Background
About
I'm a hands-on blockchain and full-stack engineer — I architect systems, write production-oriented code, and take ownership of technical implementation from smart contracts through backend infrastructure.
My work sits where decentralized systems meet real-world finance and AI: DeFi, digital-asset platforms, blockchain intelligence, and AI infrastructure.
Building DecentraMind Labs while leading development at SureStack has expanded my experience across hands-on engineering, architecture decisions, implementation review, technical coordination, and product development — without taking me away from the code.
