Edge Network

Objective: Architect a high-performance, secure web environment with zero manual deployment overhead and maximum search engine visibility.

Execution: I migrated the core application from an Expo React Native shell to a standard Next.js static export. To automate operations, I configured a GitHub Actions YAML workflow. Upon every code push, the pipeline provisions an Ubuntu runner, installs dependencies, compiles the React Server Components into static HTML, and securely authenticates with Microsoft Azure using a deployment token. Azure Static Web Apps then distributes the pre-rendered artifacts across its global edge network.

Outcome: A 100% automated CI/CD pipeline that eliminates server cold starts, neutralizes backend vulnerability vectors, and scores highly on Core Web Vitals for local SEO targeting.

Low-Voltage Infrastructure & Signal Routing

AV & Physical Networks

Engineered reliable residential and commercial physical layer installations. Implemented active balun transceivers to transmit uncompressed high-definition HDMI video signals across long-run Cat5e/Cat6 twisted-pair cabling, overcoming standard HDMI distance attenuation. Deployed and routed centralized multi-channel DVR security camera arrays with localized power distribution.

Applied Tools & Methodologies

  • ›HDMI-over-Cat5/Cat6 Balun Extenders (Active TMDS signal conversion)
  • ›Closed-Circuit Television (CCTV) & DVR/NVR multichannel security systems
  • ›Structured Ethernet termination (T568A/T568B RJ45, patch panels, keystones)
  • ›Residential AC line voltage installations (GFCI, standard receptacles, breakers)

Microelectronics Diagnostics & Hardware Repair

Device Engineering

Delivered component-level restorations on over 100 client devices including iPhones, iPads, MacBooks, and custom PC towers. Diagnostic workflows focus on isolating physical shorts, testing voltage rail tolerances, precision liquid adhesive curing, and restoring structural frame integrity without damaging internal flex cables or micro-soldered connectors.

Applied Tools & Methodologies

  • ›Mobile & Tablet Display Restoration (Digitizers, OLED/LCD panels, B-7000 adhesive bonding)
  • ›Laptop & Desktop Diagnostics (Logic board fault isolation, RAM/SSD bus integrity)
  • ›Power Management Troubleshooting (DC-in jacks, lithium-ion battery safety circuits, charging ICs)
  • ›Precision chassis assembly, ESD mitigation, and thermal paste re-application

Automotive Embedded Systems & Controller Networks

Embedded & Telemetry

Leveraged automotive systems experience to diagnose complex vehicle computing networks. Analyzed sensor inputs and actuator feedback loops communicating across vehicle CAN bus networks. Evaluated real-time engine telemetry, powertrain freeze-frame data, and electrical ground offsets to pinpoint failing micro-controllers and harness degradation.

Applied Tools & Methodologies

  • ›Controller Area Network (CAN Bus) architecture & differential signaling
  • ›On-Board Diagnostics (OBD-II) PID data logging and DTC fault isolation
  • ›Electronic Control Unit (ECU) sensor arrays (MAF, O2, TPS, Crank/Cam position)
  • ›12V automotive charging systems, starter motor relays, and parasitic draw isolation

Cloud Architecture & Full-Stack Web Systems

Cloud DevOps

Architected and deployed techbycornelius.com as a zero-cold-start static export. Designed automated deployment pipelines via GitHub Actions that compile and push pre-rendered HTML/CSS directly to Azure edge servers on every Git commit, eliminating runtime compute costs while maximizing search engine indexing speeds.

Applied Tools & Methodologies

  • ›Next.js App Router (Turbopack, Static Exports, React Server Components)
  • ›Microsoft Azure Static Web Apps (Edge routing, custom domain SSL binding)
  • ›Automated CI/CD Pipelines (GitHub Actions workflow automation, build hooks)
  • ›Serverless REST Endpoints (Payload verification, automated sheets integration)
