Under the Hood · Signature Details

Three details that don't fit in a bullet point

The résumé version says "race-safe," "fail-closed," "custom color engine." Here's what those actually do — three small machines you can poke. No libraries, no canvas, just SVG and vanilla JS.

Handly · Go + Postgres

One job, three helpers, one winner

Atomic compare-and-swap matching Three helper tokens race one pending job. A single conditional UPDATE fires; exactly one row locks to assigned, the losers bounce off. job · status=pending A B C UPDATE jobs SET helper=? WHERE id=? AND status='pending'

rowsAffected is 1 — always. The DB, not the app, is the referee.

Booking Platform · Node webhooks

Money that can't slip through

Fail-closed webhook money path A payment webhook advances through three gates: HMAC-SHA512 signature, amount reconcile, and idempotency. A valid packet clears all three; a tampered amount fails closed at the reconcile gate. HMAC SHA512 amount reconcile idempo- tency ledger $

No gate passes cleanly? The row never touches the ledger. Silence is a rejection.

Atlantis Colors · HSL / OKLCH engine

Viridian

AA 4.9:1 ✓ white on base

The real engine walks 2,000 palettes in HSL, snaps to OKLCH for perceptual sorting, and names each one. Same math, fewer swatches.

Why work with me

Hiring a freelancer shouldn't feel like a risk.

  • End-to-end ownershipOne person answers for the data model, API, payments, app and CI — me. No hand-offs, no finger-pointing.
  • Fast communicationSame-day replies in English or Arabic, and honest status updates — including the bad news, early.
  • Production-ready codeTested, hardened and monitored — the kind of code this very page counts live, not demo-ware.
  • Product thinkingI'll push back on features that don't serve your users — your budget goes where it moves the needle.
  • Scalable architectureClean layers, real migrations, race-safe writes — built so growth is an upgrade, not a rewrite.
  • Long-term supportI stay after launch — maintenance, monitoring and iteration. Your product keeps improving.
