- POS Performance: Restructured core POS architecture using Fastify/Node.js, optimizing business logic to reduce response latency by 30% and stabilizing the system for high-concurrency peak loads. - Reliability & Security: Led the resolution of technical debt and critical security bugs, substantially increasing system stability in high-concurrency environments.

Data & AI Strategy: Designed and orchestrated a scalable data platform for AI adoption, leading ETL pipeline development and data structuring to support massive-scale predictive modeling.

Microservices Architecture: Led the strategic migration from a PHP monolith to Microservices, decoupling the frontend (React) and backend, which improved deployment frequency and system maintainability.

Scalable Architecture: Designed modular, high-performance backend solutions, prioritizing maintainability and service decoupling.

Led the development of web and mobile applications for management reporting, ensuring data consistency and query optimization on the backend.

Implemented robust web applications for the administrative management of internal processes, focusing on operational efficiency and information security.

- Technology Strategy: Defined and maintained the technological innovation strategy aligning software development with the company's commercial vision. - Leadership: Managed the full lifecycle of the company's key technological products.

- Project Management: Prioritized software projects and defined timelines, assigning tasks and supervising the performance of junior developers. - UX/UI: Collaborated on defining UI/UX elements, creating mockups to guide the design process.

Full-Cycle Development: Identified user requirements and developed code for new applications, performing testing and debugging to ensure reliability and performance.

Developed and maintained PHP web applications, covering the full scope from requirements gathering to testing and code debugging.

Data Analysis: Managed procurement for aircraft maintenance and implemented forecasting models and demand analysis using innovative technologies.

Java EE Development: Prioritized and executed tasks throughout the software development lifecycle, designing the database architecture and documenting development phases.

- MLOps Pipeline: Engineered an automated "end-to-end" pipeline for ML model retraining, versioning, and deployment using Python and Scikit-learn. - Architecture: Developed a Contract-Driven system (OpenAPI) using Hexagonal Architecture and Node.js (Fastify) to bridge massive data ingestion with real-time predictive inference. - Data Engineering: Implemented robust processing workflows for cleaning and structuring historical datasets in PostgreSQL, optimizing them for large-scale predictive modeling.
