I build stores that sell, and tools people keep.

Full-stack eCommerce developer with 8+ years on Shopify, Magento 2 and PHP. I ship client stores by day as a Shopify Partner, and in between I build small desktop tools that fix the things that slow me down.

About

Hi, I'm Sudhakar. One man, a lot of shipping.

I build consumer-facing websites, and most of them are online stores that have to hold up under real traffic, real catalogues and real payment volume.

Since 2016 I've worked for agencies and product teams, from Mequals and Altius to Heptagon, and now Native Brand Technologies. My longest-running client is Tangelos, a luxury bedding brand with Shopify stores in the UK, Australia and New Zealand.

Day to day that means custom modules, Shopify apps, payment gateways, Meta tracking and AWS servers. When a small thing slows down my day, I write a tool for it. Some of those tools turned into the products below.

Products

Real tools I've shipped.

Free desktop apps for Windows, macOS and Ubuntu. No accounts, and nothing leaves your computer.

ClipKeeper

Clipboard manager

Keeps a history of everything you copy so you can bring any clip back in about two seconds. Search as you type, pin what you reuse, and skip anything a password manager marks as secret.

Hangly

Desktop charms

Digital charms that swing on your desktop with real rope physics: weight, momentum and a little bounce when you nudge them. Over 100 charms, nine rope styles, and a studio to make your own.

Pendu

Charms for Ubuntu

A charm on a rope at the top of your Ubuntu desktop. Drag it, fling it, watch it settle. Only the charm catches clicks, so it never blocks your work.

MeetWing

Meeting reminders

A little jet flies across your screen before every meeting, towing a card that says what's starting. It works with Google, Outlook and iCloud calendars or plain reminders, and has one-key Join for Zoom, Meet and Teams.
