Backend Development

Production REST APIs in Python (FastAPI) and TypeScript (NestJS) - multi-tenant, role-based, and hardened where it counts: rate limiting, optimistic concurrency, event-driven pipelines. Structured so the developer after me can actually pick it up.

Agency Booking Platform
Featured Project

Agency Booking Platform

Live Demo

Multi-tenant SaaS for travel agencies & hotels

Centralized reservation and operations management for travel agencies and hotels. Each agency manages its own data — flights, hotels, car rentals, invoices, commissions — while a central team oversees the full operation and provides support. Agencies can push bookings automatically from their own websites via API.

25 years in tourism operations shaped this system around the domain — commission calculations, voucher management, agency credits, and other tourism-specific details a generic booking tool would miss.

About

Backend systems built to last.

I come from operations, not from a code background. 25 years running live operations in tourism, where downtime wasn't a red dashboard, it was real people stranded at a gate. I know what reliability actually costs, and I build with that reflex.

Today I build production-ready systems in TypeScript (NestJS, Next.js) and Python (FastAPI), with an emphasis on stability and low operational overhead: multi-tenant APIs, event-driven automation, PostgreSQL, Docker, and AWS.

No agencies, no middlemen. Direct communication, direct delivery.
