Nebula Buds Pro Ctl

Nebula Buds Pro Ctl

Reverse-engineered OnePlus Buds Pro 3 and built a desktop control app from scratch. No official APIs, no tutorials.

Reverse Engineering:

•Captured and analyzed raw Bluetooth traffic from Android logs

•Decoded RFCOMM UIH frames and custom binary packet structure (0xAA prefix)

•Rebuilt handshake flow: HELLO → SUBSCRIBE → REGISTER → NOTIFY → GESTURE_REGISTER

•Prototyped on Linux with BlueZ, ported working logic to Windows Bluetooth stack

Desktop App Features:

•Direct RFCOMM connection with dynamic device selection

•Real-time gesture detection (double/triple tap, long press) and remapping

•ANC mode control (on / transparency / off)

•Battery monitoring for both earbuds and case

•Live RX/TX packet logging and raw command execution

Stack:

•Go backend with raw RFCOMM sockets and custom binary protocol

•Wails v2 + React + TypeScript for glassmorphism UI

•GitHub Actions CI with prebuilt .exe releases

•Event-driven architecture bridging React UI through Wails to Go service layer

Warp-Transducer (ESPnet)

Warp-Transducer (ESPnet)

Maintainer of the warp-transducer fork now used by ESPnet, with cross-platform CUDA support and FastEmit integration. PR merged into main ESPnet repo.

Cross-Platform Support:

•Made warp-transducer work on Native Windows (no longer Linux-only)

•Validated on WSL2, Ubuntu, CentOS, and ARM64 distributions

•Tested on H100 / H200 GPU servers and CI containers

•Identical RNN-T loss values vs the previous fork (numerical equivalence)

CUDA & Build System:

•Modern CMake (≥3.18) and legacy toolchain compatibility

•Dynamic CUDA architecture detection based on toolkit version

•Comprehensive CUDA path validation and OpenMP handling

•Function-based bash install script with graceful error handling

FastEmit & ESPnet Integration:

•Integrated FastEmit for improved latency regularization in RNN-T

•Replaced ESPnet's previous warp-transducer dependency (b-flo fork)

•PR #6187 merged August 2025, approved by maintainers including b-flo

•Active maintainer of ongoing fixes and improvements

iFly

iFly

Safety boundaries and verbosity control for Claude Code. "I'm Feeling Lucky."

Safety Enforcement:

•Blocks destructive operations (force pushes, recursive deletions, sensitive file access)

•Three configurable guard levels: off, project (repo-scoped), strict (adds network blocking)

•PreToolUse hook for advisory checks within Claude's tool flow

•Prevents risky shell commands and dangerous file operations

Verbosity Control:

•Five configurable output modes from "silent" to "caveman"

•Adjustable communication style without token overhead

•Companion CLI for easy configuration management

Configuration:

•Multi-layer configuration: defaults.yaml, global ~/.config/ifly/config.yaml, per-project .ifly.yaml

•Environment variable overrides for flexibility

•Plugin and CLI installation options

•Built in Go for performance and portability

Vagyojaka: ASR Post Editor

Vagyojaka: ASR Post Editor

Interactive ASR post-editor to refine transcripts generated by advanced AI models for Indian native languages.

Performance & Engineering:

•Spearheaded ASR transcript processing optimization, raising system performance by 20%

•Boosted data loading speed 10x with a custom C++ algorithm

•Architected and implemented Git version control integration (libgit2) inside a custom C++ Qt GUI

•Enhanced audio/video processing with FFMPEG and FFTW3 for waveform visualization

•Switches audio devices dynamically without restarting the editor

Workflow & UX:

•Collaborated with the BharatGen team to streamline annotation workflow, boosting efficiency by 50%

•Improved user satisfaction by 30% through feature enhancements based on user feedback

•TTS-Annotation implementation with lazy loading

•Resizable columns and ASR validation crash fixes

•Customizable fonts, configurable speaker/timestamp delimiters

•Marathi and Telugu dictionary support, reduced unwanted logging

Cross-Platform & Reliability:

•Led cross-platform compatibility for Windows, Linux, and macOS (including Apple Silicon)

•CMakeLists fixes for Unix builds (Mac and Linux)

•Doxygen-generated documentation across the codebase

•Log file auto-trimming to 10k lines and memory leak fixes

Used by BharatGen, IIT Bombay, and partner startups (vendors).
