Project details
You will get your old, slow, or unsupported PHP or Symfony application upgraded to a modern, secure version — and made noticeably faster.
I'm a Top Rated Plus developer with 13+ years of experience and a 100% Job Success score. I've upgraded large-scale Symfony applications and optimized production systems, so I know how to modernize a legacy codebase without breaking what already works.
What you can expect:
• PHP 5 to 8 and Symfony 2 to 6 upgrades (and everything in between)
• Dependency and Doctrine modernization
• Performance gains with Redis caching, Elasticsearch, and query optimization
• A clear before-and-after summary so you can see the improvement
From a focused audit to a complete upgrade and performance overhaul, I'll leave your app faster, safer, and far easier to maintain.

Job Success
Tangail, Bangladesh - 3:10 am local time
With 13+ years of experience in PHP (Symfony, Laravel), ERPNext/Frappe, Python, and DevOps, I specialize in taking over existing systems that need stability, performance, and long-term maintainability — the projects other developers find too messy or risky to touch.
WHAT I DO BEST
• Rescue & stabilize production apps — fix crashes, bugs, and broken deployments
• Symfony & Laravel development, plus legacy upgrades (PHP 5→8, Symfony 2→6)
• ERPNext / Frappe customization, integrations, and deployment
• REST API development & third-party integrations
• Performance tuning with Redis, Elasticsearch, and query optimization
• DevOps: Docker, AWS, DigitalOcean, Linux, CI/CD, RabbitMQ queues & schedulers
RESULTS I'VE DELIVERED
• Upgraded large-scale Symfony apps to a modern, maintainable architecture
• Resolved queue & worker failures in ERPNext after server migration
• Cut response times using Redis caching and optimized Elasticsearch
• Built and stabilized real-time systems (WebRTC) across web and iOS
WHY CLIENTS KEEP ME LONG-TERM
• I read and understand unfamiliar codebases fast
• Clear, reliable communication and dependable delivery
• Focused on stable, scalable solutions — not quick patches that break later
BEST FIT FOR
• Existing systems that need rescuing, improving, or scaling
• Projects hitting performance or reliability limits
• Ongoing development and long-term maintenance partnerships
If you need a Symfony/Laravel expert, ERPNext consultant, API developer, or DevOps engineer who can step into a live system and make it solid — let's talk.
