Senior Full-Stack .NET developer - 34292
Backend-orientierter .NET-Softwareentwickler mit über 5 Jahren Erfahrung im Aufbau von Systemen für den reibungslosen Geschäftsbetrieb in Microservice- und monolithischen Architekturen. Ergänzend dazu umfassende Full-Stack-Kenntnisse in Angular und React. Sicherer Umgang mit MS SQL Server, PostgreSQL, MongoDB und Redis. Fokus auf die Lösung realer Geschäftsprobleme statt auf Trendverfolgung. Erfahrung mit Azure Cloud-Bereitstellung und -Infrastruktur sowie KI-gestützten Entwicklungsmethoden zur Beschleunigung der Bereitstellung. Übernahme der Verantwortung für den gesamten Entwicklungsprozess von der Architektur bis zur Produktion, Mentoring von Entwicklern und Förderung einer Code-Review-Kultur.
• Solid foundation in data structures, object-oriented design, operating systems, and client-server interaction.
• Hands-on experience building full-stack applications using .NET with relational SQL databases.
• Developed skills in software engineering methodology, git version control and designing scalable architecture.
• Investigated and resolved production incidents using application performance metrics and Graylog logs, improving incident response and system reliability.
• Designed and maintained relational schemas (MS SQL Server, PostgreSQL). Optimized read-heavy and EF Core queries via execution-plan analysis and indexing, cutting query latency by up to 40% and improving server responsiveness.
• Set up real-time Slack alerting for errors, failed jobs and anomalies - cut incident detection time from days to minutes.
• Built Angular frontend with reusable components, reducing code duplication and simplifying API integration.
• Drove code quality and knowledge sharing - applied SOLID and Clean Architecture principles through refactoring and code reviews, making changes safer and easier to deliver.
• Unified 10+ partner integrations into a shared NuGet package (documented in Confluence) - cut new integration development time from 3 days to 5 hours, improved stability.
• Standardized AI-assisted development through repository-level agent instructions, guiding coding conventions, security practices and build/test validation before code review, improving code consistency and reducing review overhead.
• Automated CI/CD pipelines on Azure DevOps, reducing regression testing time by 55% and eliminating manual deployments, enabling 2x more frequent releases.
• Improved system availability by decomposing a monolith into 4 event-driven microservices, using SAGA for cross-service data consistency and the Outbox Pattern for reliable event delivery, eliminating silent message loss.
• Identified and resolved two Azure infrastructure inefficiencies: redesigned polling-based report ingestion as an event-driven Azure Serverless Function and replaced Base64 image storage with Azure Blob Storage with automated Archive Tiering, reducing overall project infrastructure costs by 30%.
• Delivered 5+ production services end-to-end - from requirements and architecture design through deployment and monitoring with Prometheus/Grafana, ensuring production observability and owning the full delivery lifecycle.
• Built React frontend with reusable component architecture, form validation and Redux state management, improving UI flows and reusability.
