Achievements

GDPR-compliant Stripe-based KYC and onboarding platform

Led and coordinated a cross-functional team in the design, implementation, testing, deployment, and operation of a GDPR-compliant, multi-country KYC and onboarding platform for trainers, built on the Stripe Connect infrastructure. Demonstrated a strong focus on customer satisfaction, and the ability to make informed technological decisions in defining the long-term business IT strategy
The platform automates the entire KYC and onboarding process in full compliance with country-specific regulations. It securely collects, processes, and stores personal and financial data according to GDPR and industry security best practices. It performs automated digital identity verification, risk assessment, and high-risk profile detection, ensuring compliance and operational integrity across multiple jurisdictions. Additionally, the platform provides integrated tools for trainers to exercise their GDPR rights seamlessly within the system

Stripe-connected digital ledger and payment reconciliation platform

Led and coordinated a cross-functional team of professionals in the design, implementation, testing, deployment, and operation of a Stripe-connected digital ledger and payment reconciliation platform Demonstrated deep technical expertise in defining the next-generation target architecture for financial services and effective communication skills in leading engineering teams through innovation toward digital excellence
The platform provides near real-time tracking of all fund movements between clients, the platform, and trainers. Its distributed, multi-country, multi-entity architecture enables precise modelling of complex business processes and proactive anomaly detection. Serving as the single source of truth and core financial system of record for the entire smart fitness ecosystem, the ledger supports operational issue resolution, client receipts, trainer invoicing, financial accounting, analytics, reporting, and automated alerting on anomalies, ensuring transparency, accuracy, and trust across all financial operations

Federated IAM for instant payment processing

Situation: an instant payments product provides reliable and efficient connectors to different payment schemes along with a unified payment data store that is the single source of truth for all payment processing. Before the change: all access to the payment connectors and the payment data store was managed through manually provisioned generic accounts reused by client bank operators and bank systems
Task: design and implement a federated IAM solution that securely manages access of client bank operators and bank systems to applications and APIs of the instant payments product. The IAM solution should support federated identity management and provide fine-grained access control mechanisms with corresponding security monitoring and access audit functions for client bank administrators
Action: a standard-compliant, reliable, and scalable IAM solution delegates the initial authentication of principals to the bank federated identity provider, as well as supports the adaptive authentication with MFA by requesting additional authentication factors before granting access to sensitive payment information and critical operations. The IAM solution features dynamic, flexible, and fine-grained PBAC fully managed by client bank administrators
Result: the standard-compliant IAM solution provides secure and compliant access of client bank operators and bank systems to the instant payment product applications and APIs. The IAM solution directly contributes to faster time-to-value, reduced operational costs, and increased customer trust by seamless integration with the bank-managed federated identity provider, and dynamic and flexible access policies fully controlled by the client bank administrators

Unified payment data store

Situation: an instant payments product connects to multiple payment schemes e. g. SEPA, STEP1, STEP2, RT1, TIPS. Before the change: each payment scheme had its own scheme-specific payment processing view (operational dashboard). A payment operator had to consult multiple systems during a payment investigation or a manual payment repair
Task: provide a unified view on payment processing under different payment schemes, allow enrichment of standard payment messages with customer-specific data while being compliant with ISO 20022
Action: design and implement a generic relational data model that allows arbitrary typed connections between standard payment messages including non-standard customer-specific data payloads
Result: increased customer satisfaction with the unified view on payment processing across multiple payment schemes, the scalable system-wide transaction log, the single source of truth for payment operations, real-time payment monitoring, and payment analytics

Stable FX pricing and execution

Situation: a cross-border payment service provides very competitive real-time FX rates available to a big bank. However, FX rates are quite volatile and change frequently. Before the change: a real-time FX rate was provided for an initial quote, then an updated real-time FX rate was silently applied to the instructed payment which was totally unexpected to customers. This quickly transformed into a negative feedback and an increased abandonment rate
Task: offer stable FX pricing to customers for the duration (15 mins) of their payment journey from the initial quoting and payment funding through the beneficiary screening and risk assessment to the payment routing and payment execution. The company absorbed the FX loss or gain due to the volatility of FX pricing
Action: design and implement a stable FX pricing for 15 mins with an explicit notification of a customer about a new FX quote after 15 mins if a payment was not yet instructed
Result: increased customer satisfaction and higher usage of the payment service due to elimination of unexpected changes of FX pricing during a payment journey

Automated digital identity verification

Situation: a cross-border payment service provides payment services to a big number of customers in multiple countries (UK, Spain, Belgium). Before the change: a semi-manual process for customer onboarding with manual validation of every new customer. A customer onboarding was finished and the account activated only after a manual check that took 1-2 days. Periodic check of expired customer documents was not feasible for manual processing given a big number of customers
Task: design a seamless and fully automated customer onboarding, automatically collect and verify customer personal data, enough to support AML and fraud checks from the KYC perspective. Automatically build a customer riks profile and calculate a customer risk score. Ensure seamless periodic checks of expired customer documents to stay compliant with regulations
Action: design and implement integrations with country-specific providers of digital identity verification (capture of a national ID or a driver license, matching a selfie with the ID card, a liveness probe) to support a fully automated instant onboarding of low risk customer profiles
Result: increased a lead-to-customer conversion, increased customer satisfaction, decreased abandonment rate due to a frictionless fully automated instant customer onboarding through a digital identity verification, as well as periodic checks of expired customer documents customer personal data
