Harwinder Singh

Harwinder Singh operates as a solo freelance developer based in Dera Bassi, India, working remotely with businesses and agencies in the USA, UK, Canada, Australia and New Zealand. Active since 2012, the practice focuses on clients who need PHP, WordPress, Laravel, Twilio and AI-integration work carried out reliably, often after prior experiences with developers who missed scope or went unresponsive. Work spans WooCommerce stores, Laravel-based APIs for healthcare platforms handling patient records, and Twilio Flex contact centre setups supporting multiple concurrent agents. Services listed include WordPress development (hand-coded themes and custom plugins rather than page-builder output), PHP and Laravel development, Twilio development covering SMS, voice, Flex and Studio, and AI integration using OpenAI and Claude APIs connected into existing business systems. Additional listed capabilities cover custom software development, e-commerce development, mobile app development, and UX/UI and web design. The technical stack includes PHP 8, MySQL, REST APIs, React JS, Node.js, WooCommerce, Stripe and AWS. Working methods described include daily written progress updates, 4-6 hours of overlap with US and UK working hours, code written to PSR standards with inline documentation for handover to other developers, pre-delivery testing for edge cases and security issues, and 30 days of post-launch support included without a separate contract. Billing is structured around development time only, without account management or agency markup layered into invoices.
