Ernesto Almario

I’m a Senior Full-Stack & Smart Contract Engineer with a multidisciplinary background spanning Web3 architecture, game technology, and technical project management. I build secure, scalable blockchain solutions and high-performance applications, grounded in end-to-end delivery—from design to deployment and automated testing.

In my current work as a Platform Engineer Manager, I led the architecture, development, and operations of the XGame Web3 Gaming Platform. I manage cross-functional teams (software engineers, game developers, UI/UX) while staying hands-on across the full stack, architecting hybrid systems that connect blockchain infrastructure with real-time application services.

Previously, I served as a Sr. Software Engineer where I architected scalable systems and delivered high-performance frontends with Angular, React, and Next.js. I also built secure backend infrastructure using Fastify (Node.js), engineered data models across MongoDB and MySQL, and ensured reliability with rigorous unit testing, manual debugging workflows, and TDD practices.

I’m especially strong in blockchain engineering: I develop Rust-based smart contracts using Ink! for Substrate environments, integrate Polkadot API for wallet connectivity and on-chain interactions, and validate security/performance through testing and gas optimization. I also translate technical risk and roadmap milestones into actionable decisions for executives, aligning engineering deliverables with business objectives and product-market fit.
