How I help

Three areas that connect business with technology and lead from an idea to unambiguous requirements.

A

Technical and business analysis

End-to-end requirements analysis, as-is / to-be analysis, solution concepts, functional and technical specifications, and verification that the delivered solution meets the requirements.

B

Process modeling

BPMN 2.0 and UML, process mapping and optimization (Lean, Six Sigma), UX/IA mock-ups and documentation ready to hand over to delivery teams.

C

Stakeholder workshops

Business and technical workshops, alignment of expectations and translation of business needs into requirements and a backlog.

How I work

Process and change first, technology second

Four steps that structure an implementation and limit costly rework.

  1. 01

    I understand the process

    I start with the goal, the people and the current way of working, not with technology.

  2. 02

    I analyze and model

    I describe the as-is and to-be states in BPMN/UML and point out risks, dependencies and regulatory requirements.

  3. 03

    I run workshops

    I agree the scope with business, IT and compliance until the requirements are unambiguous.

  4. 04

    I support delivery

    I hand documentation and the backlog over to teams and verify that delivery matches the agreed assumptions.

A mindset focused on understanding the process and the change is key to a successful implementation – technology comes next.

Regulations and standards

Regulatory requirements I turn into specifications

Payment regulations and standards I work with when analyzing and designing solutions.

PSD2 / PSD3

PSD2 introduced strong customer authentication and third-party provider access, while PSD3 with the PSR tightens fraud prevention, for example by verifying that the payee name matches the IBAN.

Open Banking

Rules under which a bank, with the customer's consent, shares account data and enables third-party providers to initiate payments through secure APIs.

AML / KYC

The obligation to know the customer and monitor their transactions to prevent money laundering – in practice onboarding, risk scoring and reporting of suspicious activity.

DORA

An EU regulation applicable since 17 January 2025 that requires financial entities to manage ICT risk, report incidents, test resilience and oversee ICT third-party providers.

Polish FSA (KNF) guidelines

Recommendations and announcements from the Polish financial supervisor covering, among other things, IT management and security of IT environments, which I turn into system requirements.

ISO 20022

A structured, XML-based payment messaging standard that replaces older formats, including those used in SWIFT, and demands careful data mapping and validation.

SEPA / SWIFT / Elixir

SEPA handles euro transfers, SWIFT international payments and Elixir domestic interbank settlement in Poland; each has its own formats and settlement windows.

Card and mobile payments

Cards and wallets such as Google Pay or Apple Pay rely on tokenization and strong authentication, and integrating them requires a consistent description of flows and error handling.

Technologies and tools

Technologies I know well

Integrations, data, monitoring and team tooling – without them a change cannot be designed well.

REST / SOAP / GraphQL

Three ways systems communicate: REST is lightweight and ubiquitous, SOAP is formal and contract-based, and GraphQL lets you fetch exactly the data you need.

RabbitMQ

A message broker that decouples systems with queues, so a brief failure of one component does not block the whole process and synchronous communication can become asynchronous.

Apache Kafka

A distributed event-streaming platform that durably stores streams and delivers them in real time to many consumers – a good fit for high data volumes.

Swagger / Postman / SoapUI

Tools for documenting and manually testing APIs, which let me check the contract, error codes and edge cases before a solution reaches production.

SQL / NoSQL / Hive

SQL is for analyzing relational data, NoSQL for flexible data models and Hive for querying Hadoop data warehouses – together they let me assess data quality and consistency.

Grafana / Prometheus / Splunk / Graylog

Prometheus collects metrics, Grafana visualizes them, and Splunk and Graylog aggregate logs – together they show system health and shorten root-cause analysis.

OpenShift / Kubernetes / CI/CD

Kubernetes manages containers, OpenShift adds an enterprise layer and CI/CD automates building and deployment, giving repeatable and safe releases.

Jira / Confluence / Git

Jira organizes tasks, Confluence documentation and Git change history; a consistent workflow reduces requirements chaos and makes decisions auditable.

AI agents and AI tools

AI as support, not a replacement

I deliberately use AI agents and tools to shorten the path from an idea to solid documentation – while keeping expert control and accountability for the result.

  • Support for discovery and regulatory analysis
  • Drafts of documentation and diagrams
  • Data analysis and SQL query optimization
  • Automation of repetitive tasks
  • Requirements consistency checks
