What I've built
Featured Projects
Magistrala IoT Platform
Browser-based interface for managing IoT systems — provision devices, configure real-time rules, monitor alarms, and build dashboards without writing code.
Magistrala Website
Documentation and marketing website for Magistrala, an enterprise-grade open-source IoT platform powering smart energy, water metering, and agriculture solutions.
FluxMQ Dashboard
Dashboard for managing FluxMQ, a high-performance open-source message broker supporting MQTT, AMQP, and CoAP with sub-10ms latency at 300K–500K msgs/sec.
Ultraviolet Website
Marketing and content hub for Ultraviolet, a confidential computing startup. Built with Astro and Tailwind CSS for blazing-fast static delivery, featuring a reusable component architecture and optimized imagery.
Propeller UI
Maintained the product website and UI for Propeller, a WebAssembly workload orchestrator for the Cloud-Edge continuum — enabling portable, sandboxed app deployment from cloud servers to edge microcontrollers.
IoT Client SDKs
Authored and maintained official client libraries for Magistrala IoT platform in TypeScript and Python, enabling developers to integrate device provisioning, messaging, and data pipelines across language ecosystems.
