You will get your CodeIgniter 2/3 app upgraded to CodeIgniter 4
Project details
If your application is running on CodeIgniter 2 or 3 and you want to upgrade it to CodeIgniter 4, I can handle the migration safely while preserving your existing functionality.
With 20+ years of experience in PHP development, I specialize in upgrading legacy applications and modernizing their structure without breaking critical features. CodeIgniter upgrades are not just version changes, they require proper handling of routing, controllers, models, libraries, and database compatibility.
This service is ideal if:
– You want to upgrade CodeIgniter 2 or 3 to CodeIgniter 4
– Your application is outdated and difficult to maintain
– You are facing compatibility or performance issues
– You need a stable and clean migration
What you can expect:
– Safe upgrade to CodeIgniter 4
– Updated structure (controllers, models, routes, helpers)
– Compatibility fixes and error resolution
– Improved performance and maintainability
I focus on delivering a smooth and reliable upgrade so your application continues to work without issues.
Please contact me before placing an order so I can review your application and suggest the best approach.

Job Success
Karachi, Pakistan - 10:01 am local time
I work with React, Next.js, Node.js, PHP, Laravel, CodeIgniter, WordPress, MySQL, PostgreSQL, MongoDB, API integrations, and automation. I help clients choose the right technology based on their goals, budget, timeline, and long-term plans instead of forcing every project into the same stack.
I can help you with:
– Custom web application development
– SaaS platform development
– MVP development from idea to launch
– Laravel, CodeIgniter, and custom PHP development
– React, Next.js, and modern frontend development
– Node.js backend development
– WordPress customization and custom development
– Legacy system upgrades and modernization
– Migration from older PHP systems to modern stacks
– API development and third-party integrations
– Workflow automation and internal business tools
– Database design, backend architecture, and admin panels
– Website speed, performance, and scalability improvements
– Security improvements, including SQL injection and XSS protection
– Technical planning, feature structuring, and long-term development guidance
Over the years, I’ve worked with startups, small businesses, agencies, and established companies on projects ranging from simple business websites to complex custom platforms. My focus is always on building solutions that are reliable, scalable, maintainable, and practical for the business.
I maintain a 100% Job Success Score on Upwork, built through clear communication, dependable delivery, and long-term client relationships.
I can handle the full process, including planning, wireframing, development, testing, deployment, and ongoing improvements. I can work independently, collaborate with your existing team, or guide developers when technical direction is needed.
If you are not technical, that’s completely fine. I regularly help clients understand what they need to build, what features matter most, what can wait, and how to avoid unnecessary complexity. I explain things in simple terms so you can make confident decisions without getting lost in technical details.
My process is simple. I first understand your goals and challenges, then suggest the best approach, build with regular updates, and help you launch and improve the product over time.
I’m not just here to write code. I’m here to help you build something that actually works for your business.
If you’re looking for a reliable full-stack developer who can guide you, communicate clearly, and deliver solid results, feel free to reach out and discuss your project.
