DATA PLATFORM & AI ENGINEERING
Andalib Ansari

End-to-end data platforms, wired for AI agents.

I build the full path from raw events to a trusted warehouse - orchestration, quality gates, modeling - then wire agentic AI on top of it. I love turning data into insights that help businesses make better decisions, whether that's a production data platform or an automated digital presence audit that tells a business owner exactly where they stand.

What I build, end to end

Not a generalist list — this is the specific stack I've shipped in production, repeatedly.

End-to-End Data Platform Design

Architecting the full path from raw ingestion to governed, trusted data - data lake, warehouse, catalog, and lineage as one coherent platform, not disconnected tools.

AWS S3Data LakeData CatalogData Lineage

Airflow Platform Setup

Standing up production-grade Airflow - custom operators and plugins, DAG authoring standards, code-review conventions, and on-call runbooks that scale as teams grow.

Apache AirflowCustom OperatorsDAG StandardsPagerDuty SOPs

Custom Data Quality Server

Building in-house data quality services from scratch - automated checks that catch schema drift, null violations, and SLA breaches before they hit downstream consumers.

Data Warehouse Modeling

Designing dimensional models and star schemas built for fast, trustworthy BI — the layer between raw pipelines and the dashboards people actually make decisions from.

AI Apps on Warehouse & Event Data

Building agentic AI applications with n8n and LangChain directly on top of warehouse and event-stream data - RAG assistants, natural-language query agents, and automation workflows.

n8nLangChainRAGEvent DataData Warehouse

Data Warehouse Migration

Moving traditional, on-prem data warehouses to modern cloud platforms - replatforming schemas, pipelines, and workloads with minimal downtime and validated parity.

Data Analytics

Turning warehouse and event data into dashboards, metrics layers, and ad-hoc analysis that actually drive decisions - not just reports nobody opens.

1:1 / Group Data & AI Engineering Coaching

Mentoring engineers and small teams on data platform fundamentals and applied AI - architecture reviews, career guidance, and hands-on pairing, one-on-one or in groups.

Digital Presence Audit

AI-analysed monthly audits that show local businesses how they look on Google, social and AI search, how they compare with competitors, and exactly what to fix first. Each report is tailored to the business.

How an engagement runs

01 / Discover

Scope the work

A short call to understand your data platform, pipelines, or digital presence — and agree what a successful engagement looks like.

02 / Deliver

Build or report

Hands-on delivery — platform architecture, Airflow setup, a data quality server, warehouse migration, an AI agent, or your first Digital Presence Audit report.

03 / Handover

Support & next steps

Documentation and runbooks for technical builds, or a walkthrough of your action plan for audit clients — plus a short support window either way.
