<h2 class="link-body-emphasis mb-1">Challenges</h2>
<h4>Scaling an E-Commerce API to Handle Flash Sales</h4>
<p class="">
I designed a distributed rate-limiting system using Redis to throttle traffic while prioritizing high-value requests. Implemented asynchronous processing with Kafka to offload non-critical tasks, ensuring smooth API performance under peak loads. Optimized database queries with caching strategies to reduce latency.
Impact: The system handled 10x traffic spikes with zero downtime during subsequent flash sales.
Conversion rates increased by 15%, and customer complaints dropped significantly.
</p>
<h4>Real-Time Fraud Detection for Payment Gateway</h4>
<p class="">
I developed a real-time fraud detection system using machine learning models integrated with Apache Flink for stream processing. The system analyzed transaction patterns, flagged anomalies, and auto-blocked suspicious activities. Worked with data scientists to fine-tune models for accuracy.
Impact: Fraudulent transactions decreased by 80%, saving millions annually. The system maintained sub-50ms processing latency, ensuring seamless user experience.
</p>
<h4>Overhauling a Monolithic CRM into Microservices</h4>
<p>
I led the architectural redesign, breaking the monolith into microservices using a domain-driven design approach. Introduced Kubernetes for orchestration and CI/CD pipelines for rapid deployments. Implemented an event-driven architecture with RabbitMQ for seamless service communication.
Impact: Deployment frequency increased by 60%, system reliability improved with 99.99% uptime, and development teams became more agile, reducing feature release time from weeks to days.
