I'm Samiullah, a senior AI engineer. Two years of production work across content automation, multi-agent commerce, retrieval, and inference.

I got into production AI through retrieval and inference. At N6 Solution I built a RAG pipeline with multi-query expansion, decomposition, fusion, and reranking, and a FastAPI service answering live traffic in sub-second time.
Since then I've moved up the stack. At Revnix I'm the sole backend architect for rext.ai, and at TheBotLab I lead the architecture of a seven-agent Shopify platform, each agent with its own tools and error boundary across 40+ live integrations.
The common thread is keeping systems alive in production: state in PostgreSQL and Redis, retries and error boundaries at the right places, and a human approval step where judgment matters.
I also write the tooling I need. langctl is my open-source CLI for scaffolding and deploying LangChain and LangGraph agents, on PyPI with 14+ releases. Next up: AgentGenesis, a framework where agents configure and spawn other agents.
Architecture, deployment, schema migrations, monitoring. I stay responsible from the first diagram to the production deploy.
rext.ai pauses for outline approval before a word is written. The parts that need judgment stay with a person.
Pipeline evaluation and monitoring are part of the build, not a follow-up task.
The agent communication standards I defined at TheBotLab were adopted across every subsystem on the platform.
