About Victor

Mathematician by training, computer engineer by profession, with a solid track record as a data engineer, platform engineer, data scientist, and full stack developer.

I bring a rare mix of mathematical rigor, engineering expertise, and product-focused thinking, allowing me to design and implement end-to-end solutions that not only work — they deliver real business value.

Over the past year, I have been deeply involved in projects with large language models (LLMs) and Generative AI, particularly focused on designing solutions for sensitive data environments. I am experienced in on-premises deployments, open-source tools, and architectures that balance innovation with security and compliance.

In addition to AI work, I have strong experience in optimization projects, especially in the areas of logistics and routing (TSP, VRP), using advanced tools like Gurobi, CPLEX, and OR-Tools (Python). I enjoy transforming complex mathematical models into practical, high-performance applications.

My technology stack is broad and includes Python, Java, Airflow, Spark, Flutter, Angular, Power BI, Azure, AWS, Google Cloud, Jenkins, Kedro, Gurobi, Gremlin, and more. This versatility allows me to integrate smoothly into diverse teams and projects, from backend pipelines to cloud architectures to interactive front-end applications.

I am passionate about building solutions that are efficient, scalable, and secure. Whether you need someone to improve your data infrastructure, develop cutting-edge AI models, optimize your operations, or deliver full-stack products, I bring a hands-on, problem-solving approach combined with clear communication and focus on results.
