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

You don't need someone to write code. You need someone who understands your business problem and delivers a backend that doesn't need to be rebuilt in a year. 6+ years working in PHP and Laravel across SaaS platforms, e-commerce systems, and custom WordPress backends. I've shipped 450+ projects and I maintain open-source Laravel packages actively used by other developers - that's not a line on a resume, you can read the code on GitHub before you hire me. What I actually work on: ✓ Laravel SaaS backends - multi-tenant architecture, billing integrations (Stripe, PayPal), job queues, real-time features with Reverb or Pusher ✓ RESTful and headless API development - versioning, authentication (Sanctum, Passport, JWT), third-party integrations, and passive contract monitoring so integrations don't silently break ✓ WordPress - custom plugins, hook architecture, WooCommerce extensions, REST API bridges between WP and Laravel systems ✓ Performance and refactoring - I regularly take over legacy Laravel codebases, add test coverage, resolve N+1 issues, and modernize to current standards without breaking production ✓ E-commerce - order pipelines, multi-channel inventory (Shopify, WooCommerce, Amazon, Etsy), payment gateway integrations A few things I've shipped publicly: Built a multi-channel notification engine for Laravel 12 with parallel dispatching and smart routing. A static analysis tool that catches dangerous migrations before they hit production. A passive API contract monitor that detects breaking changes in third-party REST APIs using probabilistic inference. These aren't portfolio pieces - they're tools other developers use. On working with AI: Yes, I use AI tools in my workflow. The difference between a developer who uses AI well and one who doesn't is knowing what to verify, what to question, and what to never let near production without review. My open-source work exists partly because I kept running into problems that AI-generated boilerplate can't solve. Who I work well with: Founders and technical leads who know what they want to build but need someone who can own the backend without constant hand-holding. If you have a spec, I'll ask the right questions and deliver clean, documented code. If you have a problem, I'll figure out the architecture. Available for fixed-price projects and ongoing contracts. Response time is fast - usually within 10 minutes
