Over the past five years I've designed and delivered production-grade systems across global coworking platforms, telecom automation, enterprise sales tools, and voice-enabled multi-agent AI. I own delivery end-to-end — from React / Next.js / Angular frontends to NestJS, Java & GraphQL services on AWS with Kafka underneath.

On the AI side, I design agentic systems — LLMs, RAG with Pinecone, tool-based retrieval workflows built on LangGraph — and I've led third-party integrations with Stripe, Salesforce, HubSpot, Twilio, and Payrix to move real business workflows.

I'm a published researcher with peer-reviewed work in deep learning, NLP for low-resource languages, and computer vision for crisis response (ISCRAM 2021, Virginia Tech). I think about AI as a tool with societal impact — not just a capability spec.
