I’m Gunjan Basnet—a software developer and gas station owner in Keller, Texas. I build automation and integration solutions for POS systems, from parsing XML transactions to implementing loyalty servers (Gilbarco Passport protocol). My toolkit spans backend APIs, DevOps pipelines, and computer-vision projects on Raspberry Pi.

• fast_api_prac: Designing high-performance, secure APIs with FastAPI and SQLModel.

• Advanced FastAPI patterns
• Microservices architecture and service mesh
• API security best practices (APSec)

• mudflap_calculator: Python package to process and summarize daily fuel transaction CSVs, with robust validation and directory management.
• Custom Loyalty Server: Implemented Gilbarco Passport loyalty interface (v1.2) via Python TCP server.
• POS XML Automation: Watchdog-based pipelines to ingest and transform incoming XML files into PostgreSQL.
