Real systems.
Real constraints.

Aging cameras, inconsistent wiring, and uneven NVR configurations made outages harder to diagnose.

Replaced failing sensors and cables, tuned Milestone and Husky recording profiles, and standardized labels, strain relief, and service documentation.

Higher uptime, fewer repeat service calls, and faster on-site diagnosis.

Critical sites needed resilient connectivity, fiber backup, and extensions to places fiber could not reach.

Provisioned, aligned, maintained, and documented Siklu 8010/2500/1200/700/600 and Ubiquiti AF-series radio links.

Stable throughput, reliable continuity, and better records for the next field visit.

Residents and visitors needed stable internet access across open-air environments.

Installed outdoor access points, wireless backhaul, weatherproof PoE power, surge protection, and serviceable enclosures.

Expanded public connectivity with infrastructure built for coastal and outdoor conditions.

Video and backhaul equipment needed continuous power where grid service was unavailable.

Calculated loads, installed dual-panel solar and sealed battery systems, wired DC-to-PoE, commissioned charge behavior, and later added wind assist.

Multi-day autonomy, clearer maintenance, and fewer truck rolls during poor weather.

Jams, wear, and miscalibration interrupted daily operations.

Performed preventive maintenance, diagnosed faults, replaced rollers and sensors, and calibrated Xi, Z, and ZT-series printers.

Lower downtime and longer useful equipment life.

Urban solar can conflict with aesthetics and produces most heavily at midday rather than commute peaks.

Developed a concept using colored vertical bifacial panels and albedo to support lighting, signage, charging, and cameras.

A city-ready pilot concept designed around morning and evening production and visual integration.

I wanted lightweight DNS filtering and secure remote browsing without another full computer.

Configured Pi-hole, a Tailscale exit node, custom services, and dependable startup behavior across small ARM devices.

Quiet, reliable local services with simple remote access.

Shipping and marketplace fees made consistent buying and listing decisions slow and error-prone.

Built a spreadsheet model for price caps, shipping tiers, marketplace fees, what-if pricing, and net payout.

Faster listing decisions and consistent margins across a growing collection.
