Engineer
Hey!
I’m Ahmad, a senior software engineer based in Lahore, working remotely with teams worldwide. I build scalable cloud, web and mobile products, and evaluate the AI models that write code.
Today I’m a Senior AI Developer at Stixor Technologies, where I took CattleXpert from concept to nearly 10,000 users. Before that, at Turing, I trained and reviewed model-generated code for Google Code LLM and SWE-bench.
From idea to launch. AI-native products built to ship fast, scale cleanly and hold up in production, driven by clear thinking and systems that stay simple.
How I can help you ship.
Whether you need a single feature or an end-to-end product, I plug in where you need me most.
Full-Stack Web Apps
End-to-end products with React / Next.js front ends and robust Node, NestJS or Python back ends, architected to scale and built to last.
Mobile Apps
Cross-platform iOS & Android apps with React Native, with fast, native-feeling experiences from a single, maintainable codebase.
AI & Agentic Systems
LLM integrations, RAG pipelines, chat assistants and autonomous agents using OpenAI, Bedrock, Pinecone and Hugging Face.
Cloud & DevOps
AWS infrastructure, Docker, CI/CD pipelines and multi-tenant architecture, deployed reliably and ready to scale.
Performance & Scaling
Profiling, query optimization, caching with Redis, lazy loading and code splitting, making slow products fast.
API & Auth Architecture
REST & GraphQL APIs, SSO, JWT / OAuth 2.0 and AWS Cognito, secure, well-documented and easy to build on.
The tools I reach for.
A full-stack toolkit sharpened across fintech, healthcare and AI products, from pixel-level frontend to cloud infrastructure.

It’s really amazing how you can find a designer whose designs you actually really like from the first trials. Raza is one of the greatest designers on Upwork. Second time I hire him and definitely will not be the last time.
Ahmad is an exceptional engineer. He took ownership of our backend architecture and delivered a scalable system ahead of schedule. Communication was clear and proactive throughout.
One of the few developers who truly understands both the AI side and production engineering. Our LLM assistant shipped fast and worked reliably. Highly recommended.
Reliable, fast and detail-oriented. Ahmad rebuilt our mobile app in React Native and the performance gains were immediate. We’ll absolutely work with him again.
