At Numida, I tackled the challenge of fragmented data sources and slow manual reporting processes that were delaying critical business decisions by weeks. I built a self-serve analytics infrastructure using n8n, Metabase, and Lightdash that empowered over 50 team members to generate their own reports, slashing turnaround time from 5 days to just 2 hours. By designing automated ELT workflows with dbt and Redash, I unified 15+ disparate data sources into a single analytics layer processing 2M+ daily transactions with 99.9% accuracy. Working closely with the AI/ML team, I helped deploy Taktile-powered credit risk models that improved loan approval accuracy by 28% while reducing default rates by 15%. I also integrated Pnngme data with custom Lua scripts to create a real-time decision engine that shortened underwriting from 48 hours to just 4 hours. The cumulative impact saved 200+ analyst hours monthly, enabled KES 159M in additional loan disbursements, and reduced data infrastructure costs by 35%.

My mission at Dataseal was solving a critical performance crisis where an enterprise client's business reports took 6 hours to execute, threatening SLA compliance and causing significant revenue loss from delayed insights. I diagnosed the bottlenecks using diagnostic utilities and completely rebuilt the data warehouse with an optimized Star Schema, implementing materialized views and strategic partitioning that reduced query time from 6 hours to just 8 minutes—a 98% improvement. I designed scalable multi-dimensional data models using Erwin and Power Designer that could handle a 10x increase in data volume without performance degradation. My automated ETL framework eliminated 15 hours of weekly manual processing while improving data quality scores from 73% to 97%. By conducting JAD sessions with stakeholders and leveraging Cursor AI-assisted development, I accelerated solution delivery by 45% through intelligent code generation. This work recovered KES 800K in annual revenue, enabled real-time decision-making for 200+ users, and cut infrastructure costs by 40%.

At Afripixel, I confronted a market competitiveness problem where the company was losing share due to uncompetitive pricing across 2,800+ products, with manual pricing processes taking 3 weeks per brand and eroding profit margins by 22%. I developed a Python-based A/B testing framework with statistical rigor that automatically analyzed market positioning for major brands like Simba Merchants, TP-Link, and Logitech, improving profit margins by 35% and market competitiveness by 40%. I created interactive Power BI dashboards with real-time market intelligence that reduced pricing decision cycles from 21 days to just 3 days—an 85% acceleration. By leveraging Google Analytics and Power Automate, I built a self-updating competitive analysis system that eliminated 70+ hours of monthly manual data collection. My version-controlled reporting system with automated validation checks reduced discrepancies by 20% and increased stakeholder trust by 60%. The total impact recovered KES 350K in annual profit margin, accelerated time-to-market by 85%, and improved decision accuracy by 50%.
