What I'm looking for

I seek roles building scalable AI-enabled platforms and integrations, with strong engineering teams, CI/CD practices, and opportunities to optimize systems and reduce costs.

I’m a Full Stack Developer and AI Engineer with 6+ years of experience transforming ambitious ideas into production-ready applications. My core expertise covers React.js, Node.js, FastAPI, Python, PHP, and PostgreSQL, along with hands-on work in AI integration, automation, and blockchain development on both Ethereum and Solana.

I’ve led and contributed to projects in fintech, e-commerce, real estate, and AI-driven analytics - building everything from trading bots and chat automation systems to scalable backends and decentralized apps. Every project I take on is guided by my belief that innovation and discipline can turn the impossible into reality.

I’m deeply motivated by learning, problem-solving, and creating technology that empowers people and businesses. My work reflects a balance of logic and creativity - always striving for performance, clarity, and long-term impact.
