Selected work
A few of the products I've built, and the thinking behind them.
All work
Deepen Refinery
Physical AI data marketplace
Deepen's marketplace where AI teams buy physical AI datasets to train their models. I built its entire frontend, from the first commit to launch.
Labeling Agent
Self-reviewing image labeling agent
I built an AI agent pipeline that labels camera data and reviews its own work. On production datasets, its accuracy came close to human-labeled quality, beating the best open-source models.
Gigapixel annotation
100,000-pixel images that pan like a map
I built an image processing pipeline that lets the labeling editor handle 100,000-pixel images, far beyond what a browser can load, with every label type still working.
Webpack 5 to Rspack
Dev startup, from a minute to under a second
I moved a huge frontend from Webpack to Rspack. Dev startup under a second, cloud builds roughly 85% cheaper.
PII anonymization
Face and license plate anonymization
I built a PII anonymization pipeline that blurs faces and license plates in camera data. It holds up even in motion blur, aerial shots and low light.
Learning Hub
Labeling training platform
I built a training platform where people learn AI data labeling, with instant visual guidance and scoring engines that assess the quality of their work.
Open source
Four packages I maintain in the open, covering local coding-session management, color, accessible focus behavior and JavaScript utilities.
All open sourceA local session manager for Codex and Claude Code. Review, understand, and clean up sessions safely, without anything leaving the machine.

- Type coverage
npm install deep-equal-js
About
I like the part of the job where the answer isn't written down yet.
I'm Mallik Cheripally, a Staff Software Engineer at Deepen AI, based in Hyderabad. For more than a decade I've built complex web products, product platforms, and developer tools, from shaping the first version to keeping mature systems clear, fast, and dependable as their data, teams, and requirements grow.
Often the starting point is an idea, not a specification, so someone has to decide what the product is before anyone can build it. I do both parts. The hardest call is usually what not to build yet, and the states that matter most are the difficult ones: the empty ones, the failing ones, the ones with more data than expected. I build it myself, so if a decision is wrong I find out while it's still cheap to change, and I stay on it while real data and usage find the constraints that weren't visible at the start.
I joined Deepen in 2018 as a senior frontend engineer, took more than five of its products from an empty repository to production, annotation and calibration among them, and was promoted to Staff in 2022. These days I own products end to end, from AI and data pipelines to the interface, guide the engineers I work with, and set the practices we build by. Before Deepen, I did product engineering at Knex and Java applications at TCS.
