Computer Science graduate & retail store technology specialist with 5+ years supporting POS/register systems, Cisco networks & connectivity across an 867-store environment. On personal time I ship 0→1 products, internal AI tooling & security tools.
Store technology by day. Builder & security learner by night.
I'm a Computer Science graduate (CSI / CUNY) and a retail store technology specialist with 5+ years at Rainbow Apparel — building, deploying, and personalizing POS systems, Cisco store networks, Inseego connectivity, and peripherals across an 867-store environment, and training 10+ new IT technicians.
Outside the day job I ship 0→1 products, internal AI tooling, and security-focused tools like Asset Vault (1,000+ devices) and Packet Analyzer. Cybersecurity is a separate, self-driven track.
867 stores, one network
The footprint I keep online every day — registers, Cisco networks, connectivity and peripherals across a nationwide retail fleet. Hover a node to inspect a store.
What I do
Store Tech & POS
Registers, Cisco store networks, Inseego connectivity, phones, scanners, receipt printers & store servers — built, personalized, and supported across 867 stores.
Products, AI & Security
Full-stack apps, local-first AI tools & security projects — product sense, backend/frontend range, automation, and a self-driven cybersecurity track.
Ring me up
I deploy point-of-sale for a living — so here's one. Add a few services, hit checkout, and the register prints your quote.
Why work with me
Ships to production
My work runs in the real world — Asset Vault is used inside the company every day, not just sitting on GitHub.
Trains & leads
Onboarded 10+ IT technicians into the role. I document, mentor, and level up the people around me.
Security-minded
A self-driven cybersecurity track means I think about failure modes and attack surface, not just features.
Bilingual
Fluent in English & Arabic — comfortable supporting and communicating across teams and regions.
Career & milestones
IT Technician Specialist — Rainbow Apparel
Build, deploy & support POS, Cisco networks, Inseego & peripherals across 867 stores. Built ~200 stores A→Z; trained 10+ IT techs.
Inventory & Systems Analyst — Pickle Works
Secured warehouse inventory in Oracle NetSuite with role-based access, barcode workflows & data-integrity safeguards.
Cybersecurity Track
Packet analysis, Wireshark/tcpdump, vulnerability checks & tools like Packet Analyzer — a self-driven track, separate from the day job.
B.S. Computer Science — CSI / CUNY
Computer Science degree from the City University of New York.
Flagship — Asset Vault
One source of truth for 1,000+ company devices
The problem. Technology assets — registers, switches, connectivity, peripherals — were spread across an 867-store footprint with no central inventory or ownership trail.
What I built. A full-stack asset & device management platform: role-based access, live device tracking, and operational visibility from one dashboard.
The result. Adopted internally — 3 admins now manage 1,000+ devices with clear accountability instead of scattered spreadsheets.
