🧠 Integrating AI into automation workflows and content generation

Problem: AI coding agents like Claude Code need access to secrets and APIs, but exposing credentials directly creates critical security risks.

Solution: Secrets management platform with a native MCP server, allowing AI agents to access credentials securely without ever exposing them in plaintext.

Architecture: Envelope encryption with Google Cloud KMS

AI Agent (Claude Code)
   ↓ MCP Server
SecureCode HQ
   ↓ KEK/DEK Envelope Encryption
Google Cloud KMS
   ↓ Decrypted on demand
Your APIs & Services

Tech Stack:

• Backend: Node.js, TypeScript, Firebase Functions
• Security: Google Cloud KMS, TOTP/2FA, JWT, envelope encryption (KEK/DEK)
• Distribution: npm SDK, Chrome Extension, MCP Server
• Frontend: Next.js, TailwindCSS

Key Features:

• Native MCP server for Claude Code integration
• Envelope encryption: secrets never stored in plaintext
• TOTP/2FA for agent approval flows
• Tag-based secret organization with visual hierarchy
• npm-published SDK for programmatic access

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

I build systems that:

• Reduce entropy — Clear interfaces over unnecessary complexity
• Scale cognitively — Architectures teams can understand
• Prioritize experience — For both developers and end users
