We help Tier-1 Banking, Defense, Telecom, Public Sector, and Private Equity leaders eliminate Oracle Exadata RAC batch spills, runaway Snowflake and cloud bills, and fragile data pipelines in 4 weeks without big-bang rewrites or junior agency handoffs. Founded in London in 2011, with engineering hubs in London, United Kingdom and Beylikdüzü / İstanbul, Türkiye.
Unify fragmented schemas into a deterministic Data Vault 2.1 warehouse on Snowflake or Exadata and cut 14.5-hour nightly batches down to 3.5 hours in 4 weeks.
Eliminate 18.6 TB/day TEMP spills, fix Smart Scan bypasses, and benchmark zero-copy PyArrow streaming via a self-serve 5-day telemetry diagnostic.
Reclaim ~22% of AWS/Snowflake compute waste and £1M+/yr in Oracle/SQL Server enterprise licensing before renewing vendor contracts.
Ship accredited Packer Golden AMIs in 6 minutes and enforce continuous DDL/PII PR gates and LLM cost ceilings under ISO/IEC 27001 governance.
Download our read-only SQL & AWR diagnostic scripts and 15-point Data Vault 2.1 scorecard with instant access in 60 seconds.
Purchase an immediate 5-day read-only telemetry audit via self-serve checkout with a 3x ROI refund guarantee and zero discovery call.
Hands-on Principal deployment of Exadata DBRM tuning, Data Vault 2.1 marts, or air-gapped CI/CD in 28 days (100% Tier 2 fee credited).
Post-purchase ongoing AWR/Snowflake telemetry governance, automated 3NF/Data Vault PR gates, and quarterly capacity optimization.
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."
To protect 100% principal-led engineering standards, we actively disqualify incompatible engagements before any briefing:

Periscube structures engagements across four sovereign collection points: a free £0 15-point Exadata and Snowflake Waste Auditor, a self-serve £2,000 5-Day Bottleneck Diagnostic requiring zero discovery calls, a £20,000 fixed-scope 4-Week Pilot Sprint, and a £5,000 monthly Principal Architecture Retainer for continuous governance, schema auditing, and FinOps cost control.
Our self-serve 5-Day Bottleneck Diagnostic delivers an executable SQL, DBRM, and dbt remediation plan within five business days backed by a 3x ROI refund guarantee. Full 4-Week Fixed-Scope Pilot Sprints deploy verified production query speedups, auditable Data Vault 2.1 models, and cloud cost reductions inside twenty-eight days.
Never. All Oracle Exadata tuning, Snowflake FinOps audits, Data Vault 2.1 pipelines, and air-gapped CI/CD workflows execute strictly inside your sovereign cloud tenant or on-premise data center. We analyze read-only metadata telemetry without exfiltrating customer personally identifiable information, proprietary source code, or production database payloads.
Every engagement is executed hands-on by Periscube Principal Architects bringing over twenty years of production systems experience at Yahoo, Siemens Mobility, Bank of America Merrill Lynch, and Türk Telekom. We actively disqualify hourly staff augmentation and never delegate your mission-critical architecture to junior contractors or offshore intermediaries.
