Need to customize WordPress or a CRM, connect APIs, or build functionality that standard plugins cannot handle? I create custom plugins, integrations, and business tools built around your requirements. Since 2007, I have helped companies extend existing platforms, connect disconnected systems, and develop custom backend solutions for non-standard technical requirements. WORDPRESS DEVELOPMENT I build and maintain WordPress solutions that go beyond standard themes and plugins: • Custom WordPress plugins • CRM and third-party API integrations • WooCommerce customizations • Custom forms, quizzes, and lead capture systems • User dashboards and reporting tools • PDF and document generation • Development and maintenance of existing custom code Clients usually contact me when a standard plugin cannot handle their requirements, an existing system needs significant customization, or several disconnected platforms need to exchange data reliably. CRM & CUSTOM BUSINESS SYSTEMS I work on the technical side of CRM platforms and internal business tools: • Customizing and extending existing CRM functionality • Building custom modules, dashboards, and internal tools • Integrating CRMs with websites, APIs, forms, telephony, and third-party services • Importing, exporting, transforming, and synchronizing data • Developing custom CRM and management systems for company-specific workflows • Maintaining and improving existing custom solutions My experience includes HubSpot, GoHighLevel, Kommo, JobNimbus, Airtable, and fully custom systems developed for individual business needs. API INTEGRATIONS & AUTOMATION I build reliable integrations using REST APIs, webhooks, scheduled synchronization, and custom middleware. This may include connecting CRMs, WordPress, WooCommerce, Twilio, Google Sheets, Airtable, payment services, marketing platforms, and internal company tools. For automation, I work with n8n, Make, Zapier, and custom PHP, JavaScript, or Python scripts when no-code tools are not flexible enough. I have completed 50 Upwork contracts while maintaining a 100% Job Success Score. Clients value my technical problem-solving, clear communication, responsiveness, and ability to find practical solutions to non-standard requirements. Tell me what you need to customize, connect, or build, and I will help you find the most practical technical solution.
