Overview Top Rated Plus Developer | 19,000+ Upwork Hours | 160+ Projects Completed I help businesses build, fix, integrate, deploy, and scale web and mobile applications using Laravel, PHP, WordPress, Concrete5, modern front-end technologies, APIs, AWS, and CRM platforms including HubSpot and Salesforce. My work ranges from Laravel/PHP applications and WordPress development to mobile apps, API integrations, AWS deployment and server management, CRM automation, and complex third-party integrations. I can help with AWS EC2, Linux servers, application deployment, DNS/SSL, CloudFront/Cloudflare environments, MySQL, server troubleshooting, performance issues, and production application support. If you need an experienced developer to build a new application, develop a mobile app, integrate multiple platforms, deploy or troubleshoot an AWS environment, or take ownership of an existing system that needs fixing or extending, I can help. Laravel & PHP Development I can help with: • Laravel application development and maintenance • Custom PHP development • Existing/legacy PHP application troubleshooting • REST API development and integration • MySQL database design and optimization • Authentication and user-management systems • Background jobs, queues, scheduled tasks, and automation • Server-side debugging and performance issues • AWS/Linux application deployment and troubleshooting WordPress & Concrete CMS I work with both standard and highly customized CMS implementations, including: • Custom WordPress development • Plugin and theme customization • WooCommerce development and integrations • Existing WordPress troubleshooting • Performance and server-related issues • Concrete CMS / Concrete5 development • Custom packages, blocks, themes, and integrations • Legacy Concrete5 application maintenance and upgrades I have extensive experience working with existing systems where rebuilding everything from scratch isn't practical. API & Third-Party Integrations API integration is one of the main areas I work in. I can integrate your application with: • REST APIs • OAuth/API authentication • Payment gateways • Shipping and logistics APIs • CRM platforms • Marketing platforms • Webhooks • Lead-generation platforms • Custom internal APIs • Third-party SaaS applications I also handle the parts that are often overlooked: authentication/token refresh, field mapping, validation, logging, retries, duplicate prevention, error handling, and data synchronization. Salesforce & HubSpot I can help connect your website or application with Salesforce and HubSpot, including: • Website → Salesforce lead integration • Website → HubSpot contact/lead integration • Salesforce REST API integrations • Custom Salesforce/Apex REST endpoints • Web-to-Lead implementations • HubSpot forms and CRM integrations • HubSpot workflows and automation • Lead-source and attribution tracking • Custom field mapping • CRM data synchronization • Marketing automation integrations • Zapier and webhook-based workflows I understand both the development side and the marketing/CRM side of these integrations, which is particularly useful when troubleshooting lead flows and attribution problems. Front-End Development When a project requires front-end work, I can also handle: • React • JavaScript / TypeScript • HTML5 / CSS3 • Bootstrap • Material UI • Responsive interfaces • Existing front-end troubleshooting • Front-end/API integration Why clients hire me I have completed 160+ Upwork projects with more than 19,000 hours worked. A large portion of my work involves joining existing projects, understanding somebody else's codebase, identifying the actual problem, and implementing a practical solution without unnecessarily rebuilding the entire system. I am comfortable working directly with business owners, agencies, marketing teams, designers, developers, Salesforce teams, HubSpot teams, and other technical stakeholders. Whether you need someone for a small API integration, an urgent production issue, or ongoing development of a larger application, feel free to send me the project details.
