DevOps Engineer & AWS Community Builder based in Nairobi, Kenya. I support, automate, and optimise mission-critical deployments on AWS — with configuration management, CI/CD, containerisation, and microservices. 5+ years building reliable cloud infrastructure.
I've spent the last 5+ years keeping critical infrastructure running across African markets, for a company that puts solar energy in homes that never had reliable power before. The stakes are real. Downtime isn't just an SLA violation; it affects field operations and revenue collection.
The work is hybrid cloud at scale: bare-metal Kubernetes on Hetzner, multi-account AWS, Rook-Ceph storage, MySQL and PostgreSQL HA clusters, GitLab CI/CD, and enough Ansible to make manual provisioning genuinely painful to think about.
Most of what I do lives at the intersection of reliability and scale: keeping distributed systems honest, building observability that actually tells you something useful, and making sure a failed OSD at 2am in Nairobi doesn't wake up a market in Mozambique.
Outside of that, I run Greentropik Consulting, where I take on infrastructure and cloud architecture work for teams that need someone who's actually fought fires, not just read about them.
I design and maintain AWS infrastructure — VPC, EC2, RDS, S3, Route 53, IAM and more — with Terraform, CloudFormation, and AWS SAM as an Infrastructure-as-Code first practice.
I build commit-to-deploy pipelines with CircleCI and Jenkins, containerise workloads with Docker and Kubernetes, and automate configuration with Ansible.
5+ years of Python across Django and Flask, plus Bash scripting. I deliver serverless applications to AWS Lambda and write the automation that ties infrastructure together.
I keep systems visible and healthy with Grafana, Prometheus, CloudWatch, Nagios, and New Relic — monitoring, logging, and alerting so issues surface before users feel them.
Open-source and personal projects spanning Kubernetes operators, platform tooling, and full-stack applications.
A Kubernetes operator that automates PodDisruptionBudget management at scale — policy-driven availability classes, label/namespace targeting, strict/flexible/advisory enforcement, automatic cleanup, and maintenance windows, with native Prometheus metrics and OpenTelemetry tracing.
A webhook integration that forwards Graylog alerts and log notifications into Mattermost channels, giving teams real-time visibility into incidents where they already collaborate.
A marketplace connecting vetted ERP specialists (SAP, Odoo, NetSuite, Dynamics) with the companies that need them — with milestone-based escrow payments, verified skill badges, and mediated dispute resolution built into every engagement.
An AI-powered study tool that turns lecture notes, slides, and past papers into flashcards, auto-marked practice questions, study notes, and a tutor that knows your material — tailored to the exam you're actually sitting (KCSE, CBC, university, or pro certs).
I'm available for consulting, contract, or full-time opportunities on short to medium notice. Whether it's cloud architecture, DevOps, or just tech talk — my inbox is always open.
