TimeTracker: the system I built instead of buying one
Jul 29, 2025 · 5 minI build my own business systems instead of buying them. TimeTracker was the first: built with Claude Code, Cursor and Supabase, it cut my monthly admin from 4-5 hours to about 30 minutes.
TimeTracker: the system I built instead of buying one
When I decided to go freelance as an AI consultant and project manager, I knew what I was getting into. After years in the industry I had watched consultant after consultant fight their own tools, systems that were either too simple or far too complex for the job. I made a different call: I would build all my business systems myself.
TimeTracker came first
Time tracking and invoicing are the backbone of a consulting business. I had tried it all: Jira, Harvest, Toggl, assorted Excel setups. None of them fit how I wanted to run my business.
Jira had become a beast. Every time I logged hours, it felt like navigating a maze of fields I didn't need.
So I built TimeTracker. My own system, designed for how I actually work as an AI consultant.
The stack
I'm an AI consultant and a vibe coder, so I picked tools that give me speed and room to move:
- Claude Code and Cursor as my development copilots
- Supabase as the backend, a deliberate choice for its real-time capabilities
- GitHub and Vercel for deployment: push to main, and the system is live
More than time tracking
TimeTracker quickly grew past logging hours:
- Project structure: the system knows the difference between AI development projects, strategic advisory and workshops
- Automated admin: it generates invoices, project status reports and profitability calculations
- Client insight: it tracks changes and tells me when it's time for a conversation about hours and budget
From reactive to proactive
I used to spend 4-5 hours a month on administration. Now it's maybe 30 minutes. The bigger win is the insight. The system gives me real-time data on my business.
An ecosystem of my own tools
TimeTracker was just the beginning. I'm building a whole set of tools now:
- A CRM designed specifically for selling AI projects
- A knowledge management system for organizing research
- Automated reporting tools for project stakeholders
Why this makes sense for an AI consultant
Building your own systems sounds backwards for a consultant. But my systems are my competitive advantage. They show potential clients that I don't just talk about digital transformation, I run my business on it.
The road ahead
As my consulting business grows, the systems grow with it. Every friction I hit becomes a new feature. I think this is where consulting is heading: using modern AI tools to build exactly what your business needs.
Ideas are cheap.
Systems ship.
Tell me what you are building. I will tell you straight what is worth doing.
