One engineer, the full loop
The same person takes the brief, designs the system, writes the code, ships it, and answers the support thread. No account-manager layer between you and the work.
About · Sumit Bansal
One engineer. Twelve-plus years shipping things that had to work.
I'm Sumit Bansal. NextFlow Builder is the studio I run — automation, AI agents, and MCP integrations for B2B SaaS teams. Before this, I spent twelve years operating e-commerce, marketing, and ops across India, Dubai, and US-remote engagements. The shorthand: I've been the person responsible for systems that actually had to make money, not just demo well.
Numbers I've put behind real work.
Not vanity metrics. The kind of things that show up in P&Ls and in your team's calendars.

01
AED ~100K/month e-commerce revenue, 35–40% net margins
Ran a four-platform e-commerce operation from Dubai — Shopify, Amazon.ae, Noon.com, and Carrefour Marketplace — covering catalog, inventory, order fulfillment, and customer engagement. Net margins held in the high-30s even as the marketplace tax burden moved.

30% online-sales increase via integrated catalog + comms
Integrated Freshchat and WhatsApp with internal systems to streamline vendor and operations coordination. Owned product catalog and sales enablement alongside the dev team. The needle moved 30% on online sales over the engagement.

1.5× sales growth on a brand-new line launch
Launched the "Dresses on Rent" e-commerce line from cold-start through digital marketing, oversaw daily store operations, and ran the Java-based ERP that kept billing accurate. The line delivered 1.5× the previous period's sales.

10+ hours/week saved per client with automation scripts
Wrote product-upload and inventory-sync scripts (Google Sheets + Shopify + Amazon APIs) that absorbed the boring chunk of e-commerce ops. The time-saving was repeatable across stores — same shape, different SKUs.

05
AI-driven first-line CS that gracefully escalated
Built ChatGPT + Gemini chatbots on Crisp and Zopim with confidence-gated handoff — the bot answered when it was sure, handed to humans when it wasn't. Response speed up, CS load down, escalation quality maintained.

06
No-code API portal that put non-developers in charge
Built a Bubble.io self-serve portal that let clients configure their own API automations — linking Bitrix24 to comms apps without writing code. Deployment cycles got dramatically shorter; engineering wasn't the bottleneck anymore.
MyOperator (VoiceTree Technologies) · 2024–2026
Six companies, three countries, one consistent role: the operator.
Every place taught me a different layer — e-commerce, marketing, integrations, AI. NextFlow Builder is the place I get to combine all of them.

2015 — 2016 shipped E-commerce & Operations Manager
Aryan Creations · New Delhi, India
Launched the "Dresses on Rent" e-commerce line from zero — digital marketing, daily store operations, and a Java-based ERP for secure billing.
1.5× sales growth versus prior period
Operating principles, in plain words.
Production-first
Everything I build runs end-to-end before the invoice closes — real APIs, real data flowing through, real failure modes handled. Demos that won't survive a Tuesday aren't on the menu.
Async by default
Looms for status, docs for context, calls only when they earn their place. I run on a 9 AM EST overlap window from India; your calendar wins.
You own everything
Code, prompts, recipes, documentation — all transferred to your repo and tools at handoff. No proprietary lock-in. NDAs are fine, mutual or yours.
Honest scope
If you're not the right fit — wrong stack, wrong stage, wrong budget — I'll say so before signing. Better to lose a sale than ship the wrong thing.
Tools, not religion
n8n vs Zapier, OpenAI vs Anthropic, custom MCP vs existing — I pick based on your stack and constraints, not what I built last week. Workato if you're already there, n8n if you're not.
What I'm great at, what I'm growing in.
Real depth
- Zapier — 5+ years, muscle memory across hundreds of zaps
- n8n — 3+ years, self-hosted and cloud, the default for production builds
- JavaScript & Python automation — 8+ years of writing the bridge code when no native connector exists
- E-commerce automation — Shopify, Amazon, Noon, Carrefour — the operational pain is in my bones
- AI-LLM tool-calling — production deployments of ChatGPT and Gemini for support automation
Growing capability
- Workato — currently shipping production recipes day-to-day. If you're already on Workato and want me to wire MCP through it, I'll be honest about where I'm at and we'll scope accordingly.
- Custom MCP-server builds — the default offer is setting up existing MCP servers (Zoho, GitHub, etc.) or MCP-native platforms. Custom-from-scratch is an add-on we'd discuss explicitly.
- Cloudflare Workers AI — actively building, this site itself runs on the Cloudflare Workers / Pages stack.
