We led data platform architecture for a Tier-1 telco serving 50M+ subscribers. Our team stabilized a petabyte-scale 10-node Exadata 19c RAC and ODI 12c environment. We unlocked +512 CPU threads and eliminated ~18.6 TB/day in temporary tablespace spills. Nightly CDR batch processing shrank from 14.5 hours down to 3.5 hours.
We built the DevOps and data engineering foundation for a £1.6B rail program. The system ingests high-frequency telemetry across 10 fleets and 500+ train units. We automated reproducible CI/CD pipelines and accredited Packer Golden AMIs. Release cycles dropped from 6 weeks to 6 minutes with 400% telemetry scaling.
We architected secure financial data grids and automated BCBS 239 regulatory lineage. At Bank of America Merrill Lynch, we sped up global liquidity sweeps by 5x. During Yahoo's $5B M&A, our FinOps audit recovered ~22% in recurring cloud spend. For the UK Met Police, we saved over £1M annually in database licensing costs.
We deliver production Lakehouse systems and GenAI semantic reasoning platforms.
Our stack pairs Snowflake and modular dbt with DuckDB and Wren AI.
We deploy our tokener gateway for real-time LLM cost governance.
This architecture eliminated database crashes and increased engineering velocity by 10x.
"Periscube's principal architect joined UK Siemens Mobility to help us implement and develop an IoT solutions platform essential for a £1.6 billion commuter rail contract, scaling to 10 fleets and 500+ train units. An invaluable sparring partner for strategy as well as a partner for execution."
"I have had the privilege of working closely with their principal architect on several occasions for the Met Police. Their ability to create complex data solutions and effectively communicate technical concepts to non-technical stakeholders has proven invaluable in bridging IT and business teams."
"They took us from a clunky application release process into an agile CI/CD pipeline and built our observability stack, achieving company firsts and making it easy to get business buy-in. The impact made has created a massive change to how we and our customers work daily."
10x Faster Delivery
Automates Data Vault 2.1 modeling and dbt lineage audits. Runs inside air-gapped data centers or sovereign private clouds.
