What I'm looking for

I seek a senior engineering role where I can build scalable web and blockchain systems, work in a collaborative Agile team, and drive technical excellence and mentorship.

I am a Full-Stack Engineer with over a decade of experience designing, building, and scaling high-performance web and blockchain systems. I combine strong frontend expertise in React, Vue.js, and Angular with backend proficiency in Java (Spring Boot), Node.js, .NET, Golang, and Laravel to deliver reliable, maintainable solutions.

My work spans cloud-native architectures on AWS and Azure, containerization with Docker and Kubernetes, and CI/CD-driven deployments. I have hands-on experience integrating and developing blockchain solutions on Ethereum and Solana, emphasizing performance, security, and scalability while contributing measurable product improvements.

I collaborate closely with product, security, and accessibility teams, mentor colleagues, and participate in Agile processes to deliver customer-focused features—reducing manual booking errors by 30% and lowering failed interactions by 15% in recent roles.
