What I'm looking for

I seek a hands-on engineering role where I can build AI-enabled web products, work with modern stacks, and contribute to efficient, user-focused systems with opportunities for growth.

I am a full-stack software engineer specializing in AI-driven web applications and blockchain integrations, with hands-on experience building production-ready systems and client-facing interfaces.

During a software engineering internship I designed a Vue.js frontend that improved customer retention and implemented backend components for stable TCP/IP connectivity between PLC and PC systems, while maintaining ROS services and YAML pipelines.

In project work I built a blockchain-backed audit and certification system integrating MasChain REST APIs and developed React interfaces for issuance and verification, and I delivered a full-stack AI cooking app that combines Roboflow computer vision, OpenAI pipelines, JWT authentication, Prisma and PostgreSQL for persistent user data.

I bring a results-driven mindset, strong practical experience with modern web stacks and AI integration, and a focus on delivering performant, user-centered products that improve efficiency and traceability.
