Paul Bandler

• Providing part-time architectural and technical consulting, drawing on over 40 years of enterprise platform experience in financial services and professional-services technology.

Deployed across Europe, the Middle East and Australia to c.2,000 clients, supported by a distributed engineering team of c.25 across the UK, Poland, India and Australia. Worked as an individual contributor with a leading role in the platform's architectural direction, alongside the platform's originating partner and a peer development management structure.

• Re-architected core platform metadata storage, moving it out of the relational database — reduced developer effort and defect rate; awarded the highest possible impact rating in an annual performance review as a result.
• Refactored and scaled the batch processing engine to sustain performance as client and transaction volumes grew substantially.
• Introduced REST API capability to the platform and subsequently designed and built a rapid API-development framework to accelerate delivery of further APIs, supporting the platform's integration and modernisation strategy.
• Delivered functional features across the platform's product surface, including data metrics, charting, and batch client-report export.
• Led the team's adoption of agentic/AI-assisted development tooling (GitHub Copilot) and practices; founded and ran a weekly cross-team "Sharpen the Axe" forum for best-practice exchange.
• Delivered platform security and integration workstreams, including penetration testing coordination, Security Design Documentation, and identity (Entra ID) integration testing for an API Enablement initiative.

• Designed and delivered a solution that scaled trade processing capacity from 25,000 to 400,000 trades per day while reducing operating costs.
• Led a green-field rewrite of the C++-based trade validation and enrichment engine using modern Java-based technologies.
• Member of the MiFID II "Change-the-Bank" team integrating middle-office systems with Nomura's firm-wide MiFID II solution.
• Led a small team scaling trade processing capacity further using large off-heap memory-mapped data structures.
• Provided level-3 production support and root-cause investigation for trade booking, accrued interest, and settlement instruction issues.
• Development delivered across a London/Mumbai distributed team, with technical direction and core platform work led from London.

Delivered a 4× throughput improvement on the production codebase using Kafka and VoltDB, and prototyped a Kafka Streams/CQRS-based evolution of the architecture. A technically rich but commercially early-stage venture; scope was limited by the company's stage rather than the work delivered.

• Prudential UK — Software Engineer (Contract), 2004–2007: re-developed data access layer for large-scale annuity pricing engines, improving throughput and scalability.
• Nexagent Ltd — Lead Architect, 2001–2004: founding architecture team member for a network-services start-up; defined J2EE-centric platform architecture.
• Compaq plc — Technical Manager (Contract), 1999–2001; Nortel plc — Senior Software Engineer (Contract), 1998–1999: product engineering roles with two major networking/technology vendors.
• 1983–1998 — Software engineering and product development roles including a c.60-person commercial PC software product development team (Logica/IBM), plus Unisys, HP, and Opal Communications / Open Telecommunications (Australia).
