Native Android behavioral focus system combining productivity workflows with operating-system-level distraction enforcement.

Kotlin · Jetpack Compose · Material 3 · MVVM · Firebase · WorkManager · DataStore

• MVVM and repository separation across auth, sessions, missions, tasks, goals, analytics, discipline, streaks, and notifications.
• Foreground services keep mission/timer execution alive beyond the foreground UI.
• AccessibilityService and usage-access monitoring support app blocking during active missions.

Full-stack behavioral system with React/Vite frontend, Express APIs, Prisma domain models, PostgreSQL persistence, authentication, analytics, and extension-facing endpoints.

React · Vite · Node.js · Express · PostgreSQL · Prisma · JWT

• Prisma schema models missions, sessions, block rules, goals, streaks, achievements, reviews, consumption logs, discipline score events, and extension sync state.
• Backend routes and services are separated by domain modules rather than placed in one controller file.
• JWT authentication, bcrypt, rate limiting, password recovery, and test coverage are present in the backend repository.

Team-built Kotlin Android study system for planning, focusing, capturing notes, reviewing progress, and integrating Firebase/networked learning workflows.

Kotlin · Jetpack Compose · Material 3 · Firebase · Retrofit · OkHttp · FastAPI

• Android application uses Compose, Material 3, Navigation Compose, ViewModels, and Flow state patterns.
• Firebase Auth/Firestore and Google services configuration are present for authenticated/cloud-backed data.
• Retrofit, OkHttp, Gson, and a FastAPI video service indicate network/service integration beyond local UI screens.

NetBeans/Ant Java desktop music player demonstrating OOP, Swing-style UI screens, controller/service/DAO layering, MySQL integration, users, songs, playlists, liked songs, and account workflows.

Java · NetBeans · Ant · Swing · JavaFX Media · MySQL · DAO pattern

• DAO layer includes user, login, songs, playlists, password reset, liked songs, and admin access classes.
• Controller and service packages separate application coordination from UI forms and database calls.
• MySQL schema includes users, songs, playlists, liked songs, and relationship tables.

React Native/Expo + FastAPI civic service platform with role-based workflows, public service modules, notifications, provider/admin operations, and verified guidance/eligibility logic.

React Native · Expo · TypeScript · FastAPI · Python · SQLAlchemy · Pydantic

• Expo/React Native TypeScript mobile app with file-based app routes, hooks, typed APIs, auth token storage, forms, dashboards, and module screens.
• FastAPI backend with SQLAlchemy/Pydantic schemas, JWT auth, Alembic migrations, tests, role/permission checks, notifications, provider/admin operations, and service routers.
• Public-service modules include Aaja Chha, Paani Palo, Aspatal Aaja, Ek Choti, Kaam Ko Din, Sahayata Patra, and Khad Nyaya.

React/FastAPI KYC workflow using GPT-4o Vision for document extraction, classification-style review support, face verification analysis, persistence, and contextual assistance.

React · Vite · Tailwind · Zustand · FastAPI · SQLAlchemy · PostgreSQL

• GPT-4o Vision integration is present in OCR/document extraction and face-analysis service code.
• FastAPI endpoints separate OCR, KYC, face verification, and chat workflows.
• Async SQLAlchemy models persist KYC records, documents, chat messages, and face verification data.

Distributed AI security platform with Rust/Axum API, Python CUDA ML sidecar, LLM Guard, Garak, gRPC, Redis, PostgreSQL, Docker Compose, Nginx, SSE, and a Next.js dashboard.

Rust · Axum · Python · LLM Guard · Garak · gRPC · PostgreSQL

• Rust/Axum API uses SQLx/PostgreSQL, Redis, JWT, API-key middleware, rate limiting, and event/log endpoints.
• Python ML sidecar wraps LLM Guard real-time scanning and Garak vulnerability scanning behind gRPC.
• Docker Compose defines Nginx, frontend, Rust server, PostgreSQL, Redis, and GPU-only ML sidecar services.

Experimental browser productivity tooling exploring reference organization and document workflow automation through WebExtension APIs.

TypeScript · WebExtension APIs · Webpack

• Explores TypeScript WebExtension workflows for document and reference-management tasks.
• Uses browser extension APIs rather than presenting third-party document editors as fully controllable surfaces.

AI-focused personal engineering experiment currently in early development.
