LumionIoT specialty
Connected-device engineering is one of my strongest lanes.
I work across the device layer, communication layer, application layer, and cloud-backed management layer. That means I can shape the experience from sensor and device behavior all the way to the dashboard, mobile app, and operational workflow around it.
Device layer
Arduino, ESP32, connected sensors, embedded workflows, hardware-aware application logic
Connectivity
MQTT messaging, device communication patterns, secure configuration flows, real-time monitoring
Application layer
React Native mobile apps, React admin portals, device dashboards, operational visibility tools
Cloud and delivery
AWS-backed reliability, scalable backend support, remote device management, maintainable production rollout
AI & Data Engineering
Transforming raw telemetry & data into intelligent action.
I build data systems that bridge real-world physical devices, automated pipelines, and AI intelligence. From custom data extraction to LLM workflows and operational analytics, I build reliable data infrastructure ready for production.
Intelligent systems
AI workflows, intelligent agents, LLM integrations, and practical model deployment with Python and modern ML frameworks.
Data engineering
Scalable ETL pipelines, structured schema design, streaming data flows, PostgreSQL, MySQL, MongoDB, and telemetry databases.
Analytics & insights
Real-time operational dashboards, IoT telemetry analysis, Power BI intelligence, and automated metrics tracking.
Production scale
Deploying low-latency AI inference and high-throughput data processing services on cloud infrastructure.
Open-source focus
Open source is part of the core engineering profile.
I approach open-source work as real engineering: reusable systems, contributor-ready structure, maintainable architecture, and developer tools that can grow with a community.
Community building
Leading OpenCorex as an open-source engineering community with technical direction, project ownership, and contributor-facing structure.
Developer tooling
Building frameworks, packages, reusable project foundations, and maintainable codebases intended to be used and extended by other developers.
