Experience & Education

Antioxida (task-based contract), Health-tech

Migrated 30+ database models from MongoDB to PostgreSQL with zero data loss, growing the Prisma schema past 1,000 lines, and moved the entire backend from JavaScript to TypeScript.
Designed and built 230+ REST endpoints (90+ GET, 50+ POST, 50+ PUT/PATCH, 40+ DELETE) powering the product, order, and recommendation systems.
Built an advanced filtering engine for the recommendation system and wrote hundreds of lines of raw SQL/PL-pgSQL to implement research-based calculation logic.
Built internal visualization tools so non-technical specialists could configure recommendation rules without code, plus the full frontend dashboard in SvelteKit and Tailwind CSS.
Integrated Stripe for subscription billing.

Spacr (task-based contract), Cross-border delivery marketplace

Designed and built the real-time chat backend using Node.js, ws, and TypeScript.
Owned the peer-to-peer package delivery feature end-to-end: posting and accepting flows for travelers carrying packages to their destination.
Migrated the legacy JavaScript backend to TypeScript, adopting a 500+ line Prisma schema over raw SQL.
Built a wallet system with escrow logic to guarantee payment transfer tied to delivery completion, and integrated Stripe for in-app payments.
Integrated Bykea (Pakistan) and Careem (UAE) for deliveries, and built a custom in-house delivery solution for the UAE (backend plus personnel dashboard) to work around Careem's distance limitations.

EEG-Controlled Prosthetic Arm (Graduation Project)

Owned the full software/ML pipeline: data preprocessing, model training, and a real-time inference application with signal buffering, windowing, and confidence-gated command dispatch.
Benchmarked five deep learning architectures (EEGNet, ATCNet, DB-ATCNet, EEG-Inception, DCNet) against classical ML baselines, selecting DCNet for production based on accuracy-to-parameter-count tradeoff.
Surveyed more than 19 public EEG motor-imagery datasets against literature-defined criteria.
