Code & Research
Designing High-Scale Performance Systems
Senior Backend Architect
- Led the migration of a legacy monolithic architecture to a high-performance microservices mesh, improving system uptime to 99.99%.
- Engineered a proprietary real-time data processing engine using Go and Kafka, handling over 100k events per second with sub-millisecond latency.
- Introduced automated LLM-based code review agents that reduced pull request turnaround time by 40%.
Full Stack Engineer
- Developed and maintained a suite of cloud-native applications using React, Node.js, and Kubernetes.
- Optimized database query performance for multi-terabyte PostgreSQL instances, reducing average response times by 60%.
- Collaborated with cross-functional teams to deliver a secure, SOC2-compliant fintech platform.
