Legacy PHP apps that crash, slow down, or that nobody wants to touch — I take them over and make them stable. 13+ years in Symfony, Laravel, Python and DevOps, with 6,900+ hours and 100% Job Success on Upwork. Most of my work starts the same way: an existing production system, an original developer who is gone, and a client who needs it to just work again. I read unfamiliar codebases fast, find the real cause instead of patching symptoms, and leave the system in a state the next person can maintain. WHAT I DO • Rescue & stabilize production apps — crashes, broken deploys, silent failures • Symfony & Laravel development and legacy upgrades (PHP 5 to 8, Symfony 2 to 6) • REST API development and third-party integrations • Performance tuning — Redis caching, Elasticsearch, query optimization • DevOps — Docker, AWS, DigitalOcean, Linux, CI/CD, RabbitMQ workers & schedulers • ERPNext / Frappe customization, deployment and integrations PROOF THAT CLIENTS KEEP ME My two longest engagements ran 1,463 hours and 1,431 hours with the same clients — one of them for over three years. Across 26 contracts I average around 260 hours per client, because the work does not come back broken. RESULTS I'VE DELIVERED • Migrated and dockerized a legacy Symfony 3 application into a reproducible local + production setup • Cut response times on a high-traffic directory platform with Redis caching and Elasticsearch tuning • Fixed multi-party WebRTC stability on iOS after months of intermittent dropouts • Resolved queue and worker failures in ERPNext following a server migration BEST FIT FOR • Existing systems that need rescuing, upgrading or scaling • Apps hitting performance or reliability limits • Long-term maintenance and ongoing development partnerships Not a fit for: brand-new WordPress sites, template theme work, or one-hour "just make it work" fixes with no access to the codebase. If you have a live system that needs someone who can step in, understand it, and make it solid — send me the details and I'll tell you honestly whether I'm the right person. Tech: PHP · Symfony · Laravel · Python · Frappe/ERPNext · Node.js · React · Vue · Angular · MySQL · Redis · Elasticsearch · RabbitMQ · Docker · AWS · DigitalOcean · Linux · REST API · CI/CD · WebRTC
