Azure Data Lake Migration

Legacy on-premises warehouse was processing 50,000+ daily records on infrastructure built for 5,000 — reports took 6+ hours to generate. We migrated 15 years of historical data to Azure Data Lake, built real-time IoT ingestion pipelines for 50+ global facilities, and deployed Power BI dashboards for 15 business units across 3 continents.

How we did it

Week 1–2: Architecture review and data audit across 50+ global facilities

Week 3–12: Historical data migration, lakehouse setup, real-time pipeline build

Week 13–32: Power BI dashboards, UAT, phased rollout across all business units

Their team delivered what our internal team said would take 18 months — in 8. The real-time visibility across our global operations has transformed how we make decisions.

Databricks Data Platform Implementation

The trading platform was processing 2M+ daily transactions on legacy SQL Server — peak load caused 4–6 hour reporting delays and compliance teams were working off day-old data. We built a full Databricks lakehouse with Delta Lake, automated real-time trade ingestion pipelines, and Power BI dashboards for traders and compliance teams. Delivered 2 weeks ahead of schedule.

Cloud Infrastructure Modernization

Cloud infrastructure had grown organically over 5 years with no governance — 40% of resources were unused, security had 200+ unresolved findings, and deployments took 3–5 days. We conducted a comprehensive architecture review, implemented infrastructure-as-code with Terraform, containerized patient care applications with Kubernetes, and established CI/CD pipelines. Zero downtime throughout.

How we did it

Week 4–18: Terraform IaC implementation, Kubernetes containerization, CI/CD setup

Week 19–24: Phased migration, zero-downtime cutover, team handover and training

We had 200+ open security findings and deployments that took days. Six months later we have zero critical findings and deploy in under an hour. Remarkable work.

Customer Data Platform Build

Customer data was siloed across 8 systems — web analytics, CRM, order management, and marketing tools couldn't talk to each other. The company had zero visibility into customer lifetime value and personalisation was impossible. We built a unified customer data platform on Snowflake, implemented Airflow pipelines for real-time ingestion, ML models for customer segmentation, and Tableau dashboards for marketing.

For the first time we actually know who our customers are and what they want. The 25% conversion lift within 3 months of launch exceeded all our expectations.

SAP Central Finance Data Pipeline

The company's SAP Central Finance implementation generated 50M+ financial records monthly across 30+ source systems — but reconciliation was manual, took 2 weeks per month, and had 15% error rates. We designed and implemented a complete Databricks pipeline for SAP CFIN data, including group currency conversion logic, automated MERGE operations, and real-time financial reporting dashboards.

Week 21–28: Financial dashboards, reconciliation automation, UAT and production go-live

Our month-end close went from 2 weeks of manual reconciliation to 2 days of automated processing. The accuracy improvement alone justified the entire investment.

Multi-Cloud Infrastructure Migration

Legacy on-premises data centres across 12 European locations were costing €2M+ annually in maintenance with 94% uptime — below the 99.5% SLA required by enterprise clients. We designed and executed a full migration to a hybrid Azure/AWS architecture, implemented GitOps CI/CD pipelines, and established a centralised monitoring and alerting platform. All 12 locations migrated with zero unplanned downtime.

Moving 12 locations with zero unplanned downtime seemed impossible. The Zeldan Tech team made it look easy — professional, thorough, and incredibly well organised.
