Manual handoffs keep stealing attention
Email, documents, scheduling and data movement depend on repeated copying, checking and follow-up.
AI Systems Architect · Automation · Integration · Agent Security
AI systems that take work off your plate—without taking judgment out of your hands.
I’m Frederick Nwokobia, an AI systems architect with 30 years in security and financial services. I design workflow automation, application integrations, AI assistants and agent systems that are documented, auditable and built around how your organization actually works.
Security-minded builder. Commercially aware. Hands-on from architecture through implementation.
01Selected Systems
Systems I have built and put to work.
My work spans products, operating platforms and client systems. The common thread is simple: connect the work, keep the boundaries clear, and make every important action inspectable.
Open source · Practical agent security
ClawNex
Self-hosted protection for teams without enterprise security budgets. I built ClawNex to turn 30 years of security practice into accessible controls for modern agent harnesses: traffic inspection, custom DLP rules, PII protection, prompt-injection detection and an evidence trail—with no licence fee.

Data sovereignty · Owned business platform
Groovefellows Stack
A working pattern for data sovereignty—not residency alone. Open-source business systems, operator-controlled infrastructure and encryption keys, plus local AI where sensitivity requires it, keep control and portability close to the business while making maintenance, security and recovery an explicit responsibility.

02Where I Help
When important work is trapped between tools.
AI is useful when it removes friction from real work. I help organizations find the right intervention—whether that is an automation, an integration, an assistant, an application or a better control boundary.
Your AI tools do not know the work
Outputs look polished, but lack your operating context, decision rules, systems and review habits.
Agents can act, but nobody can explain the risk
Access, data movement, model traffic and evidence are unclear once autonomous systems enter the workflow.
03Expertise
From diagnosis to a governed working system.
I work across the full system: business process, application boundary, model behaviour, integration surface, security control and operating handover.
Workflow automation & integration
Connect the systems you already use and remove repeated movement between inboxes, files, business applications and approvals.
APIs · Events · OrchestrationAI assistants & agent systems
Design assistants around context, tools, judgment calls and review points instead of placing a generic chat interface on top of the work.
Context · Tools · EvaluationAgent security & governance
Define trust boundaries, inspect model traffic, preserve evidence and make autonomy understandable to operators and leaders.
Policy · Audit · ClawNexAI-native applications & workspaces
Turn business problems into secure applications and controlled environments where people and AI agents can work together.
Apps · Delivery · SovereigntyArchitecture & advisory
Evaluate what should be built, what should be bought, where risk belongs and how to prove value before scaling.
Strategy · Review · Due diligenceThe operating principle
Autonomy needs evidence, boundaries and review.
Nothing important should reach production on confidence alone. Every system needs clear inputs, expected behaviour, review points, failure handling and a record of what happened.

Experience that changes how I build
Thirty years where failure has consequences.
My career runs from hands-on infrastructure and forensics through global banking security and into AI systems architecture. The throughline is verification: understand the operating reality, make the boundary explicit and prove the system before people depend on it.

04The Ecosystem
One relationship, one delivery path, one connected body of work.
This site is where you can learn how I think and start a conversation. When that conversation becomes a project, ProBizSystems handles the proposal, delivery and ongoing support. ClawNex is the open-source security product. The Groovefellows Stack is the working sovereignty pattern.
