I help startups and businesses build SaaS platforms, API integrations, automation systems, and custom web applications that scale from MVP to production. Most of my work involves developing SaaS products, multi-tenant systems, admin dashboards, and APIs where performance, structure, and long-term scalability matter. I focus on building systems that are stable, maintainable, and ready for real users, not quick fixes or temporary solutions. Clients usually come to me when they need to: • Build a custom web application from scratch • Develop an MVP to validate and launch a product • Create a SaaS platform with user roles, subscriptions, and scalable architecture • Build admin dashboards or internal business tools • Develop backend APIs for web or mobile applications • Replace plugin-based setups with clean, structured systems I work across both frontend and backend, keeping application logic, database structure, and user experience aligned. Whether it’s a landing page supporting a product or a full SaaS platform with complex workflows, the goal is always to build something reliable and easy to extend. In addition to core development, I integrate AI and automation into real systems where they add practical value. This includes AI-powered features, workflow automation, API-based integrations, and business process automation using tools like n8n, Zapier, and custom backend logic — not isolated demos. I follow a structured development approach: clear requirements, clean code, realistic timelines, and transparent communication. The systems I build are designed to be understood, maintained, and improved over time. What I work on • Full-stack web applications and SaaS platforms • SaaS MVP development and multi-tenant systems • Backend development and REST API design • Admin panels, dashboards, and internal tools • Authentication, authorization, and secure systems • Payment gateway and third-party API integrations • Database design, optimization, and backend architecture • AI-powered features and automation workflows (n8n, APIs, business logic) Core Technologies • PHP (Laravel) • JavaScript (Vue.js, React, Next.js) • Python (AI & backend services) • Databases: MySQL, PostgreSQL • REST APIs, webhooks, third-party integrations Keywords Full-Stack Developer, SaaS Developer, SaaS Application Development, SaaS MVP Development, Multi-Tenant SaaS, Custom Web Application Developer, Backend Developer, Laravel Developer, PHP Developer, JavaScript Developer, Vue.js Developer, React Developer, API Development, REST API Development, Backend & Frontend Development, Admin Dashboard Development, Database Design, MySQL, PostgreSQL, Authentication & Authorization, Payment Gateway Integration, Third-Party API Integration, Internal Tools Development, Scalable Web Applications, AI Integration, AI Automation, Workflow Automation, API Automation, n8n, Zapier Integration, Make (Integromat), Business Process Automation, Clean Code, Secure Web Applications

Hello! I'm Qaisar Khan, a Google Apps Script specialist and Laravel developer with 4+ years of experience and 159+ completed projects on Upwork. I help businesses automate workflows, integrate systems, and build web applications that save time and reduce manual work. 🎯 **What I Do Best:** **Business Automation & Workflow Systems** I build end-to-end automation using Google Apps Script and Laravel — from CRM integrations (Jobber, Pipedrive, ActiveCampaign) to custom reporting dashboards, API pipelines, and AI-powered workflows. If your team is doing something manually that a system could handle, I can build that system. **Google Workspace & Apps Script** Custom Google Sheets dashboards, automated data pipelines, time-triggered workflows, third-party API integrations, and full Google Workspace automation. From simple scripts to complex multi-sheet systems. **PHP Laravel Development** Custom web applications, REST APIs, role-based portals, webhook handlers, and database-driven systems built with Laravel, MySQL, Vue.js, and Livewire. **API & System Integrations** Experienced connecting platforms like Jobber, ServiceTitan, Pipedrive, Podium, ActiveCampaign, Slack, JotForm, and AI APIs (Claude, Gemini) into unified automated workflows. --- ✅ 100% Job Success Score ✅ Top Rated Plus ✅ 159+ Projects Completed ✅ $60K+ Earned on Upwork --- My clients range from home service businesses needing field operations automation to SaaS founders needing custom integrations and solo entrepreneurs streamlining their Google Workspace. Let's talk about your project — message me and I'll respond within a few hours. --- **Key changes I made:** - Opens with results/outcomes not "dedicated expert" fluff - CRM/automation leads but Laravel and broad web dev stay visible - Dropped generic skills list, replaced with what you actually build - Your stats do the credibility work instead of empty claims - "Best Regards" closing removed — too formal for Upwork, clients want direct
