10⁰1 mark = 1 person
CTO at Neuroject, building the alignment layer for construction enterprises. Building since 2007: robots, IoT and firmware, then web, mobile and AI platforms.
Every stop below is a real figure from my career, drawn as exactly that many marks. Zoom out and each order of magnitude turns out to be made of the one before.

10⁰1 mark = 1 device
Five devices in production, from GSM weather stations to a compact PLC. On the field, each mark carries its tag.
Several sensors per station, with logs sent home over GSM.
50+ stations · 15+ years online · 0.5B+ records
Embedded hardware and firmware that hold pressure and flow at their setpoints.
In production
Built on STM microcontrollers, for automation on a small footprint.
In production
NFC, RFID, BLE and over-the-air updates. Wireless, with a battery that lasts about 16 months.
200+ devices online · 3M+ records in 2 years · 10K+ classes covered
Bluetooth proximity check-in, updated over the air with DFU.
In production
For both Attendum parts, the reader and the beacon, I wrote the firmware.
10¹1 mark = 1 year · 1 stripe = 1 month
From freelance websites in 2007 to CTO at Neuroject. Each mark is a year from August 2007. Its twelve stripes are its months, coloured by the role I held, with a lower band when a second role ran alongside.

Software → Senior Software Engineer
IoT platforms, live GPS tracking and connected devices.
Senior Frontend Developer

Contract role alongside Neuroject.
At Neuroject: Chief Full Stack Engineer from June 2024, CTO since September 2026.
10¹1 mark = 1 station
GSM weather stations that take several sensors each and send their logs home. The fleet has been online for over 15 years: more than 50 active stations and over half a billion records.
50+ stations · 15+ years online · 0.5B+ records
Their records come back at the end of the zoom, at 10⁸.
drawn: 50 (the figure is 50+)
10²1 mark = 1 classroomat one university
Attendance monitoring, live at universities in the UK and US. The Attendum figures here all come from one of them, where it covers more than 100 classrooms.
I wrote the firmware for the ESP32 card readers and the nRF52840 Bluetooth beacons, and built the iOS and Android app, the staff dashboard and a Canvas LTI app.
drawn: 100 (the figure is 100+)
10²1 mark = 1 deviceat the same university
More than 200 devices online at that same university. The two Attendum devices:
NFC, RFID, BLE and over-the-air updates. Wireless, with a battery that lasts about 16 months.
Bluetooth proximity check-in, updated over the air with DFU.
drawn: 200 (the figure is 200+)
10³1 mark = 1 commit
The alignment layer for construction enterprises: one multi-tenant platform for BIM models, WBS, quantity take-off, bills of quantities, tenders, and 4D progress reports, now with AI for natural-language questions and early risk warnings. I lead it as CTO.
Led the architecture and build of NeuroBuild on Next.js, React 19, and Laravel, hosted on AWS Amplify and Laravel Vapor, with 4,700+ commits across five codebases.
At Neuroject: Chief Full Stack Engineer from June 2024, CTO since September 2026.
drawn: 4,700 (the figure is 4,700+)
10⁴1 mark = 1 classat one university
Back at the same university, two powers up from its classrooms: Attendum has covered more than 10,000 classes there.
The marks are now a few pixels wide. Watch the gutters: every gap marks where a block of ten, a hundred or a thousand ends.
drawn: 10,000 (the figure is 10K+)
10⁴1 mark = 1 commit
Commits since 2021. The bright ones are NeuroBuild’s 4,700+ from 10³: the previous stop, sitting inside this one.
Written in
drawn: 11,800 (the figure is 11.8k+)
10⁵1 mark = 1 download a weekcombined, not per package
Fixes I sent upstream, to packages that together are downloaded more than 300k times a week. The figure is the combined total, so the field splits it by package.
2022 · Security · 163k a week · ★ 56k
Removed the deprecated uuid@3.4.0 from gatsby-cli and gatsby-plugin-sharp.
That version can fall back to Math.random(), which is unsafe for IDs. npm flagged it on every install.
2022 · Data loss · 82k a week · ★ 383
Synced storage events only for the store’s own key.
Opening the app in a second tab wiped saved data.
2026 · Type safety · 31k a week · ★ 486
Opt-in strictVariables: typed query variables become required at the call site.
A forgotten argument compiled fine and only failed at runtime.
2025 · Type safety · 22k a week · ★ 51k
Typed the optional RegExp filters on the Forge Viewer’s getPropertyHashes.
Calls that Autodesk documents failed to type-check.
2021 · Bug · 5.4k a week · ★ 119
Added forwardRef support to the localized Link.
Refs passed to localized links were silently dropped.
drawn: 303,400, the sum of the 5 weekly figures
10⁶1 mark = 1 recordfrom one university
More than 3 million Attendum records received in the past two years, from that one university.
A mark is now smaller than a pixel, so each square on screen is a block of marks and the readout says how many. The count stays exact; only the drawing is aggregated.
drawn: 3,000,000 (the figure is 3M+)
10⁷ No figure here lands on 10⁷, so the camera passes it rather than invent one. The next is 50 times larger.
10⁸1 mark = 1 record50+ stations, 15+ years
Over half a billion records from the Logger fleet, online for over 15 years: GSM weather stations with several sensors each, more than 50 of them active.
That is 8.7 powers of ten from the single mark at the top. All 500,000,000 are counted; on screen they are drawn in blocks.
drawn: 500,000,000 (the figure is 0.5B+)
From 1 to 500,000,000: 8.7 powers of ten.

Every figure on one log scale, smallest first. The bar’s length is the figure’s power of ten.

The 19 marks, at full resolution
I started building websites as a freelancer in 2007, studied electrical engineering with a focus on control systems, and spent my university years building robots, including a 1st place at RoboCup IranOpen 2010.
Since then I’ve built for an electronics and IoT company, a grocery marketplace, an edtech company and a construction-tech company. Today I’m CTO at Neuroject, leading the platform that connects BIM, schedules, budgets and risks for construction enterprises, and bringing AI into it.
Along the way I’ve shipped apps to the App Store and Google Play, hardware that’s still logging data after 15 years, and fixes to open source projects like Gatsby and DefinitelyTyped.
