Everyone deserves the ability to express their dream.

Every day +1 Something new learned

Vision

I believe everyone deserves the ability to express their dream. Building is how I express mine, and how I help other people reach theirs.

What drives me

Curiosity keeps me moving. Every day I learn something new, and every new skill becomes one more way to help someone move forward.

  • UE5 Gameplay and engine tooling

I have been a developer, a tester, a consultant and a CTO, and my value sits where those roles meet. I build with a tester’s instinct for what can break, a consultant’s ear for what the client really needs, and a leader’s sense of what moves a team forward. The result is work that ships fast, holds up, and makes sense to the people who use it.

Agentic OS

The Agentic OS command center: a glowing teal orb for the Jarvis voice assistant with the prompt Tap, press J, or just talk; the next calendar event; the items waiting for approval; and a row of sections: Today, Mail, Tasks, Plans, Autopilot, Claude and More.
Fig. 02 — The command center, running on my own machine

My Agentic OS is a personal operating system where AI does real work with my context, like an AI personal assistant.

    The files are the system Everything the dashboard shows is plain Markdown and JSON that can be opened, read and edited.
  2. 02
    Propose, then approve Tasks, calendar events and code changes wait for my click.
  3. 03
    Bounded autonomy Every autonomous run has a trigger, a definition of done, a verification step and an output path.

How I work

I move fast without cutting corners: short iterations, close communication and AI as a force multiplier, with quality and customer satisfaction above everything else.

Speed, with care

Fast · Iterative · Close to the customer · Quality first

01

AI as a force multiplier

Agentic workflows, every day

AI as a force multiplier

I work alongside AI agents daily, handing them research, drafts and code, then reviewing every result before it ships. More output, the same standard, and my judgement stays in the loop.

02

Fast, iterative delivery

Ship small, learn quickly

Fast, iterative delivery

Small releases and short feedback loops, so the direction can change while change is still cheap. In a market that moves this fast, the speed of learning is the edge.

03

Close communication

No surprises

Close communication

Regular check-ins, clear updates and questions asked early. Staying close to the people I build for means what gets built is what is actually needed.

04

Quality built in

A tester’s eye

Quality built in

Testing taught me to look for what breaks before users do. Verification and a clean handover are part of the work, never an afterthought.

05

Customer first

Satisfaction above all

Customer first

Success is measured by the person using what I build. I would rather ask one more question than deliver the wrong thing well.

06

Skills that transfer

Many roles, one toolkit

Skills that transfer

Development, testing, consulting and leadership each sharpened something different. Together they let me see a problem from the user’s side, the tester’s and the business’s.

Experience

I learn fastest where it matters: testing products before users meet them, automating data work in banking, and building tools that make teams faster.

Why I build

I want to help people reach their goals, reach more people, and have a larger impact on their community, or on the world as a whole.

01

Thirsty for knowledge

Every day I’m doing or learning something new, and looking for a way to put it to work for someone.

02

Built for people

Technology is a way to give people more reach. I build tools that help someone express an idea, grow what they’re making, or get their time back.

03

Impact that grows

Start by helping one person, then a team, then a community. Small tools, used well, add up to a larger impact.
