m often brought in when projects are stuck, architectures are unclear, or the cost of “doing it wrong” is high.

Typical problems I solve:

- Modernizing legacy monoliths into efficient distributed architectures (e.g., cutting processing from weeks to hours in past migrations)

- Building unified knowledge platforms with graph + document/hybrid models (ArangoDB, Neo4j)
Designing scientific, laboratory, and R&D systems (from chemical identification tools to automated lab synchronizers)

- Delivering ERP-like platforms under aggressive deadlines (school transport management rebuilt in <4 months)

- Serving as “IT fireman” for mission-critical rescues and stabilizations

Core technologies: AWS, React, Node.js, Java, Python, PostgreSQL, graph databases (ArangoDB, Neo4j), strong CI/CD practices.

Currently open to senior architect roles, platform ownership, or high-impact consulting where technical depth meets real business understanding. If your project needs a prototype-first architect who turns facts (not just paper plans) into working magic—let’s connect.

(When things get really stuck, remember: even superheroes need a good cup of coffee before the rescue. ☕)

    ● Built an automated synchronization system to align experimental and processed data across laboratory workstations.

    Key Projects:

    ● Enhanced a monolithic application by introducing microservices and developing new features (Computer-Assisted Platform for identifying chemicals in aerosol components).
    ● Created a laboratory platform combining inventory, workflows, notifications, documentation, and reporting for biological assays (non-GLP ELN system).
    ● Delivered a GLP-validated platform for managing the inventory of climatic chambers.
    ● Designed a data exploration solution to process experimental information received in heterogeneous Excel formats.
    ● Implemented an IoT platform to capture sensor data in real time, apply transformations, and visualize results in Grafana dashboards.
    ● Developed firmware and control software for a custom aerosol sensor device (microcontroller + desktop application).
    ● Built a desktop control application for aerosol sensor devices.
    ● Designed and implemented an ERP system to manage and control trips for handicapped children using taxi drivers, ensuring efficient scheduling, monitoring, and reporting.

    Achievements:

    ● Recognized with two Excellence Awards from Philip Morris International R&D for outstanding contributions.
    ● Significantly improved user experience by streamlining access to data across multiple domains and repositories.
    ● Reduced system complexity and accelerated application development by optimizing CI/CD workflows (definition, configuration, and organization).
