● Developed and maintained backend services for Apple Business Chat, Meta (Facebook & Instagram), Email (via Nylas), and Twitter connectors, enabling seamless communication between brands and their customers ● Delivered key features including Business Updates for Apple Business Chat and the migration of the Email Connector from SMTP to Nylas, improving reliability and message processing ● Collaborated in internal design meetings with product and platform teams to integrate new features across multiple services and authored technical documentation for features, migrations, and recovery processes

● Developed backend services that handled around 50k requests per second, processing and enriching anonymized user interaction data from Klarna’s web and mobile apps, serving over 20 million active costumers ● Built Kafka-based pipelines that consumed event streams, validated incoming data, and enriched it with information from external services before routing it to Klarna’s Customer Data Platform (CDP). ● Ensured full GDPR compliance by enforcing anonymization and secure access controls throughout the enrichment and forwarding process. ● Collaborated with data and platform teams to improve observability, reliability, and performance across distributed backend systems.

● Led implementation of a SCIM API for automated user provisioning and lifecycle management integrated with Azure Active Directory ● Designed and implemented authentication and authorization policies supporting multiple user roles and organizations, enabling users to have distinct privileges across tenants (e.g., Admin in one organization, Responder in another). ● Led a GDPR-compliant user deletion initiative, ensuring compliance with the 'right to be forgotten' principle. Anonymized user data while preserving system workflows. Successfully identified and migrated relevant information across systems and databases ● Designed and implemented an AWS-based ETL pipeline for real-time event handling from MongoDB. Used AWS EventBridge for event categorization and routing to a processing queue. A Lambda function then transformed these events, simplifying data processing for downstream services

● Developed an event-driven microservice to streamline data import from external providers into Alyne. Integrated AWS Kinesis for efficient data streaming and processing. Implemented a workflow to transform data fetched from providers like LeanIX and ServiceNow using JSONata ● Used Node.js worker nodes alongside RabbitMQ to handle resource-heavy tasks via RPC calls, reducing strain on the main worker thread. This led to a 70% speedup in API performance, cutting response time from 150ms to 45ms and preventing timeouts during bulk updates

● Developed a cross-platform app (Android and iOS) to enhance inventory control and tracking, resulting in efficient data import into ERP software ● Implemented a serverless application to streamline the process of finding sales leads and setting appointments, leading to improved lead import into the CRM software
