Carlos Rodriguez — Senior Full-Stack Engineer

About Me

I'm a senior software engineer with 10+ years of experience spanning the full stack, with deep roots in backend systems, data processing pipelines, and machine learning. My career has taken me through healthcare, enterprise consulting, Salesforce ecosystems, and sports technology — and at every stop, I've been the person who connects raw data to real business outcomes.

At GMTM, I architect the systems that power a high-traffic sports technology platform: from the Stripe-powered subscription and payment infrastructure, to the web data access layer that gates purchased features and products, to the front-office dashboard that surfaces live SPARQ athletic performance data to users. I own the onboarding experience end-to-end and build the data visualization interfaces that make complex athlete metrics intuitive and actionable.

I have a deep fascination with economics and financial markets, and I'm currently building an automated quantitative trading algorithm — applying the same neural network and data pipeline skills I use professionally to model and predict market behavior.

Professional Experience

Senior Software Engineer

GMTM April 2021 – Present · Remote

Architect and lead developer on a high-traffic sports technology platform, responsible for the full product lifecycle from data ingestion to user-facing features.

Subscription & Payments: Built the Stripe-powered subscription model from the ground up — billing, plan management, feature gating, and purchase-based access control across the platform.
Data Processing & Access: Own the web data processing layer that determines what purchased features and products users can access, ensuring fast, secure, and accurate content delivery.
Front-Office Dashboard: Designed and built the dashboard that surfaces real-time SPARQ athletic performance data to coaches, scouts, and platform users.
Onboarding: Manage the end-to-end user onboarding experience, optimizing for activation and retention.
Machine Learning: Implement TensorFlow/Keras neural networks for predictive models and data-driven features.
Data Visualization: Build the interactive data visualization interfaces that make complex athlete metrics clear and actionable.
