About me

I am Theodore Valerio.Senior full stack developer. Architecture, delivery, and cloud-backed systems.

33 years old

15 years building software

M.S. Computer Science

AWS · EC2, S3, RDS

Over the past 15 years I have owned products end to end: architecture decisions, mentoring other engineers, scoping with stakeholders, and shipping systems that have to hold up in production. I have also taught at the university level, sharing what I have learned with up-and-coming developers.

Day to day I work across Laravel backends, React front ends, Shopify apps and Liquid storefronts, and the ops layer around shipping, pricing, and migrations. I deploy and run those systems on AWS with EC2, Elastic Beanstalk, S3, and RDS, and I stay close when reliability or performance needs attention.

Whether bridging design and development or chasing a bug that will not quit, I approach each task with care and curiosity. Static typing is welcome. Details are not optional.

Highlights

Engineering work that tends to stick

Shopify apps and storefronts, cloud deployments, reliability work, and the leadership side of getting systems shipped.

Platform & Integration Engineering

  • Shopify custom apps: Admin API integrations, webhooks, and order/product sync flows
  • Liquid themes and storefront work for store UX that still has to behave under real traffic
  • Laravel + WooCommerce bridge: syncing logic between WooCommerce and Laravel platforms
  • Firebase integration: newsletter processing, metadata tagging, Firestore + Cloud Storage

eCommerce Ops Engineering

  • Shopify store migrations with fallback strategies for shipping and business logic
  • Shipping label automation wired to Shopify orders and multi-platform fulfillment
  • Pricing rules and promotional campaign rollouts across Shopify catalogs
  • Dynamic shipping and coupon-driven cart logic where the edge cases actually live

Cloud & Reliability

  • Application deployments on AWS EC2 and Elastic Beanstalk for production workloads
  • S3 for asset and file storage, RDS for relational data behind Laravel and Node services
  • CI/CD pipelines into production so releases stay repeatable instead of hand-rolled
  • Production incident response, performance tuning, and reliability work when systems misbehave
  • Background processing with Laravel queue jobs, Supervisor workers, and cron

Leadership & Delivery

  • End-to-end architecture ownership from scoping and estimates through launch
  • Mentored engineers and aligned technical decisions with product and business goals
  • Stakeholder communication on delivery risk, trade-offs, and what actually ships
  • Multi-store and multi-tenant commerce systems under real traffic pressure

AI-Assisted Workflows

  • AI-assisted reply drafts inside SupportDesk, a Laravel ticketing system for customer service teams
  • Product review title generator for long review bodies and CSV import matching

SEO & Performance Optimization

  • Canonical tags, sitemap automation, and metadata controls for large-scale projects
  • Newsletter processors with Firebase + Puppeteer
  • React + Tailwind front ends with pagination, tag filters, and lazy loading
