NO SUS 1.1.8: links that open, and sharing across screens.
The current Android release improves link opening, accessible web controls and photo recovery. The 1.1 series follows the earlier 1.7 and 1.8 builds after a version-number reset.

SURANG-SUTRA: checking the cage and puck exit before fabrication.
The Stage 2 repository now includes a parametric FreeCAD assembly, STEP/STL exports, clearance checks and cage-impact analysis.
SURANG-SUTRA design files and a refreshed robotics resume.
My Embedded Robotics resume now covers SURANG-SUTRA, a mine-rescue scout and relay-puck design shortlisted for Stage 2 of the Vishwakarma Awards 2026-27.
01 / Selected work
A closer look at what I build.
Real interfaces. Working prototypes.
The thinking behind each one.
01Product / software
NO SUS
Private sharing, with an expiry date.
An Android and web app for sharing documents, sending burn notes, and opening selected Drive files on a borrowed computer.
Inside the build
The problem
Sharing a file often means losing track of access. I wanted the sender to keep useful controls after sending it.
Live website · Android 1.1.8 + web
What I built
- Built a Flutter client and Supabase backend for document sharing, viewer-entered email watermarks, view limits, expiry, and access logs.
- Added browser-encrypted burn notes and files, plus a phone-approved flow for opening selected Drive files on another computer.
- Direct-link keys stay in the URL fragment; short pairing codes temporarily hold the key server-side. Watermarks provide an attribution clue, not verified identity.
- Released Android 1.1.8 after restarting version numbering. The release documents web fallbacks for Android links, accessible link-page controls, camera-photo recovery and crash-report controls.
- The current release series adds username.nosus.foo addresses, phone-approved sessions on another screen and optional one-use, ten-minute sharing codes. For codes the server temporarily holds the key; direct links remain the default. The server migration requires signing in again, and old links, groups and accounts do not carry over.

02Hardware / software
Niva
From an insole to an understandable gait signal.
An ESP32 smart-insole prototype with a web dashboard, mobile app, and biomechanics rules that can be inspected.
Inside the build
The problem
Sensor readings are only useful when you can explain how they become gait measurements.
Hardware + software prototype
What I built
- Acquired pressure, piezoelectric, and MPU6050 telemetry using ESP32 firmware.
- Implemented USB Serial and Wi-Fi WebSocket transport, a React dashboard, and a Flutter mobile app.
- Calculated gait phase, cadence, center of pressure, and stability using explicit rules. The preview shows a disconnected prototype, not a clinical validation.
- Showcased the prototype at Automation Expo in July 2026 with the project team.

03Hardware / software
SURANG-SUTRA
A roll-and-fly scout and relay pucks for mine rescue.
A mine-rescue design: an X-quad inside a rotating geodesic cage, plus a cassette of five communication-only relay pucks. Shortlisted for Stage 2 of the Vishwakarma Awards 2026-27.
Inside the build
The problem
In a dark, GPS-denied mine gallery the operator link has to survive each bend, and the floor can hold debris or water.
Design stage · no hardware built · Vishwakarma Awards 2026-27 Stage 2 shortlist
What I built
- SURANG is a collision-tolerant scout: an X-quad inside a single-axis rotating geodesic cage that rolls on a sound floor and flies over debris or water.
- SUTRA is a cassette of five communication-only relay pucks. The scout drops one before each bend to keep the operator link alive in dark, GPS-denied galleries.
- Published KiCad schematics for the relay puck and avionics interconnect (ERC clean), with a pin map, power budget and costed BOM.
- Added a parametric FreeCAD assembly, STEP/STL exports, clearance and puck-exit checks, and cage-impact analysis with a mesh-convergence study. The analysis motivated thicker cage struts, a wider axle, softer hub caps and an offset puck cassette.
- Design stage only: no hardware has been built or measured, and every figure is a target or a calculation. The design is not intrinsically safe and not DGMS, ATEX or IECEx certified.
- AI tools assisted with the CAD scripting, the analysis code and the renders. The design decisions, review and fabrication are the team's.

04Product / software
Aurigen
Blocks to firmware. All in the browser.
A visual programming workspace for ESP32 and Arduino: assemble blocks, inspect C++, simulate, then flash a real board.
Inside the build
The problem
Getting started with a microcontroller often means installing a toolchain before writing anything.
Live browser workspace
What I built
- Connected Blockly to generated C++, a queued cloud compiler, and browser-based USB flashing.
- Built an instant block interpreter and an AVR firmware simulation path.
- Implemented ESP32 and Arduino flashing paths. Physical flashing requires compatible browser, hardware, and backend availability.
- Co-founded Aurigen and helped run a hands-on ESP32 walking-robot workshop at TSEC in August 2026.

05Product / software
M-Indicator 2.0
A new front door for a familiar commute.
A responsive website concept for M-Indicator, bringing transit features, city coverage, and product information into one browsing experience.
Inside the build
The problem
Transit information spans routes, fares, cities, and safety. The website needed a clear way to explore that breadth.
Independent website concept · M-Indicator belongs to Mobond
What I built
- Built a responsive multi-page frontend with an interactive Leaflet city map.
- Organized transit features, news, product updates, and contact pages with shared navigation.
- The recording shows my website work; the original transit app, brand, and adoption figures belong to Mobond.
HTML5 / CSS3 / JavaScript / Leaflet.js
06Product / software
crypt.ml
A risk score with a reasoning trail.
A multi-agent AML prototype connecting transaction rules, ML scoring, graph analysis, and an operations dashboard.
Inside the build
The problem
A flag is more useful when an analyst can see which signals produced it.
Live dashboard demo
What I built
- Designed five cooperating agents around an asynchronous event bus.
- Used XGBoost and SHAP contributions for inspectable risk scoring, alongside graph-based pattern detection.
- Built an analyst dashboard and SAR drafting flow. Displayed statistics are demo content, not independently measured production results.
Python / FastAPI / React / XGBoost / SHAP / NetworkX / Docker
07Cryptography / experiment
NO SUS Canary
Different words. A traceable copy.
A note-sharing experiment that gives each reader a differently worded copy and records seal/open receipts on Solana devnet; it began as a Monad testnet hackathon project.
Inside the build
The problem
A leaked text copy can lose file metadata. Can the wording itself help identify its source?
Testnet experiment
What I built
- Won second place at Monad Blitz Mumbai V4 (19 September 2026).
- The original Monad testnet version won the September award; the current public version uses Solana devnet memo receipts for seals and opens.
- Built a paste-and-check flow for comparing leaked text with distributed variants.
- Leak matching runs on the sender’s device. A receipt records what the relayer submitted; it does not verify a reader’s identity or prove who shared a copy. Rewriting or blending copies can defeat matching.

Curious about how
things actually work.
I’m studying Electronics & Computer Engineering at TSEC in Mumbai. My work moves between embedded hardware, robotics, and software people can use.
I care about the path from a sensor to an interface, and from a system’s decision to an explanation. That’s what connects an ESP32 insole, a browser programming tool, and a document-sharing app. I founded NO SUS to build privacy-focused document-sharing tools, and co-founded Aurigen to make robotics more approachable through tools and hands-on workshops.
