The Manifesto

The law governs us all, yet its language locks most people out. I build production-grade systems to break those locks.

Core Capabilities

Save 4+ Hours Per Case

Upload judgment PDFs — the system auto-extracts ratio decidendi, obiter dicta, key statutory sections, and the court's final holding in under 2 minutes.

Zero-Hallucination Citations

Every case reference retrieved from verified corpus before generation. If a precedent doesn't exist in the database, the system says so. Explicitly.

Court-Ready Drafts

Generate writ petitions, bail applications, affidavits pre-filled with correct statutory citations and jurisdictional formatting — ready for filing.

AI Court Simulator

Simulate oral argument sessions against an AI judge trained on Indian courtroom procedure.

Statutory RAG

Hybrid vector + keyword search across 14,900+ SC judgments. Zero hallucination at retrieval.

Criminal Law Bridge

Section-by-section mapping: IPC to BNS, CrPC to BNSS, IEA to BSA with annotated variations.

Drafting Studio

Generates jurisdiction-specific documents with verified statutory sections and court templates.

Linux Kernel BLE Input Proxy

Linux KernelevdevBlueZ D-BusGATT 0x1812Python

A high-performance daemon that turns any Linux machine into a universal Bluetooth LE HID proxy. Hooks into the Linux evdev subsystem for zero-latency input routing to iPads, macOS, and Windows — no client agents.

Kernel & BLE Architecture

Zero Latency evdev

Captures raw hardware keystrokes directly from Linux evdev subsystem with sub-millisecond dispatch.

Agentless Compatibility

Target devices require zero software. Broadcasts as standard Bluetooth LE GATT peripheral.

Native Wayland Support

Bypasses display servers — operates on Wayland, X11, and headless Linux server TTYs.

Ultra Battery Efficient

Event-driven architecture idles at less than 1MB RAM and 0% CPU during non-active periods.

Core Architecture

Dynamic Dataset QC

Python ingestion pipeline validating question data against strict schema rules — flagging mismatches and duplicates.

RAG Explanations

Generates contextual explanations by retrieving the relevant formula, theorem, or legal provision per question.

Vision OMR Scanner

OpenCV pipeline processes smartphone photos of OMR sheets — detecting grids, identifying bubbles, grading instantly.

Algorithmic Assembly

Constructs balanced mock tests against defined spec: exam type, difficulty ratio, subject distribution.

The Architect
Approach01

Source Code Over Theory

I learn by reading real production codebases on GitHub, studying technical whitepapers from research labs, and reverse-engineering how mature systems actually work — not from passive video courses or textbook exercises.

Execution02

End-to-End Ownership

I design, code, test, and deploy complete systems independently — from initial system design and database schema to the final pixel of the interface. No handoffs. No outsourcing. Total ownership of the outcome.

Mindset03

Relentless Iteration

Every difficult problem gets solved the same way: break it down, build the smallest failing case, fix it, and repeat. Late-night debugging sessions aren't a cost — they're how I actually understand how a system behaves under pressure.
