• Technical Consultant for the Amazon's Ring organization (NASDAQ:AMZN) through Deviget.
• My team was responsible for maintaining and enhancing services that process and store events gathered by the different Ring devices.
• Most relevant contributions:
• Root Cause Analysis for Service Outages: Played a critical role in diagnosing and resolving various instances of service downtime. Addressed scenarios including TCP flooding, maximum PID limits, and memory optimisations to stabilise system performance during high-demand periods.
• Load Shedding: Implemented a reverse proxy in front of the main user-facing service, adding load shedding capabilities. This solution significantly improved service resilience, effectively managing traffic spikes during events like Halloween or large-scale retry storms, preventing instance failures and maintaining service availability.
• Service Migration from API Gateway to Internal Auth Solution: Led a critical migration to align with internal standards. This initiative reduced service costs and enhanced data security by moving to a more protected environment, not exposed to the public internet—thus reducing the risk vector. The migration process was meticulously documented, including key performance indicators, milestones, and a contingency plan, ensuring a smooth transition.
