Case Studies:
Cloud Computing Project
Overview
A mid-sized enterprise based in Nairobi faced rising infrastructure costs, system downtime, and scalability limitations due to outdated on-premise servers.I led a full-scale multi-region cloud migration strategy on AWS to modernize operations, improve performance, and reduce operational costs.
The Challenge
The organization was experiencing:
High infrastructure maintenance costs.
Frequent system downtime affecting operations and customer SLAs.
Limited scalability during peak demand and traffic spikes.
Security vulnerabilities in legacy single-region systems.
Key Results
30% Reduction in annual cloud infrastructure costs.
Improved system uptime to 99.998% across core services.
Faster application performance with a 42% reduction in response latency.
Enhanced data security and automated multi-region backup compliance.
Scalable infrastructure architecture ready for high-growth regional expansion.
A showcase of projects I’ve led and delivered.
Edtech Project
Overview
A Pan-African higher education network serving over 4 million students suffered severe system lag and outages during peak exam periods. As Tech PM, I led the technical overhaul of their digital learning management platform to handle massive concurrent traffic and streamline student analytics.
The Challenge
The institution was experiencing:
Frequent platform crashes and timeouts during peak examination windows.
Sluggish video lecture streams and poor global content delivery.
Inability for instructors to track student progress and completion rates in real time.
High student drop-out rates caused by friction in the digital learning portal.
Key Results
Successfully scaled platform capacity to support 4.2M Active Learners concurrently.
24% Increase in overall student course completion and retention rates.
Zero system downtime completely achieved during high-stakes exam windows.
Real-time student engagement analytics and automated progress tracking integrated.
Optimized global CDN delivery ensuring instant, lag-free video playback.
Digital Transformation Project
Overview
An established enterprise with distributed regional offices was severely hindered by manual paper-heavy workflows, siloed legacy databases, and slow cross-departmental communication. As Tech PM, I led an enterprise-wide digital transformation to automate core processes and modernize legacy architecture.
The Challenge
The organization was experiencing:
Heavy reliance on manual paper-to-digital data entry and approvals.
Siloed legacy databases preventing cross-departmental collaboration.
Long turnarounds (up to 4 days) for executive reporting and operational sign-offs.
High operational error rates and slow time-to-market for internal initiatives.
Key Results
68% Increase in company-wide operational efficiency.
Slashed reporting and approval turnarounds from 4 days down to 15 minutes.
3x Faster time-to-market for new product features and internal workflows.
100% digital workflow adoption achieved across all operational units.
Elimination of manual paper processing bottlenecks and legacy data silos.
Cybersecurity Project
Overview
An enterprise financial and technology hub based in Nairobi faced increasing cyber threat risks, uncoordinated audit logs, and compliance exposure across distributed regional teams.I directed the end-to-end strategy to construct a centralized Security Operations Center (SOC) and enforce zero-trust policies
The Challenge
The organization was experiencing:
Limited real-time visibility into network intrusions and incoming threats.
Fragmented security logs scattered across cloud and local servers.
Sluggish threat response times measuring in hours rather than minutes.
High compliance and audit risks across regional operating hubs.
Key Results
98/100 Security Score achieved on independent third-party compliance audits.
Reduced threat detection and response time to under 3 minutes.
Zero critical vulnerabilities remaining across the entire enterprise footprint.
Centralized real-time monitoring established for all regional hub networks.
Automated security scanning seamlessly integrated into developer CI/CD pipelines.
