What I'm looking for

I'm seeking roles where I can drive technical direction, design scalable serverless architectures, mentor engineers, and apply AI to improve developer productivity and product outcomes.

I'm Vini, a Staff Software Engineer with 9+ years building reliable, scalable fintech and SaaS systems.

I design retention-focused architectures and internal metrics/observability dashboards, driving technical direction in partnership with CTOs and senior leadership.

My background includes ledger, payment integrations, loans, reconciliation platforms processing over $50M USD monthly, and full-stack work with TypeScript, NestJS, React, and serverless AWS services.

I'm passionate about thoughtful design (“solution before code”), mentoring engineers, and applying AI prompting and generative tools to improve developer productivity and product outcomes.
