About
Hi, I’m Juan, a senior backend engineer focused on data-intensive systems, cloud-native backends, and AI-enabled product backends. I enjoy shipping robust, observable services and collaborating in remote-first teams to turn complex problems into reliable software. When not coding, I like shaping data pipelines, architectures, and platform decisions that scale with business needs.
I’ve led cloud migrations, redesigned monolithic apps into microservices, and built high-volume data processing across logistics, streaming, and finance. I’m energized by distributed systems challenges around AI models and data at scale, and I value ownership, pragmatism, and strong engineering practices.

AI platform that captures factory conveyor-belt images via mobile and detects product defects through AI analysis. Built critical microservices for high-volume image processing in a Java / Spring Boot / PostgreSQL ecosystem. Implemented AWS event-driven messaging with SNS/SQS and refined queue-polling mechanisms for reliable processing at scale. Created RESTful endpoints for mobile integration and provisioned infrastructure with Terraform. Optimized database queries and helped establish a stable production environment.
Cloud migration and LLM integration for an AI product. Maintained the API and OpenAI LLM integration (Node.js, NestJS, Next.js). Migrated the application from AWS to GCP (replacing Cognito, S3, SQS, Lambda with Firebase Auth, Cloud Storage, Pub/Sub, Cloud Run). Implemented IaC with Terraform and set up separate local, hybrid, and production environments with optimized CI/CD. Hardened security through VPC integration and controlled database access.
Led migration of on-prem Kubernetes clusters to GCP Cloud Run and Functions, enabling scalable infrastructure. Redesigned a monolithic application into domain-driven microservices, improving modularity and delivery speed. Built REST APIs (Java / Spring Boot), maintained CI/CD and IaC with Terraform, and established monitoring and alerting on GCP.
