Goal: Design and build a centralized, subscription-based orchestrator platform that allows merchants to register, choose subscription plans, and instantly deploy their own custom e-commerce store instances.

Solution: Built a multi-tenant platform using Next.js and a shared-process model. Implemented tenant isolation by dynamically provisioning unique PostgreSQL databases, establishing private MinIO/S3 storage buckets, and updating routing tables in real time via Caddy's admin API. Integrated payment webhook verification to handle automated deployment and immediate suspension of store routes based on billing status.

Impact: Replaced slow manual setup times with a secure, instant provisioning engine that deploys complete database and storage structures in seconds while ensuring data isolation between stores.

Goal: Build a lightweight, responsive storefront catalog that enables customers to browse items, assemble a local cart, and send structured orders directly to the merchant via messaging channels to bypass traditional checkout friction.

Solution: Developed a mobile-first catalog integrated with tenant-isolated database access. Designed a robust local cart utilizing reactive state signals (@preact/signals-react) to maintain persistence across sessions. Built a mechanism that parses the cart selections into a cleanly formatted, readable text order transmitted directly to the merchant's device via the WhatsApp API.

Impact: Provided small-to-medium retailers with a frictionless, commission-free checkout method that simplifies user transactions and lowers cart abandonment rates.
