I will be your secure system developer or architect

DO YOU NEED A BACKEND ENGINEER WHO ALREADY SPEAKS "FINTECH"?

You're in the right place. I've spent 5 years building the backend systems that 

power real banking operations not tutorials, not side projects. Real systems, 

real clients, real money moving through them.

WHAT I DELIVER:

Java/Spring Boot microservices REST, event-driven, batch

Payment system integrations interbank, settlement, reconciliation

AWS Lambda serverless functions fully documented, production-ready

Core banking API integrations third-party apps, BPM systems, mobile

Database layer OracleSQL, PostgreSQL, MongoDB

WHO I'VE BUILT FOR:

Scotiabank Colpatria (x2 projects)

Banco de Occidente

Banco de Bogotá

Banco Popular

PORVENIR (Pension fund)

WHY CHOOSE ME:

- 5 years enterprise delivery at NTT DATA deadline-driven culture

- Regulatory-grade standards (Central Bank of Colombia compliance)

- Clean code, documented APIs, zero "mystery" codebases

- English communication throughout the engagement

- Timezone: Colombia (UTC-5) excellent overlap with US East Coast

Let's build something that works.
