Message

At G4F, I develop and maintain full-stack web applications that retrieve and process documents from other systems, working with large volumes of data. I also integrate applications with different databases and SharePoint.

I maintain a data-indexing system built with Apache Solr. My work at G4F uses Node.js, TypeScript, React, and PostgreSQL.

Previously at Bcodex, I participated in refactoring a critical asynchronous payments flow and improved query latency by 40% on the company's main product. I also worked on test-pipeline improvements and refactored a critical KYC flow; earlier, I developed MVPs and reusable design-system components at GoLedger.
