What I do

A full product studio, in one freelancer.

From the first Figma frame to the live store, the chatbot replying at 2am, and the n8n flow tagging your customers — I handle the entire stack so you don't have to coordinate five different vendors.

01 / DESIGN

Brand & product design

UI/UX in Figma, design systems, conversion-focused storefront design that respects your brand.

eCommerce automation

The store runs itself — you read the reports.

Stop pasting tracking links into WhatsApp and replying to "is this in stock?" at 11pm. I build the agents and flows that handle every routine touchpoint.

End-to-end commerce automation

I architect AI agents grounded on your catalog and policies (RAG with LangChain), wire them into n8n workflows, and connect every system you already use — Shopify, Razorpay, Cashfree, Meta, WhatsApp Business.

RAG support agent

Answers product, policy and order questions on WhatsApp & web — never hallucinates.

Order & cart flows

Confirmations, shipping updates, abandoned-cart recovery on WhatsApp via n8n.

Returns & CX desk

Auto-triage tickets, draft replies, escalate only what humans need to see.

Catalog & ads sync

Inventory → Meta catalog → Pixel/CAPI → ads, on a single source of truth.

Common questions

Everything you might ask.

How long does a project take?

A landing page or simple site: 1–2 weeks. A full Shopify or React storefront: 3–5 weeks. A custom MERN app or RAG agent build: 4–8 weeks. Timelines depend on content readiness and feedback turnaround on your side.

What does a project cost?

Landing pages & simple sites start around $200–$800. E-commerce stores (Shopify, Woo) range $800–$3,000. Custom React/PHP web apps $2,000–$10,000. Mobile apps $3,000–$15,000. AI/automation projects are scoped separately based on data volume and integrations.

Can I make design changes during the build?

Yes — minor edits and copy/visual revisions are part of the design phase. Major structural changes after sign-off may extend the timeline and cost; I'll always flag the trade-off before doing the work.

Do you handle the chatbot & automation alone?

Yes. I personally architect, build and deploy the agents — using LangChain, RAG, n8n and OpenAI. I host them on Firebase / Supabase / your VPS, and hand over a clean dashboard plus monthly retainer if you want me to keep tuning.

Are you really a Meta & Shopify partner?

Yes. I work with Meta's Business Partner program for ads & CAPI setup, and I'm a Shopify Partner — meaning early access to themes, dev stores and the partner dashboard for staging.

Do you offer support after launch?

Always. Every project ships with 30 days of free support. After that, you can either pay-per-task or take a monthly retainer (recommended for stores doing daily revenue).
