AWS Lookout for Equipment Geospatial Data Analytics on AWS Applied AI / ML

Career Journey

Ensono

Chief Technology Advisor

Led enterprise application integration and modern data stack architecture, connecting legacy infrastructure to cloud-native systems on BigQuery and Snowflake, with event-driven backbones on Kafka and Camel.

Analytics project: Built a RAG system over infrastructure data so maintenance and inventory questions like what's end of life, what's running on old hardware, or what's still on an outdated software version could be answered instantly instead of hunted down manually.

Amazon Web Services

Technical Account Manager → Solutions Architect II → Solutions Architect III

Seven years across three roles: cloud migration leadership, real-time IoT ingestion pipelines, and technical evangelism for AWS's newest services presented directly to enterprise leadership.

Analytics project: Built a Salesforce analytics integration for my team that pulled territory and account activity into a single dashboard covering the whole book of business.

Savvis / CenturyLink / Lumen

Network Engineer → Head of Service Delivery (India) → Solutions Architect / Sr. Sales Engineer

Network engineering and data center migrations early on, then two and a half years in Bangalore standing up and leading a 30+ person offshore operations team, then enterprise technical sales.

Analytics project: Built two internal applications off the CMDB: one that read hardware and request-type data to auto-generate deployment scripts for engineers, and one for management that tracked build queue depth, build type, and estimated completion time to show real-time engineering team load.

IBM

Project Manager

Ran technical deployment and inventory tracking for a nationwide Point-of-Sale hardware refresh across field sites.

Analytics project: Built a C# application that read field-tech survey results and automatically assembled the hardware ordering list for the rollout.

AWS Lookout for Equipment, wind turbines

AWS Lookout for Equipment is a managed ML service that ingests sensor and time-series data from industrial equipment and learns what normal operation looks like, so it can flag abnormal behavior early without requiring in-house ML expertise to build or maintain a model.

Published Work in Geospatial & Data Analytics

A selection of technical blogs and projects, most written for AWS, that map directly onto energy-sector problems: spatial data at utility scale, real-time sensor and SCADA integration, and turning raw infrastructure data into something a team can actually query.

Leveraging the Power of Esri's ArcGIS Enterprise Through Amazon Redshift

Combining a spatial engine with a data warehouse the same pattern behind joining asset location data to cost and consumption data at utility scale.

Serverless GIS with Amazon S3 and Open Data

A low-cost, serverless pattern for publishing spatial datasets the same shape as serving public energy and climate data without standing up a GIS server.

Integrate OSIsoft PI and Esri ArcGIS on AWS for Real-time Utility Dashboards

Grid sensor (SCADA) data fused with geospatial asset data in one live dashboard written directly for a Power & Utilities audience.

Integrating AWS IoT with ArcGIS Velocity

Streaming IoT sensor data straight into spatial analysis the same real-time ingestion problem field equipment and smart-meter data pose.

GeoAnalytics Engine with Amazon EMR

Big-data spatial analytics across huge datasets the scale a national transmission or generation footprint actually needs.

Geohashing on S3 with Amazon Redshift

A partitioning strategy for large geospatial datasets in a data lake or warehouse directly applicable to asset and outage data queried by region.

Open Data on AWS

Sourcing public datasets (weather, climate, demographic) to enrich internal energy and load-forecasting models.

Climate Next Sustainability

Climate-impact geospatial modeling for The Nature Conservancy the same "data into a decision" pipeline energy sustainability reporting needs.

Llama on Windows

Running an open-source LLM locally relevant wherever OT and utility networks can't call out to a cloud API.

Serverless Lambda RAG with LlamaIndex

An earlier, serverless version of the same retrieval-augmented approach behind the infrastructure RAG work above.
