Sajood Ur R.
Full Stack Developer | AI Agents, SaaS & Blockchain Engineer
Most developers ship features. I build systems that stay stable under real usage. As a Full Stack Developer, I focus on performance, reliability, and clean architecture. I build SaaS platforms, agentic AI systems, and blockchain solutions that work in real-world production environments. I use blockchain only where it makes financial or technical sense and I bridge Web2 and Web3 so you get the benefits without unnecessary complexity. What I do: - Full-stack development: React.js, Next.js, Node.js, MongoDB - Build scalable SaaS applications and backend systems - Design and build agentic AI systems, RAG pipelines, and automation workflows - LLM integrations (OpenAI, Claude, custom) - API development and integration - Fix bugs, broken APIs, and system bottlenecks - Optimize performance: queries, APIs, load time - Blockchain integration when needed (Solidity, Ethers.js, Web3.js) - Fix blockchain integration issues and smart contract problems - AWS deployment, Docker, CI/CD Recent Impact: - Reduced API latency by 40–60% through query optimization and caching - Restored ~100% transaction reliability by fixing blockchain integrations - Improved production performance and UX under real user load If you need to: - Build a SaaS platform or AI-powered product - Design and ship agentic AI workflows - Integrate blockchain into an existing system - Fix something already live I can step in quickly, understand your stack, and get it working properly. Send me your repo or tech stack. I'll review it and give you clear recommendations on the best way forward.
