Big Data Engineering
We turn fragmented legacy data into modern, AI-ready platforms — lakehouses, real-time pipelines and governance, engineered to preserve every record while unlocking new value.
10TB+ daily throughput delivered · 100% data integrity across migrations
Modernise without losing a single record
Decades of business logic, regulatory history and operational knowledge live inside legacy data systems. Throwing them out and starting over isn't an option — but neither is staying stuck on infrastructure that can't power modern analytics, AI or real-time decisioning. Digitec's Big Data practice specialises in the hardest part of the modernisation journey: moving you forward without breaking what works.
We design and execute end-to-end data platform transformations — from on-premise warehouses and brittle ETL pipelines to cloud-native lakehouses on Azure Synapse, Databricks and Snowflake. Every engagement starts with a forensic audit: source profiling, lineage mapping, data quality scoring, and a reconciliation strategy that guarantees row-level integrity through the cut-over.
Beyond migration, we build the foundations that compound value: real-time streaming pipelines with Kafka and Event Hubs, governance and cataloguing with Purview, self-serve BI in Power BI and Tableau, and AI-ready feature stores and vector layers that make every downstream ML and GenAI product faster to ship. The platform becomes a force multiplier — not a maintenance burden.
What we do
A full-stack practice built to solve the hardest digital problems with craft and precision.
Data Modernisation
Migrate from legacy ETL and on-prem warehouses to cloud-native lakehouses. Parallel pipelines and row-level reconciliation guarantee zero data loss during cut-over.
Lakehouse & Warehousing
Azure Synapse, Databricks, Snowflake and BigQuery — modelled, partitioned and optimised for analytics at scale. We build the dimensional models analysts actually want to query.
Real-Time Pipelines
Streaming ingestion with Kafka, Event Hubs and Stream Analytics that powers operational dashboards and ML features. Sub-second latency where the business needs it.
Analytics & BI
Power BI, Tableau and Looker dashboards built around real decision moments — not vanity metrics. Self-serve analytics that executives and operators actually use.
Data Governance
Cataloguing, lineage, quality and access control with Microsoft Purview, Unity Catalog or Atlan. Audit-ready governance without slowing the team down.
AI-Ready Data Layer
Feature stores, vector databases and serving layers tuned for ML and generative AI. Every downstream model ships faster because the data layer is already built right.
How we work
Every engagement follows a battle-tested rhythm — clear, collaborative, and outcome-driven.
Discovery
We profile your sources, map lineage and audit data quality across the estate. The output is a forensic view of where value is trapped and what it will cost to release.
Strategy
We design the target architecture, governance model and phased migration roadmap. Every wave has clear KPIs, reconciliation guarantees and a measurable business outcome.
Build
We stand up the lakehouse, build the pipelines and migrate workloads in parallel runs. Reconciliation reports prove integrity before any legacy system is decommissioned.
Launch & Optimise
We hand over the platform with governance, dashboards and runbooks — then stay on to tune performance, control costs and activate ML and analytics use cases on top.
Why teams choose Digitec
Three reasons clients pick us over consultancies, freelancers and in-house builds.
Zero-record-loss migrations
We've moved 10TB+ daily workloads off legacy systems with row-level checksums and parallel runs that prove integrity before cut-over. Audit teams have signed off the first time, every time.
AI-ready from day one
Every platform we build includes a feature store and vector layer alongside the warehouse. When you're ready for ML or GenAI, the data foundation isn't a six-month detour — it's already there.
Engineered for cost, not just scale
We tune partitioning, caching, file formats and compute auto-scaling so your cloud bill doesn't balloon as data grows. Most clients see 30–60% lower spend than their original quote.
Technologies we master
"Digitec turned a 15-year-old data stack into a real-time AI engine — on time, on budget, with zero downtime."

Common questions
How do you guarantee data integrity during migration?+
We run the legacy and new platforms in parallel, with automated row-level reconciliation and checksum validation between them. No legacy system is decommissioned until the reconciliation report shows zero variance over multiple cycles.
Can you handle on-prem to cloud migrations?+
Yes — most of our engagements move from on-prem or hybrid estates to Azure, AWS or GCP. We've migrated regulated workloads in finance, healthcare and logistics with full audit trails and zero downtime cut-overs.
How long does a typical platform build take?+
First production workload usually goes live in 8–14 weeks. Full multi-source migrations run 6–18 months, delivered in measurable waves so the business sees value early rather than waiting for a big-bang launch.
Will we be locked into one cloud vendor?+
No. We design for portability where it matters — open file formats like Delta and Iceberg, dbt for transformations, and orchestrators like Airflow. Vendor choice is based on your existing footprint and economics, not our preferences.
Do you also build the AI and analytics on top?+
Yes — our AI/ML practice partners on activation, from predictive models and GenAI products to executive dashboards. The data platform isn't the destination; it's the foundation for everything that compounds after it.
