The work happens in a dark room with one wall lit magenta. Everything that keeps it worth doing happens somewhere with no signal.
Autonomous Systems Developer/Robotics, agentic workflows, self-hosted AI
I build things that run on their own.
I build things that run on their own.
I build systems that keep working when nobody is watching: robots that take instructions in plain language, and AI that runs on hardware I own.
I would rather understand a whole stack than trust a black box, so almost everything here is self hosted: local models, my own vector store, my own queue. The interesting problems start once a thing has to keep running on its own.
Machines and pipelines that carry a task from start to finish without a person holding their hand at every step.
LLM driven orchestration with state validation, human approval where it matters, and a hard stop where it does not.
Local models, custom quantisation and vector search running on hardware I control rather than someone else's API.
Cobots, mobile robots and factory workflows connected to the software layer that actually decides what happens next.
KhojAI
Reads roughly fifty thousand documents a day and hands back the three hundred that matter. Regex prefilters, GLiNER entity recognition and embedding deduplication feed a local Qwen3 4B under Ollama. A Ghost Signal Engine flags evidence that quietly disappears. Custom quantisation keeps the whole system inside 4.5 GB of memory.
Voice-Controlled Cobot
Natural language control for a Techman TM5M-700 collaborative arm and an autonomous mobile robot at IIT Delhi. An LLM intent parser turns plain speech into motion commands, each one validated against live robot state before anything is allowed to move.
RFQ to Purchase Order
Production n8n pipelines that carry a request for quotation through to a purchase order, pausing for human approval over WhatsApp at exactly the points where a human should decide. Factory maintenance flows on the same backbone raise their own tickets.
ElectroSentry
An ESP32 rig that watches metal corrode. pH and TDS sensing, a Wi-Fi dashboard, and cathodic protection driven straight from the readings. Third place at the college exhibition.
Grammar Score Engine
Scores grammatical correctness in spoken English with no human in the loop. Speech recognition on the front, supervised regression over transcript features behind it.

The room
Comms rail
Everything that interrupts, kept off the main screen.
The machine
Editor, containers, and whatever model is running locally.
The reference
Robot state on one side, running build on the other.
Where the hours go
Most of this was built between midnight and four.
I got into this through hardware, then found out the interesting part was the software deciding what the hardware should do next. Now most of my time goes into the layer in between.
Day to day that is Python and ROS near the machines, Next.js where a human has to look at something, and a local model doing the reasoning in the middle. Almost none of it calls out to an API I do not own.
Tools in rotation
Started building in public. Learned by taking systems apart rather than reading about them.
ElectroSentry: ESP32 corrosion monitoring with pH and TDS sensing, a dashboard and cathodic protection. Third at the college exhibition.
Grammar Score Engine. Speech recognition feeding supervised regression to grade spoken English without a marker.
IITD-AIA Foundation for Smart Manufacturing, through August 2026. Built natural language control for a Techman TM5M-700 cobot and an autonomous mobile robot.
KhojAI. A self-hosted intelligence platform that reads fifty thousand documents a day so a person only has to read three hundred.
