Case studies
The work behind the words.
Data, cloud, and AI engagements — the problem, the approach, and the number that moved. Anonymised, every outcome real.
A modern, PCI-compliant data lake on AWS — built from scratch
Billions of marketing transactions needed a secure, scalable home without the cost and limits of the previous approach.
A secure, multi-tenant credit-decisioning data lake, built from heterogeneous source files
Inconsistent client source files had to become governed, tenant-isolated data without losing traceability.
A production data warehouse that unifies a fragmented fleet-operations estate
Agreements, maintenance, fleet-management, legacy back-office, and telematics data lived in separate systems with no unified view.
Cutting $50K a month from a Snowflake bill — without losing performance
Snowflake spend had climbed through over-provisioning, idle capacity, and retention choices that did not match actual workload needs.
Teradata to Snowflake, at grocery-retail scale
A 180TB Teradata estate carried high running cost while critical reporting workloads faced performance pressure.
Turning a 40-million-SKU item master into data buyers could actually find
Sparse, inconsistent product identifiers kept a 40-million-SKU catalog from matching reliably to sales and demand.
Real-time lead scoring that puts every lead in front of the right rep
One heuristic qualified every lead, burying stronger prospects and wasting limited sales capacity.
The AI recommendation engine behind $6.5M in incremental margin for a global parts distributor
Historic-sales shopping lists missed live demand and left valuable supply channels underused because trust could not be assessed systematically.
Cloud FinOps: turning 400+ accounts of spend into actionable insight
Spend across 400+ cloud accounts was difficult to interpret, with manual reporting obscuring concrete optimisation opportunities.
A SOAR platform that governs 400+ AWS accounts continuously
A Fortune 500 AWS estate needed one continuously audited posture across hundreds of accounts, regions, and policy types.
Hardened golden images, automated across 400+ AWS accounts
Golden-image creation and distribution had to stay secure and consistent across hundreds of accounts and many operating-system variants.
Re-platforming an IoT vessel-tracking system to AWS — and tripling its capacity
The original vessel-tracking architecture could not absorb rising device traffic without bottlenecks and single points of failure.
A templated, governed multi-account AWS foundation
Each new client environment needed repeatable isolation, access control, encryption, and billing without manual rebuilding.
A multi-tenant, cloud-native platform for a B2B SaaS product
A scaled-up prototype needed true multi-tenancy, flexible client ingestion, and an AI layer that could evolve with new models.
