I'm an AI developer and AWS Certified Solutions Architect with 6+ years of production experience across web, AI/LLM systems, and AWS cloud infrastructure. I work as a Full-Stack AI Engineer at Arithmiks, leading delivery on multi-tenant SaaS, fintech platforms, and AI-augmented tooling. Alongside that, I've delivered 20+ end-to-end products as a top-rated freelancer on Upwork and Fiverr: healthcare platforms, e-commerce ecosystems, CAD tools, and 3D viewers, on time and within scope.
My current focus is production LLM engineering: Retrieval-Augmented Generation (RAG) pipelines, agent workflows, structured outputs, and provider failover across Anthropic Claude, OpenAI GPT, and Google Gemini. As an AWS Certified Solutions Architect, I design and ship AWS serverless systems: Lambda, EventBridge, DynamoDB, S3, CloudFormation, and Terraform.
Recent production work includes PROMPTLY SOCRATIC SPECS, SBA LOANS HQ, and QUANTA AI DASHBOARD. Each case study covers the architecture, decisions, and outcomes in detail.
I'm based in Lahore, PK (UTC +5, Asia/Karachi) and work remote-first across EMEA and US-East timezones. Open to senior individual contributor and tech lead roles, contract and consulting engagements, and 0→1 MVP builds where reliability and shipping speed both matter.
