◆  About Me

I am a versatile Full-Stack Software Engineer and CEO with 3+ years of experience building scalable web applications, mobile apps, AI systems, and distributed infrastructure — from ground-level architecture to shipped product.

Currently leading EXO-Δ (digital transformation agency), driving B2B growth at TekScaleUp, and steering 3DEVS — while pursuing a B.S. in Computer Software Engineering at SZABIST Islamabad (Grade: A+).

My work spans the full spectrum: production Laravel/Django/Next.js applications, PyTorch transformers built from scratch, quantum circuit simulators in NumPy, Raft consensus implementations, and real-time collaborative systems using CRDTs. I don't use frameworks as black boxes — I understand what's underneath.

🧠  RAG Reasoning Engine

Multi-document retrieval-augmented generation with cited source attribution. Bridges unstructured corpora to structured, verifiable answers.

Python PyTorch FastAPI Vector Search

⚡  Collab Editor CRDT

Real-time collaborative text editor using WebSockets and LWW-CRDT conflict resolution. Multiple simultaneous users with zero data loss and elegant merge semantics.

TypeScript WebSockets CRDT Distributed Systems

🏛️  Raft KV Store

3-node Raft consensus simulation — leader election, log replication, and fault tolerance. A distributed key-value store that survives node failures with full consistency.

Python Distributed Systems Consensus Fault Tolerance

📖  NanoGPT-2

GPT-2 transformer in pure PyTorch — attention heads, positional encodings, autoregressive generation — built from mathematical first principles, not wrappers.
