Felipe Bueno

Fullstack software engineer at Pilgrims Consulting, delivering end-to-end products for external clients with TypeScript (NestJS, Node.js, React/Next.js) and Python (Django, FastAPI, Airflow). My work spans backend APIs, database performance, system integrations and AWS.

I diagnosed and fixed a quotation platform handling 40,000+ quotations and 1M+ line items, reducing response time from 92 seconds to approximately 0.8 seconds, screen abandonment from 88% to 10%, and performance-related support tickets by 95%. The work addressed N+1 queries, missing indexes, inefficient filters, pagination and Redis caching.

I built 60+ Airflow DAGs and refactored 140+ existing pipelines across SAP, TOTVS and Winthor ERP sources. I also built a Python freight ETL covering 2,860 routes and 20,020 validated rows with 70 automated tests, and implemented database-level locking to keep dock-slot bookings within daily volume limits under concurrency.

I designed and rolled out an SDLC model for a 4-developer team, including code review, TDD, spec-driven development and PR-gated CI/CD. Personal projects include stealth-reader, a Rust terminal reader with startup reduced from 339ms to 0.9ms, and Bookclubinho, a Next.js/FastAPI platform with real-time chat and secure authentication.

Based in Curitiba, Brazil (UTC-3), and open to international remote opportunities and relocation in software engineering, fullstack and backend development. Portuguese: native; English: advanced (C1); Spanish: professional working proficiency.
