Helping manufacturing and industrial teams build scalable CPQ, quoting, pricing automation, quote generation, proposal generation, and quote-to-cash systems that actually work in real sales operations.
Experience working with CPQ platforms including Salesforce CPQ, Revenue Cloud, Oracle CPQ, Apttus CPQ, custom product configurators, and pricing automation solutions.
Verticals: industrial equipment, HVAC & mechanical contractors, contract manufacturing, building materials, engineered products, custom assemblies, field services.
Where I've helped:
Spreadsheets → structured quoting & pricing automation
Moved pricing logic, product configuration rules, pricing configuration, quote generation processes, and approval workflows out of Excel into scalable CPQ and quote management systems sales reps can actually use without breaking pricing.
Homegrown tools → maintainable quote-to-cash systems
Preserved existing business logic while removing single-developer dependency and improving maintainability, quoting workflows, sales operations visibility, CRM automation, and RevOps processes.
Document builders (PandaDoc, Qwilr) → automated proposal generation
Connected configuration, pricing engines, CRM data, Salesforce CRM, and ERP systems so quotes, proposals, SOWs, and sales documents generate automatically from rules instead of manual assembly.
Heavy CPQ (Salesforce CPQ, Oracle CPQ) → right-sized implementation
Simplified existing CPQ setups, pricing workflows, quote generation processes, product configuration models, and product configurators — or replaced overengineered systems with tools that better match how the sales team actually sells.
Quote-to-cash workflow setup end-to-end
Quotes → proposals → contracts → e-sign → sales orders → fulfillment
Built full document automation flows with branded proposal generation, contract generation, approval routing, e- sign integration (DocuSign, PandaDoc, native e-sign), and downstream Sales Order / Purchase Order automation.
Approved quotes flow directly into fulfillment without manual re-entry, duplicate data entry, pricing mismatches, or version control issues between sales and operations.
Experience with:
CPQ, Configure Price Quote (CPQ), Salesforce CPQ, Revenue Cloud, pricing automation, pricing configuration, proposal automation, sales quoting, quote generation, proposal generation, RevOps workflows, Quote to Cash (QTC), sales document automation, CRM automation, Salesforce CRM, Salesforce Sales Cloud, product configuration, approval workflows, contract management, ERP/CRM integration, API integration, subscription pricing, dynamic pricing, sales operations, and quote-to-cash processes.
Not sure where to start? Send a quick overview of your current quoting process, pricing workflow, quote generation process, CPQ implementation, or proposal generation setup — I’ll take a look and share what I’d improve, no commitment required.

Need a senior architect who can build it, scale it, and make it beautiful, with AI woven through the whole thing instead of bolted on the side? That's what I do.
I'm a principal full-stack architect and polyglot engineer, 15+ years taking products from idea to production across fintech, health-tech, cybersecurity, blockchain, defense, and AI. $500K+ earned, 6,000+ hours, 5.0 rating. I run Claude Code as my daily execution layer, which is how I ship in weeks what used to take quarters, without the quality dropping.
💡 Work clients know me for:
- A $500M real-time fintech trading platform (web + mobile)
- A $100M real estate CRM built from scratch; the firm was acquired by Cushman & Wakefield
- Solana indexing infrastructure handling $1–3T in daily transaction volume
- A live algorithmic quant trading platform running real money on a tier-1 broker
- Federated-learning threat detection for an AI cybersecurity platform
- Solo-replaced a 10-developer offshore team on a national assistive-communication app
🤖 AI / LLM, where much of my recent work lives:
- Production LLM systems with structured outputs, guardrails, and audit logging in regulated fintech
- Multi-model pipelines (Claude, Whisper, Gemini, OpenAI, ElevenLabs) chosen deliberately for cost, latency, and accuracy
- MCP and agentic tooling, with official Anthropic certifications behind it
- A production AI agent and grounded voice-and-chat assistant on frontier models (Gemini, Claude, GPT), with real tool-calling into live equipment data, RAG over the actual manuals, a scorer, and an adversarial grounding eval harness that gates every deploy so it cannot hallucinate to users
- Architecting specialized-model training on proprietary field data: fine-tuning small open models (Llama/Qwen) for domain tasks like fault diagnosis and failure prediction, with labeled eval sets and an eval-gated deploy pipeline
- The discipline that keeps AI output reliable and affordable in production, not just impressive in a demo
🛠 Stack:
- Full-stack: TypeScript/React/Next.js, Node/Deno, Python, Go, Rust, Ruby/Rails, PHP/Laravel
- Mobile: Flutter, React Native, Swift, Kotlin
- APIs & data: GraphQL, REST, PostgreSQL, MySQL, MongoDB, Redis
- Cloud & infra: AWS, GCP, Supabase, Docker/K8s, CI/CD
- AI: Claude, Gemini, GPT, MCP, multi-model orchestration
- Security: PCI DSS remediation, federated learning, RLS/RBAC, signed webhooks
🎯 Clients hire me when:
- They're launching something ambitious and want it architected right the first time
- Their legacy codebase is a mess and they need someone who can inherit it and stabilize it fast
- They want AI built into the product correctly, by someone who's shipped it in production
- They want someone who thinks like an engineer, a strategist, and a founder
I also direct and design large-scale sculptures and immersive environments. Fluent in product vision, UX/UI, and creative direction, with experience in Rhino3D, Unity, CAD, TouchDesigner, and Adobe. Request my design portfolio directly if you're curious.
📩 Message me and tell me what you're building. I'll tell you how I'd make it better.

You're building something with AI, an agent, a SaaS product, a voice bot, or an automation system. You need it shipped correctly, not just "working."
I'm Kundan, an AI engineer with 10+ years of software development experience. I've delivered 200+ digital products across 50+ industries from AI agents and RAG systems to SaaS MVPs and mobile apps.
What I actually build:
→ AI Agents (LangChain, LangGraph, CrewAI, AutoGen, OpenAI Assistants)
→ Voice AI Systems (VAPI, Bland.ai, ElevenLabs, Twilio)
→ RAG pipelines (Pinecone, Qdrant, Weaviate, pgvector)
→ SaaS MVPs (Next.js 14, Supabase, Stripe, Vercel, shipped in 45 days)
→ React / React Native apps (production-grade, TypeScript, tested)
→ Python backends (FastAPI, Django, LangChain integrations)
→ AI Chatbots (custom trained, multi-channel, CRM integrated)
What makes this different:
I don't hand you a demo and disappear. Every project includes architecture design, clean handover documentation, and 30 days of post-launch support. I personally handle every discovery call and solution design, you always talk to the engineer, not a PM.
One recent example: Built a production AI chatbot platform (Aionsoft) now serving businesses across multiple industries, with a full backoffice for training, analytics, and bot management. Delivered in under 8 weeks.
