What I'm looking for

I’m looking to lead backend architecture for enterprise products—designing secure, highly available systems, improving performance with caching/DB tuning, and owning CI/CD and observability from design to production.

I’m a results-driven Senior Backend Engineer and System Architect with 4+ years of experience designing, building, and scaling high-performance distributed systems, multi-tenant SaaS platforms, and event-driven architectures.

I specialize in Node.js, NestJS, and TypeScript, and I’m especially proud of performance work that moves the needle—optimizing PostgreSQL queries and deploying Redis caching layers to improve response times by 40% and support 10,000+ daily transactions.

Across enterprise systems, I’ve led end-to-end delivery—from architectural design through CI/CD deployments, production monitoring, and incident response. I’ve built real-time, event-driven microservices for order and payment workflows, reaching 99.9% uptime while improving resilience through rigorous incident management and release discipline.

When I join, I focus on secure, scalable backend infrastructure: multi-tenant logical isolation, RBAC/permission engines, fault-tolerant designs, and observability (e.g., Datadog). I’m passionate about taking products from solid foundations to highly available, secure platforms that reliably grow with user demand.
