Senior full-stack engineer crafting event-driven microservices and real-time cloud apps.
ColombiaWhat I'm looking for
I’m a Senior Fullstack Engineer with 8+ years of experience building full-stack applications using Node.js, Python, and TypeScript, with a strong focus on event-driven microservices, real-time systems, and cloud-native development.
In my recent role (Owner.com), I owned critical services such as loyalty programs, order management, payment gateways, and customer personalization—designing scalable architectures with strong reliability practices (SLIs/SLOs), high-availability APIs, and robust third-party integrations.
I also build for performance and operational excellence: Redis caching, optimized PostgreSQL schemas/queries, Kafka/RabbitMQ-based streaming and task queues, and end-to-end observability with AWS CloudWatch, AWS X-Ray, and OpenTelemetry. I’m energized by modern delivery (CI/CD with GitHub Actions, Docker, EKS, Terraform) and by shipping AI-powered personalization using AWS SageMaker, OpenAI API, and LangChain.

Improved performance and reliability using Kafka/RabbitMQ streaming, AWS ElastiCache/Redis, and strong observability; delivered 80%+ test coverage and a production CI/CD pipeline on EKS.
Developed real-time courier management and tracking systems, plus streaming ETL pipelines and delivery-assignment services. Built a Node.js SDK and courier portal (React) and improved delivery operations using real-time communication and well-tested, containerized deployments with monitoring via Prometheus/Grafana.
