About this gig
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

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.
