Build an AI based Saas platform for personal coaching, goal tracking and community building. Working with Debojyoti and Dipanka was an absolute pleasure. They make a fantastic team—focused, fast, and deeply thoughtful in their approach. We built a product together in record time, and what initially drew me to them was their strong design sensibility. What made the project truly successful, though, was their collaborative mindset and clear, consistent communication. Whether you’re building a brand-new MVP or iterating on an existing product, I wouldn’t hesitate to recommend them.

About Me

I'm an AI systems architect and full-stack engineer who builds AI voice agents (Vapi, LiveKit, Retell AI), multi-agent systems (LangGraph, CrewAI), and support automation that actually ships to production. My systems typically automate 60–80% of routine support tickets and cut response times from hours to seconds.

I was previously CTO at ATOZDEBUG, where I led the team building Blubuddy (a real-estate AI support bot handling hundreds of live queries) and SmartInbox (an AI email triage system that cut manual sorting by 70%).

Technical Background

AI Voice & Telephony:
Vapi.ai, LiveKit, Retell AI, Bland AI, Pipecat, Synthflow, OpenAI Realtime API. Audio/speech: Deepgram, ElevenLabs, Polly, Whisper, PlayHT. Telephony: Twilio, SIP trunking, live transfers, call recording, SMS fallback.

Autonomous Agents:
LangGraph, CrewAI, AutoGen, OpenAI Swarm, LlamaIndex, MCP. Automation glue: n8n, Make, Zapier AI, Flowise, LangFlow, StackAI. Custom tool-calling, database actions, webhooks.

RAG & Knowledge Systems:
Pinecone, Qdrant, Weaviate, ChromaDB, FAISS, Milvus, pgvector. Advanced/Graph/Hybrid RAG with LlamaIndex and LangChain. Models: GPT-4o, o1, o3-mini, Claude 3.5 Sonnet, Gemini, LLaMA 3, Mistral, DeepSeek.

Fine-Tuning & Optimization:
PEFT, LoRA, QLoRA, RLHF, DPO, Unsloth, Axolotl, HuggingFace. Inference: vLLM, TGI, Ollama, llama.cpp, Groq, AWQ, GPTQ, GGUF. Monitoring: LangSmith, Langfuse, TruLens, DeepEval, Ragas.

Backend & Infra:

Frontend:
React, Next.js, TypeScript, Vue, Tailwind. Custom AI chat widgets, admin panels, analytics dashboards.

What I Build
AI voice receptionists — 24/7 call handling with instant booking through your calendar system
Support ticket automation — custom RAG agents wired into Zendesk, Intercom, or your website's chat widget
Email triage assistants — auto-sort, tag, draft, and escalate
Multi-agent research pipelines — web scraping, PDF analysis, report generation
Private enterprise AI — dashboards, audit logging, self-hosted open-source LLMs

Message me with your business type and where things are breaking down — I'll tell you honestly whether chat, email, voice, or a hybrid setup makes sense before you place an order
