What I Build

Not just code — systems. From native apps talking to hardware, to cloud platforms serving millions, to AI agents that automate the complex.

01

Connected Mobile Experiences

Native iOS apps built for the physical world. Real-time BLE communication with fitness devices, wearables, and sensors — engineered for reliability, performance, and zero battery drain.

AI-Driven Agentic Workflows

Multi-agent systems that interface with APIs, process real-world data, and make autonomous decisions. Building the bridge between intelligent AI models and real hardware.

Exploring AI Systems & Agentic Workflows

My focus is on agents that don't just process text — they interface with hardware, APIs, and business workflows to create real leverage.

IoT + AI Coaching

Active

Fitness device data via BLE → agent pipeline → personalized training advice and anomaly detection.

DevOps Intelligence

Active

Multi-agent orchestration pulling GitHub, Jira, and metrics dashboards to auto-generate engineering reports.

MCP Server for IoT

Research

Building Model Context Protocol servers to give AI agents native access to BLE device APIs and sensor streams.

Tool-Augmented Assistants

Active

Claude-powered assistants with tool use — connected to databases, APIs, calendars, and internal docs.
