About Me

Passionate about Innovation

I'm a Full Stack Engineer passionate about building impactful web applications that solve real-world problems. With a strong foundation in both frontend and backend technologies, I excel at creating seamless, scalable solutions.

Currently working as a Freelance LLM Trainer and Prompt Engineer at Outlier, I help improve AI models by creating challenging coding prompts and providing detailed feedback. Previously, I've worked with companies like Innovapptive, Fize Technology, and Trika Technologies, where I've contributed to building business analytics dashboards, insurance agency platforms, and B2B eCommerce applications.

Beyond coding, I'm an active participant in state-level cricket and believe in maintaining a healthy lifestyle through regular exercise. I'm always eager to learn new technologies and take on challenging projects.
