What I'm looking for

I seek senior engineering roles building cloud-native systems and AI-enabled features, with collaborative teams, strong CI/CD, and opportunities to mentor and modernize platforms.

I am a Lead Java Full Stack Engineer with a decade of experience designing and building scalable web applications, APIs, and enterprise solutions across SaaS, gaming, and insurance domains.

I specialize in robust backend systems using Java and Spring Boot, microservices, and dynamic frontends with React, TypeScript, and Vue.js, and I integrate AI solutions (OpenAI, LangChain, AWS Bedrock) to automate workflows and improve user experience.

I have led modernization efforts, mentored engineers, improved CI/CD and cloud architectures on AWS, and delivered high-availability systems supporting millions of users.
