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

Integrated systems rarely break on the first successful API call. They break three weeks later: a failed Shopify webhook, an ERP order that never synced, a CRM contact missing from the pipeline, or POS inventory that no longer matches the store. I build and fix the middleware/API layer behind those systems. My strongest work is around Shopify, ERP, CRM, POS, and Laravel-based backend systems where product data, orders, inventory, customers, payments, and reporting all need to stay aligned. What I usually handle: - Shopify / Shopify Plus integrations and custom commerce workflows - ERP and CRM syncs: Acumatica, Salesforce, Zoho, HubSpot, SAP-style systems - POS and inventory workflows: Clover, store operations, loyalty, order flows - Laravel/PHP middleware, APIs, webhooks, queues, cron jobs, retries, and logs - Admin dashboards, reporting panels, and operational data models - Production debugging where the issue is hidden across multiple systems Relevant background: - Built and supported systems handling 24k+ products, 3M+ users, and 2,000+ locations - Led technical delivery across teams of 20+ - Worked across Shopify, Shopify Plus, Magento, BigCommerce, Acumatica, Salesforce, Zoho, Clover POS, Laravel, REST/GraphQL APIs, PostgreSQL, MySQL, AWS, Firebase, and payment systems I also take on SaaS MVPs and React Native app work when the project depends on backend architecture, integrations, subscriptions, analytics, or production stability. If your store, ERP, CRM, POS, or internal dashboard is held together by fragile syncs and unclear data flow, I can help trace where it breaks and make the system reliable.
