About systems
Skills & what I ship
Product engineering: desktop unlocks, edge workers, bots, and buyable software — end to end.

What I build
Available for hire · Remote — flexible hours, clear communication. Each service links to shipped proof.
Proteus simulation

7-segment display multiplexing circuit — schematic capture and live simulation.
Capabilities
What I can do
Build a shippable product
From idea to live URL with auth, billing, and a storefront path — the same loop used for Scrollshot, Keep Awake, StripePing, and WishDay.
Automate the boring edge
Workers, webhooks, bots, and alerts so payments and ops hit Telegram or WhatsApp without babysitting servers.
Desktop + web as one stack
Windows tray apps with license unlocks, paired to a marketing site and download CDN on nakeldev.com.
Marketplace & multi-tenant SaaS
Shared-seat markets, attendance systems, and tenant-aware dashboards with real auth demos.
