About Alejandro

I am a Computer Science Engineer with over 15 years of experience in software

development, backend systems, and critical ICT infrastructures. I specialize in C++ and Python, with a strong focus on developing air traffic control systems, large-scale data processing, and operational analytics and intelligence platforms.

I have led the development of backend modules in C++ (Qt Creator, C++ 17) and Python (Django Rest Framework, Polars, Celery) for high-availability systems and massive real-time data processing, integrating technologies such as MongoDB, PostgreSQL, MySQL, TimescaleDB, Redis, RabbitMQ, Celery, and Grafana.

Additionally, I possess solid experience in virtualization, containers, and service
orchestration, mastering environments like Proxmox, Docker, VMware ESXi, DRBD, Corosync, and Prometheus.

My profile is complemented by experience in international microservices and payment gateway projects using TypeScript, NodeJS, NestJS, and GraphQL, as well as in Machine Learning (TensorFlow, Keras, Scikit-Learn) applied to medical image processing.

My personality highlights include analytical skills, systemic thinking, teamwork, and a results-oriented approach, offering a combination of technical solidity and a comprehensive architectural vision, ideal for research, development, and technological innovation environments.
