About Me

Engineering Scalable, Cloud-Native Systems

I am a performance-driven Full Stack Software Engineer who loves building high-concurrency systems and distributed microservices. My approach centers around creating clean backend architectures using Go (Golang), Node.js, and TypeScript.

I am highly skilled in designing low-latency communication via gRPC/REST APIs, event-driven orchestration using Apache Kafka, and workflow management with Temporal.io. I have hands-on experience managing containerized workloads with Docker and Kubernetes to guarantee high availability.

Whether it's optimizing SQL/NoSQL database performance, preventing system bottlenecks, or establishing resilient CI/CD pipelines, I focus on delivering robust, production-grade solutions.

Distributed Workflow & Project Management System

Engineered a resilient, distributed microservices ecosystem designed for high concurrency. Built core business logic in Go (Golang) and authentication services in Node.js, leveraging gRPC to reduce inter-service latency by ~40%.

Architected fault-tolerant workflows using Temporal.io and established a robust asynchronous event-streaming pipeline via Apache Kafka, which improved write-heavy throughput by 3x and reduced database load by 50%.

Employed a polyglot persistence strategy (PostgreSQL & MongoDB) with Redis caching, resulting in sub-100ms read latency for critical operations. Orchestrated via Kubernetes, ensuring 99.9% uptime. Managed production reliability via full-stack observability (Prometheus, Grafana, OpenTelemetry).

Built a high-performance Next.js frontend utilizing a hybrid rendering strategy (SSG + CSR), achieving a <1.0s LCP and a 90+ Lighthouse performance score via feature-driven modular architecture.
