10+ years building and securing production systems: AWS architecture, CI/CD pipelines, server hardening, and full-stack applications for banking, healthcare, and government.

About me

From code to infrastructure

I'm a software engineer with over 10 years of experience taking systems from design to production. My specialty is the point where code meets infrastructure: AWS architectures, CI/CD pipelines, Linux server administration and hardening, and security audits on systems in operation.

I come from full-stack development —React, Angular, and Vue on the frontend; Laravel, Node.js, and Python on the backend— which lets me design infrastructure understanding what applications actually need, and write code understanding where it will fail in production.

I've worked on high-traffic financial systems at Grupo Salinas, hospital platforms built from scratch, and government systems integrated with federal registries.

Experience

My work

Frontend Engineer & Tech Mentor

Grupo Salinas | 2022 - present

Led the migration of two monolithic systems to a micro frontends architecture: the API deployment management platform for the Transformation Factory area (~200 internal users) and the human resources system for workforce metrics and payroll management. Defined the code and CI standards for React, Angular, and Vue adopted by multiple teams, and designed and taught internal web development courses.

API Architect

Grupo Salinas | 2021 - 2022

Designed OpenAPI contracts that standardized backend service integration across the group's business units. Implemented performance testing to validate service behavior under real production load.

Full-Stack Developer

Iterando | 2018 - 2021

Architected the company's employee management system end to end: frontend, backend, data model, and production deployment infrastructure. Built platforms with real-time data and owned the infrastructure decisions: server configuration, Nginx, SSL, backups, and monitoring.

Web Developer

Attorney General's Office of the State of Veracruz | 2018

Built the vehicle theft reporting system integrated with REPUVE (the federal Public Vehicle Registry), designed for state-wide operation. The system processed ~100 reports per day in its initial deployment in Xalapa, handling sensitive complainant data with role-based access control.

Web Developer

"Dr. Rafael Lucio" High Specialty Medical Center (CAE) | 2015 - 2016

Built from scratch the purchasing, medical supplies inventory, and study costing system for one of the reference public hospitals in southern-southeastern Mexico (196 beds, ~100,000 patients treated per year). The platform centralized supply records and study cost calculation for the hospital's administrative area.

Services

What I do

AWS architecture & infrastructure

Cloud architecture design: compute, storage, queues, and serverless, with well-scoped IAM and networking.

CI/CD & deployment automation

Complete pipelines: build, testing, security analysis, and automated deployment.

Security & hardening

Audits of production servers, remediation of findings, and secure configuration of Linux, Nginx, and certificates.

Full-stack development

Complete applications with React/Angular/Vue + Laravel/Node, from data design to production.

Frontend architecture at scale

Micro frontends, code standards, and migration strategies for large teams.

Technical mentoring

Team training, code reviews, and standards definition.

Projects

What I built

AWS Reference Stack — infrastructure as code

A production-shaped AWS architecture described entirely in Terraform: a containerized web service behind a load balancer and an asynchronous worker pipeline, wired together with least-privilege IAM. It deploys with terraform apply and nothing else.

  • Terraform
  • AWS
  • ECS Fargate
  • SQS
  • Lambda
  • IAM
  • Two availability zones, with compute tasks in private subnets and egress through a single NAT gateway.
  • A job queue with a dead-letter queue after three failures, so one poison message cannot stall the consumer.
  • Every IAM permission scoped to the resource that needs it: no wildcard policies.
