Peadar Murphy FCA · Financial Systems & Data Specialist
I help banks, lenders and financial institutions deliver complex systems change—combining senior-level financial understanding with hands-on work in the underlying data and technology.
What that means in practice:
Finance: A Chartered Accountant who can engage CFOs, senior stakeholders and operational teams on financial logic, delivery risk and business outcomes.
Technology: A hands-on specialist who writes the SQL, builds the scripts, and engineers the data transformations that make the change work.
Since 1997, I’ve delivered core banking, lending, trade finance and loan servicing work internationally—from data migration, reconciliation and cutover to reporting, systems integration and implementation support.
The result: financial meaning preserved through migration, reconciliations that stand up to scrutiny, joined-up systems and reporting people can trust.

DOMAINS I'VE WORKED ACROSS
Techzana provides hands-on execution across financial data, underlying systems, and core logic—delivering the technical rigor needed for complex platform change and regulatory integrity.
Source-to-target mapping, ETL/ELT pipeline construction, financial data cleansing, schema interrogation, and cutover execution.
Hands-on SQL, VBA, Python and MS Access work for rapid diagnosis, automation and resolution of difficult data issues.
Complex general ledger, balance, and transaction reconciliations grounded in direct accounting and financial system logic.
Financial, management, and regulatory data extraction—including monthly Central Credit Register (CCR) submissions, Central Bank analytical returns, automated reporting pipeline development.
Cross-platform financial integrations, API data flows, and semi-structured file parsing.
Development of custom VBA/Web/Python/SQL solutions.
Project-managed approximately 20 institutional loan pool transfers and securitisations over two years, spanning portfolios from under 100 to several thousand loans. Coordinated lending-system changes and cross-departmental delivery from planning through completion.
Built a fuzzy-matching data interrogation and reporting system across multiple sources, enabling accurate postage-cost charge-back to institutional clients. Delivered ~€60,000 per month in previously unbilled charges.
Built and iterated spreadsheet macros, scripts and data tools alongside stakeholders to automate manual work, support implementations and connect disparate subsystems. A consistent pattern throughout my career, built rapidly alongside stakeholders and refined until fit for purpose.
Designed a structured reporting tool for Fusion Trade Innovation, a highly parameterised trade-finance platform. It enabled implementation teams to analyse tens of thousands of configuration points more quickly and systematically than through raw system review.
Built Selenium and Playwright tools to automate repetitive data-entry, navigation and expected-versus-actual validation workflows, making implementation testing faster, more consistent and easier to repeat.
Designed and built bespoke migration applications for country-wide core-banking branch rollouts, moving tens of thousands of bank customers with improved accuracy and speed compared with manual migration methods.
I’m a Fellow Chartered Accountant with 30 years experience in financial systems, beginning in 1997. My edge is that I’m equally comfortable in the data and in the room with the business. I write the SQL and build the migration tools myself, while also being able to discuss the financial logic, operational impact and delivery risk with senior stakeholders. That combination has taken me across 24 countries, through three generations of the same core banking platform, and more recently into an in-house lending system built on a modern web stack.
My work sits across both sides of the table: functional and technical, business-facing and development-facing.
The engagements I’ve valued most are the ones where I’m doing both at once — sitting with the business to work out what a system actually needs to do, then going and writing the SQL, building the reconciliation script, or mapping the legacy data myself, rather than handing that off and waiting for someone else’s version of it. Thirty years of migrations have taught me that’s usually where problems hide: a mapping rule that’s almost right, a reconciliation report that’s a day too slow, a requirement that reads fine in a document but doesn’t survive contact with the actual data.
I’ve also done the full range of business analysis work — requirements gathering, BRDs, incident and root-cause analysis, Agile delivery, project management — and I’ve been the trusted “go-to” person on more than one team for exactly that reason. It’s the combination that clients tend to find useful: someone equally comfortable in either kind of meeting, and equally effective whether interrogating raw database tables or refining a stakeholder’s initial requirement.
I joined Kindle Banking Systems in Dublin in 1997, beginning in software testing before moving into international implementation work. I stayed with the platform through its evolution from Bankmaster and Branchpower to BM+ and Fusion Essence as Kindle became Misys and later Finastra.
Over 23 years, I implemented the platform across Africa, offshore and Gulf financial centres, Europe and Asia, later extending into Finastra Trade Finance in London and Paris. In 2023, I brought the same techno-functional approach to an in-house lending platform built on C#, Angular and SQL Server.
Bridged business and development teams on an in-house lending system.
Built a fuzzy-matching solution delivering approximately €60,000/month in recovered savings.
Project-managed approximately 20 institutional loan pool transfers and securitisations.
Used SQL Server and multi-source data interrogation to reconcile, validate and report on lending-system data—investigating complex data issues, incidents, operational errors and potential breaches; establishing scope, identifying affected accounts and transactions, quantifying impact, and producing evidence for root-cause analysis and remediation.
Supported incident-management and regulatory-reporting processes for Central Bank reportable events, translating investigation findings into clear impact analysis, corrective actions and follow-up controls.
Supported the positioning of regulatory-letter workflows for migration—interrogating source data, defining data and mapping requirements, and validating that customer, loan and event information could drive accurate, compliant correspondence in the target process.
Career break during 2020–2023, with technical currency maintained through personal software and data projects.

Thirty years of financial systems delivery has taken me to 24 countries across four continents—not as a tourist, but on assignment implementing, migrating and troubleshooting core banking, lending and trade-finance systems.
That footprint includes branch roll-outs across Sub-Saharan Africa, offshore and Gulf financial centres, Western and Eastern Europe, India, Hong Kong and Mauritius. It has given me practical familiarity with different regulatory environments, data-quality challenges and stakeholder cultures.
