    AI Outbound Calling and Lead Qualification System

    A system I built that calls a list of consented contacts with an AI voice agent, holds a short qualifying conversation and records every result as a tracked outcome or lead. A NestJS API runs the dialing, compliance checks and webhooks, and a Next.js dashboard with a built-in AI assistant lets the owner run campaigns and ask for reports in plain language.

    Salon Booking Marketplace — Multi-Salon Platform

    A multi-salon booking marketplace I designed and built for Pakistan. Clients find nearby salons on a map, choose a barber, service and time, and book at the salon or as a home visit. Salons run staff, schedules and earnings from their own dashboard, and the platform collects a commission per completed booking through daily settlements.

    ReviewLens — Review and Returns Analysis for Stores

    ReviewLens (working name) is a SaaS I built for online stores. It reads a store's customer reviews, returns and competitors and turns them into a short report: what customers complain about, which products cause the most problems and what to fix first. All numbers are computed in code, and AI only classifies text and explains the results.

    SimRelay — Android SMS Gateway Using Your Own SIM

    SimRelay is a small Android app I built that turns my own phone into an SMS gateway. It checks a web server for pending messages, sends each one as a normal text from the phone's SIM card, and reports the sent and delivered status back, so a small web app can send booking confirmations without a paid SMS provider.
