What I'm looking for

I'm looking for a remote backend or blockchain role where I can build secure, production-ready systems, work with TypeScript and distributed infrastructure, and solve practical business problems through reliable APIs, smart contracts, and cloud deployments.

I'm building CarVault, a multi-organization Hyperledger Fabric asset-management platform with TypeScript chaincodes, private data collections, RBAC, CouchDB audit trails, and Kubernetes deployment. I designed its three-organization identity infrastructure and integrated REST APIs with PostgreSQL for real-time synchronization.

As a freelance Inventory Systems Developer for a retail business in Cancún, I redesigned an existing MySQL inventory and point-of-sale workflow without disrupting existing data. I extended the schema for fractional-unit sales and configurable discounts, then architected a containerized Node.js/Express backend for real-time transactions.

I've also built decentralized price-oracle and car-rental token platforms on Hyperledger Besu, using Solidity, Hardhat, OpenZeppelin, UUPS upgrades, access controls, validation, and audit trails. I focus on secure, reliable systems that align blockchain infrastructure with practical business processes.
