Clients
In their words.
We wanted our first collection to feel like a lookbook, not a template store. Kartik built a custom Shopify theme around it and handled the details we hadn’t thought of. The launch went smoothly.
Founder, KHOYSee the site Kartik redesigned our store so browsing and checkout feel effortless on a phone, which is where most of our customers shop. Quick to respond and clear about every change.
Founder, Schon ZapatoSee the site Around 200 players, a live auction on the big screen, and scores updating on everyone’s phones, all on one platform Kartik built for us. It held up on the day, even on patchy venue Wi-Fi.
Organiser, ELEV8See the site Clean site, service pages that explain what I do, and enquiries landing straight in my inbox. Exactly what we discussed.
Founder, Marketing MachinesSee the site Kartik delivered the symposium website on time, with speakers, schedule and paper-submission details that were easy for international participants to find.
Organising committee, AI4HCE SymposiumSee the site Kartik’s team ran our website and the QR check-ins for 500+ delegates across every checkpoint, and stayed on call through the event.

Process
How a project runs.
From the first call to long after launch day.
A 15-minute call
Tell me about the business and what you need. I ask a few questions and tell you plainly what I would build.
A written proposal
Scope, timeline and one fixed price, in writing. Nothing starts until you agree to it.
Design & build
You follow along on a private preview link and your feedback goes in as the site takes shape.
Launch
Domain, hosting, email and the SEO basics set up in your name, then a final check on phones before it goes live.
Care
I stay on for fixes, updates and backups, so the site keeps working after launch day.
Pricing
One fixed price for the agreed scope, quoted after a 15-minute call and put in writing before any work starts.
Ownership
Your domain, hosting and accounts are set up in your business's name, and the code is yours. You're never locked in.
Why me
Why work with me.
One person, start to finish
The person you brief is the person who designs, builds and hosts it. Nothing gets lost in hand-offs.
Solo work, start to finish: KHOY, Schon Zapato, ELEV8 and GhostShare. I also ran the production server behind a company’s two Google Play apps.
You own everything
Your domain, hosting and accounts are set up in your business's name, and the code is yours. You're never locked in.
If you ever want someone else to look after it, everything is already in your hands.
Security is built in
Small-business sites usually get hacked through outdated software, weak logins or missing backups. I build with those in mind from day one.
$1,500 bug bounty from Meta (WhatsApp). Vulnerabilities reported to Microsoft and, through CERT-In, to the Mumbai Police.
Fast on a phone
Your customers will mostly open your site on a phone, often on mobile data. Every page is built and tested for that first.
This site scores 90+ for mobile performance on Google Lighthouse, and 100 for accessibility, best practices and SEO.
Built for the busy day
Launch day, sale day, event day: the site has to hold up when everyone shows up at once.
QR check-ins for 500+ delegates at Social Conclave, the backend of Mumbai MUN’s app for 600+ delegates, and a live player auction for a ~200-player tournament.
Clear and accountable
A fixed scope and price in writing, previews as it’s built, and one person to write to when something needs changing. I usually reply within 3 hours.
I chair a ~250-member student chapter and ran the technical teams of four college committees in 2025–26.
Know what you need? It takes about a minute to tell me.
Start a projectQuestions
Before you ask.
Something else on your mind? Write to contact@jkartik.in. Usually replies within 3 hours.
How much does a website cost?
It depends on what the site has to do: a few pages, an online store, or a custom portal are very different jobs. After a 15-minute call you get one fixed price for the agreed scope, in writing, before any work starts.
How long does it take?
The timeline is part of the written proposal, so you know it before we start. A simple business site is quicker than an online store or a custom app, and having your content ready (text, photos, logo) speeds things up the most.
Will I own the website?
Yes. Your domain, hosting and accounts are set up in your business's name, and the code is yours. If you ever want someone else to look after it, everything is already in your hands.
Can you handle the domain, hosting and business email too?
Yes. I buy or connect the domain, set up hosting with SSL, and create business email on your domain with SPF, DKIM and DMARC configured so your mail reaches the inbox. I already run the mail server that 7+ college committees use.
Will it work on phones?
Yes. Every site is built for phones first and checked on phones before launch. The phone screenshots in the work section are the actual mobile versions.
I already have a website. Can you fix or redesign it?
Yes. I can make changes, redesign it, speed it up, move it to better hosting, or check it for security problems. It starts with a look at what you have, so the advice fits your site.
How quickly will you reply?
I usually reply within 3 hours. Write to contact@jkartik.in, or use the project brief on this page and your email app does the rest.
What happens after launch?
I can stay on to look after it: updates, backups, security fixes and small changes. What that covers is agreed in writing, like the build itself.
Do you build mobile apps as well?
Yes. I build Android and iOS apps from one codebase, and have shipped two learning apps on Google Play this way.
