I make slow sites fast.
Under your brand.
White-label available Agencies hand me their clients' slow Shopify, WordPress and React sites. I hand back green Core Web Vitals, delivered under your name, proven with before/after numbers.
Every score on this page is live. Audit it yourself, then send me a site to make fast. You only pay when the numbers pass.

You don't trust proof. You trust results.
No portfolio to vet, no upfront risk. Send a client's slow site, I make it fast where you can test it, and you pay only when the numbers pass.
Send a slow site
Email a client's URL and the target. I run Lighthouse and send back an honest read within 24 hours, including "not worth fixing" if that's the truth.
I fix it on a staging copy
The work happens on a copy you control, so nothing touches production. You watch the numbers move, milestone by milestone.
Pay only when it passes
You verify green Core Web Vitals yourself. Only then do you pay and I hand off the branch to merge. Miss the target, owe nothing.
The only site I ask you to trust is this one. arnabsamanta.com scores 100 across the board. Audit it above.
You sell it. I build it.
Your name on everything.
Your agency offers speed optimization. I deliver it in the background. Your client sees your brand, your invoice, your win.
Your brand, my keyboard
Reports, video walkthroughs, commits: unbranded, or carrying your logo. Your client never hears my name. If I'm ever put in front of them, I'm your performance engineer.
Your margin, protected
Flat wholesale rates, quoted before work starts. You set the retail price and keep the spread, and most partners roughly double it. My rates never appear anywhere your client can see.
Your exit, always open
A one-page agreement per project. 50% to start, 50% on delivery. No exclusivity, no retainer, no lock-in. If the work isn't excellent, you never have to come back.
Built for the moment a client says "the site feels slow." Failing Core Web Vitals, mobile bounce climbing, ad ROAS bleeding, and speed isn't on your services page yet.
Brief me tonight. Wake up to progress.
Async by default: written briefs in, recorded walkthroughs out. You get artifacts you can forward, not meetings you have to summarize.
Brief me
Send the URL and the goal, in writing. No discovery-call theater. You get an honest read within 24 hours, including "not worth fixing" if that's the truth.
Teardown & quote
A recorded teardown of what's slow and why, plus a fixed wholesale quote. No hourly meter, no scope surprises. You forward the teardown to your client as your own.
The work
I'm in the codebase on a branch. My working day starts as yours ends, so brief me tonight and wake up to progress. Before/after snapshots at every milestone.
Handoff, your way
Fixes live, plus a faceless video walkthrough and a before/after report, editable and unbranded. Your logo goes on top. Your client thanks you.
Fair questions, straight answers.
Do you actually work white-label?
Yes, it's the default, not an add-on. Every deliverable ships unbranded or carrying your logo: audit reports, video walkthroughs, before/after decks, commit history. You sell speed optimization under your agency's name; I deliver it in the background. That arrangement is written into the one-page agreement before any work starts.
Will our client ever know you exist?
Not unless you want them to. Communication runs through you by default. If you ever need me client-facing, say a technical question on their call or a Slack thread, I show up as your performance engineer, under your brand. Agreed in writing up front, so it's never awkward in the moment.
No testimonials. How do we know you're good?
Fair question, I'd ask it too. My proof is live instead of quoted: four production sites I designed, built and tuned myself, all scoring 100 across every Lighthouse category. Run PageSpeed Insights on any of them right now, mid-email. Then send me your hardest slow site and judge the teardown I return.
Where are you based, and does it matter?
India, UTC+5:30. For you that's a feature: brief me at your end of day and the work happens while you sleep. Invoices are in USD via Wise or Payoneer, clean and standard with no friction. Agencies subcontract globally every day; the only thing that should matter is whether the numbers move.
How do you communicate?
Async-first, and deliberately so. Written briefs, email or Slack, and recorded video walkthroughs for anything visual, so you get artifacts you can forward, not meetings you have to summarize. Happy to do an intro call when we start so you know there's a real engineer on the other end; after that, async keeps both our calendars clean.
What stacks do you work on?
Shopify and WordPress storefronts, React, Next.js, Vue, Nuxt, Astro, and static builds. If it renders in a browser, I can profile it and make it faster. I work on a branch in your (or your client's) repo and hand off clean diffs, so you control the merge and deploy.
What are the payment and contract terms?
Per-project, always. 50% to start, 50% on delivery. A one-page agreement covers scope, turnaround, white-label terms and rates. No exclusivity, no retainer, no lock-in. Wholesale rate card is in the partnership doc; ask and I'll send it.
What if the numbers don't improve?
We agree the target (LCP, CWV pass, load time) at kickoff, against the codebase as it stands that day. If I miss it, I keep working at no extra charge for one additional delivery window. Regressions from third-party scripts or content added after delivery are carved out in writing, so we're both protected.
One URL. One honest read.
