Most AI vendors give you working code. I give you working code and a business case for why it's built the way it is.
I'm an AI systems architect with an MBA from IIM Ahmedabad — which means I don't just build LLM pipelines and voice agents, I build them with commercial outcomes in mind: cost-per-transaction, throughput at scale, accuracy thresholds that actually matter to your P&L.
What I specialise in:
AI Voice Agents (inbound/outbound automation, CRM integration, multilingual support)
LLM & NLP Pipelines (classification, extraction, fine-tuning at millions of records/day)
Intelligent Data Systems (confidence routing, self-learning lookup mechanisms, hybrid retrieval)
I've designed and delivered production systems for enterprise clients in trade intelligence, real estate, and B2B SaaS — handling data volumes exceeding 5M rows/day with three-tier confidence routing and sub-second response requirements.
The MBA isn't a line on a résumé. It's why my clients get a solution architecture review alongside the code — so the system we build today doesn't become technical debt in six months.
I work best with teams that:
Have a real business problem, not just a vague "AI project"
Value a senior thinking partner, not just a pair of hands
Want production-grade output, not a prototype that dies in staging
If that's you, let's talk. I typically open with a 20-minute scoping call — no pitch, just clarity on whether this is the right fit.
A few things clients consistently note:
"Darshan thinks like a product manager and builds like an engineer"
"He flagged problems we hadn't anticipated before we'd even started building"
"First freelancer who gave us a proper ROI framing before writing a single line of code"
Available for fixed-price engagements and long-term retainers. Response time: within 4 hours.
