Senior Infrastructure Engineer · Nairobi, Kenya
Backend & Infra Engineer
I design, build, and run production-grade backend systems and cloud infrastructure. Go-first. Linux-native. Docker-everything. Built SaaS, fintech, and automation platforms that handle real money, real users, and real uptime requirements — from architecture through deployment.

What I Actually
Know How to Do
Primary Language
Go — Production-Grade
Fiber framework, REST APIs, background workers, WebSockets, graceful shutdown, context propagation. Not tutorials — production multi-tenant apps handling payments, scheduling, real-time notifications.
Infrastructure
Linux Server Operations
Provisions, hardens, and maintains production Linux environments. Zero-downtime deployments. Nginx reverse proxies. SSL/TLS A+ ratings. UFW + Fail2Ban. Backup pipelines and disaster recovery.
Containerization
Docker — Full Lifecycle
Multi-stage builds, optimised images, Compose orchestration, container networking, volume management, health checks, and zero-downtime container swaps in production. Not just docker run.
DevOps & Automation
CI/CD Pipelines
Cut deployment time from 30 min → under 5 min via GitHub Actions. Full pipeline: build, test, lint, containerise, deploy, health check, rollback. Consistent, repeatable, no manual steps.
Data Layer
PostgreSQL & Caching
Schema design, indexing strategy, query optimisation, connection pooling (pgx), migrations. Redis for caching and pub/sub. Production backup automation and point-in-time recovery planning.
Security
Hardening & Compliance
Fortinet-certified. Implements A+ SSL, strict CSP, HSTS preloading, OWASP mitigations, SPF/DKIM/DMARC, FortiGate/FortiAnalyzer, and vulnerability scanning on production infrastructure.

SalonBook
SalonBook is a production-style SaaS platform designed to digitize salon operations through WhatsApp automation. It enables customers to book appointments, receive reminders, and make payments without requiring a mobile app.
The system is built using a multi-tenant architecture where multiple salons operate on a shared infrastructure while maintaining strict data isolation. It integrates WhatsApp messaging workflows, payment processing, and backend scheduling logic into a unified system deployed on Docker-based infrastructure.
