Hi, I'm Ghulam Mustafa 👋

5+ years of experience architecting high-scale distributed systems, mission-critical mobile apps, and production agentic AI workflows.

Open to Senior/Staff Engineering Roles, AI Systems Architecture, and High-Impact Technical Collaborations.

Metric	Context & Accomplishment
100K+ Active Users	Scaled Udhaar Book — Pakistan's #1 digital ledger application
50% API Latency Cut	Re-engineered Node.js & PostgreSQL core services at Dastgyr
99.9% Uptime SLA	Production architecture for Lumida Wealth (AI-driven US investment platform)
40% Faster App Startup	Optimized React Native runtime, Hermes engine, and bundle assets at scale
3× Traffic Scaled	Architected zero-infrastructure-cost expansion for high-volume transactions
30% Engagement Growth	Re-designed enterprise B2B mobile UX workflows for Unilever Roll
Crash Rate: 5% → 0.2%	Root-cause native module resolution and automated telemetry instrumentation

🏆 Honors & Awards

Autonomous Agents & Verification: Architecting closed-loop agentic workflows with deterministic verification layers, sandboxed tool execution, and self-healing environments.
Production LLM Reliability: Eliminating hallucinations through pre-LLM deterministic gates, confidence calibration, frozen state snapshots, and rigorous eval benchmarks.
Distributed Backends & Microservices: High-throughput REST/GraphQL architectures using Node.js, NestJS, and advanced PostgreSQL query optimization.
Resilient Mobile Engineering: Production React Native & Expo architectures handling hundreds of thousands of transactions.

What it does: Autonomous CLI agent that detects, diagnoses, and fixes broken local dev environments. Runs bash commands inside secure, ephemeral Docker sandboxes with a deterministic verification layer to test and prove fixes against test suites before completing.
Key Metric: Achieved an 80% autonomous recovery rate across benchmark suites.
Stack: TypeScript · Node.js · Docker Sandboxing · Agentic Verifier Loops

What it does: Analyzes client postings, blocks scams and low-budget jobs via deterministic pre-LLM gates, calibrates confidence (APPLY / MAYBE / SKIP), and writes grounded, hallucination-free proposals.
Key Metric: Tested against a 28-job Golden Benchmark with 96.4% decision accuracy and 100% scam/injection resistance.
Stack: Next.js 16 · TypeScript · Prisma · SQLite · OpenAI API

What it does: Evaluates applicant profiles against 1,454+ visa routes across 70+ countries. Uses a deterministic rules engine grounded in official government sources, real-time "What-If" parameter simulation, and an AI chat copilot.
