Central Service Delivery (CSD)

Worked on the Central Service Delivery (CSD) platform, a large scale public sector digital system built to consolidate multiple municipal and citizen services into one platform. It ran on a highly distributed, serverless AWS architecture, consisting of dozens of microservices and 30+ APIs backed by AWS Lambda, deployed across multiple environments.

Due to the scale and decentralization of the platform, there was no single, reliable way to discover, view, or test APIs per environment. Teams had to guess endpoints, dig through configuration, or run services locally, which significantly slowed down development, QA, and troubleshooting and increased the risk of errors across environments.

• Built a centralized, automated Swagger based API hub per environment, turning a fragmented serverless landscape into one searchable and testable interface.
• Reverse engineered and automated the API documentation pipeline by using AWS API Gateway export capabilities to generate OpenAPI JSON definitions for each microservice at scale.
• Developed a PowerShell automation that exported the full API surface for each service and standardized the output so it could be consumed consistently across environments.
• Rolled the solution into CI/CD, adding a pipeline step for every microservice that generated and published its OpenAPI export into an environment specific S3 bucket.
• Hosted Swagger to automatically aggregate the exported definitions, so new endpoints appeared in the portal as soon as a service was deployed, with zero manual maintenance.
• Delivered a single source of truth per environment where the team could instantly find and test any Lambda endpoint, removing the need to guess URLs, dig through config, or run services locally.

• Built production grade integration flows on Azure Functions with Service Bus and Queues for reliable, decoupled processing.
• Implemented end to end processing for ISO 20022 camt.053 and camt.054 statement files, including XML Schema (XSD) validation, transformations, and safe re processing.
• Delivered accounting automation including General Ledger posting and reconciliation pipelines with full traceability.
• Automated recurring internal file processing daily, monthly, yearly, including customer facing exports and regulated reporting files generated for external authorities such as the Police and the Swedish Tax Agency, as well as compliance heavy workflows including AML related processes.
• Used Logic Apps for file movement and routing across BizTalk servers, transferring files for further processing or archiving, with scheduling and monitoring in place, and APIM to manage and expose integration endpoints.
• Ensured secure, compliant operations using Managed Identity and Key Vault for authentication and secrets management.
• Implemented strong observability with Application Insights for monitoring, troubleshooting, and operational visibility.
• Built Azure DevOps Pipelines with separate deployments per environment, including environment specific configuration and release stages.
• Implemented CI quality gates with SonarQube to catch code smells and reduce risk before promoting changes.
• Delivered an Audit Log integration by consuming audit events from Mambu, transforming and enriching them, and publishing them into Azure Event Hub, where Splunk consumed the stream for near real time monitoring by other teams.

PSD2 (Open Banking)

Worked on a PSD2 Open Banking API platform for a major online Swedish bank, delivering secure and compliant read only access to corporate bank account data via Open Banking APIs based on explicit customer consent and Strong Customer Authentication (SCA), without any payment initiation, while meeting PSD2 security, auditing, and regulatory requirements. The delivery was done within a distributed team across North Macedonia and Serbia.

• Migrated authentication and authorization from IdentityServer4 to OpenID Connect to align the platform with modern security standards.
• Upgraded the full solution from .NET Core 3.1 to .NET 6 to improve performance, maintainability, and long term support.
