Built SelfGPT Studio, a local-first, self-hosted AI IDE that uses multiple LLM providers to generate, modify, debug, and run complete multi-file full-stack applications directly within a user's workspace. Designed an agent-based development workflow with specialized Builder, Debugger, Refactor, UX, Performance, Security, Test, and Documentation agents, enabling AI-assisted development across the software lifecycle. Architected the platform with Next.js 14, FastAPI, PostgreSQL, and local project storage, with support for multiple application stacks including React, Next.js, Node.js, MERN, Python, FastAPI, Flask, Django, and static web applications. Implemented project snapshots, file-level editing, diff comparison, dependency management, terminal execution, project export/import, stack-aware run profiles, and local application previews. Integrated multiple LLM providers including Groq, OpenAI, Mistral, DeepSeek, and Gemini, creating a flexible multi-model architecture for AI-powered software development.
