FastAPI and PostgreSQL backend systems for finance workflows, data ingestion, bookings, ticketing, and operations.
Overview
At ConsultFox, I worked across two product areas: a personal finance platform and an event management platform. The work focused on backend service design with FastAPI and PostgreSQL, reliable data modeling, CSV ingestion, booking and ticket workflows, payment-support features, and production-ready deployment practices.
Personal Finance Platform
- Developed backend data services in FastAPI and PostgreSQL for authentication, accounts, transactions, and categories
- Designed structured data models for multi-currency accounts, recurring transactions, and statement records
- Built CSV ingestion pipelines with validation, normalization, and duplicate detection to improve import reliability
Event Booking, Ticketing & Payments
- Led development of an event management platform with booking flows, ticket generation, and payment-support features
- Implemented core service logic across API, database, PDF ticket generation, and SEPA QR payment support
- Kept the architecture maintainable through clean separation of concerns and pragmatic service boundaries
Production Readiness & Engineering Standards
- Improved runtime readiness with containerized deployment, environment-based configuration, and support for Docker Compose and Gunicorn setups
- Applied structured logging, input validation, error handling, and modular utilities across the codebase
- Focused on reliability and maintainability so the platform could support real operational usage and future growth
