On-device pose estimation with automatic rep counting and live visual feedback — zero cloud, zero manual input.

Built on Google's ML Kit pose model, running entirely on-device. The system tracks joint angles frame-by-frame, infers rep boundaries from motion state transitions, and gives audio-visual feedback in real time. No server roundtrip. No latency. No privacy leakage.

Hardware + AI test system: teachers upload PDFs, AI generates the quiz, ESP32 administers it, AI evaluates and returns personalized feedback.

A full-loop system. PDF upload → NotebookLLM parses and generates structured JSON quiz → POST to ESP32 → adaptive TestState engine runs branching question trees on hardware → student answers via keypad, touch sensor, or voice → responses queued to Next.js backend → AI returns targeted feedback on weak points. Hardware interface: OLED, TM1637 7-seg timer, 4×4 matrix keypad, touch-to-record audio, active buzzer. Audio captured as WebM/Opus, encoded to MP3 (44100Hz mono 128kbps) before backend sync.

Fault-tolerant real-time multiplayer with live room sync and authoritative server-side state.

The state lives on the server. Clients are thin. Room synchronization handles late joins, disconnects, and reconnects without desync. Built to stay consistent under network noise — not just under ideal conditions.

Portable RF and wireless monitoring node running entirely on an Android device via Termux — no dedicated hardware needed.

Real-time radar visualization, WiFi scanning, device presence detection, RF density graphing, and motion detection — all in a dark cyber-console dashboard served locally from the phone. Self-contained. Zero cloud. Useful in the field.

YouTube viewers type in chat → their named entity spawns and fights inside a procedurally generated arena.

The game reads live messages, spawns controlled entities per username, and handles concurrent inputs from an audience in real time. An experiment in turning passive viewership into active participation.

Full private music server running on an Android phone — Subsonic-compatible, zero tracking, full library control.

Ubuntu userspace via proot inside Termux. Navidrome handles indexing and the Subsonic API. Ultrasonic on Android as the client. No subscription, no third-party servers, no data leaving the device.

Production APIs on RapidAPI — privacy-preserving, deterministic, no ML black boxes.

• Password Risk Detection — breach exposure scoring and guessability analysis, privacy-preserving
• Email Risk & Disposable Domain — MX validation, typo detection, subdomain and disposable checks
• CSV Data Cleaning & Normalization — schema-safe, deterministic pipeline

Sarbanash — 2D pixel-art survival horror. Classic Pokémon-style exploration meets atmospheric dread. Complete story, event-driven gameplay, state machines throughout.

Kisor — A choice-driven psychological mystery. Best experienced blind. You're guiding terminally ill students through their final year. Text-based, branching, heavy.
