Paragon unleashes the ability to rent, buy, buy-now-pay-later, and rent-to-buy NFTs in one place. Paragon is able to facilitate permissionless and non-collateralized financing options across the NFT ecosystem.- I led the design and implementation of contracts, backend, and the overall architecture of our application. This encompasses everything from the marketplace, the "find the paragon" game, to the complete collection (seeker, minion, paragon).- The contracts successfully passed three audits conducted by Quantstamp.Feature Overview:Every user has a Smart Wallet (EIP4337) that streamlines operations such as buying, selling, renting, and "buy now pay later" without the need for collateral. This wallet allows for integrated use of NFTs for games, events, and more.- Technologies used: Rust with Actix framework, Typescript with Nestjs framework, Solidity (Foundry).

During my professional journey, I've specialized in:- Executing arbitrage between centralized and decentralized exchanges.- Implementing arbitrage among pairs within the same decentralized exchange.- Developing various strategies to capitalize on arbitrage opportunities.- Experience with MEV (Miner Extractable Value).- Working with liquidations in the decentralized finance space.

- Design and implementation of new features and refactor of existent ones for the company's core application. Technologies used: Typescript, ReactJs, Node.js, Express.js, Apollo GraphQL, Docker.- Participation in the design and implementation of the decomposition and transition from a single monolith app to several microservices interconnected through events and direct API calls (GraphQL, REST, Kafka).- Member of the team that designed and implemented the new CI/CD pipeline following the GitOps philosophy using AWS, Terraform, Kubernetes, Jenkins and ArgoCD.

WiniWallet was a mobile wallet based on Ethereum Smart Contract. The wallet user maintained an Ethereum account (Externally Owned Account) secretly on their mobile device. This account was established as the owner of the Smart Contract. The user's funds were stored in the Smart Contract. With that model, logic could be added to the wallet to improve both the user experience and its security. Transaction fees were paid with dai
