What I'm looking for

I seek a technical leadership role building scalable, cloud-native microservices where I can mentor engineers, make architectural decisions, and drive reliable CI/CD and observability.

I am a dedicated Full-Stack Software Engineer with deep specialization in Java backend development and strong experience in Python, JavaScript, and TypeScript. I focus on architecting scalable, high-performance systems that power mission-critical business applications.

I have led multiple migrations from monoliths to microservices, applied Domain-Driven Design, and designed schema-driven dynamic UI platforms to enable rapid business adaptation without redeploys. I consistently enforce clean architecture, design patterns, and test coverage through regular code reviews.

In leadership roles I mentor developers, serve as Scrum Master, and guide architectural decisions aligned with business goals. I have implemented CI/CD pipelines, API gateways, observability, auto-scaling practices, and optimized backend search with Elasticsearch and materialized views.

My hands-on technical toolkit includes Spring Boot (reactive and traditional), NestJS, Kafka, Redis, AWS EKS, Docker, and event-driven patterns. I seek to deliver reliable, secure, and future-ready solutions while growing teams and improving engineering productivity.
