Andrei

AI App Debugging Specialist

Self-Employed / Freelancer • Lavoratore autonomo

Jun 2025 - Present • 1 yr 4 mos

Provided specialized debugging and repair services for Lovable AI, Base44, and Replit projects that were stuck, broken, or failing to deploy correctly. Clients came in with a wide range of issues, from blank screens after deployment to broken Supabase connections, failed Stripe integrations, and authentication flows that stopped working after AI-generated code changes. Diagnosed each issue by reviewing project access, error logs, console output, and Supabase dashboards to pinpoint root causes rather than applying temporary patches. Common fixes included resolving Row Level Security (RLS) policy errors in Supabase, correcting environment variable misconfigurations, repairing broken API integrations, and untangling conflicting code generated across multiple AI-assisted editing sessions. Rebuilt or refactored sections of SaaS MVPs where the underlying code had become unstable, ensuring the final product was clean, scalable, and ready for continued development or investor demos. Restored broken Stripe payment flows, fixed subscription billing logic, and repaired user authentication and role-based access systems that had been misconfigured during initial builds. Worked under time pressure on many projects, since clients often reached out only after a deployment deadline was missed or a demo was at risk. Delivered same-day or next-day fixes for smaller issues and multi-day turnarounds for larger, multi-feature rebuilds. Provided clear documentation of what was broken and how it was resolved, along with recommendations to prevent similar issues going forward, helping non-technical founders understand their own products better. Maintained a personal tracking system for recurring bug patterns across Lovable and Base44 projects, which helped speed up diagnosis time for similar issues on future client work and improved overall turnaround consistency.

Automation & Bot Developer

Independent • Freelance

Jul 2024 - Present • 2 yrs 3 mos

Worked as an automation and bot development specialist, building custom AI-powered bots for Twitter/X, Telegram, and other social platforms using n8n workflows and Grok AI integration. Focused on connecting AI agents to real-time platforms so clients could automate content posting, audience engagement, and customer interactions at scale. Designed and deployed n8n automation pipelines that connected Twitter/X and Telegram bots to Grok AI for generating context-aware responses, scheduling posts, and monitoring engagement metrics. Built workflows that handled webhook triggers, API rate limits, and error handling to keep bots running reliably without constant manual intervention from clients. Integrated third-party APIs and services into automation flows, including social platform APIs, webhook-based triggers, and custom scripts for data processing between platforms. Configured MCP servers where needed to connect AI agents with external tools, databases, and local scripts, extending bot functionality beyond simple message responses into more complex, multi-step automated tasks. Worked with clients ranging from solo content creators to small marketing teams, translating their engagement goals into functioning automation systems. Provided ongoing support after initial deployment, including monitoring bot performance, adjusting Grok AI prompt logic for better response quality, and scaling workflows as client audiences and platform usage grew. Delivered clear setup documentation so clients could manage and adjust their own automation systems independently after handover, reducing long-term dependency while maintaining a strong track record for follow-up work and referrals. Regularly tested new n8n nodes and AI model updates to keep automation pipelines efficient, adapting workflows quickly whenever platform APIs changed to avoid downtime for client-facing bots.

AI Agent & Full Stack Developer

Contractor Independence Marketing • Freelance

Mar 2023 - Present • 3 yrs 7 mos

Worked as an AI application developer building full stack SaaS platforms using Lovable, Base44, and Claude Code, with a strong focus on agentic AI workflows and Model Context Protocol (MCP) integration. This role expanded on standard AI SaaS builds by incorporating more advanced AI-driven functionality directly into client applications. Built AI chat assistants, document processing tools, and automated workflow features into client SaaS products, connecting frontend interfaces to backend AI logic powered by Claude and OpenAI models. Used Claude Code agentic workflows to accelerate development, generate and refine backend logic, and connect applications to local scripts, databases, and external tools through MCP servers. Handled complex integrations between AI models and traditional SaaS infrastructure, including Supabase for data storage, Stripe for payments, and various third-party APIs requested by clients. Focused heavily on clean architecture so that AI-generated code remained maintainable and scalable as products grew, rather than becoming difficult to extend after initial launch. Collaborated closely with non-technical founders to translate business ideas into technical specifications, then executed builds independently with regular check-ins and demos. Delivered several production-ready AI SaaS platforms that moved from concept to live deployment within days, including full ownership handover of code, GitHub repositories, and hosting accounts. Provided guidance to clients on managing their own AI API keys, understanding usage costs, and scaling their applications post-launch, positioning them for long-term success beyond the initial build engagement. Continuously researched emerging AI development tools and workflow patterns to stay ahead of platform updates, ensuring client projects always used current best practices rather than outdated integration methods.
