Sebastian Palm

Led architecture and development of a production AI-powered collaborative editing platform with modular, test-focused design in Swift and SwiftUI. Built a real-time collaboration engine using Swift Concurrency plus WebSockets, including conflict resolution for concurrent edits and AI-generated changes. Implemented an interactive semantic diff/merge and developer workflow, and delivered a browser-based IDE experience. Added backend capabilities for virtual file systems and dependency analysis and maintained release automation with fastlane-based CI/CD.

Built a production threat intelligence and analyst workflow web platform combining real-time telemetry with AI-assisted detections and collaborative investigation tooling. Developed React and TypeScript front ends for high-volume event streaming over WebSockets with buffering and virtualization for responsiveness. Implemented backend microservices in Python (FastAPI) and Go using Kafka, gRPC, Redis, and Kubernetes for low-latency distributed processing. Delivered secure response orchestration APIs with approval flows, audit logging, and RBAC, plus threat correlation views mapped to MITRE ATT&CK.

Built and scaled a digital voucher distribution system processing high volumes of telecom and gift card transactions. Developed backend microservices in Python using FastAPI/Flask with asynchronous processing, idempotent APIs, and transaction optimizations to increase throughput. Implemented a distributed pipeline with Redis locking, retry queues, and dead-letter handling to prevent duplicate PIN issuance. Created a React-based real-time operations dashboard, and improved security and resilience with Docker containerization and CI/CD automation.
