DevSecOps, EdTech and Infrastructure Engineering
Technical deep-dives into the Enterprise Systems, Cloud Architecture and AI innovations developed & deployed.
My Hybrid Cloud Architecture
Balancing performance and data sovereignty by splitting workloads between Cloud VPS and On-Premise Servers.
Cloudflare/Tailscale
Zero Trust / DNS
DigitalOcean
VPS Droplet
On-Premise Server
Docker Orchestration
Fig 1. Traffic flows through Cloudflare, splitting between Cloud VPS (Public Assets) and On-Premise Tunnel (Secure Data), bypassing local firewall ports.
The Strategy
This hybrid approach ensures high availability for public-facing assets (Website, LMS) via DigitalOcean, while keeping sensitive financial data (ERP) and compute-heavy AI tasks on-premise to reduce cloud costs. Cloudflare Tunnels bridge the gap securely without opening firewall ports.
My Automated DevOps Pipeline Setup
How code travels from my laptop to production with zero manual intervention.
Develop
VS Code / Localhost
Push
Version Control
Action Runner
Self-Hosted CI/CD
Build
Docker Compose
Live
Zero Downtime
Self-Healing Deployment
I implemented a custom GitHub Action that triggers on every push to `main`. The runner automatically:
- Updates source code securely.
- Installs PHP dependencies (Composer) and Node modules.
- Fixes file permission issues (
chown/chmod). - Rebuilds and restarts only the affected Docker containers.
Featured Projects
Welcome to enerd-dev engineering portfolio showcase
Accessibility Engine
Integrated Font Resizer, Contrast Toggles, Light/Dark Mode Toggle, Audio Page Narrator and Screen Reader optimization (WCAG 2.1).
MTIB Accessible Public Portal
A modern digital gateway built to serve a diverse user base. Unlike standard sites, this portal was architected with Accessibility First principles. It utilizes a Headless Architecture (Next.js + Strapi) to ensure lightning-fast page loads for low-bandwidth users.
AURA Student Assistant
Accessible Unified Responsive Assistant. A private, on-premise AI agent that empowers visually impaired students to query institutional policies using natural language.
Integration Status
Fully integrated with Public Website. LMS & ERP deep-integration currently in development.
Inclusive e-Learning
Where engineering meets pedagogy. I deployed Moodle 4.5 on Cloud VPS for high availability and customized the interface to be strictly compatible with NVDA and JAWS screen readers.
Content Engineering
Collaborating with faculty to design accessible courseware using:
RevCore Analytics
A critical Revenue Collections tool that Automates collections reporting and reconciliation of field reports data and visualizes trends in real-time. I developed and deployed for Makueni County Treasury - Revenue Directorate
VisionLink ERP
The institution's "Single Source of Truth." This modular system eliminates data silos by integrating:
- Admissions: Digital biodata and enrollment.
- Finance: Automated billing and vote-head tracking.
- Academics: Grading and transcript generation.
Systems Monitoring & Reliability
Proactive monitoring ensures 99.9% availability for all deployed systems.
Real-Time Alerts
Automated pings every 60 seconds. Instant notifications via Slack if any service degrades.
View Status PageContainer Orchestration
Visual management of the Docker Swarm. Log inspection, resource usage tracking, and one-click restarts.
