Background & Philosophy

Bridging the Gap Between Technology & People

Helping people understand and succeed with technology has been my true passion from day one. In an era where software powers everything from neighborhood dining to global payments, the human element of technical troubleshooting is more vital than ever.

Growing up, I was constantly inundated with questions about how computers, networks, and gadgets worked. Answering those questions sparked a lifelong curiosity that evolved into a career: I didn’t just want to find the fix—I wanted to understand the root cause and empower people with knowledge.

Over the past decade, my work has spanned the full tech spectrum: from scaling residential high-speed infrastructure in the field with Cox and Bear Communications, to supporting financial workflows at PayPal, resolving mission-critical Android POS and network escalations at Toast, troubleshooting micro-market vending SaaS at 365 Retail Markets, to now managing client website lifecycles and white-label apps at DoorDash.

Beyond my day job, I have dedicated over 5 years to community volunteering at Do Space in Omaha, hosting Tech Help Tuesdays and mentoring people of all ages to conquer their technology hurdles.

Full Web & DNS Lifecycle

Proficient in domain provisioning, DNS propagation troubleshooting (A, CNAME, TXT, MX), SSL certificates, and hosting maintenance for hundreds of SMB storefronts.

Data-Driven Diagnostics & APIs

Writing SQL queries in Mode Analytics to audit operational bottlenecks, coupled with Postman API testing to diagnose payload failures across microservices.

Cross-Functional Advocacy

Partnering seamlessly with engineering, product, and onboarding teams to convert frontline ticket trends into long-term product fixes and clear internal documentation.

Systems Architecture & Engineering

Online Ordering Projects & Live Sandbox

Inspired by 8+ years in SaaS operations, POS diagnostics, and enterprise ordering at DoorDash, Toast, and 365 Retail Markets. I am building modern software systems to solve real merchant pain points: webhook payload normalization, POS ticket generation, white-label DNS provisioning, and omnichannel kitchen routing.

Real-World Problem Solving

Troubleshooting Case Studies

A deep dive into how I approach root cause analysis, cross-system isolation, and permanent resolutions.

DNS & Hosting Lifecycle DoorDash

White-Label Custom Domain & App Synchronization Outage

The Symptom:

High-volume restaurant client reported that mobile app ordering and custom storefront domains failed immediately after a merchant domain renewal.

Root Cause Investigation:

Audited DNS records across root registrar. Discovered an extraneous conflicting A-record pointing to old parked hosting, breaking CNAME routing and SSL cert renewal handshake.

Resolution & Impact:

Cleaned DNS zone files, expedited propagation via manual host header triggers, and re-provisioned SSL. Verified order transaction flow in Mode Analytics with zero ongoing client revenue loss.

IoT / POS Diagnostics 365 Retail

Payment Gateway Webhook Timeout on Unattended Kiosks

The Symptom:

Distributed enterprise micro-market vending kiosks froze during credit card reader authorization, halting hundreds of daily automated purchases.

Root Cause Investigation:

Replicated transaction payload using Postman API against staging endpoints. Identified that a card reader firmware patch altered handshake headers, tripping security firewalls.

Resolution & Impact:

Collaborated with backend engineering on a quick payload adapter. Pushed remote OS config rollbacks across affected kiosks, bringing all locations back online in under an hour.

Postman API Card Readers Remote Desktop
Network & Hardware Toast POS

Peak Dinner Hour Kitchen Printer Dropping Network Packets

The Symptom:

High-volume restaurant handheld POS devices lost connection to kitchen order thermal printers during Friday night peak rush, creating order backlog.

Root Cause Investigation:

Discovered an unmanaged guest Wi-Fi router on the same physical subnet assigning dynamic DHCP addresses overlapping with static kitchen printer IPs.

Resolution & Impact:

Isolated guest traffic into a segregated VLAN, assigned MAC-bound static IP reservations for all POS hardware, and authored a prevention guide published to the internal knowledge base.
