Real-world technical challenges and solutions
ML-Powered Experimentation Performance Optimization
Optimizely
Challenge
Contextual Multi-Armed Bandit (CMAB) API was experiencing high latency, impacting user experience for thousands of customers running ML-powered experiments. P50 latency needed significant improvement to meet SLA targets.
High-Load Distributed System Resilience
Optimizely
Challenge
Critical AWS DynamoDB auto-scaling issue was affecting a high-load distributed microservices architecture handling an average of 450 requests per second, with spikes up to 45,000 during peak hours. System experienced throttling and degraded performance during traffic bursts.
Legacy System Modernization at Scale
Optimizely
Challenge
Edit Proxy, a core Visual Editor microservice used by thousands of customers, was running on Python 2 (end-of-life). The legacy codebase posed significant security vulnerabilities and compliance risks, blocking critical product updates.
