Software Engineer | Full-Stack Development & Applied AI Integrations

I'm a Software Engineering student at FAST-NUCES (Expected May 2026) with a strong focus on building production-grade web applications and AI-powered platforms. I thrive at the intersection of high-fidelity UI/UX design and scalable backend architecture—turning complex business requirements into pixel-perfect, performant systems.

• 🧠 Building low-latency AI pipelines (RAG, Voice AI, LLM Orchestration)
• 🏗️ Architecting secure, multi-tenant systems (PostgreSQL RLS, Supabase)
• 🎨 Bridging the gap between Figma designs and production-ready React/Next.js code
• 🚀 Shipping SaaS products from 0 → 1

🔹 Voice AI Agent for Real Estate | FastAPI, WebSockets, Python, RAG, STTs, LLMs, TTSs

• End-to-end, Urdu-native voice AI platform for the Pakistani real estate market with always-on inbound/outbound agents.
• Engineered an extensible agent versioning system for dynamic customization of identity, RAG configs, and voice settings.
• Achieved 400–700ms conversational latency through streaming pipeline orchestration and TTS optimization.
• Integrated ElevenLabs, Deepgram, OpenAI, and local models with Voice Activity Detection (VAD).

🔹 LAPIS — AI Brand Strategy SaaS | Next.js, Node.js, Supabase, Gemini API, AWS, Lemon Squeezy

• AI-powered platform generating comprehensive brand playbooks, visual identities, and competitive sentiment analysis.
• Secure multi-workspace architecture using Supabase Row-Level Security (RLS) and AWS S3 pre-signed URLs.
• Orchestrated sequential LLM pipelines via Gemini API; integrated Lemon Squeezy for global subscription billing.

🔹 LEAP — AI Social Media Automation | LinkedIn API, Next.js, Express, Redis, LLMs

• AI-powered platform automating "build in public" workflows with direct LinkedIn API programmatic publishing.
• Async scheduling pipeline via Redis queues with retry logic, reducing manual drafting/publishing time by ~80%.
• Low-latency LLM orchestration layer generating context-aware posts optimized for professional networking algorithms.

🔹 Multi-tenant LMS | React, PostgreSQL, FastAPI, React Native

• led engineering for a scalable multi-tenant Learning Management System supporting 1,000+ concurrent students.
• Implemented PostgreSQL RLS for strict data isolation across 20+ tenant environments.
• Built a cross-platform mobile app for US business listings with FastAPI endpoint latency optimized to <300ms.
