Field engineer for systems that stay up.
Software engineering, systems architecture, IT and cloud from Nairobi — with the evidence trail to back every claim. Here's the background, the competencies and the working method.
Engineering at Every Layer.
I don't just write code — I architect complete systems. From pixel-perfect React interfaces to containerised backend services deployed on self-hosted infrastructure, every layer is intentional.
Frontend Engineering
React • Next.js • Tailwind • TypeScript
Pixel-perfect UIs with obsessive performance tuning. Motion that feels alive. Every component, every transition — intentional.
Backend Systems
Node.js • C# • .NET • Python
APIs and services built for scale — clean architecture, reliable contracts. REST, GraphQL, and everything in between.
Mobile & Cross-Platform
Kotlin • Flutter • React Native
Native-feel experiences that are fast, smooth, and genuinely usable. From zero to app store — full lifecycle delivery.
Infrastructure & DevOps
Docker • Proxmox • Cloud • CI/CD
Self-hosted, containerised, automated. I own the stack end-to-end, from bare metal to production deployment.
Specialised Expertise.
From identity-layer security to embedded systems — five core areas where I deliver production-grade engineering.
Identity, Notification & Messaging
Notification delivery services (push, in-app, multi-channel) · Authentication flows (password, biometric) · Real-time messaging & presence · Security signals & account lifecycle
Designed and built notification delivery capabilities within an in-house ERP system, enabling real-time push notifications, in-app alerts, and multi-channel messaging across mobile and web. Implemented authentication flows including password-based login and on-device biometric verification. Built a real-time chat and messaging subsystem handling message delivery, presence, and read-receipt patterns at institutional scale.
Backend & Distributed Systems
C#, Python, JavaScript/TypeScript, C++ · API & backend service development · Queue-based architectures · Scalable, high-availability service design
Architected and developed full-stack ERP systems consolidating student records, attendance, finance, and communication workflows. Built RESTful APIs and database schemas (PostgreSQL/MySQL) serving daily operations. Developed internal automation tools and refactored database schemas cutting query response times by 15%.
Cloud & DevOps
Azure · Docker · Kubernetes · CI/CD pipelines · Bash automation · Proxmox · Resource & cost optimisation
Managed Azure cloud infrastructure end-to-end, optimising resource allocation and cutting cloud operating costs by 20%. Wrote Bash automation scripts and CI/CD pipelines that reduced deployment errors by 45% and reclaimed 15+ hours per week. Deployed and maintained containerised services using Docker and Kubernetes, improving system uptime by 50% and reducing latency by 30%.
Reliability & Live-Site Operations
Incident triage & escalation · Post-incident reviews · 99.9% uptime delivery · Monitoring & health checks · Enterprise-grade SLAs
Delivered 99.9% uptime on mission-critical systems through proactive monitoring, scheduled maintenance, and disciplined, fully documented incident response — including root-cause analysis and follow-up action tracking after every incident. Designed a high-availability storage architecture on TrueNAS supporting 10TB+ of institutional data with redundancy and failover patterns.
Systems Thinking Across the Stack
Embedded/hardware-adjacent software · Cross-platform app development · Product-minded engineering · Real-time/interactive systems
A wide personal project portfolio spanning media platforms, embedded/hardware-adjacent software (Arduino, USB & serial protocols, GPU firmware), mobile apps, and game development. Brings an AI-first mindset with a focus on reliability, observability, security, and continuous modernisation, thriving across cross-functional and cross-team engineering groups.
Academic Foundation.
Umma University
Full Toolbelt.
Languages, platforms, and infrastructure I work with — from cloud down to microcontrollers and USB peripherals.
Stack Fluency.
Proficiency across my primary languages and frameworks. Depth over breadth — every tool here is production-ready.
My Tech Environment.
The platforms and tools I work with daily — from bare metal to cloud. Every environment, optimised for performance.
Hire Joseph as an engineer.
Full-time or contract engineering depth in backend systems, cloud and reliability. Start with the résumé and the work ledger.
Bring a technical problem.
Software, IT & infrastructure, AI & automation, custom PCs and technical leadership are the commercial side of the same skill set.
Curious whether your problem fits?
The free first conversation settles it — about the work, the evidence, and what's realistic for your situation.
