Software Engineer Seicho
I develop and evolve full-stack solutions across multiple products and business domains using Next.js, NestJS, and TypeScript. I work on both new development and established systems, analyzing legacy codebases, troubleshooting issues, refactoring components, and implementing frontend, backend, and business-logic features.
I developed a raffle platform almost end-to-end, from requirements through a client demo, and gained deployment experience with Fly.io. I also contributed to a proof of concept for generating and processing high volumes of professional fee receipts, handling millions of records in approximately two hours.
I maintain integrations and automation for tax-related workflows involving Chilean tax authority (SII) systems, document processing, invoicing, and expense reporting. I work directly with clients on requirements gathering, product demonstrations, feature validation, and technical decisions.
