Building intelligent, scalable web applications is my specialty. As a Full Stack Developer, I bridge the gap between robust backends and dynamic frontends, along with having experience on integrating AI Agents into modern software architectures. Whether you need a complex SaaS platform, an AI-powered automation/scraper tool, or a high-performance API, I deliver clean, efficient, and maintainable code. My Core Tech Stack 🤖 AI & Backend: Python, FastAPI, AI Agents (LLM integration, LangChain, etc.), Node.js 🖥️ Frontend: React.js, JavaScript/TypeScript, HTML5, CSS3, TailwindCSS 🚀 Cloud & DevOps: AWS (EC2, Lambda, S3), Docker, Git/Github, DigitalOcean, Redis 🔌 Others: Stripe Integration, Vercel, API limits and security measures. 🍒 The Cherry on Top: Full Support after Delivery. That's right, no additional cost. If anything breaks or you need minor changes, I will do it for free, ASAP.
