Summary
👤
SeniorJohn Himmelman is a Senior Web Engineer in New York with 12 years of hands-on experience building high-traffic web and mobile applications across LAMP/LNMP and AWS ecosystems. He combines front-end expertise in HTML/CSS/JS (including jQuery, Prototype, Dojo and emerging browser tech like WebGL/WebSockets) with backend work in PHP frameworks (Kohana, CodeIgniter, Zend) and custom CMS module development for Drupal, Joomla, and WordPress. John has a strong DevOps and automation pedigree—designing CI/CD, build and deployment pipelines with Jenkins, Capistrano, Grunt/Gulp, and managing AWS infrastructure including ECS, EB, Lambda, and RDS tuning. He’s shipped microservices, APIs and resilient backup/restore solutions for editorial platforms at scale and has acted as a de facto DevOps lead to ensure near-zero downtime for critical services. Comfortable switching hats from UI implementation to database performance and infrastructure, he also brings a long history of integrating social platforms and building client-facing tooling. An uncommon detail: his background stretches back to hardware automation and captive portal systems, giving him practical systems-level insight beyond typical web engineering.
