• Designed an AI-assisted deployment verification platform that compresses large-scale production telemetry from Prometheus and Elasticsearch into structured signals, exposing them through an MCP server for automated deployment health analysis. • Built and scaled a distributed VOD transcoding platform across ~200 CPU/GPU nodes, reducing processing time from 3-5 hours to 15-25 minutes and improving content delivery speed for end users. • Improved system availability to 99.99% for millions of daily users by implementing multi-region replication (UA, PL) and AWS S3 redundancy. Reduced latency by ~30% via query optimization and Redis caching. • Designed and operated AWS-based infrastructure, ensuring high availability and scalability across regions. • Developed content protection and fraud detection systems, reducing piracy and illegal restreaming by ~85%. • Owned end-to-end delivery of production systems (~5 months per project), coordinating cross-functional teams and mentoring engineers. • Architected an ad-integration framework that increased ad revenue and improved system extensibility.

• Designed and developed a production-grade system for processing and rendering real-time stock prices for a Swissquote bank. Leveraging a microservices architecture with a message broker, the platform reliably processed tens of thousands of price updates per minute and enabled clients to configure and display pricing data with low latency, improving overall system responsiveness and user experience. • Collaborated closely with stakeholders to gather requirements and ensure alignment with business objectives throughout the project lifecycle.

• Researched and implemented important integration with one of the top stock exchanges from scratch, thereby unlocking access to the profitable Indian and Brazilian markets for the company. • Improved integration with vendors from the UK, USA, India, Australia, Turkey, Poland, China
