What I'm Focused On

Five disciplines. One practice.

Across digital marketing, growth systems, automation, product, and revenue strategy, I work the seams — the places where most companies have a department but no system. That's where the leverage lives.

Over 16 years, the work has spanned B2B SaaS, e-commerce, and service businesses. The operating principle stays the same: find the inefficiency, build the tool, ship it.

This week: wiring a Klaviyo → n8n → GA4 attribution loop.

where n8n happens

Based in Kolkata, operating across India and internationally. The journey started at the intersection of technical and digital marketing — building things, then figuring out how to grow them.

Over time, those two instincts merged into one focus: building tools that scale. Not campaigns. Not decks. Production systems with real users.

Currently directing digital marketing & development operations at Techievolve Global IT Solutions Pvt Ltd, where the work spans team building, product development, and multi-channel revenue strategy.

06 / Common Questions

Things people usually ask

Are the free tools actually free?
Yes. No signup, no email gate, no upsell. I built them because I needed them, and I figured if I needed them, someone else probably does too. They'll stay free.
What stack do these tools run on?
Mostly PHP + JavaScript for the in-browser tools, n8n for workflow automation, OpenAI for the AI pieces, and Cloudflare Workers for edge stuff. Boring, durable, easy to debug.
Can I request a new tool or feature?
Yes — and please do. I keep a public-ish backlog of ideas, and if something gets enough votes (or solves a problem I'm also having), I'll build it. Drop a note via the contact form.
Why are some tools "on request"?
Those are systems I built for clients under NDA. I can't open-source the code, but I'm happy to walk through what they do, the architecture, and where the gotchas were. Useful if you're building something similar.
How often do you ship new tools?
Roughly one every 4–6 weeks. Subscribe to the newsletter and you'll hear about each one the day it goes live. No spam between launches.
Found a bug — what do I do?
Use the contact form with topic "Found a bug (sorry)", paste the URL + what broke, and I'll usually fix it within a day. Screenshots help. So does a snarky tone.
Can you build a custom tool for my team?
Sometimes — depends on bandwidth. If it's interesting and well-scoped, drop me a line via the form. I prefer projects that produce something I can reuse for the next client (with their permission).
How quickly do you reply?
Form submissions and emails: within a day, usually a few hours. Live chat is fastest for short questions. I'm in Kolkata (IST, UTC+5:30) and work standard hours.
