Engineering Leader and Technical Consultant specializing in high-concurrency backend architectures, database optimization, and technology migrations. Since 2013, I have led cross-functional engineering teams, audited legacy systems, and built mission-critical payroll, fintech, and telecom platforms processing millions of transactions across Africa.
- High-Throughput Concurrency & Performance Optimization: Engineered PHP 8.x and Elixir/BEAM data pipelines, reducing payroll processing latency from 3+ hours to under 2 minutes with 99.9% accuracy at Workpay. Rebuilt USSD session routing state machines in Elixir/BEAM at Eneza Education, dropping gateway response latencies from 400ms to under 15ms.
- Fintech & Multi-Gateway Payment Ledgers: Designed double-entry bookkeeping ledgers and secure payment routing integrations (M-Pesa, MTN MoMo, Stripe, Payaza) with strict timeout idempotency to eliminate duplicate transactions.
- Technical Codebase Audits & Architecture Modernization: Conducted in-depth audits of legacy monoliths to resolve database bottlenecks and executed Strangler Fig migration strategies into decoupled services using Laravel and Elixir.
- Engineering Leadership & DevOps Automation: Mentored engineering teams, established automated testing pipelines (Pest, PHPUnit), enforced static analysis standards (PHPStan), and containerized deployments using Docker, GitLab CI, and GitHub Actions.
