Available for new projects
I turn half-formed ideas into software people actually use.
Currently, Ibuild native iOS & Android appsI also build fast, findable websites, ship AI agents on Claude and Gemini, and 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.
Or just message me on WhatsApp. I answer my own messages.

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.
