Profile Summary

I'm a Senior Developer with 11 years of experience. I began my career at a consultancy where I worked on a variety of projects and technologies, including e-commerce, retail systems, financial systems, CRM integrations, and on-site client deployments. Currently, I work in the mobile marketing sector (initially a startup), where we perform data collection via scraping and process high volumes of data using various microservices and AI to generate dashboards and reports. I also build multiple APIs, creating scalable and robust architectures, always employing development and security best practices, design patterns, and performance monitoring tools, while optimizing and indexing SQL and NoSQL databases. Through this experience, I have gained solid expertise in agile methodologies (Scrum and Kanban), working with over 40 microservices including crawlers, web scraping, APIs, platforms, and integrations, utilizing message queues for communication between them. I actively and proactively develop in technologies such as Node.js, TypeScript, JavaScript, RabbitMQ, NestJS, Express, C# .NET, React, Docker, and Redis. Additionally, I have honed my soft skills, including communication, emotional intelligence, resilience, critical thinking, adaptability, and the ability to give and receive constructive feedback effectively.
