As a freelance backend specialist contracted through BB Smart Services, a Netherlands-based consultancy led by Devon Marties, I was brought in to overhaul the backend architecture for their client, WinVote.io. The initial system was fragmented across three separate repositories, creating a chaotic and unmaintainable development environment. The architecture lacked type safety and was designed for a single DAO, making it impossible to scale into the "DAO-as-a-Service" platform the company envisioned

My Solution: I took ownership of the backend and executed a complete architectural overhaul.

Code Consolidation & Type Safety: My first step was to consolidate the three messy repositories into a single, cohesive monorepo. I then introduced TypeScript across the entire codebase, which immediately improved code quality, eliminated a class of runtime errors, and made the system far easier to maintain.

From Single to Multi-Tenant: I led the architectural shift from a single-DAO model to a true multi-tenant system. I designed and implemented a robust solution using Cloudflare Durable Objects to manage the state for each individual DAO, guaranteeing complete data isolation and security.

Scalable Serverless API: I rebuilt the core API using Hono, a high-performance framework ideal for Cloudflare's edge network. This made the system faster, more efficient, and ready for global scale.

Real-Time Functionality: I leveraged Cloudflare WebSockets to provide the real-time communication necessary for live voting and proposal updates, a critical feature for a successful DAO platform.

The Outcome: I successfully transformed a fragmented and unscalable project into a robust, production-ready backend. The new architecture is now maintainable, secure, and built to handle thousands of concurrent DAOs, directly enabling WinVote's core business model.
