What I'm looking for

I seek senior engineering roles where I can build scalable, secure cloud-native systems, lead technical initiatives, mentor teams, and deliver production-grade blockchain and AI products.

I am a Senior Full-Stack Developer with 8+ years designing cloud-native, microservices-driven systems and full-stack applications. I specialize in blockchain tokenization, AI-driven platforms, and scalable architectures using React, TypeScript, Node.js, and Python.

At ZOTH I led development of a blockchain-based platform for tokenizing real-world assets, built event-driven microservices with Node.js, Python, GraphQL and Kafka, and implemented CI/CD on AWS EKS to ensure high availability and secure transaction processing. At Artisse I helped architect an AI photo-generation platform producing over 5 million images, optimized with serverless components and containerized deployments.

I mentor teams, adopt TDD, and apply observability tools to maintain performance and reliability. I seek to drive product-first engineering, deliver secure, compliant systems, and collaborate cross-functionally to create impactful user experiences.
