CTO at Neuroject. Full-stack and embedded engineer, trained in nanoelectronics engineering.
I architect AI-driven platforms and scalable digital products.
Building since 2007: robots, IoT and firmware, then web, mobile and AI platforms.

Fig. 1–3. An illustration, not a measurement and not research results: a multi-quantum-well p–i–n diode loosely modelled on InGaN/GaN, grown so that position is time. Each well’s width is its role’s duration and its depth grows with it; levels come from the finite square well, the gap follows Varshni, current follows the diode law, and the rates are chosen to be visible rather than fitted. The facts in the notes are real.
§1 Abstract
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.
§2 Layer stack, top layer first
Every role, with the well it was grown as: the wider and deeper the well, the longer the role.
Chief Full Stack Engineer → CTO
June 2024 – Present
Built NeuroBuild, then CTO of the alignment layer for construction enterprises.
1.37 nm wide (0.6 nm a year) · 0.73 eV deep · 1 bound electron state · emits 453 nm, blue
Chief Full Stack Engineer (contract)
May 2026 – Present
Contract role alongside Neuroject.
A contract alongside: grown as a δ-doped sheet inside the current well, not a layer of its own.
Lead Frontend Developer
February 2021 – June 2024
Active-Class LMS and proctoring, Attendum firmware and apps on both stores.
1.90 nm wide (0.6 nm a year) · 0.81 eV deep · 2 bound electron states · emits 493 nm, blue
Senior Frontend Developer
August 2020 – February 2021
A React marketplace that took local grocers online.
0.20 nm wide (0.6 nm a year) · 0.53 eV deep · 1 bound electron state · emits 368 nm, ultraviolet
Software → Senior Software Engineer
October 2012 – August 2020
IoT platforms, live GPS tracking and connected devices.
4.60 nm wide (0.6 nm a year) · 1.05 eV deep · 4 bound electron states · emits 630 nm, red
Web Developer
August 2007 – October 2012
Websites and web apps for clients in PHP, JavaScript and jQuery.
3.05 nm wide (0.6 nm a year) · 0.92 eV deep · 3 bound electron states · emits 557 nm, green
§3 Localized states
What shipped. In the diagram each one is a small dip in the well of the year it shipped, where carriers settle.
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.
AI-assisted R&D tax credit claims for the UK, Ireland, Australia, and South Africa. I work across the FastAPI and pgvector API, the SvelteKit app, and the TypeScript client SDK, and added its security gates: secret scanning, Semgrep, and Trivy on every pull request.
Attendance monitoring live at universities in the UK and US. I wrote the firmware for the ESP32 card readers (NFC, RFID, BLE, over-the-air updates) and the nRF52840 Bluetooth beacons, and built the iOS and Android app, the staff dashboard, and a Canvas LTI app. At a single university, it has more than 200 devices online, covers over 100 classrooms and 10,000 classes, and has received over 3 million records in the past two years.
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.
An LMS with live exam proctoring and Azure Face identity checks. I built the user dashboard, an Office add-in that brings live polls and word clouds into PowerPoint and Word, and the product website.
A React Native app on both stores that helps students starting university get to know their course, campus, city, and career options.
Expo · React Native · TypeScript
Online tutoring for every child: diagnostic tests, courses, quizzes, and 1-to-1 lessons over live video. I built the dashboard and the website.
Next.js · MUI · VideoSDK · Uppy
An electronic pressure and flow controller: embedded hardware and firmware that hold pressure and flow at their setpoints. In production.
Hardware · Firmware · Process control
A compact PLC controller built on STM microcontrollers: the board and firmware for automation on a small footprint. In production.
STM · Firmware · PLC
An opt-in flag I added to react-query-kit (31k weekly downloads) so a forgotten query argument fails at compile time instead of at runtime.
TypeScript · React Query
Removed a deprecated uuid version from gatsby-cli and gatsby-plugin-sharp that could fall back to Math.random() and was flagged on every Gatsby install.
Node.js · Security
Device telemetry on plain shared PHP hosting: ingest, rollups, alarms with hysteresis, OTA firmware, and reports. No Composer, npm, or build step.
PHP 8 · Vanilla JS · OpenAPI
A native macOS app that finds duplicate and look-alike photos by how they look. Fully offline, and nothing is ever deleted.
Swift · SwiftUI · Vision
Reads matrix keypads as a FreeRTOS task, with built-in debouncing and configurable layouts and pin maps. Portable across microcontrollers.
C · FreeRTOS
Fixed persisted data being wiped when the app was opened in a second tab, in a store used 82k times a week.
TypeScript
The product website for Learning Kit, built for 0&1.
Next.js · AWS Amplify
The product website for Exam Kit, an online exam monitoring system by 0&1.
Nuxt · Tailwind CSS
§4 n⁺ contact · in production
Devices still running in the field. In the diagram they are the states in the n⁺ contact, where electrons leave as current.

§5 Upstream
Bugs fixed at the source, in packages downloaded more than 300k times a week.
Security2022★ 56k · 163k a week
Impact. That version can fall back to Math.random(), which is unsafe for IDs. npm flagged it on every install.
Fix. Removed the deprecated uuid@3.4.0 from gatsby-cli and gatsby-plugin-sharp.
Data loss2022★ 383 · 82k a week
Impact. Opening the app in a second tab wiped saved data.
Fix. Synced storage events only for the store’s own key.
Type safety2026★ 486 · 31k a week
Impact. A forgotten argument compiled fine and only failed at runtime.
Fix. Opt-in strictVariables: typed query variables become required at the call site.
Type safety2025★ 51k · 22k a week
Impact. Calls that Autodesk documents failed to type-check.
Fix. Typed the optional RegExp filters on the Forge Viewer’s getPropertyHashes.
Bug2021★ 119 · 5.4k a week
Impact. Refs passed to localized links were silently dropped.
Fix. Added forwardRef support to the localized Link.
