I'm a Senior Product Manager at Microsoft, working on platform and developer experience for the M365 suite — most recently leading the rehoming of the Experience and Devices stack into new sovereign clouds, with all the air-gapped, data-sovereignty, and infrastructure-as-code complexity that brings. Before pivoting into tech product, I spent close to seven years at ABB designing high-voltage products in the Power Grid division. That mix — six years in physical product engineering, six in enterprise software — shapes how I think about reliability, constraints, and what it actually takes to ship.
Work
Below are some of my recent projects. Please request for the complete walkthrough of the locked projects.
01
Modular AI Chatbot Platform
Built a progression of chatbot implementations exploring how conversational AI evolves from basic prototypes to feature-rich systems with memory, tools, and database integration.
02
Podcast RAG System with Vector Search
Built a production-grade RAG system implementing automated podcast processing, vector embeddings, and semantic search to enable conversational Q&A over podcast content.
03
Voice Assistant with Persistent Memory
Built a phone-based AI voice assistant implementing conversation memory persistence to explore the technical challenges of stateful conversational AI systems.
04
AI Networking Assistant with Semantic Matching
Built an AI-powered professional networking system combining voice interaction, vector search, and automated call initiation to facilitate professional connections.
05
Autonomous Job Search AI Agent
Built an autonomous AI agent implementing multi-step agentic workflows for automated job search, content analysis, and personalized recommendations.
06
MCP Workspace Automation Agent
Built an autonomous AI agent using Model Context Protocol to connect Jira, Slack, and Notion, enabling natural language commands to execute multi-step workflows across productivity platforms.
Thoughts & Ideas
Notes on platform product, developer experience, sovereign cloud constraints, and what hardware engineering teaches you about software.
Sovereign Clouds Are A Trust Problem, Not A Tech Problem
Developer Experience Is A Product, Not A Feeling
What Designing High-Voltage Products Taught Me About Software
Experience
12+ years across hardware product engineering and software product management — from high-voltage power grid design at ABB to platform product at Microsoft.
Reliability isn't a feature you add at the end. It's a constraint you design into the first sketch.
Stack
The tools I rely on to spec, ship, and operate platform products — from cross-team planning to developer-experience and infra-as-code work.
in short
6 years at Microsoft on platform product, sovereign clouds, and developer experience for M365
