AI App Deployment Specialist | APIs, Supabase & Payments

Supabase • Freelance

Sep 2026 - Present • 2 mos

I help clients prepare AI-powered web applications for launch by troubleshooting deployment problems, configuring integrations, and resolving technical issues that prevent applications from working correctly in production. My services cover Replit deployment, Base44 app launch support, AI web app deployment, custom domain configuration, environment variable setup, API troubleshooting, Supabase database connections, authentication, and payment integration. Where supported by the application's architecture, I can also help with GitHub workflows, Vercel deployment, production configuration, and application testing. I work with clients who encounter failed builds, blank screens, broken API requests, login problems, incorrect database permissions, and differences between preview and production environments. My approach is to investigate the cause, implement agreed fixes, and test the affected workflows. For applications using Supabase, I can help assess authentication configuration, database queries, Row Level Security policies, and access permissions. For payment-related projects, I can help implement or troubleshoot agreed Stripe checkout and webhook workflows using appropriate test credentials. I also support founders who need to connect their AI-generated application to external services or prepare an existing SaaS MVP for release. The scope depends on the hosting platform, code access, third-party requirements, and project complexity. My focus is on reliable integrations, appropriate security practices, clear documentation, and a practical handover that helps clients understand their application's deployment and technical setup.

SaaS MVP Developer | AI Integration & Full-Stack Apps

Integration Xperts • Freelance

Sep 2026 - Present • 2 mos

I help entrepreneurs, startup founders, and businesses develop web applications and SaaS MVPs that address practical business needs. My work includes application planning, feature development, database setup, user authentication, API integration, dashboard development, payment workflows, testing, and deployment preparation. I work with AI-assisted development platforms such as Base44, Replit, and Lovable, alongside relevant technologies and services such as Supabase, REST APIs, Stripe, React, JavaScript, and PostgreSQL when appropriate to the project. Application requirements may include user registration, protected dashboards, admin panels, customer portals, role-based permissions, data management, automated workflows, AI-powered functionality, and third-party integrations. I help define the required features and implement them according to the agreed scope. For existing products, I can help complete unfinished features, investigate technical problems, improve application structure, and prepare essential workflows for testing. For new projects, I focus on building the core functionality needed to validate a product idea before expanding into more complex features. My goal is to help businesses move from an idea or prototype to a functional application with clear requirements, appropriate technical implementation, and a practical handover. Larger projects involving multiple modules, complex integrations, or production infrastructure require a defined scope and project-specific estimate.

Vibe Coding Specialist | AI App Repair & Optimization

Optimize your Google Business Profile, dominate local SEO, and streamline customer engagement • Freelance

Jul 2026 - Present • 4 mos

I help clients fix, improve, and complete applications created with AI coding and vibe coding tools such as Base44, Replit, Lovable, Bolt.new, and Cursor, where the project and available source code support the required changes. AI-generated applications can develop broken components, runtime errors, inconsistent layouts, missing features, authentication failures, and database integration problems. My approach focuses on understanding the underlying issue and implementing a practical fix rather than repeatedly changing prompts without a clear diagnosis. My services include AI app debugging, vibe-coded app repair, code cleanup, code refactoring, feature development, responsive UI improvements, API integration, database troubleshooting, and deployment preparation. I can also work with relevant technologies such as React, JavaScript, Node.js, Supabase, PostgreSQL, and external APIs. For founders and businesses with an unfinished web app or SaaS MVP, I help identify what is working, what needs improvement, and which changes are necessary to achieve the agreed outcome. I prioritize functional workflows, appropriate data handling, maintainable code, and testing of the affected features. The goal is to help clients move beyond a promising AI-generated prototype toward a more reliable application that supports their business requirements and is better prepared for real users.
