What I'm looking for

I’m looking to lead full-stack delivery while building intelligent AI-powered features. I want a team that values scalable architecture, clean integrations, strong CI/CD, and close collaboration in Agile product development.

I’m a Senior Full Stack Engineer and AI Developer with 10+ years of experience designing, developing, and optimizing scalable web and mobile systems. I focus on building reliable products end-to-end—frontend experiences, backend services, integrations, and cloud operations.

In my recent role, I planned and engineered full-stack applications across React, Vue, Next.js, Nest.js, Laravel, .NET, and Java (Spring Boot). I also developed AI-powered applications using Python, OpenAI APIs, LangChain, and LLM integration to enhance user experiences. I’ve strengthened high-availability REST and GraphQL APIs with PostgreSQL and MongoDB and scaled microservices on AWS using Lambda, ECS, EC2, and Docker.

I bring deep experience with ERP integrations (NetSuite, Salesforce), building automation with SuiteTalk/SuiteScript, and delivering dependable CI/CD pipelines. I’m at my best leading development in Agile environments—collaborating closely with product and engineering teams while optimizing performance, reliability, and developer velocity.
