Overview

Kutsbee is a two-sided SaaS marketplace that connects people looking for salons, spas, and barbers with the businesses that offer those services. Businesses register and set their location, list their specialists, available hours, and pricing; end users search by location, specialist availability, and hours, then book — with everything tracked on the platform.

My Role & Contributions

I was responsible for the backend and the web side, and also provided the APIs the mobile apps consumed. The standout pieces of work were mine:

  • Specialist availability engine — wrote a complex API that computes a specialist's availability, working hours, and bookable slots. It was the most complex part of the platform and took 3–4 days to get right, alongside the order-creation flow.
  • Escrow payments (Stripe) — implemented escrow-based payments: businesses subscribe to the platform and users pay for services, with Kutsbee taking a per-order cut from both sides and paying the remainder out to the salon.
  • Location search — built Google Maps-based locations with MongoDB geospatial indexes so users can search efficiently by proximity.
  • Auth & access — integrated Google OAuth and implemented RBAC on the admin side.
  • Architecture — designed a fully modular backend structure.
  • Web — built the Next.js web apps using Tailwind CSS.

Key Features

  • Two-sided marketplace — businesses and clients on one platform.
  • Business profiles — location, specialists, available hours, and pricing.
  • Location & availability search — find specialists by proximity and open slots.
  • Booking & order creation — reserve services through the platform.
  • Escrow payments — Stripe payments with a platform commission split.
  • Subscriptions — businesses subscribe to be listed.
  • Admin with RBAC and Google OAuth sign-in.

Tech Stack & Architecture

  • Backend: Node.js with MongoDB, built on a modular structure.
  • Web: Next.js with Tailwind CSS.
  • Mobile: React Native apps that consume the APIs I built.
  • Payments: Stripe — escrow, per-order commission split, and subscriptions.
  • Location: Google Maps with MongoDB geospatial indexes.
  • Auth: Google OAuth plus role-based access control.

Challenges & Solutions

  • The availability engine — the hardest problem was computing real-time specialist availability across working hours, slot durations, and existing bookings. I built a dedicated API to resolve all of that into clean, bookable slots; it was the most complex piece of the system.
  • Escrow with a commission split — money flowed from both businesses and users, so the payment logic had to take Kutsbee's per-order cut and pay the remainder to the salon, all handled through Stripe.
  • Geospatial search at scale — indexing locations in MongoDB so proximity search stays fast as listings grow.
