What I'm looking for

I’m looking for a backend role building reliable, cost-efficient distributed systems with event-driven architectures—ideally where I can productionize AI/LLM solutions and own services end-to-end across architecture, deployment, monitoring, and scaling.

I’m a Backend Engineer with 7+ years of experience designing and scaling distributed systems for high-traffic and SaaS platforms. I build resilient, event-driven architectures—especially for AI-enabled retail products and large-scale OTT systems—owning services end-to-end from architecture and documentation to deployment, monitoring, and scaling.

At Treez Inc., I integrated LLM-based description and vision-driven image discovery agents into catalog onboarding workflows, architected a Retail AI Platform with asynchronous orchestration, and built an event-driven Product Collection Service using AWS EventBridge and SQS (achieving 99.9%+ reliability). I also implement secure REST APIs, AWS Cognito identity with RBAC, and CI/CD pipelines, while leading architecture reviews and design documentation to keep systems aligned to scalability, reliability, and business needs.
