What I'm looking for

I’m looking for a team where I can build scalable full-stack products, own features end-to-end, and keep improving performance and UX. I want clear ownership, modern tech, and opportunities to grow into AI-enabled systems.

I’m a Full Stack Developer who enjoys turning project requirements into scalable, user-focused products. I’m recognized for clear communication, meticulous attention to detail, and a strong commitment to exceeding client expectations.

As a Software developer Intern at JS TIGERS (Aug. 2024 - ongoing), I analyzed project requirements with cross-functional teams and led the software development lifecycle from ideation to deployment. I designed and maintained scalable web applications, contributing business logic to a website for a 3500 CR valued organization and increasing operational efficiency by 5%.

On my ongoing project, RaxoAi (www.raxo.ai), an AI-powered digital marketing platform, I built features like competitor analysis, product intelligence, ad creation tools, and an AI content writer. I also optimized performance by resolving technical issues and reducing average load time by 5%, using Next.js, React, Redux, Redux-Saga, Node.js, Express, PostgreSQL, and MongoDB.

Previously, at RecoBee Digital Private Limited (Mar. 2024 - Aug. 2024), I improved a movie review website’s user experience and increased site traffic by 10%, while also boosting customer engagement by 15%. Before that at Cessini Technology, I led frontend delivery for Ayatrio—an ecommerce experience with a 10% user engagement rate—and integrated backend services with Node.js and Express. I also bring strong AI & machine learning skills (LangChain/LangGraph/LlamaIndex, RAG systems, and agent development) to help teams build smarter, more responsive applications.
