git log --author="Rafeek" --since="6 months ago" returns, roughly: a graph pass inside PyTorch's on-device runtime, a church management platform in Arabic, and a great deal of reading other people's code very carefully before touching it.
CS at Minerva University, San Francisco, class of 2029. Backend-leaning. Currently looking for a Summer 2027 software engineering internship.

⛪ Ekklesia — church management, Arabic-first
Next.js 15 · TypeScript · Supabase · PostgreSQL · Twilio · Resend
Most churches I know run on three WhatsApp groups and a spreadsheet someone's cousin made in 2019. Visitors show up once and are never followed up with. Ekklesia replaces all of it: QR-powered visitor registration with an automatic follow-up pipeline, attendance tracking with at-risk alerts, small groups and prayer requests, volunteer scheduling, a song library with presenter mode, and a Bible reader — multi-tenant, Arabic-first and fully RTL, with a six-level role model from super_admin down to member.
Priced at cost. No margin, no tiers. It's live →
What I own:
- First engineer on the project after the founder
- End-to-end testing across the platform — found and reported 10+ bugs before they reached production users
- The full production API configuration on Vercel
- Database query optimization across the multi-tenant Postgres schema (~94 tables)
Built with the founder. The source is private — it holds real congregation data — but I'm happy to walk through the architecture, or grant repo access for a code review. Just ask.

Every engineering decision your team ever made is sitting in a Slack thread nobody can find. This watches Slack events and huddle transcripts, spots the decisions, and indexes them as embeddings so you can ask in plain English why something is the way it is. Ingestion runs on a worker queue behind the API, so a firehose of messages never blocks a read.

| Project | What I contributed |
|---|---|
| pytorch/executorch | ReplaceSliceCopyWithSlicePass — an EXIR graph pass that spots contiguous, unit-step slice_copy nodes able to alias the base buffer instead of copying it. On a phone or a wearable, that's a whole tensor copy removed from every single inference |
| apache/airflow | An optional static_url on BaseOperatorLink. If a link is a constant, it no longer needs an XCom write and a metadata-DB read on every task run. Default behaviour unchanged, so nobody's DAG breaks |
| pandas-dev/pandas | Linked 11 API-reference pages back to the user guides that explain them, closing #62357. Small diff, long review — worth every round of it |
| wso2/identity-apps | A 400 on the self-registration redirect, traced to a claims JSON parameter that was HTML-escaped but never URL-encoded. Nine characters of the fix, most of the work in reproducing it |
Longer write-ups — how I picked the issue, what the codebase actually looked like from the inside, and how the review went:
- Re-inplacing
slice_copyin ExecuTorch — finding an aliasing case an existing pass already handled forview_copy - Skipping XCom for constant operator links in Airflow — removing an abstract method without breaking every subclass that implements it
- Chasing a 400 through the WSO2 login flow — reproducing the failure before writing a line of the fix
