Available for new projects

I turn half-formed ideas into software people actually use.

Currently, Ibuild native iOS & Android appsI build native iOS and Android apps, I build fast, findable websites, I ship AI agents on Claude and Gemini, and I teach software architecture and AI engineering.

I'm Gal — a fractional CTO and hands-on engineer. Many years of cloud architecture, secure backends and native mobile at Microsoft, Intel and Cellebrite, plus thirty-odd apps I've shipped on my own.

Why me

Hiring a senior engineer is mostly about avoiding expensive detours.

01
You get a decision, not a discovery phase
I have built this shape of system before. That means an architecture on day two and a working slice in week one, instead of a month of workshops.
02
The code is written against your P&L
Burn rate, hosting bill, and what a future acquirer will read in due diligence are design inputs. I will talk you out of the expensive version when the cheap one wins.
03
Enterprise habits, startup pace
Microsoft and Intel taught me threat models, review discipline and reproducible builds. Shipping thirty apps solo taught me when to skip the rest.
