As a Senior Full Stack Developer, I specialize in crafting innovative solutions that span web, mobile, and blockchain platforms, leveraging a comprehensive blend of front-end, back-end, AI, NLP, and decentralized technologies. With expertise in modern front-end frameworks such as React, Angular, and Vue.js, I create dynamic and responsive user interfaces that enhance user engagement and accessibility. My proficiency extends to mobile application development using React Native, ensuring consistent and high-quality experiences across iOS and Android devices.


On the back-end, I bring extensive experience with Java, Kotlin, Node.js, and microservices architecture, enabling the development of scalable and efficient systems. I am adept at managing both SQL and NoSQL databases, including MongoDB and GraphQL, ensuring robust data management and seamless integration with RESTful APIs and GraphQL interfaces. My blockchain expertise includes designing and deploying smart contracts, building decentralized applications (dApps), and working with platforms like Ethereum, Solidity, and Web3.js, delivering secure and scalable solutions for decentralized ecosystems.


Additionally, I have hands-on experience with Twilio for VoIP solutions and FreeSWITCH, allowing for versatile and scalable communication systems. My AI and NLP expertise helps create intelligent systems, driving automation and enhancing user experiences. Passionate about leveraging cutting-edge technologies and collaborating within cross-functional teams, I focus on delivering maintainable and efficient code. My experience with CI/CD pipelines, using Jenkins, Docker, and Kubernetes, complements my cloud expertise in AWS and Google Cloud Platform, enabling me to deliver comprehensive and reliable full-stack and blockchain-based solutions.
