• Design and build high-correctness Rust services that sit on critical platform paths • Introduce Rust into areas where safety, determinism, and performance are essential • Own systems from architecture → implementation → rollout → operations • Make real decisions around concurrency, async boundaries, data integrity, and failure modes • Work across service boundaries in a polyglot environment (Rust alongside other stacks) • Collaborate with product, design, and frontend engineers to build systems that are technically sound and product-aware • Improve reliability, observability, and system behavior through design, not just patching • Mentor other engineers and raise the bar on system quality and ownership

• Identifying and eliminating backend performance bottlenecks by profiling PHP applications, analyzing MySQL/MariaDB query performance, and optimizing Memcached usage across Automattic’s products. • Building and improving performance observability—developing dashboards, instrumentation, and automated detection that surface regressions before they reach production, and give engineering teams clear, actionable data. • Partnering with product and platform engineers to review code and architecture through a performance lens, advocating for efficient database access patterns, caching strategies, and backend design decisions. • Raising the performance bar across engineering by documenting best practices, contributing to internal guidelines for PHP and database performance, and mentoring teams on how to write backend code that scales. • Proactively searching out performance issues and working to resolve them. • Deep dives on individual sites, working alongside support staff and engineers to address customer performance issues.

• Desarrollar soluciones tecnológicas para una de las empresas más grandes de México • Integrarse a un proyecto internacional de alto impacto

• Design, develop, and maintain full-stack applications using TypeScript, React.js, Node.js, Express, and Next.js. • Build and integrate RESTful APIs and microservices. • Work with both SQL and NoSQL databases to design schemas, optimize queries, and ensure high data integrity. • Collaborate closely with product, design, and engineering teams to deliver new features and improvements. • Implement best practices for code quality, testing, and performance. • Containerize and deploy services using Docker. • Use Git for version control and participate in code reviews. • Troubleshoot, debug, and optimize applications for maximum speed and scalability.
