About

A little background

I run RushDevs, an independent software studio building websites, web apps, and mobile apps for startups and small teams — and I build my own products under the same roof, three of them live and paid.

That follows 4+ years designing and shipping full-stack, distributed systems at Afresh, Speer, and Bell Canada, owning critical systems end-to-end from architecture through on-call operations.

Founder & Principal Engineer

Jul 2026 - Present

RushDevs

Independent software studio — web, mobile, and the systems behind them

Work with startups and small teams end-to-end: scoping the problem, designing the architecture, shipping the product, and running it in production afterwards.
Build and operate my own products under the same roof — MugUp, ManyMin, and EasyReports are live and paid, with Learn Quran on the web and Hayya on the App Store.
Bring the same stack I ran at enterprise scale to smaller teams: TypeScript, React, Next.js, Node.js, and PostgreSQL, on cloud infrastructure provisioned as code.

Projects

Products I’ve built and run

Shipped end-to-end — design, build, billing, and the infrastructure underneath.

Founder

MugUp

Live

Turns showing up for yourself into a game — AI-built quizzes and flashcards with spaced repetition, plus reading, writing, speaking, and habit streaks, all scored as six real-life stats on a daily Life Card. I run it as a product: content generation, subscriptions, billing, and infrastructure are all mine. Self-hosted rather than serverless to keep unit costs flat as usage grows.

ManyMin

Live

macOS screen-time tracker that samples the frontmost app once a second and splits browser time by website, shown live in a floating HUD and the menu bar. Daily goals and per-app limits, and going over can pulse the HUD or turn the whole screen grayscale. No account and no sync — everything stays in a local SQLite database. Sold as a $29 one-time purchase through Stripe, signed and notarized.

EasyReports

Live

AI report card generator for Ontario elementary teachers, with output aligned to Ministry of Education templates. Built and sold as a paid product — auth, billing, bulk field updates, colleague sharing, and a generation pipeline tuned to keep each teacher’s voice intact.

Learn Quran

Live

Section-by-section memorization guides covering Juz 29 and Juz 30 — verified Arabic and translation, thematic breakdowns, key vocabulary, and five practice modes per surah. Statically exported with no backend or login; progress lives in the browser. Companion iOS and Android apps in progress.

Hayya

Live

Mobile app that turns Muslim prayer times into insistent, call-style alarms — a full-screen "incoming call" UI with themed ringtones, streak tracking, and a written-reason flow for declining. Exact-alarm scheduling and full-screen lock-screen intents on Android, time-sensitive notifications on iOS.

HadithBot

Live

Discord bot that posts a daily hadith and the 99 names of Allah to any server that invites it. Each channel keeps its own place in the collection — book, chapter, and name — so servers that join later start from the beginning, and ten slash commands cover random or specific lookups. Runs 24/7 in Docker on an Oracle Cloud always-free VM.
