blockchain architect / senior engineer

Rafael Aguirre

Blockchain architecture, full-stack delivery, and systems built to hold up in production.

I work across EVM, Solana, backend platforms, mobile products, and cloud infrastructure, with an emphasis on reliability, architectural clarity, and shipping cleanly under real-world constraints.

What I work on most.

The overlap between architecture, shipping, and long-term maintainability is where I do my best work.

Smart contracts, backend services, platform infrastructure, typed abstractions, and the places where product ideas meet operational reality.

about me

I like hard systems problems, readable architecture, and products that actually ship.

I have spent the last several years working across blockchain architecture, backend engineering, mobile products, and cloud infrastructure. My strongest lane is the intersection of hands-on engineering and system design: translating ambiguous requirements into production-ready software.

Most of my recent work sits across EVM and Solana ecosystems, but the broader pattern is consistent: distributed applications, event-driven flows, platform reliability, and delivery standards that hold up after launch.

Blockchain architecture

Smart contracts, DApps, wallets, NFT systems, cross-chain flows, and production-grade Web3 integration.

Backend and distributed systems

Event-driven services, operator tooling, APIs, data pipelines, and resilient infrastructure behind product teams.

Platform and delivery leadership

CI/CD, SRE, Terraform, cloud architecture, client communication, and technical guidance from design through release.

experience

Built through client work, startups, and infrastructure-heavy teams.

The common thread is owning the technical path from idea to deployment, then staying close enough to operations to know whether the system is actually doing its job.
