Polars developer in Argentina (UTC-3)

I'm a backend-focused software engineer who enjoys solving complex data and system architecture challenges. My core work spans building API services with Python (FastAPI) and TypeScript (NestJS), designing database schemas in PostgreSQL and Snowflake, and implementing data pipelines for processing at scale. While my strength is in backend development, I've gained substantial experience across the full stack. I regularly handle DevOps responsibilities including cloud server setup, application containerization with Docker and Docker Compose, CI/CD automation via GitHub Actions, configuring Nginx as a reverse proxy, and writing bash scripts for operational tasks. On the frontend side, I work with React, Next.js and TypeScript ecosystems, using tools like Tailwind CSS, React Query, Zustand, and Zod for type validation. My experience includes both product development and consulting environments, where I've worked directly embedded with client teams and led backend development. I value clean code, pragmatic solutions, and straightforward communication in technical teams.
