What I'm looking for

I seek to lead development of scalable full-stack and AI-enabled platforms, focusing on backend architecture, data engineering, secure integrations, performance optimization, and collaborative teams that value quality and growth.

I am a senior full-stack web developer and data engineer who builds scalable, high-performance educational and data platforms using MERN, NestJS, Angular, Next.js and robust database architectures. I have architected and implemented RESTful APIs (206+ endpoints), managed PostgreSQL and MongoDB at scale, and executed large data ingestions involving millions of records.

I focus on secure integrations, OAuth2/JWT authentication, CI workflows and rapid prototyping while leveraging AI tools like LangChain and OpenAI for LLM-driven features. I enjoy aligning data architecture with application needs, optimizing performance, and delivering production-ready systems that scale.
