I work across the full stack using React, Next.js, TypeScript, Tailwind CSS, Node.js, Express, PostgreSQL, MongoDB, Supabase, Prisma, Drizzle, and modern AI APIs like OpenAI / ChatGPT, Gemini, and other LLM APIs. What I can help you build: ⢠SaaS MVPs from idea to working product ⢠Custom web apps with authentication, dashboards, roles, and admin panels ⢠AI integrations using OpenAI, ChatGPT, Gemini, and third-party LLM APIs ⢠Agentic AI workflows, AI assistants, automation tools, and internal AI systems ⢠AI chatbots, content generation tools, and data-processing workflows ⢠Backend APIs, database design, and third-party API integrations ⢠Figma to React / Next.js frontends ⢠Business websites, landing pages, CMS features, and performance improvements ⢠Bug fixes, feature development, and improvements for existing apps I focus on practical development, not overcomplicated systems.
