# Marco Gonzalez > Senior Software Engineer | Full-Stack Development (React, Ruby on Rails, Node.js, TypeScript, Python, AWS) Location: Orlando, Florida, United States Profile: https://flows.cv/marcogonzalez I’m passionate about solving complex engineering problems and making systems more reliable, scalable, and efficient. At Valor Performance, I optimized a HubSpot sync service to process 85k+ database fields in under a minute, automated 60+ client reports with Python + AWS Lambda, and modernized a 5-year-old JavaScript stack for speed and security. Contributor to open source through astroSpeed, where I built Node.js + Puppeteer performance auditing tools. My background in systems and reliability engineering trained me to think holistically, optimize for efficiency, and design for reliability — principles I now apply directly to software scalability and optimization. ## Work Experience ### Senior Software Engineer @ Valor Performance, Inc. Jan 2022 – Present I worked across the full stack (React, Ruby on Rails, GraphQL, PostgreSQL, AWS) to improve platform performance, reliability, and usability for a coaching and wellness SaaS product. • Improved marketing data accuracy by creating a Ruby on Rails sync service for 5,000+ clients (~85k PostgreSQL fields), cutting runtime from 1 hr to <1 min through HubSpot’s batch API and optimized database queries. • Prevented dozens of Helpdesk requests each month and increased admin efficiency by developing a React + GraphQL page to precisely query multi-table data, enabling auditing and filtering of client changes. • Eliminated 95% of deployment failures caused by dependency mismatches by implementing Python Poetry and standardizing Docker/server environments. • Empowered Customer Success and Sales teams by automating 60+ client usage reports using Python, Pandas, PostgreSQL, and AWS Lambda. • Enhanced team productivity by mentoring junior engineers, establishing code standards, reviewing 150+ pull requests, and pairing on 100+ sessions — raising code quality and accelerating feature delivery. • Ensured platform uptime as rotating Helpdesk lead, resolving urgent production issues such as site outages, data corruption, and deployment errors to minimize downtime. • Modernized JavaScript stack by upgrading React, Webpack, Babel, Node.js, and related packages (5+ years outdated), enhancing security, reducing load times, and enabling modern development features. • Reduced unlogged sessions by 90% by creating Sidekiq email workers and a React Router page with session tracking and pagination, ensuring accurate reporting and timely coach payouts. • Delivered dynamic Material UI components for 50+ coach bios, adapting to variable content while maintaining a responsive, consistent user experience. ### Software Engineer @ astroSpeed Jan 2022 – Jan 2022 I contributed to an accelerator-backed open-source project focused on web performance tooling. • Streamlined developer workflows by publishing an npm package with Git hooks to run automated audits, ensuring consistent performance tracking. • Automated performance audits by creating a Node + Puppeteer pipeline to run Lighthouse tests post-commit and visualize results with ApexCharts. • Optimized web performance for a responsive Astro + Tailwind marketing site for fast load times. ### Mechanical Engineer @ Lockheed Martin via PSCI Jan 2019 – Jan 2021 | Orlando, Florida, United States • Employed Creo CAD/Simulation to design test platforms and perform finite element and tolerance analyses to validate designs. ### Staff Mechanical Engineer @ Beckman Coulter Jan 2017 – Jan 2019 | Miami/Fort Lauderdale Area • Led teams spanning Engineering, Manufacturing, Procurement, Quality, and Service departments to identify root causes and resolve most common reliability issues saving $10 million/year and reducing failures by over 75%. ### Senior Mechanical Engineer @ Beckman Coulter Jan 2013 – Jan 2017 ## Education ### Master of Science in Aerospace Engineering; Computational Fluid Dynamics/Systems Design and Optimization Georgia Institute of Technology ### Bachelor of Science in Aerospace Engineering University of Florida ## Contact & Social - LinkedIn: https://linkedin.com/in/marcogonzalez2015 --- Source: https://flows.cv/marcogonzalez JSON Resume: https://flows.cv/marcogonzalez/resume.json Last updated: 2026-03-22
