Gabriel has over seventeen years of experience working as a software developer, 5+ with TypeScript and 10+ with AWS. While his specialty was primarily in back-end development, he found a passion for DevOps to manage infrastructure and help improve teams' velocity and experience.

Work Experience

Software Engineer

2021 - PRESENT
  • Simplified the infrastructure, mainly in AWS and Terraform, with a large technical debt, reducing the number of pieces that could break. This also lowered the deployment time in CircleCI and areas to look in CloudWatch and Datadog when something fails.
  • Upgraded our infrastructure and processes to become SOC 2 compliant.
  • Set up a data warehouse and ETL for the BI team to run reports on instead of having external tools connecting to our core database, keeping our main database for transaction purposes, improving the end-user experience with reduced latency.
  • Created a new back end in TypeScript, GraphQL, and TypeORM to migrate from PostGraphile and Serverless to a more code-based solution that provided developers higher control and enabled them to safely write back-end features on a scale.
  • Migrated APIs, background task scripts, and queue workers from AWS ECS to EKS (Kubernetes).
  • Expanded our infrastructure from a single region to a multi-region to improve response times and experience for users in key geographical areas.

Developer | Co-founder

2020 - PRESENT
Virtual Dog Shows
  • Created an AWS-based infrastructure to serve the application, photos, and submitted videos (via Cloudinary) in the most cost-efficient way, using Terraform and Bitbucket Pipelines.
  • Partnered with a dog show judge to create an online platform where dog exhibitors can participate via video submissions that actual dog judges evaluate.
  • Managed payments from both ends (dog exhibitors and judges) using Stripe, Stripe Payout, and Stripe Connect.

A screenshot of the internal management software can be found here:

AKC Marketplace
A large web page developed with React and Laravel. Features include 10+ million visits per month, online transactions, recurring billing, server management with AWS, and internal and external APIs integration.

Technologies used include React, Laravel, AWS, ELB, EC2, S3, Elastic Transcoder, and RDS.

The project also includes a high throughput (several million requests a day) Node.js webhook handler for real-time chat with conversation over email support.

Dronestock Seller App
This project was developed in React and Laravel and allows sellers to upload high-quality videos. Features include a single-page app where sellers can upload 4k videos, which means that both the server and front-end app can manage and process multiple GB+ size files simultaneously. It generates lower-quality videos and publishes products to an existing Magento instance.
