→ Real-time e-commerce data synchronization
→ AI-powered application optimization

I build systems that simplify technical complexity and improve developer experience.

🏗️ Building CTY — multi-tenant e-commerce platform with event-driven architecture
🔬 Evolving MAKO — specification for LLM content optimization
🧠 Integrating AI into automation workflows and content generation

Problem: Online store owners manually manage catalogs across multiple platforms (WooCommerce, PrestaShop) without technical expertise.

Solution: Centralized product management system with automatic bidirectional multi-CMS synchronization.

Architecture: Clean Architecture + DDD + CQRS + Event Sourcing

Product Catalog (Central Source)
   ↓ Domain Events
Event Bus (Firebase)
   ↓ Event Handlers
Sync Workers
   ↓ Bidirectional Webhooks
WooCommerce | PrestaShop | Shopify
   ↓ Real-time updates
Observability Layer (Grafana Cloud)

Tech Stack:

• Frontend: Next.js, React, TypeScript, Tailwind CSS
• Backend: Node.js, Firebase Functions, Firestore
• Observability: Grafana Cloud, distributed tracing
• Integrations: WooCommerce REST API, PrestaShop WebService, custom webhooks

Key Features:

• Zero-friction interface for non-technical users
• Bidirectional real-time synchronization
• Event system with replay capability
• Multi-tenant with per-tenant data isolation
• Complete observability: traces, logs, metrics
• Robust error handling and automatic retries

AI Integrations (in progress):

• Automatic product description generation
• AI-assisted SEO optimization
• Intelligent catalog categorization

Actively in development - sync architecture operational

Problem: Traditional HTML is inefficient for LLMs — high token consumption, semantic noise, unoptimized structure.

Solution: Open specification based on HTTP content negotiation that delivers structured content for AI agents.

Result: ~93% fewer tokens compared to standard HTML.

Client (LLM Agent)
   ↓ Accept: text/mako+markdown
Server
   ↓ YAML frontmatter + Clean Markdown
Response
   → 93% token reduction
   → Structured metadata
   → Actionable navigation

Impact: Reduces API costs in RAG applications and improves response accuracy by eliminating HTML noise.

Problem: Firestore lacks visual schema documentation, making team collaboration difficult.

Solution: Open-source visualizer that auto-discovers .schema.json files and renders interactive documentation.

Features:

• Static SPA, zero-backend, deployable on any CDN
• JSON Schema 2020-12 standard
• Automatic mapping of folder structure to Firestore collections
• Schema generation via LLM prompts
