About

Professional summary

I am a Senior Software Engineer with 10 years of experience building production-grade, AI-powered web and desktop applications. I specialize in end-to-end systems that combine modern frontend experiences, scalable backend services, and generative AI workflows.

My core expertise includes JavaScript, TypeScript, Python, React, Next.js, Vue, Node.js, and MongoDB. I design full-stack architectures with an emphasis on clean code, performance, scalability, maintainability, and measurable product outcomes.

I have extensive experience integrating LLMs, Retrieval-Augmented Generation pipelines, diffusion models, and agent-based workflows. I have worked with LangChain, OpenAI APIs, Amazon Bedrock, Pinecone, semantic search, embeddings, context construction, and multi-tool AI orchestration.

I build polished user experiences alongside reliable backend platforms. My work spans responsive web interfaces, Electron desktop applications, REST and GraphQL APIs, asynchronous processing, real-time collaboration, data storage, and cloud deployment.

I value strong engineering quality practices, including automated testing, CI/CD, observability, experimentation, and collaborative delivery with product and design teams. I have consistently delivered intelligent product features that improve user experience and create business value.
