Bal D.

I build production AI products and full stack platforms, from architecture to deployment, not just demos. 17+ years of engineering experience. I help founders, startups, and enterprises ship AI agents, LLM apps, and SaaS platforms that work in production, with real users, real payments, and real scale. 𝗪𝗵𝗮𝘁 𝗜 𝗯𝘂𝗶𝗹𝗱 = AI Agents & Multi-Agent Systems: autonomous workflows with tool/function calling, memory, and human-in-the-loop controls = RAG & Knowledge Bases: hybrid search, reranking, GraphRAG, and semantic search over your documents and data = Voice AI Agents: real-time conversational agents for support, sales, and appointment booking = AI Chatbots & Assistants: web, WhatsApp, and in-app assistants connected to your CRM, database, and APIs = AI CRM & Lead Qualification: scoring, enrichment, and automated follow-ups = Document Processing: OCR, extraction, summarization, and classification pipelines = Full-Stack SaaS, E-Commerce & Mobile: payments, subscriptions, multi-tenant systems, and Shopify (custom themes, apps, compliance) 𝗔𝗜 𝘀𝘁𝗮𝗰𝗸 = Models: OpenAI GPT, Anthropic Claude, Google Gemini, Llama, Mistral, DeepSeek, Qwen (open-source models via Ollama, vLLM, Groq, OpenRouter) = Agent frameworks: LangGraph, LangChain, LlamaIndex, OpenAI Agents SDK, CrewAI, AutoGen, Pydantic AI, Vercel AI SDK = Protocols: MCP (Model Context Protocol), function/tool calling, structured outputs = Vector search: pgvector, Pinecone, Qdrant, Weaviate, Supabase Vector = Voice: Vapi, Retell AI, ElevenLabs, Deepgram, LiveKit, OpenAI Realtime API, WebRTC/WebSockets, Agora 𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴 𝘀𝘁𝗮𝗰𝗸 = React, Next.js, Vue, Nuxt, TypeScript, Tailwind, Node.js, Python (FastAPI, Django), PHP/Laravel, React Native, Flutter, PostgreSQL, MongoDB, Supabase, Redis, AWS, GCP, Docker, CI/CD, serverless 𝗔𝗜-𝗮𝗰𝗰𝗲𝗹𝗲𝗿𝗮𝘁𝗲𝗱 𝗱𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 I use Claude Code, Cursor, and GitHub Copilot in my workflow, with human review on everything shipped. That means faster delivery, tighter iterations, and better test coverage without cutting quality. It's also why I can prototype in days and harden for production without a long timeline. Recent work includes a payment platform with AI agents, multi-agent systems, Agora integration, EdTech/LMS platforms built from scratch with multiple third-party API integrations, healthcare applications, SaaS platforms, mobile applications, and several Shopify builds covering custom themes, apps, and compliance updates. Send me a short description of what you're building and I'll reply with a suggested approach and timeline.
