What I'm looking for

I seek a hands-on engineering role building scalable, AI-enabled products with emphasis on performance, reliability, and collaborative growth.

I am a full-stack software developer with hands-on experience building AI-driven products and scalable backend systems. I have interned across startups where I focused on improving performance, reliability, and user-facing features.

At RaccoonAI I refactored large-scale pipelines, built a DOCX generation engine, and created a workspace viewer supporting 50+ file formats, improving system visibility and output fidelity. Earlier roles at Pazy, Ekaantik, and Void Star India had me design backend solutions with Java, Spring Boot, PostgreSQL, Neo4j, Redis and deliver full-stack features with React, Node.js and GraphQL.

My projects include CFassist, an accessibility-focused AI visual assistant; Loid, a CLI for publishing to Hashnode; and Hault, a self-hostable AI customer support platform. I emphasize performance improvements, reliability, and user-centered functionality across the stack.

I enjoy applying modern cloud and AI tooling—Docker, Cloudflare, Gemini AI, Azure CV, LangSmith—to solve real problems, and I seek roles where I can continue delivering high-quality software while learning and mentoring within cross-functional teams.
