✦ Employed

Building production Flutter applications from detailed design systems, working directly with design and backend teams to ship features that stay fluid and crash-free.

Responsibilities & impact
High-performance UI: translated high-fidelity Figma designs into precise Flutter widget trees with 60fps micro-animations and responsive layouts.
Reactive state architecture: modular state with Riverpod and decoupled, guard-protected routing via GoRouter.
Supabase & cloud sync: OAuth and email authentication flows, PostgreSQL storage, and realtime database synchronisers.
Offline-first caching: encrypted Hive storage and Flutter Secure Storage for offline access and token safety.
Monetisation & deep linking: Google Mobile Ads SDK placements and deep-link routing schemes.

Sole Engineer — Tripline

2026 · AI travel platform, built end to end
✦ Own product

Designed, built and shipped an entire AI travel companion alone — mobile client, AI layer, database schema and a web moderation console. Every architectural decision on this one was mine to make and mine to live with.

What I owned
AI itinerary engine: Groq Llama 3.3 70B behind a strict JSON contract, with schema validation before anything reaches the UI.
Data model & security: PostgreSQL schema with row-level security so a user can only ever read their own trips.
Map discovery: OpenStreetMap integration with custom styling, marker clustering and location caching at 60fps.
Admin console: a Flutter Web moderation panel for reported content and system health.

Lead Developer & Solo Team Lead — LectureMind

2026 · Voice-First Academic Knowledge Engine
✦ Hackathon solo build

Engineered LectureMind from scratch as a 100% solo developer and team leader for the Lablab.ai AssemblyAI Voice Agent Hackathon. Architected a voice-first academic knowledge synthesis engine that captures live lecture audio over WebSocket, strips disfluencies via Groq LLM, and produces exam-ready structured study guides, vector PDFs, interactive mind maps, and Socratic quizzes.

What I owned
Live speech streaming: AssemblyAI Universal-3.5 Pro streaming WebSocket integration with acoustic vocabulary boosting for bilingual Pakistani English-Urdu code-switching and technical jargon.
Neural STT post-processing: Groq GPT-OSS-120B reasoning pipeline to remove conversational fillers and format raw utterances into clean academic prose with 1-tap term refinement.
Neumorphic UI & multi-format export: Soft UI dark navy design system, vector PDF compiler, HTML5 Canvas JPG concept graph rasterization, and interactive Bloom's taxonomy quiz gauge dials.

Where the fundamentals came from. The Smart Car Parking System was the project that taught me object-oriented design properly — inheritance hierarchies that made sense, state that survived a restart, and a billing engine that had to be exactly right.

Applied work
Smart Car Parking System: a multi-floor Java desktop application with a live slot grid, sequential ticketing and an automated tariff engine.
Core computer science: data structures, algorithms, database systems, operating systems and AI principles.
Alongside the degree: 11 verified certifications from Google, IBM, Meta, Michigan and CU Boulder.
