What I'm looking for

I seek roles that let me build scalable web and AI systems, work with cross-functional teams, and grow in full-stack, blockchain, or ML engineering.

I am a computer science graduate with hands-on experience in full-stack web development, blockchain applications, and AI model training. I have built responsive WordPress sites, decentralized NFT marketplaces, and an AI-powered travel planner while contributing to LLM fine-tuning and data annotation efforts.

I focus on producing reliable, production-ready solutions and improving model and product performance through careful testing, analytics, and iteration. I bring strong foundations in data structures, algorithms, OOP, databases, and practical experience with Java, Python, Solidity, React, Firebase, and cloud/datastore tools.
