The tools behind your solution

Built around
what you need.

I combine AI, automation platforms, and databases to build solutions around your processes and the apps you already use.

01 / 03Plan & build

Building with AI

From your idea
to a working solution.

I work with Codex, Claude, and Antigravity throughout development to build custom apps, automations, and AI assistants. I guide the process, connect the pieces, and test the result against what you need.

  1. Plan
  2. Build
  3. Connect
  4. Test

When needed, I also integrate AI into the finished solution—to analyze information, generate content, or assist users.

Orbiting development assistants: Codex for AI-assisted coding and implementation; Antigravity for agent-assisted development and integrations; Claude for reasoning, drafting, and code assistance.

Explore the orbiting tools.

02 / 03Connect & act

Automation & integrations

Connect your apps.
Keep work moving.

I connect your apps with n8n, Make, or Zapier, so information moves and tasks happen automatically.

How I build it

Each workflow follows your process, with approval steps and error handling where needed.

n8n powers the examples below. Make and Zapier are other options we can choose around your tools and the task.

Orbiting automation platforms: n8n, Make, and Zapier. Options to consider according to your existing tools and the task.

03 / 03Organize & access

Supabase

The foundation
behind your app.

I use Supabase, built on PostgreSQL, to organize your app’s information, manage user accounts, and work with files. I connect these pieces to your app, automations, and AI features, with access rules for each user.

  • Data & files
  • User accounts
  • Access rules

Supabase is the main orbiting platform. The four smaller icons represent PostgreSQL for records and workflow history; Deno for custom logic and webhooks through Edge Functions; PostgREST for the REST API; and GraphQL for querying related data. These technologies are used according to the application.
