ParkBlue

Overview

ParkBlue connects drivers with people who own a private parking spot. Drivers find a guaranteed space in seconds; owners turn an idle driveway into income. The product spans a marketing site, a booking flow and a native mobile app for both sides of the marketplace.

The challenge

Trust and timing in a two-sided marketplace.

Parking is a high-frequency, low-margin transaction with zero tolerance for friction — a driver who can't find or book a spot in 30 seconds defaults to the nearest paid lot. At the same time, owners need rock-solid scheduling, payouts and accountability before they'll list. The brief was a product that feels instant on the driver side and feels safe on the host side, all on one shared backend.

My approach

Shared API, dedicated experiences.

I worked across the full stack — a typed Node.js API on AWS with PostgreSQL, the marketing site on Next.js, and a React Native app shared between drivers and hosts but with two finely-tuned UX flows. Real-time availability uses a single source of truth so a spot can never be double-booked. Payments, payouts and notifications are wired through Stripe and a queue worker; everything ships with strict types end-to-end.

Results

A live marketplace shipping every week.

ParkBlue is live in Prague with active hosts, active drivers and a steady weekly release cadence. The mobile apps are on both App Store and Google Play. The product keeps a < 1s time-to-spot on the booking flow and a healthy host retention thanks to the payout and scheduling guarantees built into the core.
