About Me

Driven by Technology, Grounded in Real-World Impact

With over 17 years in the IT industry, I have led engineering organisations, architected mission-critical systems, and founded technology ventures that create tangible value. As CTO at CB General Insurance Plc, I oversee the full technology lifecycle — from designing insurance core systems and cloud infrastructure to building and mentoring high-performing teams.

My approach blends strategic leadership with hands-on engineering. I believe the most impactful software comes from understanding both the technical depth and the business domain deeply — a principle I apply every day in insurtech and enterprise software.

I am passionate about scalable architecture, automation, fintech/insurtech innovation, and building products that stand the test of scale. My life philosophy: Ambition. Patience. Resilience.

Training Profile

Technical Instructor & Data Analytics Specialist

Transforming complex data into actionable business intelligence — with 17+ years of hands-on teaching experience across 1,000+ learners.

With over 17 years of experience in technical instruction and enterprise-level data architecture, I specialize in transforming complex data into actionable business intelligence. Having successfully trained over 1,000 students at reputable institutions like ANT Training Center and IT STEP Academy, I bring a wealth of pedagogical experience, particularly in managing diverse cohorts and delivering hands-on technical training. My approach bridges the gap between raw data and executive decision-making, ensuring that participants not only learn the tools but understand how to apply them to solve real-world organizational challenges.

Core Expertise

  • Data Analytics & Visualization: Extensive experience in Power BI, including advanced DAX, data modeling, and connecting disparate enterprise data sources (Oracle, Microsoft SQL Server, MySQL, Excel).
  • Advanced Excel: Deep proficiency in data cleaning, complex lookups, pivot table automation, and predictive forecasting.
  • Technical Instruction: A proven track record of teaching programming and technical concepts (C/C++, C#, SQL Server) to over 1,000 learners.
  • Enterprise Solutions: Demonstrated ability to integrate Power BI with complex core insurance systems — specifically Oracle-based Core Insurance Systems — to deliver real-time dashboards for C-suite executives (CEO, CBO, COO), tracking critical KPIs such as Quotes, Policies, and Claims.

Training Methodology

  • Instructional Approach: A balanced mix of demonstration, guided practice, and independent mini projects.
  • Mixed-Level Management: My approach involves "scaffolded learning," where core tasks are introduced for all levels, and advanced challenges are provided for senior participants to ensure maximum engagement for everyone.
  • Real-World Application: Training incorporates datasets that mirror professional organizational challenges, ensuring participants can apply their skills immediately in their workplace.
