Professional Experience

Platform Migration

Own the GCP IoT platform now serving 70,000+ devices and 10,000+ user accounts at 99.999% uptime, after a zero-downtime live migration from Xively

IoT Architecture

Designed an event-driven platform for smart electrical devices handling 100+ events per second with secure device communication

Cloud Infrastructure

Built and operated services on GCP using Kubernetes, Cloud Functions, Redis, PubSub, and Cloud SQL for scalability and resilience

Data Lifecycle & Cost Control

Controlled Cloud SQL storage and associated cost growth with monthly PostgreSQL partitions, archival, and fast removal of expired time-series data; also reduced low-value Cloud Logging volume

Keyless Cloud Identity

Implemented Workload Identity Federation for GitHub Actions and GKE workloads, replacing long-lived service-account keys with short-lived, least-privilege access

Backend & Integration APIs

Developed TypeScript and Node.js REST APIs, event-driven services, and authorised third-party integrations for device data, control, and status events

Frontend Applications

Developed the React/Redux admin portal and a focused Next.js invitation-accept portal for customers and installers

Voice Integrations

Engineered and certified Google Assistant and Alexa smart-home integrations, expanding ecosystem compatibility

Reusable Libraries

Created unit-tested TypeScript and Node.js libraries for shared functionality, reducing duplication and speeding delivery of new features

CI/CD & Kubernetes Configuration

Built once to a shared Artifact Registry, promoted the same artifacts across environments, and managed Kubernetes configuration with reusable Kustomize bases and overlays

Solution Design & Documentation

Documented architecture, interfaces, decisions, and test cases before implementation to improve design quality and knowledge transfer

Firmware Delivery

Built an OTA firmware CDN and certificate-management workflow for memory-constrained IoT devices

Initial Platform Development

Initially developed product functionality based on Xively IoT platform with REST API for apps and admin dashboard

Cloud Migration to GCP
