Joel
Founder, Lead Developer & Lead Security Architect
Joel is the technical foundation of VivianOps. Holding CompTIA Security+ (SY0-701) and Network+ certifications along with Microsoft’s Azure AZ-900 and a Python full-stack development certification, he brings both the credentials and the hands-on experience to back them up. He spent years in IT support at a Kansas City-area fiber internet provider, troubleshooting complex network issues, writing Python and PowerShell automation, and working alongside field technicians across rural multi-site deployments. He left to build VivianOps full-time.
At VivianOps, Joel leads product development, IT architecture, and infrastructure. He designed and built the company’s internal AI agent platform, applying a full threat model using MITRE ATT&CK and NIST frameworks, identifying and mitigating AI-specific attack vectors including prompt injection, memory poisoning, WebSocket origin bypass, and Unicode spoofing in approval prompts. That disciplined engineering approach isn’t bolted on after the fact — it is part of how VivianOps builds dependable software and IT systems.
He maintains a home enterprise lab built to professional standards — VLAN-segmented networking, a self-hosted SIEM for log ingestion and threat detection, DNS-level filtering, and a dedicated firewall for traffic control and network boundary enforcement. The AI agent platform runs in its own isolated network segment with strict outbound-only access. This isn’t a hobby setup — it’s a working security environment he uses to stay sharp and test real techniques.
Beyond the lab, Joel actively pursues offensive security skills through TryHackMe — working the SOC, Web Fundamentals, and Jr. Penetration Tester paths, completing CTF rooms in network exploitation and privilege escalation — and maintains an active HackerOne bug bounty hunter account working through real-world vulnerability disclosure programs. He completed the intensive Centriq IT Career Training cybersecurity program in Kansas City and holds a Python full-stack development certification.
When Joel says VivianOps owns its own infrastructure and never sells your data, it’s not a marketing line. He built it, secured it, and threat-modeled it himself. That’s who’s running this company.
Day to day he builds: GovGopher’s crawling and extraction pipeline, Tenderloin’s backend and mobile app, and every client project the company ships. Python, FastAPI, PostgreSQL, React Native, and the infrastructure underneath all of it.
