About Saul Francisco

I am a software engineer and data architect with over a decade of experience leading projects in automation, data integration, and advanced analytics for companies across various sectors, including media, fintech, and technology. My specialty is transforming technical complexity into practical and scalable solutions: from orchestrating ETL processes and legacy system migrations to developing microservices, scraping, and integrating APIs and cloud services.

I differentiate myself by my ability to bridge the world of traditional data with the most innovative technologies. I am proficient in relational and NoSQL databases (ClickHouse, MySQL, Elasticsearch), and I also have experience with vector databases, text processing and vectorization for interaction with AI models, and advanced semantic analysis. I have implemented projects in trading automation, real-time analytics, advanced reporting, and AI-powered recommendation systems.

I work with modern infrastructures based on Docker, Airflow, ELK, Grafana, Tableau, and Kubernetes, and I manage CI/CD pipelines in both Bitbucket and GitLab. I adapt quickly to new challenges and teams, combining technical and business vision to create robust, documented, and sustainable solutions.

My goal is to help companies extract maximum value from their data, optimize processes, and modernize their infrastructure, whether through collaboration on integration, migration, advanced analytics, or automation projects. If you are looking for a professional capable of tackling complex problems and delivering real value from day one, I would be delighted to collaborate with you.

    Software engineer and data architect with over 10 years of experience in automation, integration, and advanced analytics. Specialist in ETL process orchestration in Python and Airflow, microservices development, scraping, and handling multiple external sources and APIs, including cloud service integration. Expert in infrastructures with Docker, ClickHouse, MySQL, ELK (Elasticsearch, Logstash, Kibana), Grafana, and Tableau, managing everything from legacy system migrations to dashboard development and business analysis.

    I have experience in vector databases (Qdrant, Elasticsearch), text vectorization, and designing systems for interaction with AI models, using artificial intelligence APIs for semantic analysis and recommendation systems. I develop data pipelines for enrichment and entity extraction, implementing solutions that connect natural language processing (NLP), machine learning, and automation, applying these approaches to reporting, trading automation projects, monitoring, and real-time analysis.

    I have deployed infrastructures in Docker Swarm and Kubernetes, and I manage CI/CD processes with Bitbucket and GitLab. I combine business analysis skills, technical documentation, team leadership, and support, always seeking efficiency, scalability, and sustainability.

    I hold an MSc in Computer Engineering, with experience in media and multidisciplinary projects, and a critical view on the social impact of technology. I speak Spanish, English, and Guarani, understand Catalan, Portuguese, and Italian, and adapt well to multicultural teams.

    If you are looking to connect business vision with technical reality, apply AI to data processes, automate and modernize infrastructures, I can provide innovative solutions in migration, semantic analysis, reporting, integration, and advanced automation.
