What I'm looking for

I’m looking to build scalable backend and Web3/DeFi products—designing robust APIs, smart contracts, and real-time monitoring—so I can ship high-impact features in a collaborative engineering environment.

I’m a software engineer focused on backend and Web3/DeFi, with hands-on experience spanning smart contract development and production-grade API systems. I’ve worked across decentralized trading and finance, monitoring and alerting pipelines, and scalable application architecture.

In my current full-time role as a Fullstack Web3 Developer, I’m a core contributor to decentralized trading protocols covering perpetuals, spot swaps, and multi-wallet asset management. I built and scaled a platform to $700M+ in cumulative trading volume and designed an AI-driven trade suggestion module that generates autonomous perpetual trading recommendations from live market data.

I also develop the backend infrastructure that powers these systems—building APIs for user management, incentives, trading proxies, event tracking, and AI endpoints on AWS using AWS CDK. Alongside this, I’ve contributed to additional DeFi protocol features such as token swaps, social trading mechanics, and embedded wallet onboarding.

Before shifting deeper into blockchain, I built a strong foundation through 4 years of Unity development, contributing to multiplayer projects and shipping games with 10M+ downloads. I bring that engineering mindset—scalability, maintainability, and clean separation of concerns—into everything from N-tier CRM systems to EVM monitoring that detects depeg risks and arbitrage opportunities.
