What I'm looking for

I seek senior backend/cloud roles where I can lead architecture, mentor teams, and build scalable, event-driven systems in an Agile environment.

I am a Senior Software Engineer with 11 years of experience building high-performance backend platforms, microservices, and serverless solutions using Java, Kotlin, Python, and JavaScript. I have led teams, driven architectural decisions, and delivered event-driven systems that improved performance by 30% and reduced operational costs and deployment time.

I design and implement scalable cloud-native architectures on AWS (Lambda, ECS, Fargate, Step Functions) and manage complex data models across MySQL, PostgreSQL, DynamoDB, and Elasticsearch. I mentor engineers, champion SDLC best practices, and collaborate with product teams to translate business needs into reliable, production-ready systems.
