Md Jahid Hasan — architecting LLM applications, autonomous agents, RAG pipelines and n8n automation for enterprise system integration. From proof-of-concept to hardened, observable deployments.
One hand from architecture to delivery — so systems ship, integrate and keep working.
Production-grade LLM apps: prompt and context design, structured output, evaluation harnesses, guardrails, caching and cost control.
Tool-using agents and orchestrated multi-agent workflows with planning, memory, retries and human-in-the-loop checkpoints.
Chunking, embeddings, hybrid search and re-ranking pipelines that stay accurate as the corpus grows.
Event-driven automation connecting CRMs, databases, queues and APIs — with observability and error handling built in.
Wiring AI into existing stacks: auth, data boundaries, audit logging, rate limits and safe rollouts.
Company-wide knowledge assistant over 200k+ documents with hybrid retrieval, inline citations and role-based access. Placeholder case study.
Autonomous research crew that plans, gathers, verifies and drafts — with human approval gates.
120+ workflows replacing manual ops across sales, finance and support.
Tracing, evals, cost dashboards and regression alerts for every model call.
Extraction and classification service handling messy PDFs at scale.
How the practice grew
Built forecasting and classification models; learned what breaks between notebook and production.
Designed event-driven pipelines and internal tools; standardised on n8n for orchestration.
Shipped the first retrieval-augmented assistants and structured-output services.
Owned architecture for agentic systems and enterprise AI rollouts end to end.
Focused on evaluation, observability and safe integration at organisation scale.
A predictable path from idea to running system.
Clarify the job-to-be-done, constraints, data and success metrics before any code.
Design the system, then prove the risky parts with a thin vertical slice.
Implement against real systems — auth, data boundaries, queues, APIs.
Eval sets, guardrails, load and failure testing, cost and latency budgets.
Ship with dashboards, runbooks and a team that can operate it without me.
Placeholder quotes — swap for real ones.
Tell me the problem and the constraints. I'll tell you the shortest credible path to a running system.
The more context you give, the more useful my first reply will be.
