CV

I was hired by the VP of engineering. I’m working as an individual contributor in data infrastructure and backend projects.

• REST API maintenance in blockchain’s domain endpoints while decommissioning some parts of legacy code and developing new others
• I contributed to the blockchain’s pipeline development not only by adding new pipelines or features but also by adding automated tests, decommissioning, and refactoring code to reduce technical debt and increase maintainability
• I rebuilt crawlers to fetch blockchain data across the web for multiple chains, with means to fix outstanding issues while increasing performance and maintainability. Additional features like proxying + exponential backoff were implemented to avoid blocklisting
• I built ETL programs to move data from structured databases to object storage with minimal resource usage, while inserting GBs worth of data in minutes
• EVM data pipelines implementation using Substreams with Rust and Go, consuming TBs of data in a matter of hours while keeping the resource usage to a minimum
• I customized open souce software to fit the needs of our company, such as creating forks to add new features or fix bugs that don’t need upstream intervention. Notable examples are: Ethereum ABI decoding project to support lower Node versions, and Substreams file sink project to support binary file writing in Apache Parquet format and proper upload to cloud object storage

I worked in a contract as a software engineer for the service team, but mainly worked as a lead infrastructure engineer cross-organization.

• I set up engineering documentation for infrastructure
• I made the architectural planning and execution for cloud infrastructure across the organization, from environments to services, so that applications and services perform well and developers can be productive in this environment
• I made the architecture planning across applications that use the organization’s cloud infrastructure, setting up high standards to achieve scalability and reduce technical debt
• I made some Continuous Integration improvements by adding processes to achieve better code quality and setting a high bar on application and infrastructure code development, improving code quality by 40% with fewer reviews and developer comments
• I implemented Continuous Deployment processes by setting up fast-moving pipelines that communicate with cloud resources so applications are always deployed and available for developers and customers. It improved developer productivity by 63%, decreasing infrastructure costs since no manual deployment intervention is required
• Active contributor in back-end and infrastructure projects, with more than 80% accuracy on delivery estimates
• I mentored software engineers on hard and soft skills to give them room to grow in the company and their careers
