I am a Senior Software Engineer with 7+ years of experience delivering enterprise-grade, compliant, and scalable solutions in the banking and financial services industry. During my career I specialized in designing, building, and maintaining high-performance backend systems under PSD2 regulations, with a focus on fraud prevention, API security, and financial systems integration.
? Key Expertise
I help organizations design, build, and optimize backend systems that are:
? Key Expertise
- Backend Development: Java 17, Spring Boot, REST APIs, Microservices
- Cloud & DevOps: Kubernetes, OpenShift, Jenkins, Azure DevOps, CI/CD pipelines
- Monitoring & Observability: Grafana, Prometheus, distributed monitoring solutions
- Data & Messaging: SQL Server, Kafka
- Testing & QA: Cucumber, end-to-end automation, performance & resilience testing
- Banking Domain: PSD2 compliance, fraud prevention, account aggregation services, regulatory alignment
- Led development of high-load, low-latency APIs for account verification, enabling banks and PSPs to reduce fraud, block unauthorized transactions, and prevent misdirected payments.
- Migrated core banking applications to cloud-based infrastructure (ICHP OpenShift), improving scalability and resilience.
- Implemented QA automation frameworks with Cucumber/Gherkin, increasing coverage and reducing regression issues.
- Established observability frameworks with Grafana & Prometheus, ensuring SLA compliance and proactive incident management.
- Experienced in production deployments, L3 support, and troubleshooting for mission-critical banking services.
I help organizations design, build, and optimize backend systems that are:
- Secure & Compliant – built with best practices in API security, data protection, and regulatory alignment.
- Scalable & Reliable – engineered to handle high-load, low-latency environments with proven performance.
- Observable & Maintainable – delivered with end-to-end monitoring, CI/CD automation, and robust test frameworks to ensure long-term stability.

Project history
• Member of the VoP Provisioning Team, building services that allow financial institutions, payment service providers, and businesses to verify whether provided account details match registered accounts — reducing fraud, preventing misdirected payments, and blocking unauthorized transactions.
• Designed and implemented end-to-end critical APIs capable of handling very high load and low latency, actively involved in architecture and design decisions as the main technical point of contact.
• Collaborated with Product Owners, Chapter Leads, and Architects to define features, ensure regulatory alignment, and deliver scalable solutions.
• Defined the non-functional testing methodology (performance, reliability, resilience) to validate system behavior under stress.
• Established the monitoring and observability framework using Grafana and Prometheus, enabling proactive incident detection and SLA compliance.
• Performed production deployments and monitoring, providing L3 support, troubleshooting incidents, and resolving client-raised issues in critical environments.
