Chapter 02About
Building AI agents that actually ship
I'm a Full Stack AI Engineer building financial research AI agents — production systems that pull live market data, reason through financials, and generate analyst-grade reports, fully automated.
Currently at Spiral Kite Labs, I own the full stack: LangGraph agent architecture, LangChain tool integrations, FastAPI backend, Google Cloud Run infrastructure, and the React frontend that makes it usable.
When you're the AI + DevOps + backend + frontend person at a startup, you stop thinking in layers and start thinking in outcomes.

Your business deserves a better website.

Featured client
Live · 2026The Birder's Inn
39-room family lodge · Bharatpur, Rajasthan
A family-run lodge 200 m from the gate of Keoladeo National Park, run by resident naturalists. The new site tells the founder's story, sells the park as much as the rooms, and turns visitors into enquiries — by form, WhatsApp, phone or email.
- Full-bleed video tour with a sarus crane call you can play
- Rooms, tariff and enquiry flow — no booking engine fees
- Park guide, bird checklist and excursions — the pages birders actually search for
- WhatsApp, call and Google Maps directions one tap away on mobile
- Accessible: skip-to-content link and large, readable type
01
A new website
For hotels, homestays, clinics, restaurants and shops that need a proper home online. Designed around your business, written to be read, built to load fast on a phone.
02
A redesign
Your site works but looks 2012, breaks on mobile, or nobody can find the phone number. I rebuild it modern and fast, and keep what your customers already know.
03
Enquiries that reach you
Contact and booking enquiry forms that land in your inbox, WhatsApp and call buttons, Google Maps directions — so a visitor becomes a conversation.
04
Found on Google
Page titles, structured data, a sitemap, speed fixes and a Google Business Profile that matches your site, so people searching nearby actually find you.

Don't take my word for it.
I had the privilege of mentoring Suryansh, and I've been genuinely impressed by his technical expertise and problem-solving abilities. He's highly skilled in web development, with a strong grasp of Next.js, React.js, and JavaScript frameworks, and he has hands-on experience working with OpenAI technologies and AI/ML applications.
Suryansh approaches challenges with a clear, analytical mindset, consistently delivering thoughtful and effective solutions. His dedication to learning, coupled with his ability to share knowledge and collaborate, makes him a standout professional. I'm confident he'll excel in any role he takes on.
