📌 Pinned Showcase

🎙️ sarvam-mobile

Official Client SDK Monorepo for Sarvam AI
Indic-first Speech (STT/TTS), Translation & Dubbing SDKs for Swift 6, Kotlin, Flutter, and React Native powered by a shared <600 KB Rust Core Engine (JNI, C-FFI, dart:ffi, WASM) for 16 kHz PCM DSP resampling, single-flight token coalescing, and SSE/WS streaming.

⚡ go-template

Production Clean-Architecture Go Microservice
Enterprise Go 1.24 microservice blueprint implementing Uncle Bob's Clean Architecture & DDD. Features RBAC JWT auth, PostgreSQL with Prisma Client Go, sharded rate limiting, OpenAPI/Swagger generation, race-detector test suites, and Kubernetes/Docker manifests.

🥭 mango

"Your Mind, Architected" — Mindfulness & Affirmations
Tactile Flutter application featuring real-time hardware accelerometer parallax backgrounds (sensors_plus), a 4-stage evolving mascot streak engine, multi-category Mix Mode, custom theme studio, and native iOS/Android home screen widgets.

✨ aura

Modern Open-Source Dating Platform
Feature-first Clean Architecture dating app built with Flutter & Supabase. Engineers 60 FPS card-swipe physics, passwordless OTP & Apple/Google social auth, real-time Postgres matching & chat streams, profile completion rings, and tiered freemium paywalls.

🧩 sudoku-solver

Augmented Reality Computer Vision Sudoku Solver
End-to-end computer vision pipeline that extracts puzzle grids via Hough Space transforms, classifies digits with a Deep CNN, solves boards via algorithmic backtracking, and projects the solution onto live video in real-time AR.

🧠 emotion-detection

Real-Time Facial Emotion Recognition Engine
4-layer Convolutional Neural Network trained on FER-2013 across 7 emotional states, paired with OpenCV Haar cascade face detection for low-latency live webcam inference.
