Brian Camilo Fajardo Sanchez

@briancamilofajardosa

I’m a solutions engineer specializing in API integration and real-time payment systems on AWS.

What I'm looking for

I’m looking for a role where I can own end-to-end API and payments integration delivery—designing scalable AWS solutions, validating acceptance criteria, and ensuring production-ready releases with testing and ITIL-based change management.

I’m a Solutions Engineer with 2 years of experience in API integration and real-time payment systems within Colombia’s national financial infrastructure. I progressed from hands-on iPaaS development (Digibee) to leading end-to-end solution design for enterprise payment integrations.

At Redeban, I contributed to the Bre-B integration node—Colombia’s national real-time payments network (comparable to Brazil’s Pix)—connecting 16+ financial institutions that processed 50M+ transactions in its first operational quarter. I’ve owned technical delivery end-to-end, designing integration architectures, writing API contracts and technical specification documents, and coordinating delivery teams to unblock progress quickly.

I bring a strong focus on scalability, reliability, and operational readiness: AWS provisioning (ECS, RDS, IAM), load testing with JMeter, and ITIL-based change management for production releases. I’m comfortable bridging product and engineering by validating acceptance criteria and presenting scope, risk assessment, and rollback plans before changes go live.
