I build backend systems that work the first time and keep working after I leave. My last client hired me twice. The first time to build a custom eSign platform from scratch. The second time — three months later — to extend it, because the original architecture was clean enough to grow without rewriting. That's the kind of software I build. 10 years of enterprise backend development. I've built: → A loan processing engine for a banking platform — retail and corporate lending workflows, credit decisioning APIs, multi-stage approval pipelines → A custom eSign web application — full design and development, then seamless feature expansion for a returning client → A serverless inventory management system on AWS (Lambda + DynamoDB + API Gateway + Cognito) → Clinical documentation systems handling care gap detection across 31 medical categories I specialize in the kind of backend work where getting it wrong is expensive: financial services, healthcare, compliance-heavy domains. Systems where you need someone who thinks about edge cases before they become production incidents. Tech stack: Java 8/11/17 · Spring Boot · Spring Security · Spring Batch · Spring Data JPA · Hibernate · PostgreSQL · MySQL · Oracle · DynamoDB · Apache Kafka · Docker · REST APIs · AWS (Lambda, EC2, ECS, S3, Step Functions, API Gateway) · OAuth 2.0 · JWT · CI/CD (Jenkins, SonarQube) · 90%+ test coverage (JUnit 5, Mockito) 100% Job Success. Every project delivered on scope. Every client rated me 5 stars on communication and quality. Based in Colombia (EST-aligned). Fluent English and Spanish. Available 30+ hrs/week. I respond within hours, not days. Looking for a Java backend developer, Spring Boot specialist, or AWS microservices engineer? Let's talk about your project.
