About
Senior engineering judgment with an AI-first builder mindset.
I am a Principal Software Engineer based in Lahore, Pakistan, with experience across full-stack product development, Python back ends, JavaScript front ends, REST APIs, AWS serverless systems, and delivery leadership.
My current focus is building software that uses AI as part of the product fabric: LLM integrations, retrieval workflows, AI agents, chatbots, and automations that make teams faster without making systems fragile.
I like working with founders, product teams, and recruiters who care about practical innovation: learning quickly, owning architecture, collaborating clearly, and shipping reliable software that users can actually trust.
What I build
From AI prototypes to scalable production systems.
RAG and RagFlow systems
Build retrieval pipelines with embeddings, vector databases, and semantic search that connect private knowledge to LLM interfaces.
Chatbots and automation
Create chat-driven workflows, Python automations, and integration layers that reduce manual work and improve response speed.
Full-stack applications
Ship user-facing systems with Vue, React, Next.js, Node.js, Express, Django, FastAPI, and clean API contracts.
Cloud-native back ends
Design serverless and event-driven systems with AWS Lambda, EC2, S3, CloudFormation, Step Functions, SNS, SQS, and CloudWatch.
Fractional CTO support
Help teams shape technical strategy, own architecture, mentor engineers, and turn ambiguous AI product ideas into maintainable systems.
Experience
A track record across product engineering, cloud, and team delivery.
