# Hamza Shah

## Professional summary

Innovative software developer and cryptography engineer with strong expertise in building secure systems, privacy-first applications, and production-grade cryptography. Experienced in applied cryptography (RSA, ECC, AES, Kyber, Falcon, Dilithium, NTRU), blockchain architecture, Tor-based anonymous networking, modern full-stack development, and cross-platform mobile app development (React Native, Flutter). Focused on mathematically sound security, clean implementation, and high-impact solutions.

## Experience

### Full Stack Developer — Lumariom

*May 2026 — Present*

- Work on the frontend with Next.js and React Query for data fetching, caching, and state management.
- Develop backend services with real-time socket connections for seamless communication.
- Handle email services including sending, verification, and management.
- Implement end-to-end encryption using ECC (Elliptic Curve Cryptography) for secure data transmission.
- Manage and deploy cloud infrastructure on Oracle Cloud.
- Work on continuous feature enhancements and performance optimization.
- Use Git for version control and collaboration with branching and versioning practices.
- Follow Figma UI/UX designs to build responsive, user-friendly interfaces.

### Full Stack Developer & AI Engineer — MetaLLM (metallm.tech)

*2026 — Present*

- Built a multi-model AI aggregator platform featuring smart routing, debate mode, and usage-based monetization.
- Built an intelligent routing layer that analyzes query complexity and dynamically dispatches prompts to specialized AI models.
- Designed a multi-round debate system where models challenge and refine each other's responses, with a neutral AI judge.
- Developed a React + TypeScript frontend (Vite, TanStack Query, shadcn/ui) with an Express.js/Node.js backend.
- Designed a PostgreSQL schema with Drizzle ORM and built a usage-based billing system supporting fiat and cryptocurrency.
- Deployed on cloud infrastructure and manage a live Android app with active subscribers.

### Lead Blockchain Developer & Cryptography Engineer — [Qbitcoin](https://github.com/Hamza1s34/Qbitcoin), Islamabad, ICT

*January 2024 — February 2026*

- Built a quantum-resistant blockchain in Python with full-node implementation, consensus engine, Merkle tree verification, and P2P peer discovery and block propagation.
- Designed JSON-RPC and gRPC API endpoints for wallet integration, block explorer queries, and exchange connectivity.
- Implemented Falcon-512 lattice-based digital signatures, replacing ECDSA — engineering key-generation, signing, and verification pipelines for post-quantum security.
- Architected and deployed production infrastructure on Linux, Oracle Cloud, AWS, and Azure using Git, Nginx reverse proxy, and PM2 process management.
- Developed a desktop wallet, mobile wallet (React Native), and blockchain explorer.

### Systems & Cryptography Engineer — [Gumnam](https://github.com/Hamza1s34/Gumnam) (Open Source)

*2025 — Present*

- Built a serverless anonymous messenger using Rust + Tor hidden services, eliminating reliance on centralized backend servers.
- Implemented end-to-end encryption (Ed25519/X25519 ECIES + ChaCha20-Poly1305 + HKDF) with signed protocol messages and strict reject-on-fail validation.
- Developed a cross-platform desktop client (Flutter/Dart) integrated with Rust core via flutter_rust_bridge — chat UX, media messaging, reactions, pinning, and notifications.
- Designed offline message delivery fallback via embedded libp2p Kademlia DHT for intermittent peer availability.
- Engineered Tor bootstrap/runtime management, onion-address identity verification, local-first SQLite persistence, and secure data-clearing workflows.
