I’m a software engineer focused on backend systems, fintech, and blockchain.

I build production-ready software across the stack—from backend APIs and PostgreSQL databases to smart contracts and blockchain integrations.

My experience includes:
• Building algorithmic trading platforms and automated trading infrastructure
• Developing backend systems with Node.js, TypeScript, PostgreSQL, and Redis
• Building smart contracts and DeFi applications on Ethereum
• Developing blockchain applications on Solana
• Integrating cryptocurrency exchanges, wallets, and blockchain protocols
• Designing and deploying cloud-based production systems

I enjoy working on technically challenging problems, especially where software, financial systems, and blockchain intersect.

Currently, I’m looking for opportunities to work with startups, fintech companies, and teams building products in Web3, financial infrastructure, and backend-heavy applications.
