Selected engineering work

A deeper look at products I built across mobile, backend, payments, realtime systems, maps, native Android flows, IoT, commerce, and modern web experiences. The goal here is to show actual execution depth clearly, especially on larger systems like AasPas.

Real app surfaces

DiscoveryAI chatTrackingPaymentsWallet

Flagship productSolo built

AasPas - Hyperlocal Service Marketplace

A full-stack React Native and Node.js marketplace for customers, workers, and admins. Includes native Android call screens, full-screen booking alerts, live worker tracking, route cache, multilingual AI booking assistance, payments, wallet settlement, worker earnings, support, reviews, and multilingual UX.

This is a solo-built flagship system that combines mobile product engineering, backend architecture, realtime sockets, native Android behavior, live location workflows, multilingual AI-assisted booking support, payment correctness, and operations-oriented business tooling.

Marketplace-grade payment engine

Minimum booking fee, online or cash booking flow, backend-owned payment truth, remaining amount collection, worker earnings, commission logic, wallet records, and settlement-oriented money movement.

Realtime tracking and location intelligence

Live worker location streaming, route caching, ETA and distance awareness, service-radius discovery logic, latest-location recovery, and controlled rerouting instead of wasteful map API calls.

Native Android communication layer

Incoming booking popups, native call activities, full-screen notification behavior, lock-screen entry, ongoing-call return path, speaker and earpiece control, and background-safe calling UX.

Operational depth beyond the main app

Support, reviews, notifications, version control, admin oversight, video/tutorial management, service monitoring, and business-side visibility across the marketplace lifecycle.

Multilingual AI booking assistance

A conversational booking-help layer can understand user intent across languages, assist with service discovery, and automate booking actions such as guiding or initiating requests for electricians and other workers.

Realtime control

Energy analytics

IoT product system

AasPas Smart Box - Connected IoT Control Platform

A connected smart-switch product that combines ESP32 hardware, a cloud backend, a web dashboard, a mobile app, relay automation, energy analytics, and recovery-focused device behavior.

This project shows that I can build beyond app-only software into end-to-end IoT systems where hardware identity, cloud state, realtime transport, energy data, and user control all matter together.

Key features

Device claiming and user ownership

3-channel relay control

Per-relay timer automation

Daily and one-time schedules

Realtime sync across device, app, and dashboard

Energy units and cost tracking

Power-loss pause and resume behavior

Monthly energy overview and outage history

Hardware-to-cloud control path

The system is not just UI. ESP32 devices, cloud APIs, realtime sockets, MongoDB state, and user-facing apps all stay connected through one control pipeline.

Automation engine per relay

Each relay supports its own timer, daily schedule, one-time schedule, and independent control state instead of a single device-wide toggle.

Energy and cost intelligence

The product tracks wattage, runtime, units, cost, monthly summaries, and relay-level energy history so the switch behaves like an analytical home-automation product.

Resilience under real conditions

Heartbeat monitoring, offline detection, power-loss pause/resume, HTTP fallback, and outage history make it much more robust than a hobby-only IoT demo.

Commerce product

Mushdelight - Premium Food Commerce

Premium food commerce platform with customer auth, OTP verification, order lifecycle screens, product reviews, subscriber communication, and admin product controls.

Built to show complete commerce execution across customer accounts, Mongo-backed catalog and order data, review systems, communication workflows, and business-facing product operations.

Key features

Signup, login, OTP verification, and password recovery

Catalog and cart journey

Checkout and order lifecycle screens

Order tracking and cancellation

Review and rating support

Subscriber and contact flows

Admin-side product and settings operations

Commerce beyond a landing page

The project connects product discovery, cart, checkout, orders, tracking, cancellation, and reviews into a believable customer commerce loop instead of stopping at a hero section.

Customer account lifecycle

Login, signup, OTP verification, forgotten-password recovery, and profile-linked order visibility give the product a fuller account system than many demo storefronts.

Business communication layer

Contact submission, subscriber collection, and email-oriented workflows make the website useful for ongoing brand communication as well as order capture.

Operational backend thinking

Models and APIs for products, orders, reviews, settings, contacts, and subscribers show backend structure that supports day-to-day business operations.

Retail commerce system

Lizz-Shop - Retail E-commerce Platform

Full-stack shopping platform with category browsing, search, size and color variants, JWT-backed sessions, MongoDB user state, wishlist persistence, and cart persistence.

This project demonstrates practical ecommerce engineering through cookie-authenticated sessions, user-specific shopping state, merchandising sections, and variant-aware retail browsing.

Key features

Category browsing and search

Wishlist and cart persistence

Size and color variant selection

JWT plus cookie-authenticated sessions

MongoDB-backed product and user state

New arrivals, trending, and BOGO sections

Responsive storefront layout

Shopping-state depth

Wishlists, carts, cookie-authenticated sessions, and MongoDB user state make the product stronger than a purely visual store mockup.

Variant-aware browsing

Product detail pages handle size and color selections so the purchase flow feels closer to real retail behavior.

Merchandising logic

New arrivals, trending sections, and BOGO-oriented APIs show that the project includes merchandising thinking, not only CRUD data rendering.

Full-stack separation

A dedicated backend service with JWT and cookies proves this is structured more like an actual application stack than a frontend-only prototype.

Realtime web product

AasPas Private Theater - Realtime Watch Party Website

A realtime watch-party system with host-controlled playback, shared room links, WebRTC voice, chat, reactions, multi-source video support, and Mongo-backed recovery.

This project shows depth in collaborative media engineering: playback authority rules, player abstraction, room persistence, source validation, and social interaction all working together in one product.

Key features

Private room creation and join-link flow

Host-only synchronized playback control

Realtime room chat and emoji reactions

WebRTC voice communication

Source support for YouTube, Drive, MP4, HLS, Streamable, and embeds

Playback recovery after refresh or buffering

Shared playback engine

This is more than a video page. It includes host-authority playback control, drift-aware synchronization, seek handling, and reload recovery so multiple viewers stay aligned.

Source compatibility layer

The product parses multiple source types, normalizes tricky links, inspects remote media responses, and gives users feedback before room creation when a link is not browser-friendly.

Collaboration stack

Voice chat, room chat, emoji reactions, guest presence, shareable room links, fullscreen chat overlays, and join identity persistence make the experience feel like a real shared room.

Persistence and cleanup

MongoDB stores room playback state, capped chat history, and member profiles while TTL rules and runtime resets keep temporary rooms manageable.

Key features

Twilio-based unanswered-call voicemail flow

Voicemail inbox with unread state

Greeting upload support

Caller number and duration visibility

Audio playback inside app

Hindi-first mobile experience

Telephony to app workflow

The interesting part is the end-to-end workflow: ring timeout, Twilio forwarding, greeting playback, recording capture, database save, and app inbox visibility.

Inbox behavior

Unread badges, timestamps, durations, caller numbers, and tap-to-play behavior make voicemail feel like a modern list-based product instead of a hidden telecom feature.

Greeting pipeline

Users can upload or associate greeting audio, which is an important part of making the experience feel personal and productized.

Cross-layer execution

This project mixes backend webhook handling, file storage, Mongo schemas, and mobile audio playback rather than living in a single frontend layer.
