Project Overview
Sprachly is a modern real-time communication platform built using a vibe-coding workflow. Rather than manual line-by-line coding, I acted as Product Engineer — focusing on system architecture, security logic, and orchestration of professional-grade external services. I directed AI agents for rapid prototyping while personally solving complex integration challenges, governing the technical stack, and ensuring production-level security through Supabase Row-Level Security policies.
