PHP and CodeIgniter developer with 10+ years of experience building, improving, and maintaining custom CRM systems, SaaS platforms, admin dashboards, and business-critical web applications.
I help businesses replace spreadsheets, repetitive manual work, and disconnected tools with centralized web systems that improve data management, automate workflows, and support daily operations.
I work on both new and existing applications.
For new projects, I can design and develop complete systems from requirements and database planning through development, testing, deployment, and ongoing support.
For existing systems, I can understand the current codebase, fix difficult issues, improve performance, add new modules, modernize interfaces, optimize databases, and continue development without forcing an unnecessary rewrite.
I CAN HELP YOU WITH:
• Custom CRM and lead management systems
• SaaS and multi-user web applications
• Admin dashboards and reporting systems
• Membership, client, and employee portals
• Billing and payment management platforms
• Job and project management applications
• Workflow and business-process automation
• REST API and third-party integrations
• Legacy PHP and CodeIgniter application upgrades
• Bug fixing, performance optimization, and maintenance
• WordPress and WooCommerce customization
CORE TECHNICAL EXPERTISE:
• PHP and CodeIgniter 3/4
• MySQL database architecture and optimization
• JavaScript, jQuery, AJAX, HTML5, and CSS3
• Bootstrap and responsive user interfaces
• REST APIs, webhooks, and third-party services
• Role-based access control and user permissions
• SMTP email notifications and automated workflows
• Dashboards, reports, filters, and data visualization
• Payment gateway and subscription workflows
• Git, cPanel, Linux, and production deployment
FEATURED SAAS PROJECT — LEADBRIDGE
I designed and developed LeadBridge, a lead generation and outreach SaaS platform built with PHP, CodeIgniter, and MySQL.
It includes business lead discovery through Google Places API, automated lead qualification, personalized email campaigns, CRM pipeline management, user roles, dashboards, and reporting.
Building my own SaaS product has given me practical experience in product planning, user workflows, database design, business logic, maintainability, and real-world system usage—not only individual coding tasks.
OTHER SYSTEMS I HAVE DEVELOPED INCLUDE:
• Real estate CRM and property management platforms
• Gym membership and billing systems
• Medical practice and appointment systems
• Financial ledger and payment tracking applications
• Job and task management systems
• Educational and student portals
• Reporting and analytics dashboards
• Email campaign and business automation tools
Clients can expect clear communication, realistic timelines, structured and maintainable code, careful testing, and reliable support after delivery.
I work independently, take responsibility for the codebase, and focus on understanding the business process behind every feature. My goal is to deliver a system that works reliably today and remains practical to maintain and expand in the future.
Share your project requirements, existing application details, or current technical problem, and I will recommend a practical development approach.
