Senior Technical Specialist specialising in legacy modernisation, hyper-automation, and enterprise system consolidation. Expert in optimising Mainframe workloads and refactoring legacy streams to drastically reduce MIPS consumption, while seamlessly deploying MIPS-optimised, browser-agnostic RPA automations. Demonstrated success leading complex data migrations, Micro Focus re-platforming, and exposing Mainframe transactions via web services and RESTful APIs. Combines deep technical execution in BFSI systems with strong governance, Agile leadership, and a proactive approach to risk mitigation and data protection guidelines (GDPR/DORA).
· Architected and delivered complex process optimisations by integrating OCR and Machine Learning to automate unstructured data handling, securing a 3-FTE saving and significantly increasing document throughput. · Automated ad-hoc customer communication workflows to manage over 1,000 monthly triggers, resulting in a direct reduction of 750 manual operational hours. · Engineered end-to-end migration logic within Blue Prism Work Queues to maintain 100% status parity for workflow cases, ensuring seamless synchronisation during large-scale policy data migrations. · Orchestrated platform-wide upgrades to Blue Prism v6.10 and v7.1, ensuring N-1 compliance with organisational security standards and maintaining an audit-ready digital workforce. · Designed and developed browser-agnostic automations to transition legacy Internet Explorer processes to modern web standards, reducing technical debt via optimised object re-mapping. · Optimised digital workforce stability by delivering Small Feature Updates (SFU) and performance enhancements, achieving a 35% reduction in production support tickets and enhanced bot longevity. · Standardised development frameworks using environment Variables, parallel sub-processes and enhanced exception handling (retry, no-retry) which boosted overall bot uptime by 15%. · Leveraged App Modeller to engineer resilient elements for Mainframe screens and web applications, improving legacy application’s interface reliability and reducing automation failure rates by 20%.
· Engineered technical transformations and cost-optimisation measures that achieved ± €250k in annual savings. · Optimised DB2 access paths and refactored COBOL to reduce CPU time of a long-running batch job by ± 25% and lower Service Units (MIPS). · Contributed technical designs and development of major projects policy administrative system consolidation, policy data migration, mainframe re-platforming to Micro Focus COBOL and SVN migration to Git and COBOL upgrade. · Bridged the gap between business operations and technical teams by capturing requirements and architecting detailed functional specifications resulting in increase in workflow efficiency. · Created specification, designed and developed COBOL, JCL, DB2, VSAM, and CICS components for life insurance platforms; ensure high volume batch and online stability. · Tuned JCL and utilities (SORT, IDCAMS, ICETOOL) and maintain DB2 statistics (RUNSTATS/REBIND) to improve throughput and reduce CPU/MIPS. · Designed and maintained TWS/OPC schedules, managed dependencies, special resources, and enabled parallel execution to meet batch windows. · Supported 24x7 mission-critical batch and online processing, diagnosing and resolving production incidents to maintain high system availability. · Coordinated and liaised with scrum teams, system Engineers, DBAs, infrastructure teams and CoE teams. · Modernised customer communications with Thunderhead/SmartComm, deployment automation scripts with REXX, test automation with TOSCA. · Mentored developers on coding standards and performance patterns; SME for EGL and mainframe best practices.
· Delivered mainframe enhancements and defect fixes across COBOL/JCL/DB2 streams with on-time releases (Waterfall SDLC). · Optimised legacy batch logic and DB2 SQL to improve runtime and resource consumption. · Supported QA/UAT with test data creation, environment readiness, and production migration checklists; ensured OMS and audit compliance. · Designed an automated DB2 unloads-to-CSV process for analytics and auditing needs, reducing manual effort and runtime. · Delivered and supported SEPA payment processing solutions on z/OS, ensuring performance, stability, and regulatory compliance. · Managed task allocation, capacity planning, and technical escalations across onsite/offshore teams to maintain predictable delivery.
