Data Ops Assistant
I am starting a new professional stage at Ixatu.com, focused on data administration, digital operations, process improvement, and the practical use of data to support business decisions. After more than 18 years as a Full-Stack Developer, I am now orienting my career toward data, analytics, ETL, automation, and AI-assisted workflows. My background in software development gives me a strong technical foundation, while my current focus is on helping organizations improve how they capture, validate, organize, monitor, and use their operational data. Previously, I worked at Centraldereservas.com, where I contributed to the design, development, and maintenance of internal and customer-facing systems using PHP, JavaScript, and MySQL. This experience gave me a deep understanding of business processes, databases, internal tools, and production software environments. In parallel, I continue developing Store ETL, a personal data engineering project based on PostgreSQL, Python, Docker, Dagster, Liquibase, FastAPI, Grafana, and modern ETL principles. Through this project, I work on traceable pipelines, data quality, schema versioning, observability, and scalable data workflows inspired by Medallion and MDM architectures. My professional goal is to grow as a data-focused profile, combining administrative accuracy, technical depth, analytics, automation, and practical business understanding. Core Skills: * Data Administration & Digital Operations * ETL, SQL, PostgreSQL, Python, Docker, Dagster, Liquibase * Data Quality, Observability, Documentation, Process Improvement * Machine Learning, NLP, EDA, A/B Testing * Full-Stack Development: PHP, JavaScript, TypeScript, React, Node.js, MySQL * Knowledge Management, Obsidian, AI-assisted workflows

Cultural Fit Analysis
The candidate demonstrates a strong passion for learning and applying new technologies, as evidenced by numerous personal projects in AI/ML, data engineering, and knowledge management. The diversity of projects, from AI-powered developer environments to data platforms and NLP applications, indicates a broad interest and adaptability. The candidate's recent bootcamp and ongoing personal projects suggest a proactive approach to skill development, which is a positive cultural indicator. However, the professional experience, while extensive, is largely in application development and data operations, not directly in a senior ML engineering capacity, which could present a gap in cultural fit for a purely research- or model-centric ML team without significant upskilling.
Soft Skills & Operational Fit
The candidate's project descriptions highlight actions and results, indicating a results-oriented approach. The long tenure at Centraldereservas.com suggests loyalty and the ability to contribute to diverse projects over time. The focus on personal projects demonstrates initiative and continuous learning. However, the professional experience in a direct ML Engineer role is limited, and recent professional roles are not directly aligned with senior ML engineering, which might impact operational fit for a high-autonomy role.
