I build voice-first AI products and multi-agent systems. With 5+ years of experience in AI/ML engineering, I have experience in Conversational AI, Voice AI, and Multi-Agent Systems.
My focus is on building intelligent systems to change the way we communicate with computers and create more personalized AI experiences that adapt to individual users and business needs.
- Build voice-first AI products with real-time streaming (WebSocket, STT/TTS)
- Design multi-agent systems with Google ADK and LangChain
- Ship end-to-end AI applications from prototype to production (GCP, Cloud Run)
- Develop Chrome extensions with AI integration
- Create RAG pipelines and LLM-powered applications
The Challenge: In a 4-hour sprint, our team tackled a real sales pain point — companies receive tons of inbound calls daily, with sales reps wasting valuable time reviewing call transcripts in CRMs, often spending ~5 minutes per contact just to figure out if a lead is worth pursuing.
Our Solution: Built an AI-powered sales-call filtering system (cheekily named "Legit or Sh*t" by the team 😅) that automates the entire lead qualification process using a two-layer AI system that transcribes calls, adds real-time company context, and intelligently classifies them as potential leads, spam, or uncertain.
Technical Implementation:
- Workflow 1 (Automatic): Triggered in real-time during live calls, instantly labeling leads before they enter the CRM system
- Workflow 2 (Manual): CRM-integrated batch processing to label and filter existing contacts at scale
Impact: Sales teams can save 1000+ hours annually and cut operational costs by ~50% by filtering out low-value calls before they reach the CRM.
🏆 Outcome: Won the hackathon for innovative approach, rapid execution, and demonstrable business value in just 4 hours!
Oprina - Conversational AI Avatar Assistant
Built a revolutionary voice-powered AI assistant combining conversational intelligence with interactive avatar technology. The platform transforms email management, calendar scheduling, and productivity tasks into natural voice conversations.
🏗️ Architecture: 5-component microservices (Frontend, Backend, AI Agents, Database, External APIs) with specialized Email and Calendar agents powered by Google's Agent Development Kit and deployed on Vertex AI.
🛠️ Tech Stack: Google ADK, Vertex AI, React 18 + TypeScript, FastAPI + Python, Supabase, Google Cloud Run, HeyGen Streaming Avatars, Gmail & Calendar APIs, Speech-to-Text & Text-to-Speech
🎯 Outcome: Didn't win, but gained incredible experience building and deploying a complete platform in under a month!
