A closer look at what I build.

Real interfaces. Working prototypes.
The thinking behind each one.

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.

Project story ↗Visit nosus.fooOpen web appAndroid releases
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 + 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.

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.

Project story ↗Source
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.

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.

Project story ↗Visit aurigen-apps.vercel.appSource
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.

Recorded live website · all seven pages

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.

Project story ↗Visit shubham-sahu.meSource
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.

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.

Project story ↗Visit crypt-ml-rho.vercel.appSource
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.

NO SUS Canary

Different words. A traceable copy.

A Monad testnet experiment that gives each reader a differently worded note, then checks leaked text against those variants.

Project story ↗Visit shubham-sahu.meSource
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

  • Issued reader-specific linguistic variants and recorded opens on Monad testnet.
  • Built a paste-and-check flow for comparing leaked text with distributed variants.
  • The experiment traces a distributed copy through wording; it does not establish the identity of the person who shared it.

02 / About

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 also co-founded Aurigen to make robotics more approachable through tools and hands-on workshops.
