About me

I am a creative and technically adept Senior Full Stack & Blockchain Developer with extensive experience designing and building scalable web and blockchain applications. I am proficient in modern frontend and backend frameworks, smart contract development, decentralized applications, and cloud-based DevOps practices. I am passionate about delivering efficient, maintainable, and secure solutions while leveraging cutting-edge technologies in Web3, AI, and cloud ecosystems.

Throughout my career, I have designed and deployed multi-step agentic systems using LangChain and LlamaIndex to automate complex workflows. I have built RAG pipelines for knowledge retrieval and integration with AI-driven tools, and architected production-grade AI systems ensuring reliability, monitoring, and scalability. My experience includes developing smart contracts in Solidity and integrating blockchain-based backend services with AI modules.

As a Full Stack Developer, I have collaborated on enterprise-grade applications covering frontend, backend, and database layers. I leverage modern frameworks and libraries to improve performance, maintainability, and user experience. I develop custom modules, plugins, and integrations to meet client-specific requirements and deploy and maintain applications on cloud infrastructure such as AWS and containerized environments.

In my role as a Senior Full Stack Developer, I have built dynamic, user-centric web applications using React, Next.js, and Node.js, integrating with cloud services and databases. I design and implement RESTful and GraphQL APIs optimized for performance and security. I develop interactive dashboards, AI-powered tools, and data-driven interfaces for clients and personal projects. I implement CI/CD pipelines with GitHub Actions and Docker to streamline deployment processes and reduce downtime. Additionally, I integrate real-time data and automate workflows for Telegram bots, marketplaces, and AI platforms.

I am continuously developing frameworks for AI-based automated contract management and actively contribute to building and documenting open-source tools for blockchain testing and deployment. I have a strong interest in AI x Blockchain convergence, Zero-Knowledge Proofs, and DeFi systems. Currently, I am learning Arabic, German, and Spanish to explore linguistic AI design and cultural computing.
