Who I am
Doing is the work. Talking about how is a distraction.
- Hands-on architect and CTO. Today I build software products that remove the boring, low-value-added work professional slide decks require.
- I work for the people in PowerPoint. Consultants and middle-managers across industries live in slides — they need evolving tools to keep up with rising expectations and fast-paced competition.
- Delegation and empowerment over heroics. I aim to bring out the best in anyone building a solution, then get out of the way.
- Writing is my default channel. Structure and clarity beat charisma every time, especially when the stakes are high.
- Off-hours: coaching, games, fiction. Tech-leadership coaching, game design docs and prototypes for AerelonTech, and science-fiction writing.
- Build small and well. I’d rather ship a small thing well than describe a big thing forever.
Personal values
Five Es. They show up in every decision.
-
Embrace
Family and friends first. Strangers and acquaintances always treated with kindness and respect. Lives and health over any other priority.
-
Entertain
Make others feel, think, laugh, or be amazed — to disconnect from their problems for a short while.
-
Engage
Teach. Inspire thinking about new ideas — in tech, in principle, or in art.
-
Empower
Enable others to follow and build upon, so they can achieve more in peace than was possible before.
-
Enjoy
Life is too short not to.
Experience
Fifteen years on the keyboard. Five at the helm.
From Silverlight line-of-business tools to greenfield banking, from Tech Lead at IncepTech to Principal Engineer at McKinsey, to founding roles today. Same posture throughout: ship the thing, raise the team.

Said about me
Words from people I’ve worked with.
The clearest signal of how I work is what colleagues say after shipping with me. Names altered or hidden where NDAs apply.
-
“I would point out that you can connect engineering and business worlds. You have huge experience and great people skills. Best experience that you entered our project and calmly got it back on track. At the time I could not imagine myself doing that.”
Roland Sz. — senior data engineer -
“Liked working with you. You took the lead, actively pushed and made it happen. Always supported your team, we could always count on you and your wide experience.”
Gergo V. — senior software engineer -
“You always had sharper insights than most. You could always go one step deeper for pros and cons that others missed. I liked that you gave us space to earn experience.”
Akos Sz. — senior engineer -
“Always kind, empathic, calm, very caring and professional. This combo is rare, especially in engineers.”
Richard T. — coach and people leader -
“His technical expertise is top-notch, and he quickly became a reliable pillar of the team. Over time, he grew into a conscientious and supportive leader. Someone you can always count on — both professionally and in people management. If anything, his high standards sometimes lead him to take on more than necessary, but that also reflects his strong sense of ownership and commitment.”
Andras M. — technical leader, senior software engineer -
“Direct, operative leader who earns respect with his technical and process knowledge. Quick, decisive and experimental while being thorough enough — these are great traits.”
Gabor B. — mobile dev chapter lead
