I learn by building.
I’m drawn to ideas that sound interesting but might not quite work yet. Building something is how I find out.
Pranshul Chandhok / 2600th
I’m VP Product & Technology, Interior Company at Square Yards.
I work across AI and real-time 3D, and stay hands-on with the software we build. I’m based in Gurugram.
How I got here.
- Game development
Starting with games.
I started as a game programmer. Working on mobile games taught me to care about how software feels: the controls, the feedback, and whether it runs well on the device someone actually owns. Later, at Merkur, I worked on cross-platform Unity development.
- Co-founder and CTO
Building GreyKernel.
I co-founded GreyKernel in 2015 and led its technology work for six years. We built immersive learning systems and games, helped set up JPMorgan Chase’s Mumbai immersive lab, and developed training software for Anglian Water. I also learned how much of a founder’s work happens outside the code.
- Product and technology
Working on design software.
At HomeLane, I worked on SpaceCraft Pro as principal software architect. Today I lead product and technology work on Blocks with our product, engineering and design teams. Designesto focuses on visual exploration and revision, with deeper costing and execution integration still on the roadmap. I also built the initial PropVR AI MVP that PropVR’s team developed into Craft. Outside work, I keep experimenting with browser graphics, games and local AI.
What I mean by building.
My work moves between product direction, technical architecture, prototypes and implementation. Sometimes I’m building the first version; sometimes I’m helping a team decide how the system should work and carry it into production. Each Work page describes my role and the people who took it forward.
My independent projects in the Lab are where I can try an idea, inspect the result and share the code.
2600th is an old handle from my college-era interest in hacker and phreaking culture. It stuck.
Tools in use.
- Browser graphics
- TypeScript, Three.js and WebGPU in Web Ocean 3D. Rapier supports physics in Kinema.
- Applied AI
- OpenAI and Gemini for floorplan interpretation, with ComfyUI for repeatable image and video experiments.
- Product prototypes
- Next.js, Tailwind CSS, AI SDK and fal.ai formed part of the initial PropVR AI MVP I built for the team to extend.
Humanoid Robot Control System
At GreyKernel, I co-invented a system for controlling a humanoid robot using tracked human movement. Indian Patent No. 395331 was filed on 14 February 2019 and granted on 25 April 2022.
My co-inventors are Abhishek Gupta, Devesh Kumar Singh, and Tej Pratap Singh. GreyKernel Technologies India Pvt Ltd holds the patent.
How I work.
- Try the idea.
I often build a small prototype to answer a question. It gives the team something concrete to discuss. - Stay close to implementation.
I test tools and read the code before recommending them. Their limits matter as much as their capabilities. - Pay attention when it breaks.
Slow responses, memory limits, and confusing controls tell me where more work is needed. - Use AI where it helps.
Sometimes a deterministic rule or a database query is the better choice. Some decisions still need a person.
