Backend Developer delivering .NET APIs, scalable SQL/Oracle solutions, and automated ETL for business-critical reporting.
ColombiaWhat I'm looking for
I’m a creative backend developer who thrives in roles that combine technical execution with project management responsibilities. With over 4 years of hands-on delivery, I build and improve backend systems that connect applications, databases, and business needs.
At Banco de Bogotá, I developed .NET APIs that enable communication between applications and databases. I also managed and optimized database objects to ensure data integrity and scalability—especially for reporting and many accounting use cases.
I’ve focused on automation and quality: I automated accounting tasks through ETL created in Visual Studio, reducing errors and time in accounting closings. I also trained the development and support team to move from TFS to GIT, improving code management and documentation.
I collaborate across teams and stakeholders, translating requirements into user stories and helping manage the roadmap using Azure Devops. I also contribute to software quality through testing and continuous improvements, and earlier I supported upgrades and documentation at Tata Consultancy Services.
