I build operational web platforms, SaaS systems, dashboards, and AI-assisted applications with a strong focus on maintainable architecture, workflow-driven development, and rapid execution. Over the last several months, much of my work has involved AI-assisted development workflows using tools like ChatGPT, Claude, Cursor, Codex, and Lovable to accelerate: - frontend development - backend scaffolding - APIs/integrations - debugging and refactoring - deployment workflows while still keeping projects clean, production-oriented, and maintainable. My experience includes: - operational SaaS platforms - admin dashboards - CRM/HRM systems - logistics & dispatcher systems - role-based multi-user applications - booking/workflow platforms - AI-assisted business tools - realtime operational systems I’m comfortable handling: - frontend + backend development - API integrations - database structure - workflow/business logic - dashboards/admin panels - deployment and stabilization - MVP → production transitions Tech stack includes: - Laravel / PHP - Node.js - PostgreSQL / MySQL - WordPress - REST APIs & third-party integrations - Vercel / cloud deployment workflows I especially enjoy working on: - operational platforms - workflow-heavy systems - AI-assisted/vibe-coded products - partially built applications needing stabilization and structure I value long-term client relationships, clear communication, and reliable execution — which is reflected in my long-standing Upwork history and client feedback. I move fast, communicate clearly, and focus on building systems that are practical, maintainable, and ready for real-world use.
