Selected projects
Learning and commerce
Baroot CNC
An English and Arabic platform for CNC and manufacturing, with academies, courses, live sessions, certificates, a store and a page builder. Its AI assistant detects Arabic dialects, the server sets every price, and each payment is re-verified with the gateway before it settles.

Multi-vertical commerce
RAWHNA
An Algeria-first platform for marketplace, vehicles, services, real estate and luxury, built around dinars, wilayas and cash on delivery, in four languages with Arabic right-to-left. Search fuses full-text and vector results, row locks prevent overselling, and 43 live probes check that tenants stay isolated.

Healthcare platform
Med-Engine
A multi-tenant platform for patients, nurses, doctors and hospital admins: provider discovery, booking with payments, an encrypted document vault, referrals, communities, and chat with voice calls. Background work runs on a Postgres job queue and NATS JetStream, with no Kafka.

Native macOS app
Notch Island
Turns the MacBook notch into a Dynamic Island style surface for AI agent events with Allow and Deny, notifications, calls, media and usage limits. Written entirely in Rust on AppKit, with its own spring animator on a fixed 240 Hz sub-step and a self-test that asserts state, geometry and pixels.

Market prediction research
Predictify
Ingests live crypto, equity, gold and FX data, trains a model on one-minute bars and scores every prediction in an immutable ledger. Signals stay paused because the model failed its own cost-adjusted, purged walk-forward gate, and the site says so rather than showing a number it hasn't earned.

E-commerce back office
Ecommercia
A multi-tenant workspace for shop owners and staff, covering orders, inventory, deliveries, accounting and support in three languages. Moving the orders query to a single round trip cut p95 from 694 ms to 64 ms, and a k6 run of 43,478 requests saw no failures and no orders leak between tenants.
