Sep 2026 - Present • 1 mo

I help entrepreneurs, startups, agencies, and established businesses turn operational challenges into functional web applications and digital products using AI-assisted development and no-code or low-code platforms. My work covers business web apps, SaaS MVPs, CRM systems, client portals, admin dashboards, internal tools, and AI-powered applications. I use platforms such as Base44, Lovable, Replit, and Bolt to accelerate development while focusing on the features and workflows each project requires. My areas of work include: • AI web app development and vibe coding • SaaS MVP development and product prototyping • CRM and business management applications • Client portals and role-based dashboards • Database design and Supabase integration • API integration and workflow automation • User authentication and access management • Stripe payment integration • Existing app customization and bug fixing • Testing, deployment, and ongoing improvements I focus on solving practical business problems, including manual processes, disconnected data, inefficient customer management, and product ideas that have not yet become usable applications. My process starts with understanding the business objective, defining the essential features, and selecting an appropriate technical approach. I then build or improve the application, test the agreed workflows, and prepare it for the next stage of use. For larger projects, I can help plan an MVP, define user roles, organize database structures, integrate third-party services, and develop features in stages. My goal is to help clients turn ideas into useful digital products with clear functionality and a foundation that can be improved as their needs grow.

Apr 2026 - Present • 6 mos

I help businesses and developers diagnose, repair, and improve AI-generated web applications built with Base44, Lovable, Replit, Bolt, and other compatible vibe coding tools. AI-generated apps can develop broken features, authentication errors, database problems, failed integrations, and deployment issues. I focus on identifying the underlying cause and fixing the affected functionality instead of applying temporary workarounds. Areas of expertise include: • Base44 bug fixing and app troubleshooting • Lovable AI debugging and feature repair • Supabase database errors and query issues • Authentication, user sessions, and access permissions • API integration errors and webhook troubleshooting • Stripe checkout and payment workflow issues • React frontend and responsive UI bugs • Application testing and performance improvements • Deployment troubleshooting and configuration • Backend logic and database integration I review the available project information, reproduce the reported issue where possible, identify the likely cause, and implement and test an agreed fix. For more complex problems, I assess the existing application before recommending whether repair, refactoring, or rebuilding is the better option. My objective is to help clients recover working functionality, reduce recurring errors, and prepare their applications for dependable use. I also support feature completion, Supabase integration, app improvements, and deployment preparation for AI-built MVPs and SaaS products.
