Who Am I
Bhojraj Chavan
Sr. Software Developer — Walstar Technologies
Full Stack Developer with 2+ years of experience building and shipping SaaS web applications. Strong in React.js, TypeScript, Node.js, and Express.js — including PWA architecture, REST APIs, and AWS. Hands-on experience integrating AI/LLM APIs (OpenAI, Google Gemini, RAG) into production systems. Comfortable in Agile teams and delivering features from concept to production.
I focus on shipping production SaaS that real users rely on — clear APIs, reusable UI, and integrations that hold up under real traffic. Recently that has included AI features in live products, not demos for demos’ sake.
