About

Nicolás is a Backend Developer with six years specializing in fintech. At Bamboo Payments, he led the end-to-end migration of a payments microservice's data layer, porting 51 tables and 83 stored procedures to PostgreSQL with zero-downtime. He also re-architected a report-generation pipeline, resolving production out-of-memory crashes, enabling large reports (500K+ records) to run. Earlier, at TAG Latam and Shifta, he automated PostgreSQL schema management with Flyway and Kubernetes (replacing 193 legacy migrations) and built reporting APIs for analytics. He holds a Systems Engineering degree from Universidad Tecnológica Nacional. His toolkit includes AWS services like Aurora, EKS, RDS. He thrives on solving complex problems via system internals. He seeks to deepen his backend and fintech expertise on a remote international team. Outside work, he builds personal projects like a chatbot with the OpenAI API to deepen his learning. His B2 English proficiency supports effective communication in remote international settings.
