The Architect Behind
the Automation

I'm a Customer Operations Professional turned AI Automation Architect with 4+ years of experience spanning customer success, vendor management, strategic partnerships, and enterprise operations.

My career began on the front lines of customer success — leading support teams, driving revenue, and building client relationships at scale. That grounding in operations gave me a firsthand understanding of where human effort is wasted on repetitive, automatable work.

At Equinix Nigeria, I managed 40+ enterprise vendor relationships, drove $200K+ in cost savings, and recovered credits through meticulous compliance management. At AmeriCare, I built healthcare partnerships that grew revenue by 15%. Along the way, I became obsessed with a question: what if the work could run itself?

That question led me to AI. Today at Credulen, I design intelligent automation systems — RAG knowledge engines, voice AI agents, GPT-powered CRM pipelines, and conversational assistants — that do the work of entire teams, around the clock, without error.

I combine deep operational intuition with AI engineering capability. I don't just build automations — I build solutions that understand the business problem behind them.

Featured · RAG + LLM Pipeline
AI Resume Processing Automation
Problem

HR teams spending hours manually reviewing resumes, inconsistent candidate scoring, and slow pipelines causing talent loss to faster-moving competitors.

Solution

Built an end-to-end automated pipeline triggered by Google Drive file uploads. Resumes are downloaded, converted to PDF, text extracted, then passed through an AI Resume Analyzer (OpenAI Chat Model + Structured Output Parser). Qualified candidates are auto-created in ClickUp with timezone data enriched from location.
