What I'm looking for

I’m looking for a senior Full Stack role where I can own microservices and event-driven systems, improve latency and performance, and automate CI/CD. I want to build real-time platforms with Kafka, Redis, and secure authentication, ideally in a collaborative team.

I’m a Full Stack Developer with 7+ years of experience building scalable backend systems and real-time applications using Node.js, NestJS, and microservices architecture. I’ve consistently improved performance—re-architecting a monolithic Next.js app into decoupled services to reduce response time by 50% and query latency by 63%.

I focus on reliability, secure design, and event-driven systems, with strong expertise in Kafka-based streaming, Redis caching, and CI/CD automation. From reducing data retrieval latency by 40% with real-time MongoDB Change Streams to delivering robot monitoring and alerting with 50k+ telemetry events per day, I aim to build high-scale platforms used by thousands of users.
