Hermosa Booking Engine
An advanced booking & operations platform built for a women's salon - designed not around a calendar, but around "how a salon actually operates" under real daily pressure.

A backend for flash sales thousands of buyers, limited stock,one second. Built twice: synchronously, then queue-based.
I replaced 10+ fragmented dashboards and command-line interfaces with a single <b>Unified Abstraction Layer</b>. This project solves the "fragmentation fatigue" that leads to high support ticket volume and operational inefficiency.
I built a backend that treats “place order” as a fast, safe entry point, then moves the heavy work into workers with controlled concurrency. Order state is streamed live using SSE instead of polling — reducing API chatter and keeping the DB off the hot path.
A minimal decentralized blockchain prototype built from scratch in Node.js. Nodes communicate over WebSockets, synchronize state using a custom protocol, and converge using a Longest Valid Chain rule — demonstrating the mechanics of trust without a central server.
A lightweight React form engine that turns scattered per-page form logic into one consistent abstraction. It reduces boilerplate, standardizes validation + error handling, and stays UI-agnostic so it can plug into any design system.
A clean, investor-friendly company website plus a structured digital catalog that makes technical product specs easy to scan — without sacrificing speed or clarity.
